Abstract

Five new species of Leptoglossus are described: L.caicosensis from Turks and Caicos Island, L. egeri and L. impensus from Bolivia, L. franckei from Costa Rica, and L. polychromus from Ecuador, Cooperative Republic of Guiana (British Guiana), and French Guiana. Leptoglossus argentinus Bergroth is synonymized under L. chilensis chilensis (Spinola) and Narnia anaticula Brailovsky & Barrera under Leptoglossus occidentalis Heidemann. Dorsal view drawings and key to the 61 known species and 1 subspecies are included; a complete checklist, and the position of each species within the species-group defined herein, are given except for two species L. macrophylus Stål and L. polychromus sp.nov., that are insertae-sedis. The pronotal disk, hind legs, and male genital capsule of the new species here described are illustrated.

... Leptoglossus species (Guérin-Méneville) (Hemiptera: Coreidae), also known as leaffooted plant bugs, are endemic to the Western Hemisphere with at least 61 species recorded [1]. The species Leptoglossus zonatus (Dallas) has a broad distribution from the southern portion of North America, through Central America, and into north and central South America [2]. ...
... In 2013, L. zonatus was reported in the northern part of the Central Valley of California [10]. L. zonatus occurs in 13 countries, and of the at least 61 reported Leptoglossus species, is the most widely distributed in the Western Hemisphere [1,21]. The native region where this species has more genetic variability is currently unknown. ...
... Some sample locations in the present study had small sample sizes or one sample was obtained (Nicaragua), which could lead to the overrepresentation of a common haplotype. A larger number of the Leptoglossus species occur in South America [1,2,21]. An examination of L. zonatus genetic diversity from that region could uncover more haplotypes than found in this study, and potentially find a region where there is higher genetic and haplotype diversity for this species. ...

The leaffooted plant bug, Leptoglossus zonatus (Dallas) (Hemiptera: Coreidae) is polyphagous and widely distributed in the Western Hemisphere. Although it has been recorded in California since around 1900, it has become a more common pest in almonds in the last decade. Other studies have shown that an established insect can become a pest when a new genotype is introduced. This study investigated the distribution of two lineages (strains) of L. zonatus in the Western Hemisphere. Specimens from the Leptoglossus collection in the national insect collection in Mexico were used to extract DNA and sequence the mitochondrial DNA cytochrome oxidase I (mtDNA COI) gene, for use in population genetic and phylogenetic analyses. New sequences from Mexico, Central and South America were combined with those available in GenBank, from California and Brazil. Two lineages (strains) of L. zonatus were uncovered. One lineage occurs in California, Mexico and Ecuador. The second lineage is more widespread and found in California, Mexico, Guatemala, Nicaragua, Bolivia and Brazil. The haplotype number and diversity, and nucleotide diversity, were found for samples from California, Mexico, and Brazil, for the two lineages, and for all 118 sequences combined. All sequences combined produced five haplotypes, and a haplotype diversity of 0.54. California and Brazil had 3 haplotypes each, with one haplotype shared (5 total). Haplotype diversity in California and in Brazil were 0.526 and 0.505, respectively. A haplotype network found that one haplotype was most abundant and widespread. The small number of haplotypes, a range expansion, and economic pest status of L. zonatus in California, all contribute to this insect being a potentially invasive insect pest.
... Distribution. A large genus with 61 species and one subspecies widely distributed from southern Canada, throughout the United States, Mexico, Central America, Greater and Lesser Antilles, and South America (Allen 1969, Baranowski & Slater 1986, Packauskas 2010, Brailovsky 2014 Discussion. This species is known by having the thoracic pleura pale yellowish, without contrasting yellowish markings; thoracic and abdominal sterna with with numerous small black dots; a yellowish transverse fascia on corium rectangular, with anterior and posterior margins straight and parallel; posterior margin of pronotum yellow; pronotal disk with a pair of large yellow spots sometimes extensive and coalescing mesally; antennal segments II and III orange with apical third reddish; and humeral angles acuminate, acute and obliquely ascending. ...

A faunistic survey of the Hispaniolan bugs of the family Coreidae is presented based on the study of over 1000 specimens deposited in several entomological collections. The new species Zicca gloriosa sp. nov. is described from the Dominican Republic. Another 12 species are new records for the island, 11 of them being new records for the Dominican Republic: Althos obscurator (Fabricius, 1803), Anasa acutangula Stål, 1870, Anasa tristis (De Geer, 1773), Eubule spartocerana Brailovsky, 1992, Leptoglossus confusus Alayo & Grillo, 1977, Mamurius cubanus Barber & Bruner, 1947, Merocoris distinctus Dallas, 1852, Merocoris typhaeus (Fabricius, 1798), Phthia rubropicta (Westwood, 1842), Sethenira ferruginea Stål, 1870, and Zicca rubricator rubricator (Fabricius, 1803). New records for Haiti are Anasa scorbutica (Fabricius, 1798), Catorhintha selector Stål, 1859, Chariesterus gracilicornis Stål, 1870, Rhytidophthia splendida (Valdes, 1910) and Zicca taeniola (Dallas, 1852). The literature citations presented in Perez-Gelabert (2008) of Leptoglossus cinctus (Herrich-Schäffer, 1836) and Leptoglossus stigma (Herbst, 1784) are probably based on erroneous identifications and not counted as part of the Hispaniolan fauna. The total number of species presently known from Hispaniola is raised to 28. Key to subfamilies, tribes, genera and species are included, as well as color dorsal habitus.
... Commonly referred to as leaffooted bugs due to leaf-like hind tibiae in some species, Leptoglossus is a highly diverse genus consisting of at least 61 species. 1 While members of this highly polyphagous genus are neotropical in origin, Leptoglossus species can be found thriving in a broad range of environmental conditions across all continents except Antarctica. 2−5 As true bugs (Hemiptera: Heteroptera), Leptoglossus possess piercing-sucking mouthparts and engage in extra-oral digestion, injecting proteinaceous saliva 6 into developing seeds, fruit, and vegetative tissues of host plant species. ...
... 2,4 Similarly, L. gonagra, native to North and South America, can be found as far as Asia, Africa, and Australia. 1,3,5 While the invasive potential of some other Leptoglossus species is not well documented, L. clypealis shows evidence of recent range expansion and ecological niche modeling suggests introduction of this species would allow it to become equally, if not more, zonatus support evidence of range expansion and suggest the invasive potential of this species. 33 The invasive potential of L. phyllopus has not been directly studied; however, this species is widespread with populations ranging from the east coast of North America westward to Colorado and California. ...
... Coreids, called leaf-footed or squash bugs, are all phytophagous, and live on plants, feeding above ground 2 in the plant vascular system 8 . The genus Leptoglossus includes 62 species 7 of a neotropical origin, with most species limited to Central and South America 9,10 . A number of Leptoglossus species, including both species that are the subject of this paper, are important plant pests 11 . ...
... Across the insects, the campaniform sensilla usually possesses the same shape and function, although their size may differ in particular species 30 . In some other cases, a group of campaniform sensilla (9)(10)(11)(12)(13)(14) were found on tibia of the cockroach, and trochanter of stick insect in which their nervous response was confirmed when loaded by self-generated or imposed forces (strains) occurring in the exoskeleton 80 . ...

Insecta: Hemiptera: Heteroptera: Coreidae) and a comparison with L. zonatus (Dallas, 1852) are presented. A novel approach that combines the advantages of field emission scanning electron microscopy (FE-SEM) and atomic force microscope (AFM) was used to detail micromorphological structures. A simplified classification system for sensilla that eliminates the subjective aspects of morphology, such as their shape, is proposed. Fourteen sensory organs have been classified into three main groups: (a) aporous sensilla with a flexible socket, (b) porous sensilla with a flexible socket and (c) porous sensilla with an inflexible socket. A large variety of sensory organs (nine types) with olfactory functions are described. The antennal sensory organs have been recognized as one of the factors responsible for the evolutionary success of Leptoglossus spp. and their status as important pests and invasive species.
... Los daños más relevantes consisten en malformaciones de brotes tiernos y piñas jóvenes y la reducción de la capacidad de germinación de las semillas de coníferas (Zhu et al., 2014). Por tal motivo es considerada una plaga forestal en su área de distribución nativa (Rabitsch, 2008;, además de especie invasora en los países donde ha sido introducida (Brailovsky, 2014). ...

New records of Leptoglossus occidentalis Heidemann from Andean region is given, becoming the first occurrence within the province of Chubut. The specimens were collected in different environments of urban and periurban areas -both domiciliary and peridomiciliary-, from Esquel, Trevelin and Aldea Escolar. This report extends its southern distribution area to the parallel 43°S.
... Collected insects were first identified to the family level using identification keys adapted to insects from tropical zones [12,[40][41][42][43][44][45][46][47]. Specimens were identified to the species level by referring to descriptions and figures available in appropriate keys for Coleoptera [47,[48][49][50][51][52][53][54][55], key for Diptera [56], keys for Hemiptera [43,[57][58][59], keys for Lepidoptera [45,46,60,61], keys for Coreidae [62] and keys for Orthoptera [63][64][65][66].

... Wolcott (1936: 170) also reported it as L. zonatus (Dallas) from specimens collected from guava and annato, and Martorell (1976) also lists it as collected from achiote. Together with L. concolor, both L. stigma and L. zonatus belong to the 'Stigma species Group', which is an assemblage of about 20 medium-sized species with dorsally pronged genital capsules, well developed claspers, with both the inner basal lobe and the median lobe on the shank well developed, and a transverse wing fascia, which when present, is irregular (Allen, 1969;Brailovsky, 2014). Two species of this group, concolor and confusus occur in Puerto Rico (Packauskas, 2010). ...
... Leptoglossus concolor can be readily distinguished from stigma by the rough surface texture of the pronotal calli, and for the abundant dark and pale pilosity in the anterior part of the pronotal disc. Also, both of these species are distinguished from the much larger zonatus by an absence of contrasting yellowish and dark areas in the pronotum (Allen, 1969;Brailovsky, 2014). Confirming Martorell's (1976) finding, all MEBT specimens examined are L. concolor. ...

... En los últimos años se ha incrementado la presencia de varias especies de chinches coreides (Hemiptera: Coreidae), de carácter cosmopolita, localizadas en regiones tropicales y subtropicales (Maes y Goellner, 1993) y consideradas muy importantes por su gran diversidad de especies Schuh y Slater (1995). Algunas chinches pertenecientes a la tribu Anisoscelini (Coreidae: Coreinae) denominadas comúnmente (chinches de pata de hoja o chinches patonas) por las dilataciones foliáceas en sus tibias posteriores, poseen una gran diversidad en el hemisferio occidental (Brailovsky, 2014).

Some of the known leaf-footed bugs of the family Coreidae are being considered as invasive species. The authors collected and identified adults of seven species on orange var. Valencia, in the town of Cuauchichinola, Mazatepec, Morelos. Of these three species Leptoglossus zonatus had greater relevance in the collections, followed by two species (Narnia sp y, Leptoglossus concolor). To date, there were no records of incidence of these bugs on the citrus zone in Morelos state, specifically on orange var. Valencia, so it must be monitored and valued as potentially dangerous pests associated with damage and fruit drop in the citrus areas of the state, as well as their possible economic impact

The invasive alien leaf‐footed bug Leptoglossus gonagra (Fabricius 1775), native to the Americas, is herein recorded from South Korea for the first time. Forty nymphs and adults were collected on 22 September 2016 from arable lands of two separate sites. These individuals were identified based on the analysis of morphological characters and cytochrome oxidase c subunit 1 sequences. A neighbor‐joining tree indicated the existence of two clades: Group A from Brazil, and Group B from Asia and Oceania. Mean genetic distance between clades was 8.11%, range 7.60–8.57%. Within clades, mean genetic distance was 0.42% (0.17–0.83%) in Group A and, 0.45% (0.00–0.83%) in Group B. Colonies of 2nd‐final instar nymphs and adults were found, on top of leaves, flowers, fruits, and between the stems of pumpkins (Cucurbita moschata). Nymphs and adults damaged host plants by sucking their leaves, stems, fruits, and buds. After the first discovery in 2016, we were unable to find the bugs again (in 2017–2019). Therefore, the invasion of this species seems to have occurred only temporarily, during the warm season. We suggest that the species may have failed to overwinter as it is normally distributed in regions warmer than Korea. Nevertheless, possible appearances of this species must be continuously monitored as it is a potential pest of various plants cultivated in South Korea.

The western conifer seed bug, Leptoglossus occidentalis Heidemann (1910) (Hemiptera: Coreidae), is a pest causing significant seed damage on many coniferous species. Although it is originally from Western North America, it occurs in several countries today due to frequent intercontinental exchange of related plant material. Both nymphs and adults feed on seeds by piercing their stylet into cones and thus cause conelet abortion and seed loss. Therefore, the western conifer seed bug is expected to have consequences on natural forest regeneration. But its main damage occurs on pine nut production which is one of the most profitable non-wood forest industry in several Mediterranean countries, including Turkey. The western conifer seed bug was first recorded in Turkey in 2009 and it expanded its range rapidly since then. It occurs in all regions of the country today. We named it as “çam kozalak emici böceği” (pine cone sucker bug). We aimed in this booklet to compile a Turkish review of the international knowledge on L. occidentalis produced so far. We also aimed to produce a summary in English which reviews upto date contribution of the Turkish researchers on the pest. Therefore this summary covers only the parts of the booklet related to Turkey. We also provided English versions of the table and figure egends.

Key visual expedite diagnostic features that must be concurrently present of an adult of Leptoglossus occidentalis are: the ivory or pale yellow hemelytral venation, the overall body colour dark reddish brown with pronotum and venter mottled with numerous piceous spots with their humeral angle broadly rounded, and their outer tibial dilations entire not dentate, weakly wider than the inner ones but of equal length occupying less than 70 % of hind tibia (Allen 1969, Brailovsky 2014 (Fig. 2). The outer dilation of L. occidentalis may also be confused with these of Leptoglossus crassicornis, also present in Argentina; these can be differentiated because in L. crassicornis these are more slender and elongate, whereas in L. occidentalis these are widened in the apical section, and less elongated (Faúndez et al. 2018b). ...

Leptoglossus occidentalis (Heidemann) is an invasive species introduced in Europe, Asia, and most recently South America. In the present study, we report the overreaction situation caused by this bug in Chile, as it has been confused with kissing bugs (Reduviidae: Triatominae), Chagas’ disease vectors. During 2018 and first months of 2019, we received 74 alleged cases of kissing bugs to confirm identification. From these, a total of 63 were identified as L. occidentalis, representing a 85% of the total denounces. Additionally, the first bite case in a human is described. The situation caused by L. occidentalis in Chile is discussed, and an illustrated table is provided to correctly identify this species and tell it apart from Triatomines. It is concluded that L. occidentalis is well established in Chile, and it is necessary to educate the population on recognition of the bug and to avoid overreaction as the species can inflict painful bites, but not transmit any disease.

A detailed description of eggs and nymphs of Leptoglossus zonatus Dallas, 1852 is presented. Previously, there were specimens collected from backyard with orange in the provinces of Herrera and Los Santos, which conform the Azuero Region, Panama. Using taxonomic keys of Brailovsky & Barrera (1998), to confirm the identity of 32 adult specimens of L. zonatus, from which four specimens were placed in rearing chambers with washed oranges as food and oviposition substrate. Observation, photograph taking and description immature forms head, thorax and abdomen was made and it was determine that they only survive until the third stage. Eggs are brown, cubic dorsally, arranged in continuous rows of more than 10 units. Nymphs are bright yellow, orange and black, with bulging red eyes, scattered hairs and dorsolateral equidistant projections.
... The presence of cryptic species or genetically divergent strains of either L. zonatus or L. clypealis is suggested by the variation in biological traits such as dietary plasticity and variability in developmental time, such as that observed for L. zonatus raised on Jatropha curcas (Grimm and Somarriba 1999) and Zea mays (Fernandes and Grazia 1992). The two taxonomic revisions of the genus Leptoglossus by Allen (1969) and Brailovsky (2014) are based on anatomical and morphological characters, and currently molecular tools have not been used to investigate variability within the genus or these species. In some insect systems, molecular markers have uncovered that insects with large native distribution ranges can consist of genetically distinct strains or cryptic species, which are morphologically similar but genetically and behaviourally distinct (Herbert et al. 2004, Joyce et al. 2014. ...

Leaffooted plant bugs (LFPBs) (Leptoglossus spp., Guérin-Méneville) (Hemiptera: Coreidae) are large seed-feeding bugs native to the Western Hemisphere. In California, several Leptoglossus spp. feed on almonds, pistachios, and pomegranate and are occasional pests. The objective of this study was to survey the different species of Leptoglossus present in almond, pistachio, and pomegranate orchards in the Central Valley of California. We used two molecular markers, amplified fragment length polymorphisms (AFLPs) and mitochondrial DNA COI, to determine the number of species or strains of each species, and to infer whether individuals of each species move and possibly interbreed with populations from the other host plants. Two species of leaffooted bugs were abundant, Leptoglossus clypealis Heidemann, and Leptoglossus zonatus (Dallas). L. clypealis was collected in almond and pistachio, while L. zonatus was found on all three host plants, but was the dominant species in pomegranate. The AFLP results indicated that L. clypealis consisted of one species, which suggests it moves between almonds and pistachios during the growing season. Mitochondrial DNA COI for L. clypealis found 1-2% divergence between sequences, and a high haplotype diversity of 0.979 with 17 haplotypes. The AFLP results for L. zonatus found two genetically divergent populations which were morphologically similar. The mtDNA COI sequences for L. zonatus were used for haplotype analysis; three haplotypes were found in California, with one haplotype shared with collections from Brazil. The importance of genetic variability and cryptic species for pest management are discussed.

Coreidae is a family of phytophagous hemipterans known as leaf-footed bugs, which can become important pests for various crops. Information on this family in Colombia is scarce, and it is necessary to address its diversity and distribution for adequate management of potential pest species, as well as for the knowledge and conservation of the whole group. To contribute to the knowledge of the family Coreidae in the country, a catalog was carried out based on a review of the bibliography, eleven national biological collections and the citizen science platform iNaturalist. A total of 300 species were found, 115 of which are new records for the country. A key for the genera of Hypselonotini is included, as well as photographs of the habitus of most of the species and distributional maps. Also, a new species of the genus Sundarellus Brailovsky & Barrera from the departments of Guaviare and Meta is described.

In recent decades, the egg parasitoid Hadronotus pennsylvanicus (Ashmead) has gained substantial attention as an important natural enemy of pestiferous leaffooted bug species in the genera Anasa Amyot and Serville and Leptoglossus Guérin-Méneville. Throughout its native range of North America, H. pennsylvanicus parasitizes Anasa and Leptoglossus eggs in various vegetable and orchard systems. The overreliance on broad-spectrum insecticides in these systems and the demand for effective and sustainable coreid pest management strategies have motivated researchers to consider H. pennsylvanicus as an augmentative biological control agent. The potential use of H. pennsylvanicus as a classical biological control agent has also been studied in Europe in response to the rapid spread of Leptoglossus occidentalis Heidemann, an invasive pest causing significant economic losses to the European pine nut industry. Improved understanding of H. pennsylvanicus taxonomy, life history, host range, parasitoid–host ecology, laboratory rearing, and field deployment techniques have created a robust scaffold on which to build future biological control programs. This natural enemy profile reviews the current advances in the aforementioned areas of H. pennsylvanicus research and outlines the parasitoid’s prospects as a biological control agent.

Cowpea plants are damaged by insects in North-Cameroon. During ecological survey (2021 and 2022) in 44 plots of 4x3.5 m each, insects were captured on stems, leaves, flowers and pods, stored in vials containing 70° alcohol, identified in laboratory and the community structure was characterized. We captured 26,015 adults belonging to six orders, 13 families, 19 genera and 19 species. Coleoptera, Hemiptera and Hymenoptera were species-rich orders [five species each (26.3%)]. Hemiptera was mostly abundant (40.0%) followed by Coleoptera (27.6%), Hymenoptera (21.9%), Lepidoptera (0.9%). Heteroptera and Orthoptera were least abundant (0.8% respectively). We recorded five (26.3%) useful species [the West African predator species Cheilomenes sulphurea (Coleoptera: Coccinellidae), and four (21.1%) afrotropical Apidae species [Apis mellifera adamsonni, Amegilla calens, Amegilla sp. and Xylocopa olivacea]], seven (36.8%) phytophagous species [the indomalayan native Aulacophora indica (Coleoptera: Chrysomelidae), Nearctic native Danaus plexippus (Lepidoptera: Nymphalidae), Palaearctic native Dolerus sp. (Hymenoptera: Tenthredinidae), afrotropical native Hypolimnas misippus (Lepidoptera: Nymphalidae), afrotropical native Monolepta marginella (Coleoptera: Chrysomelidae), Palaearctic native Phyllotreta cruciferae (Coleoptera: Chrysomelidae) and the Eurasian native Tettigonia viridissima (Orthoptera: Tettigoniidae)]. We recorded seven (36.8%) sap-feeding species [the afrotropical native Anoplocnemis curvipes (Hemiptera: Coreidae), cosmopolitan Palaearctic native Aphis crassivora (Hemiptera: Aphididae), old world native Bothrogonia sp. (Hemiptera: Cicadellidae), subtropical native Dysdercus cingulata (Hemiptera: Pyrrhocoridae), western Palaearctic native Lagria hirta (Coleoptera: Tenebrionidae), North American native Poecilocapsus sp. (Hemiptera: Miridae) and the Palaearctic native Riptortus dentipes (Heteroptera: Alydidae)]. Giving up eight (42.1%) native species, 11 (57.9%) non-native species and 14 (73.7%) pest species [three natives species (15.8%) and 11 non-natives species (57.9%)]. The abundant species were M. marginella (39.9%), Poecilocapsus sp. (14.4%), Au. indica (11.4%), Ph. cruciferae (10.4%), C. sulphurea (4.6%), H. misippus (3.7%), L. hirta (3.4%), Ah. crassivora (2.4%) while 11 species (57.9%) were rare (<2.2% each). Insects associated with cowpea consisted mostly of non-native species and the situation calls for more research on the bio-ecology of recorded pests. Cowpea plants' insect assemblage mostly presented in 39 Moukhtar Mohammadou et al.: Diversity and Abundance of Pest Insects Associated with Vigna unguiculata (L.) Walp., 1843 (Fabales: Fabaceae) in Bockle and Dang Localities (North-Cameroon) Bockle and Dang, a fairly significant regeneration force (Zipf and Zipf-Mandelbrot functioning models) and all conditions combine to soar. Due to the numerical and behavioural dominance of non-native insects, a significant number of resources are potentially exploitable. In due course, once the invaders would monopolize available resources and saturate the localities, they would not allow native species the niche opportunities to re-establish themselves. The consequences of loosing native species, which may well interact with the endemic flora and fauna, will be of extreme concern.

RESUMEN. El chayote (Sechium edule Jacq.) es un cultivo de importancia económica para México, debido a que es el principal productor y exportador a nivel mundial. A nivel estatal Veracruz (zona centro) es productor del 66 % del total de la producción nacional. A pesar de que este cultivo es atacado por diversas plagas, que se alimentan de diferentes partes de la planta disminuyendo la calidad y rendimiento del cultivo, existe poco conocimiento sobre algunos grupos como las chinches (Hemiptera: Heteroptera). Este trabajo se realizó en la zona centro de Veracruz, en donde se muestrearon 15 parcelas de chayote mediante trampeo cada dos meses durante el año 2018. Un total de 227 individuos pertenecientes a 12 familias, 31 géneros y 43 especies fueron capturados. La familia con mayor número de especies fue Miridae (14 spp.), seguida por Coreidae (7 spp.) y Rhyparochromidae (5 spp.). Otras nueve familias estuvieron representadas por cinco o menos especies. Las especies con una abundancia igual o mayor al 10 % del total de individuos capturados fueron Ligyrocoris litigiosus (Stål), Leptoglossus sp., Fulvius bisbistillatus (Stål) y Lampethusa sp. Las chinches fitófagas representan una plaga potencial para el cultivo de chayote en el centro del estado de Veracruz. Phytophagous true bugs (Hemiptera: Heteroptera) associated with Chayote crops (Sechium edule Jacq.) in central Veracruz, Mexico ABSTRACT. Chayote (Sechium edule Jacq.) is an economically important crop in Mexico, being this country the main producer and exporter worldwide. The 66%, of the total national production, is produced in Veracruz state (central zone). Although this crop is damaged by several pests, that feed on different parts of the plant affecting their quality and yield, little is known about several insect groups such as true bugs (Hemiptera: Heteroptera). This study was performed in central Veracruz, where 15 chayote plots were bimonthly sampled during 2018. A total of 227 individuals belonging to 12 families, 31 genera and 43 species were captured. The family with the highest number of species was Miridae (14 spp.), followed by Coreidae (7 spp.), and Rhyparochromidae (5 spp.). Another nine families were represented by five or fewer species. Species with an abundance equal to or higher than 10%, of the total individuals captured, were Ligyrocoris litigiosus (Stål), Leptoglossus sp, Fulvius bisbistillatus (Stål) and Lampethusa sp. Phytophagous true bugs represent a potential pest for the chayote crop in central Veracruz.

Aims: Because of the problems in agroecosystems following the anarchic use of synthetic insecticides, studies propose an alternative, the use of botanical biopesticides against pests. Study Design: The present study was conducted to evaluate (1) the potential of leaf extract of Calotropis procera (Gentianales: Apocynaceae), Eucalyptus camaldulensis (Myrtales: Myrtaceae) and Tithonia diversifolia (Asterales: Asteraceae) against insects and (2) impact of Apis mellifera (Hymenoptera: Apidae) on Vigna unguiculata (Fabales: Fabaceae) seed yield in North Cameroon. Place and Duration of Study: A field study was set up in 2021 in North Cameroon, during the rainy season. Fourthy four plots of 4x3.5 m each were distributed according to a randomized complete block design model comprising four untreated, four treated using parastar (40EC 535/10/IN, 20 g/l imidaclopride and 20 g/l lamda-cyhalothrine), and 36 plots treated using 10%, 20% and 30% aqueous leaf extracts separately sprayed against Aphis craccivora (Hemiptera: Aphididae). Methodology: Four groups of flowers were randomly selected: (1) free, (2) protected from insects, (3) free exclusively to Ap. mellifera and (4) protected against insects. Results: A total of 10,984 captured flower insects belonged to three orders (Hemiptera, Hymenoptera and Lepidoptera), three families (Aphididae, Apidae and Nymphalidae) and seven species [one (14.3%) sap-sucking Aphis craccivora (Hemiptera: Aphididae), four (57.1%) pollinators Hymenoptera Apidae [Amegilla calens, Amegilla sp., Apis mellifera and Xylocopa olivacea] and two (28.6%) Lepidoptera Nymphalidae [Danaus plexippus and Hypolimnas misippus]. A total of 7,425 insects associated with V. unguiculara corresponded to four orders [Hemiptera (56.7%), Coleoptera (41.5%), Heteroptera and Orthoptera with 0.9% respectively], nine families [Aphididae (45.3%), Chrysomelidae (38.7%), Pyrrhocoridae (4.8%), Coreidae (3.8%), Cicadellidae (2.8%), Coccinellidae (1.9%), Alydidae, Tenebrionidae and Tettigoniidae with 0.9% respectively], 11 genera and 11 species. Conclusion: Apis mellifera was the major pollinator and Aphis crassivora the major pest. The seed yield was improved by 30% extract of plants without impact on pollinators.

The western leaffooted bug, Leptoglossus zonatus (Dallas) (Heteroptera: Coreidae), is a key pest of almonds and pistachios in the USA. With limited monitoring strategies and no economic threshold developed, the use of broad-spectrum insecticides remains the primary control tactic for L. zonatus . In pursuit of more sustainable management options, experiments were carried out to assess the biocontrol potential of the egg parasitoid Hadronotus pennsylvanicus (Ashmead) (Hymenoptera: Scelionidae) against L. zonatus . Biological and demographical attributes of H. pennsylvanicus were evaluated under controlled laboratory conditions. Mated females lived on average 116 days. However, female longevity declined by 74% when provided with host eggs, and by 97% when deprived of a suitable diet. Females produced an average 39.70 offspring, with peak fecundity observed within the first week of their lifespan. The total progeny was on average 92.75% female. Non-reproductive host mortality accounted for > 52% of the total egg mortality observed within the first two weeks, and represented the majority of total host egg mortality thereafter. Age of host eggs did not influence parasitism rates. Under laboratory conditions, H. pennsylvanicus exhibits suitable demographic and reproductive traits as a candidate biocontrol agent of L. zonatus . Further research is needed to determine how to best manipulate and enhance H. pennsylvanicus populations to promote biocontrol of L. zonatus under field conditions.

A survey of leaf footed bugs (Hemiptera: Coreidae) was conducted in two hilly districts of Nepal viz. Lamjung and Kaski, over a period of 13 months (April 2017-May 2018). The prime purpose of the research was to find out the Coreidae diversity in these regions which hasn’t been done before. Sundarbazar, Kunchha and Dura Daanda areas from Lamjung and Hemja and Sarangkot from Kaski were explored. A total of 111 specimens of Coreidae were collected from altitude varying from 700-1600 masl. Eleven different species of these bugs from 1 subfamily, 7 tribes and 7 genera were recorded. All the species fell under single subfamily Coreinae Leach, 1815. One species, Acanthocoris scabrator (Fabricius, 1803) fell under the tribe Acanthocorini Bergroth, one species, Leptoglossus gonagra (Fabricius, 1775) fell under tribe Anisoscelini Laporte, one, Cloresmus khasianus (Distant, 1901) under Cloresmini (Stal) and one, Dalader acuticosta (Amyot & Serville, 1843) under Daladerini Stal. Similarly, 3 species viz. Cletus bipunctatus (Herrich-Schäffer, 1840), Cletus pygophorus (Gupta & Singh, 2013) and Cletus trigonus (Thunberg, 1783) fell under the tribe Gonocerini Mulsant and Rey. Likewise, 3 species were found under the tribe Homoeocerini Amyot and Serville viz. Homoeocerus (Anacanthocoris) striicornis (Scott, 1874), Homoeocerus (Anacanthocoris) sp. and Homoeocerus (Tliponius) unipunctatus (Thunberg, 1783) and 1 species, Anoplocnemis phasianus (Fabricius, 1781) was found under Mictini Amyot and Serville.

The leaffooted bug, Leptoglossus zonatus (Heteroptera: Coreidae), has become a key pest of almonds, pistachios, and pomegranates in California. Adults and nymphs directly feed on nuts and fruits, which reduces crop yield and quality and can facilitate pathogen infections. Current monitoring strategies require growers to actively sample the tree canopy, with no economic thresholds being developed for this pest. To improve monitoring of L. zonatus, a three-year study was conducted to identify an optimal trap. A hanging cross-vane panel trap was identified as the best trap type in Year 1, and subsequent work in Years 1–3 focused on refining its use by modifying surface texture and color. Results indicated that coating trap surfaces with the lubricant fluon improved trap catching ability, and adults were most frequently recovered in yellow traps. A hanging cross-vane panel trap with these features could serve as the basis for the development of a new monitoring system for this pest in orchards, which could be improved further if semiochemical lures will be developed.

Leaffooted bugs (Leptoglossus spp; Hemiptera: Coreidae) are phytophagous insects native to the Western Hemisphere. In California, Leptoglossus clypealis and Leptoglossus zonatus are occasional pests on almonds. Early season feeding by L. clypealis and L. zonatus leads to almond drop, while late season feeding results in strikes on kernels, kernel necrosis, and shriveled kernels. A field cage study was conducted to assess feeding damage associated with L. clypealis and L. zonatus on four almond varieties, Nonpareil, Fritz, Monterey, and Carmel. The objectives were to determine whether leaffooted bugs caused significant almond drop, to pinpoint when the almond was vulnerable, and to determine the final damage at harvest. Branches with ~20 almonds were caged and used to compare almond drop and final damage in four treatments: (1) control branches, (2) mechanically punctured almonds, (3) adult Leptoglossus clypealis, and (4) adult Leptoglossus zonatus. Replicates were set up for eight weeks during two seasons. Early season feeding resulted in higher almond drop than late season, and L. zonatus resulted in greater drop than L. clypealis. The almond hull width of the four varieties in the study did not influence susceptibility to feeding damage. The final damage assessment at harvest found significant levels of kernel strikes, kernel necrosis, and shriveled almonds in bug feeding cages, with higher levels attributed to L. zonatus than L. clypealis. Further research is warranted to develop an Integrated Pest Management program with reduced risk controls for L. zonatus.

The first step to understanding the species present in a particular area is to perform inventory and assemblage studies. To obtain a species inventory, it is important to determine parameters such as species richness and relative abundance. This information can be useful for future studies and decision-making purposes in the conservation area. Despite the fundamental role of the terrestrial Heteroptera in ecosystems, they remain poorly known. We expected that the terrestrial Heteroptera species assemblage would be strongly associated with plant communities. Presently, 840 samples were collected in northern Argentine Patagonia during two years, 2013 and 2014. A total of 1950 adults of terrestrial Heteroptera belonging to 12 families, 32 species, and 8 morphospecies were found. Various statistical techniques were applied to correct the observed data for undersampling bias. These suggested that the lower boundary of the summer Heteroptera species richness in northern Patagonia was about 44-54 species. We concluded that the high regional habitat heterogeneity along the west-to-east and south-to-north gradients was paralleled by the turnover of Heteroptera. However, the Patagonian steppe shared a high number of species with the Monte and Subantarctic provinces. The suction sampling technique is an efficient technique to collect Heteroptera in environments with different plant structure and should thus be used in a complementary way with the sweeping technique.

Cytochrome c oxidase subunit I gene (COI) sequences of roughly 509 bp length for various species of the Infraorder Pentatomomorpha were generated. K2P divergences within and between species and genera were calculated and compared using newly generated sequences and the ones available on online portals. Mean interspecific (within-genus) genetic divergence (14.23%) was ∼ eight times greater than mean intraspecific (within-species) divergence (1.79%). Distance-based as well as character-based approaches were used towards constructing (COI) trees. In total, 20 sequences were of the species that were previously not part of the Barcode Of Life Database (BOLD), hence representing additions to the barcode library of Indian Heteroptera. Some of the analyzed species are well-known agricultural pests. All the COI sequences and the associated specimen data have been deposited on BOLD.

The aim of the present study was to determine the species belonging to Hemiptera ordo between 2016 to 2017 years in Elazığ in Turkey. During the present study, Leptoglossus occidentalis (Heidemann, 1910) (Heteroptera: Coreidae) was collected and attracted our attention. The species was collected for the first time in Elazığ province as a result of this study. This was the first record outside of the western, middle, south and north region of Turkey. The distance to which the species was located was about 450 km away from Kayseri, the closest location where it was previously found. The fact that it was an invasive and harmful species to forest areas and trees, is an important factor for the active investigation of this species. In addition, it is believed that the species has been introduced into the region on the pine trees that are brought from outside. It is also considered that the species will spread to wider regions including East and Southeastern Anatolia in the following years.

Brazilian peppertree, Schinus terebinthifolia Raddi (Anacardiaceae), is a South American plant that is highly invasive in Florida. The impact of insect herbivores on the performance of Brazilian peppertree was evaluated at two locations in Florida using an insecticide exclusion method. Although 38 species of insect herbivores were collected on the invasive tree, there were no differences in growth or reproductive output of insecticide protected and unprotected trees, providing evidence that insect feeding had no measurable impact on tree performance. The majority of insects collected on Brazilian peppertree were generalists, and several were serious agricultural pests.

Finally, Orsillus depressus Dallas, 1852 (Lygaeidae) is recorded for the first time for the north of the province of Buenos Aires. It is commented briefly in each case on their habits as well as their general distribution, that in some cases will be new contributions for other Argentine provinces. Images of each of them are also offered.

Coreidae es una familia de hemípteros fitófagos conocidos como chinches patas de hoja, que pueden llegar a constituir plagas importantes para diversos cultivos. La información de esta es escasa en Colombia, siendo necesario abordar su diversidad, distribución y relaciones ecológicas para un adecuado manejo de las especies potencialmente plagas, así como también para el conocimiento y conservación de todo el grupo. Para aportar al conocimiento de la familia Coreidae en el país, se realizó la revisión taxonómica a partir de la revisión de bibliografía, once colecciones biológicas nacionales y de la plataforma de ciencia ciudadana iNaturalist. Fueron encontradas 301 especies de las cuales 122 son nuevos registros para el país. Se analizaron los patrones espaciales de muestreo y de riqueza de especies. Se proponen claves dicotómicas para la identificación de los géneros de cada tribu, son incluidos además una reseña histórica del estudio de esta familia en Colombia, un catálogo fotográfico con la mayoría de las especies, mapas distribucionales y datos sobre las especies de plantas asociadas. Asimismo, se describe una nueva especie del género Sundarellus Brailovsky & Barrera de los departamentos de Guaviare y Meta.

The 'western seed bug', known as Leptoglossus occidentalis , is considered a global invasive species that has experienced a recent rapid expansion worldwide, becoming an important pest species for coniferous forests. With the 'Canary Islands early-warning network for the detection and intervention of invasive exotic species' (RedEXOS), this species was detected for the first time in the Canarian rchipelago in an urban area in the eastern part of the sland of Gran Canaria. This early detection is crucial for understanding the potential damage in one of the islands with the highest surface area of natural endemic pine forest.

A detailed description of the labial sensory organs of Leptoglossus occidentalis Heidemann, 1910 and L. zonatus (Dallas, 1852) (Hemiptera: Heteroptera: Coreidae) is presented. The detailed morphology, location, and distribution of different sensilla types on mouthparts were investigated and shown in micrographs taken with a scanning electron microscope. Nine types of aporous sensilla, and three uniporous sensilla were found. The possible functions of these sensilla as well as similarities and differences between the mouthparts of Leptoglossus and those of other terrestrial Heteroptera are discussed. The tip of the labium constitutes a functional “touch and taste area”, combining the chemosensitivity of uniporous sensilla P1–P3 and the mechanoreceptivity of A8 and A9 hair-like sensilla. A set of two cone-like chemosensilla types (9 + 2) was found on each lateral lobe of the labial tip. Literature analysis showed that such a set of cone-like sensory organs on the labial tip may be common in terrestrial Heteroptera. This observation confirms that the number and arrangement of sensilla is conservative and can be important in diagnosing taxa at various levels and in phylogenetic studies based on morphology.

Almond, Prunus dulcis (Miller) D. A. Webb, is an important tree nut crop cultivated primarily in the Mediterranean climatic regions. However, the United States, specifically the state of California, is the largest producer and exporter of almond nuts in the world. At least 60 species of insect pests attack almonds worldwide. Hemipterans can be important pests in almond orchards. Some hemipteran insect pests in almonds include lace bugs, plant bugs, stink bugs, and leaffooted bugs. These pests use needle-like mouthparts to pierce and feed upon fruits or other parts of the plant, causing direct or indirect crop damage. Nonetheless, the biology, life history, and management practices for many hemipteran pests of almonds are not available in the literature or come from research of these insects on other crops and host plants. In this article, we discuss the current understanding of biology, ecology, and management of hemipteran pests of almonds and outline future research to advance the integrated pest management of these pests in almond orchard systems.

Among the 32 tribes of Coreinae currently recognized, Spartocerini comprises 66 extant species distributed in six genera: Euagona Dallas, Eubule Stål, Menenotus Laporte, Molchina Amyot & Serville, Sephina Amyot & Serville and Spartocera Laporte, distributed exclusively in the Western Hemisphere. We performed cladistic analyses using equal (EW) and also implied weighting (IW) based on 56 terminals (23 belonging to the ingroup) and 115 morphological characters, including male and female genitalia. Spar-tocerini was polyphyletic both under EW and IW because Molchina was nested in Mictini. We remove Molchina from Spartocerini and consider the genus as incertae sedis. Spartocera, Eubule, and Sephina were not recovered as monophyletic. Sephina pubera (Erichson) is considered as incertae sedis within Spartocer-ini, Eubule ampliata (Valdés) is transferred to Spartocera as a new combination, and Mamurius is included in Anisoscelini.

The western conifer seed bug, Leptoglossus occidentalis Heidemann (1910) (Heteroptera: Coreidae), is a pest causing significant seed damage on many coniferous species. Although it is originally from Western North America, it occurs in several countries today due to frequent intercontinental exchange of related plant material. Both nymphs and adults feed on seeds by piercing their stylet into cones and thus cause conelet abortion and seed loss. Therefore, the western conifer seed bug is expected to have consequences on natural forest regeneration. But its main damage occurs on pine nut production which is one of the most profitable non-wood forest industry in several Mediterranean countries, including Turkey. The western conifer seed bug was first recorded in Turkey in 2009 and it expanded its range rapidly since then. It occurs in all regions of the country today. We named it as “çam kozalak emici böceği” (pine cone sucker bug). We aimed in this booklet to compile a Turkish review of the international knowledge on L. occidentalis produced so far. We also aimed to produce a summary in English which reviews upto date contribution of the Turkish researchers on the pest. Therefore this summary covers only the parts of the booklet related to Turkey. We also provided English versions of the table and figure legends.

p> En tiempos actuales de avance vertiginoso de la ciencia y la tecnología, nos encontramos en una sociedad del conocimiento. En este marco, la investigación científica, como actividad intelectiva, está orientada, principalmente, a la producción de nuevos conocimientos científicos y a la solución de los problemas, generando el desarrollo y progreso de la sociedad. No obstante, también ha conllevado incomprensión, intolerancia, discriminación y destrucción. Recuérdese, por ejemplo, que la invención de la bomba atómica trajo consecuencias fatales como la destrucción de las ciudades japonesas de Nagasaki e Hiroshima y la muerte de miles de seres humanos. Asimismo, los casos de procreación de un ser humano en probeta, la manipulación de los genes de las personas o la clonación que son acciones conducidas por la investigación, lidian con la ética. Entonces, la investigación científica sobrelleva al desfase entre el gran avance de la ciencia por un lado y los valores, por otro. La investigación científica se construye sobre la base de un conjunto de valores epistemológicos y sociales. Según Galán (2010: 1-2), para que la investigación pueda considerarse científica, se debe basar en una serie de valores que surgen del mismo carácter de la ciencia, cuyo fin es la búsqueda de la verdad objetiva. Algunos principios a tener en cuenta para llevar a cabo una investigación éticamente desarrollada son el conocimiento, el placer y el bienestar. Ahora vivimos en un mundo basado en la investigación y gobernado por ideologías fundamentadas en la ciencia y en el uso de instrumentos creados por la ciencia. Sin embargo, es necesario tener en cuenta que dichas ideologías e instrumentos pueden ser utilizados de forma objetiva o subjetiva, correcta o incorrectamente; es decir, de un modo ético o no. En suma, si bien la ciencia moderna a través de la investigación genera mayores logros a la humanidad, es importante tener en cuenta los aspectos éticos en la investigación para que sus resultados sean correctamente utilizados. </p

Described in 1910 from California, Colorado, New Mexico, Oregon, and Utah, Leptoglossus clypealis Heidemann was known as far east as eastern Missouri by the early 1940s; it was recorded only recently east of the Mississippi River (Illinois). Based mainly on images posted on BugGuide, its eastern North American range can be extended in the United States to New Jersey, Virginia, and North Carolina; an Ontario record is the first for Canada. Additional new state records and new localities in previously recorded states are presented. The eastward spread of L. clypealis is compared with that of a congener, L. occidentalis Heidemann. As a strong flier, L. clypealis might have undergone a gradual eastward spread, but the extensive planting of eastern redcedar (Juniperus virginiana L.) for shelterbelts in the Great Plains during the 1930s might have triggered increases in the coreid's population densities, enhancing the probability of further eastern spread. Long-distance dispersal aided by winds and transport via cargo and motor vehicles might also have been involved in its recent range expansion. Nymphs of L. clypealis were observed on five species of the coniferous genus Juniperus (54 sites), mainly on fruitbearing trees of J. scopulorum Sarg. and J. virginiana; adults were collected on two additional species of juniper at five sites. The coreid was found on a eudicot, the anacardiaceous shrub Rhus aromatica Aiton at three sites.

Background: Although Leptoglossus zonatus is considered a secondary pest of maize grown for grain, when grown for seed, this pest can cause significant economic damage. There are no records of management recommendations for this pest. The objectives of this work were to quantify losses caused by L. zonatus to different genotypes used for seed maize production and to estimate the acute toxicity of select insecticides to L. zonatus using different application technologies. The ultimate goal was to calculate economic injury levels (EILs) and develop economic thresholds (ETs) for L. zonatus infesting seed maize. Results: EILs and ETs varied, respectively, from 3-8 and 2-6 adults 1,000 plants(-1) , depending on the genotype insecticide and application technology. Effective control was obtained by using aerial or ground application of λ-cyhalothrin (10.6%) + thiametoxan (14.1%) or permethrin (38.4%) at the rates of 1.48 mL ha(-1) and 27.10 mL ha(-1) , respectively, or ground application of methomyl (21.5%) at the rate of 244.06 mL ha(-1) . Conclusion: Maize grown for seed is susceptible to L. zonatus damage during reproductive stages, and the pest densities requiring management vary with genotype, insecticide, and application technology. These results provide significant contributions towards IPM for seed maize.

In our day, thanks to high-speed transport systems, people are moving living species (intentionally or not) across ecosystems and countless borders. As we know, most introduced species usually do not survive, because they find neither a tolerable environment nor an available ecological niche. Sometimes, successful establishment may also require multiple introductions (Balcom 2004). Of those species that do become established, only a limited number spread and become damaging. Such invasive species are a major threat to our environment because they not only may replace native species (especially beneficial ones) but sometimes they even can change an entire habitat, severely reducing its structure and diversity. Their full effects often are not detected, because the invasion process usually is very long and goes through a series of stages, such as import, release or escape, establishing a population, spreading, becoming a problem, and others (Balcom 2004, Williamson 2006). Moreover, the place of origin of an alien species also plays a role in the process of establishing a population in a new habitat; in Central Europe (i.e., Austria and Switzerland, where the studies were conducted) among the alien intercepted insects, 40% were associated with commodities from Asia, 32% from other European regions, and only 2% from North America (Kenis et al. 2007). Therefore, any new European record of invasive insect species originating from North America is of a great importance, because it helps to document its spreading in a new environment and facilitate preparation for its controlling. One recent introduction from North America to Europe was that of the western conifer seed bug (Leptoglossus occidentalis Heid.). It was originally restricted in its distribution to the western United States, Canada, and Mexico, and is considered a severe pest on conifer seed orchards; it sometimes also causes serious alarm in the autumn, when large numbers of adults suddenly invade houses looking for overwintering sites (cf. Mitchell 2000). In Europe, the species was first established in 1999 in northern Italy, where it was accidentally introduced to different localities (Taylor et al. 2001, Tescari 2001, Villa et al. 2001). Then the species quickly expanded its range towards the west and north of the continent; over a period of eight years it had invaded Slovenia, Croatia, Hungary, Switzerland, Austria, Germany, and Czech Republic to the north, and France to the west (Gogala 2003, Jurc & Jurc 2004, Tescari 2004, Rabitsch & Heiss 2005, Harmat et al. 2006, Kment & Baňař 2007, Moulet 2006, Werner 2006, Dusoulier et al. 2007); in 2003 it was also independently recorded in Spain (Ribes et al. 2004, Ribes & Escol ŕ 2005). In early 2007, it was unexpectedly collected at Weymouth College in England (Malumphy & Reid 2007), and a few months ago it was found also in Belgium in Oostendse (information posted on the 16th of October 2007 to http://www.zwvlkoepel.be/iwg; and Aukema & Libeer 2007). In contrast to all previous records (except that from Spain), because of the place of collecting, the latter two might suggest two independent introductions rather than invasions from southern Europe. Recently, in October 2007, two populations of this species were recorded in the southern part of Poland (Lower Silesia: Wrocław, on a building's window, close to a group of Pinus strobus, 18.10.2007, leg. J. Gubernator - see Photo; Cracow-Wieluń Upland: Miechów near Cracow, on window sill, 10.10.2007, leg. J. Szafarska, groups of Pinus silvestris nearby). These are the first records of this invasive bug in Poland. The available evidence (especially the collecting sites, present area of species distribution, and the speed of spread - see Dusoulier et al. 2007) suggest that L. occidentalis entered Poland from the Czech Republic, where it too was recorded for the first time in 2007 (Kment & Baňař 2007), and where it has quickly spread its range furtherto the north. The species is quite easily distinguished from all other Central European species of the Coreidae, because of its reddish-brown body with a white zig-zag line across the center of the wings, and the characteristic expansions on the hind tibia (see the Photo). In its natural habitat the nymphs and adults spend the summer on pines and other coniferous trees, feeding on green cones and needles, causing a high incidence of conelet abortion and a reduction in the yield and quality (vitality) of seeds. As the weather cools in September, western conifer-seed bugs search for sheltered places to hibernate, and therefore are often seen around homes in the autumn. Its host plants include white pine (Pinus strobus), red pine (Pinus resinosa), Scots pine (Pinus sylvestris), Austrian pine (Pinus nigra), mugo pine (Pinus mugo), lodgepole pine (Pinus contorta), white spruce (Picea glauca), Douglas-fir (Pseudotsuga menziesii), several other conifers, and pistachio (Pistacia vera) (Rice et al. 1985, Blatt 1994, Bates 2000, Mitchell 2000). When we consider the speed of spread of this invasive species (Dusoulier et al. 2007) and the area of its host plants occurrence in Europe, we can ask what happens when this introduced species is successful in its new European habitats. Unfortunately, because L. occidentalis has only recently arrived in the "old continent," only its first records in different countries were usually documented, so far. Nevertheless, we should realize that any new species takes up space and food resources and therefore has some effect on a local ecosystem; the scale of the consequences can depend on the population size the invader reaches, which could lead native species to be displaced to less optimal niches, or to the local extirpation of the native species altogether. For the next few years, more detailed research on the population biology of L. occidentalis in Europe instead of just documentation of new European country records should be emphasized. National Plant Protection Organisations in different European countries should cooperate in conducting a survey of the distribution and population characteristics of this true bug, as was done in the Netherlands and Belgium for the invasive New Zealand wheat bug Nysius huttoni White (Hemiptera: Heteroptera: Lygaeidae) (Smit et al. 2007). If appropriate measures are not taken, L. occidentalis may indeed spread over all Europe; then we will not only have a beautiful "tropical-like species" to admire (Fig. 1), but a regularly breeding invasive species making changes in our coniferous forest ecosystems.

Leptoglossus katiae Schaefer and Packauskas, n. sp., is described from northeastern Brazil. It belongs in the L. cinctus species group and is most similar to Leptoglossus cinctus (Herrich-Schaeffer), L. crassicornis (Dallas), and L. fasciatus (Westwood). It can be distinguished from these species, and from most other Leptoglossus species, by its small size (10.5–12.3 mm) and long rostrum (reaching onto the sixth abdominal sternum), as well as by other characters. Sexual dimorphism of the hind tibia and femur is discussed briefly.

Studies on the New World Coreidae have languished for more than a century. Neglect of these often large, abundant, and occasionally economically important bugs has been due, I believe, to the lack of means to identify them. Most literature treating the New World Coreidae has been restricted to the North American fauna, except for the recent efforts of Brailovsky (1975 to 2007).
