Tettigonia viridissima is a species that is widely distributed throughout the Palearctic. For decades it was assumed that the eastern range limit of the species reaches until the Pacific Coast of the Eurasian continent. However, STOROZ-HENKO (1994) provided evidence for the assumption that T. viridssima reaches its eastern distribution border at th...

... General distribution and biology. Tettigonia viridissima is a large insect widespread in the Western Palaearctic and Central Asia (Rhee 2013). It lives in tall herbs and dense vegetation, feeding mainly on other insects, including toxic Zygaenidae . ...
New chorological data on some species of Orthoptera from the Italian region Molise are given, and 11 species are recorded as new for this area. Moreover, an updated checklist of the Orthoptera thus far recorded from Molise is provided.
... Many orthopteran species perform cryptic coloration following this strategy (GWYNNE 2001, BENTON 2012. Tettigonia viridissima is a large and widely distributed European bushcricket species (RHEE 2013, GRZYWACZ et al. 2017). As the scientific name "viridissima" (= very green) and the common name "The great green bush-cricket" imply, the species has typically and mostly a green body coloration in their natural environment (DETZEL 1998, SCHLUMPRECHT & WAEBER 2003, PFEIFER et al. 2011, BENTON 2012. ...
The coloration of Tettigonia viridissima is mostly green. However, among animals reared in the laboratory, a high percentage of brown individuals was discovered. This unusual coloration is discussed favouring the idea of multiple reasons.
... Tettigonia viridissima (Linnaeus, 1758) has a very wide distribution which covers the Palaearctic and pars of Oriental regions, where it is one of the commonest bushcrickets. According to Rhee (2013) the tegmina of T. viridissima surpass the hind femora, at rest, the front of the male stridulatory apparatus is rounded but sharp apically. The cerci of the male are almost two times longer than the styli and the inner teeth are located within the basal one-third. ...
Morphological and genetic data allowed the authors to resurrect the name Tettigonia krugeri Massa, 1998 as a valid species. It is currently known only from two specimens (one male and one female) collected in Cirenaica (Libya).
... Despite the fact that several species of Green Bush-crickets are quite well known and have been the subject of detailed neuro-ethological studies (e.g., Zhantiev and Korsunovskaya 1978;Schul 1998), others remain poorly known from single specimens, and even nowadays, the discovery of new species continues (Ogawa 2003;Ichikawa et al. 2006;Chobanov et al. 2014;Storozhenko et al. 2015). Data on the systematics of this genus involve piecemeal morpho-acoustic studies conducted for geographically restricted areas or focused on morphological groups of species (e.g., Heller 1988;Rhee 2013;Chobanov et al. 2014). Our recent morphological and acoustic studies on Tettigonia, concentrated on the Western Palaearctic, revealed a number of conflicts within the published data when trying to identify certain populations and develop hypotheses about the systematics of the group (own unpublished data). ...
... Described from the Russian Far East, this subspecies was thought to differ in the length of the pronotum and tegmina from the nominotypical form from South Korea. However, many South Korean specimens are similar to T. uvarovi in their dimensions (Rhee 2013), and only the most long-winged ones are now assumed to represent T. dolichoptera (Storozhenko et al. 2015). In any case, this representative of the Eastern Palaearctic fauna may provide clues as to the relationships and phylogeographic connections of the east and west Palaearctic lineages of Tettigonia. 3. Poorly known sibling species termed here as follows: ...
... Clade B (Fig. 4) is formed by T. uvarovi (Fig. 5c, d), T. caudata (Fig. 5e), and the T. armeniaca complex (Fig. 5fi). T. uvarovi is a well-characterized species, morphologically resembling T. viridissima, with a song more similar to that of T. cantans (Rhee 2013). T. caudata is also a well-studied species, though this only applies to its nominotypical form, while its relationships with subspecific taxa are vague. ...
The genus Tettigonia includes 26 species distributed in the Palaearctic region. Though the Green Bush-crickets are widespread in Europe and common in a variety of habitats throughout the Palaearctic ecozone, the genus is still in need of scientific attention due to the presence of a multitude of poorly explored taxa. In the present study, we sought to clarify the evolutionary relationships of Green Bush-crickets and the composition of taxa occurring in the Western Palaearctic. Based on populations from 24 disjunct localities, the phylogeny of the group was estimated using sequences of the cytochrome oxidase subunit I (COI) and the internal transcribed spacers 1 and 2 (ITS1 and ITS2). Morphological and acoustic variation documented for the examined populations and taxa was interpreted in the context of phylogenetic relationships inferred from our genetic analyses. The trees generated in the present study supported the existence of three main lineages: “A”—composed of all sampled populations of Tettigonia viridissima and the Tettigonia vaucheriana complex, “B”—comprising Tettigonia caudata, Tettigonia uvarovi, and the Tettigonia armeniaca complex, and “C”—consisting of Tettigonia cantans. The present study provides the first phylogenetic foundation for reviewing the systematics of Tettigonia (currently classified mostly according to morphological characteristics), proposing seven new synonymies.
... Heller and D. Chobanov, unpublished data), as well as to the Eastern Palaearctic continental Tettigonia species with short wings, i.e. T. ussuriana Uvarov, 1939 (data on length of tegmina in Rhee, 2013). T. ussuriana has a song structure similar to that of T. cantans -a continuous trilling song, but with much lower syllable repetition rate than T. cantans (Zhantiev, 1981; Figure 4A), and thus clearly differs from all European species. ...
Tettigonia balcanica, sp. n., discovered in the mountainous regions of
the Central, Western and North Balkan Peninsula, is described in this
paper. This species has many similarities with T. silana and T. cantans.
However, it differs by the song and some morphological characters. Its
range differs from that of T. cantans, with which it has been confused so
far, but the border between their ranges has yet to be specified.
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.
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.
