The genera of seed-beetles (Coleoptera, Bruchidae)
... They are best known for the economic consequences of their ability to destroy seed crops and stored seeds, causing tens of millions of dollars in damage annually to crop legumes (Kingsolver 2004), an increasingly important global protein source particularly in developing and emerging economies (Henchion et al. 2017). Species are distributed on all continents (except Antarctica) and are placed into 65 currently recognized genera (Anton 2024;Borowiec 1987). ...
... The most recent treatment of the world genera is from Borowiec (1987) and the internal classification implemented in that treatment is derived from that of Bridwell (1932Bridwell ( , 1946. Traditionally, seed beetles were treated as the chrysomeloid family Bruchidae and that classification scheme reflected this placement. ...
... Recent advances in chrysomeloid systematics have provided overwhelming evidence from both comparative morphology and molecular systematics that the seed beetles are nested within Chrysomelidae, are sister to the subfamily Sagrinae, and should therefore be treated as the subfamily Bruchinae (Crowson 1960;Lawrence and Britton 1994;Mann and Crowson 1981;McKenna et al. 2019;Reid 1995;Zhang et al. 2018). In light of this, we here use a modification of the classification from Borowiec (1987) that implements a reduction in rank such that subfamilies become tribes and tribes become subtribes. Borowiec (1987) postulated a classification scheme based on an interpretation of derived and ancestral characters without explicit analysis of a character matrix. ...
... These beetles attack and damage seeds and pods of some edible, medicinal, and ornamental legumes and wild forest plants (Arora 1980). Their larvae develop mainly in leguminous plant seeds and less often feed on representatives of the plant families Apiaceae and Asteraceae (Borowiec 1987). Other species of the genus are used as biological control agents against some invasive plant species (Derbel et al. 2007, LÓPEZ-NÚÑEZ et al. 2020. ...
... The species were identified using the keys of Bouček (1965), Graham (1969Graham ( , 1991, Kalina (1981), Borowiec (1985Borowiec ( , 1987, Decelle (1989), Rasplus (1989), Bouček & Rasplus (1991), Zerova & Seryogina (1994), Zerova (1995), Gibson & Fusu (2016) and Fusu (2017). ...
The seed-eater wasp Bruchophagus astragali Fedoseeva, 1954, seed beetle Bruchidius marginalis (Fa-bricius, 1775) and а great diversity of associated parasitoid wasps were reared from fruits of liquorice milkvetch Astragalus glycyphyllos L. (Fabaceae) in Bulgaria. The following species of Chalcidoidea were identified: Baryscapus endemus (Walker) and Pediobius bruchicida (Rondani) (Eulophidae); Anastatus sp., Eupelmus confusus Al khatib, E. barai Fusu, E. messene Walker and E. vesicularis (Retzius) (Eu-pelmidae) and Dinarmus acutus (Thomson), Pteromalus sequester Walker and Pteromalus sp. cf semo-tus (Walker) (Pteromalidae). New associations with both seed-feeding species and also with liquorice milkvetch were found for many of the reared parasitoids.
... The taxonomic elaboration of European Bruchinae by the major taxonomic works (Hoffmann 1945;Lukianovich and Ter-Minasian;1957;Borowiec 1987;Anton 2001Anton , 2010 yielded ca. 160 species (not including stored product pests); however, new species and species combinations are still being described (e.g., Delobel and Delobel 2007). ...
... Presumed host plant relations and distribution of Bruchinae species in European legumes have been initially mostly based on the collection of adults in the vegetation and by subsequent taxonomic identification (Hoffman 1945;Zacher 1952;de Luca 1967;Anton 2010;Borowiec 1987;Borowiec and Anton 1993, and others). However, some of these studies (e.g., Hoffman 1945) do provide host plant associations based on rearing. ...
The paper investigates the distributions of legumes (Fabaceae) and their associated seed beetle species (Bruchinae) across vegetation zones and regions of Europe and evaluates the host range and specialization of seed beetles. 1584 legume species/subspecies/varieties were included in the study and ca. 16% of these serve as known hosts by the 175 seed beetle species found in Europe. Both plant and seed beetle species richness increased from the Boreal to Mediterranean zones/regions. 717 legume species occurred only in single zones/regions and only 4.7% of these (34 species) were hosts for 38 bruchine species specific to a zone/region. Europe has 664 native legume species and 381 of these are Eu-endemics. There were 52 alien legume species found. Similarities in plant species composition by the Sørensen index were pronounced between the Central-European and the Mediterranean, between the Transcaucasian and Mediterranean, and between the Colchis-Caucasian and the Pontic-Caspian areas. The most species-rich genus is Astragalus L. with 334 species and 16 subspecies. Of the two major pre-dispersal seed predator genera, Bruchidius Schilsky species are sensu lato oligophagous, using a wide range of leguminous tribes as hosts, but restricted to few host species within a tribe. In contrast, members of the Bruchus L. genus are sensu stricto oligophagous species and, despite being constrained to the Fabeae tribe, most of them feed on several Lathyrus L. and Vicia L. species. The ways annual and perennial life cycles as well as chemical constituents of legumes might affect the colonization success of the seed beetles are discussed.
... These two factors result in consistently low yields, forcing the local markets to import legumes from Cameroon and consequently increase their prices. Post-harvest losses (fruit weight loss, reduced nutritional value, and impeded germination capacity) are mainly caused by small Coleoptera belonging to the Chrysomelidae family (Borowiec 1987;Delobel 2000; Keneni et al. 2011) . The most economically damaging genera are Acanthoscelides, Bruchidius, Bruchus, Callosobruchus, Caryedon, and Zabrotes (Johnson 1981, Huignard et al. 2011) . ...
... For decades, morphospecies have been identi ed exclusively using morphological diagnostics provided by taxonomic studies (Borowiec 1987) . ...
The seed beetles of the family Chrysomelidae, subfamily Bruchinae, are pest species that cause substantial damage to legume crops, affecting supply for human and animal consumption. Legumes are a staple of the Congolese population due to their protein-rich seeds, productivity, and ability to improve soil fertility when combined with cereals. In this study, we focused on bruchids that attack two varieties of peas, Cajanus cajan and Vigna unguiculata subsp. cylindrica , in the Republic of Congo. 80 individuals of bruchids were considered from the two main pea-growing departments: Bouenza and Niari. Specimens were collected using baited traps placed in the field and by manually selecting affected seeds from the storage areas. Individuals were categorised at the species level based on morphological traits and molecular barcode analyses. This is the second time that 12S rRNA sequences of bruchids from the Republic of Congo have been deposited in the GenBank database. This study emphasises the need to enrich the GenBank database with DNA sequences originating from areas where the technical means to carry out quality morphological analyses are limited.
... Bruchinae is the largest group of insects that engage in this feeding behavior, which happens in almost all species of the subfamily [3]. Today, the subfamily comprises almost 1750 species, with 1650 [4] and approximately 100 assigned to 65 genera worldwide [5,6]. ...
In order to replace chemical herbicides, which harm the environment and health, we seek sustainable methods to control weeds. We remove a seed-beetle species, Acanthoscelides atrocephalus, from synonymy with Acanthoscelides modestus and recognize it as a potential bioagent for Aeschynomene denticulata and A. indica. Belonging the megacornis group of the genus Acanthoscelides, its fine morphology was analyzed using high-resolution photography and scanning electron microscopy. The species differs from others of the A. megacornis group based on integument coloration, distinctive patterns of vestiture on the pronotum and pygidium, large and sexually dimorphic eyes, a strong frontal carina extending from the vertex of the head to the clypeus, and distinctive armature in the internal sac of the male genitalia. It stands out as a biological control agent due to the larvae’s habit of feeding on seeds, which hinders the development of the embryo. Through tetrazolium and germination tests, it was discovered that 100% of the infested seeds had no viable seed integument and did not germinate. A. atrocephalus is no longer a synonym of Acanthoscelides modestus. This species is a predator of A. denticulata and A. indica and prevents seed germination, becoming promising as a bioagent for the control of these weeds.
... Other researchers worth mentioning who have significantly contributed to our understanding of Brazilian bruchines are the American Clarence Dan Johnson and the Argentinian Arturo Luis Teràn . Bruchines are one of the few chrysomelid subfamilies with a published world catalog (Udayagiri and Wadhi 1989), an overview of world genera (Borowiec 1987), as well as a complex treatment of the Nearctic fauna (Kingsolver 2004), and a subject of a book chapter (Ribeiro-Costa and Almeida 2012). Aspects of the natural history of Brazilian species have been recently investigated by Linzmeier et al. (2004), Sari and Ribeiro-Costa (2005) ...
The leaf beetles (Chrysomelidae) are one of the most species-rich family of herbivorous beetles with about 45,000 species worldwide. Based on the contributions of chrysomelidologists to the Taxonomic Catalog of the Brazilian Fauna - CTFB, the family comprises 6,079 species in 562 genera of which 951 species are endemic to Brazil, standing out as the most diverse, representing 4.8% of the Brazilian fauna and 17.1% of the beetle species. Chrysomelidae has twelve subfamilies with nine reported to Brazil: Galerucinae, the richest with 1,916 species in 202 genera, followed by Cassidinae, Eumolpinae, Cryptocephalinae, Chrysomelinae, Bruchinae, Criocerinae, Lamprosomatinae and Sagrinae - this with only one species. Most of these subfamilies need urgent revision, since many species are poorly characterized, and polymorphism is frequent in some groups. The Czech couple Jan and Bohumila Bechyně were the researchers who described most species from Brazil. Furthermore, despite the increase of research on biology, natural history, host plants, genetics, ecology from 1980’s much still need to be investigated to better known the Brazilian Chrysomelidae and probably many new species are yet to be discovered.

... It is an important pest of several pulses including cowpea, chickpea, pigeon pea, pea, soybean, lentils, haricot beans and damaged pulses lose weight and market value and they are generally unacceptable for human consumption (Javaid and Poswal, 1995). However, 20 species of pulse beetle to be part of six genera, which are mentioned as cosmopolitan pests of stored legumes (Borowiec, 1987;Southgate, 1979) of the genera Vigna, Phaseolus, Glycine, Lablab, Vicia, Pisum, Cicer, Lens, Arachis, Cajanus (Credland, 1987;Erler et al, 2009;Tuda et al, 2011). In the storage, condition pulse beetles coexist to survive on dried germplasm of leguminous plants (Rodriguez, 2018). ...
In tropical and subtropical countries of the world, Callosobruchus maculatus (F.) is a crucial pest of pulses. After the harvest, pulse beetles in storage cause qualitative and quantitative worsening of legumes. Survival of different geographical strains of cowpea weevil may vary on different host legumes. The research was conducted to examine screening for ovipositional preference, growth and development of cowpea weevil, on nine common legume hosts, viz., cowpea, green gram, pigeon pea, pea, desi chickpea, kabuli chickpea, black gram, soybean and red lentils. In the present study, life phases of Lucknow strain (variant) of C. maculatus, was seen on nine stored pulses at laboratory condition for the assessment of growth and development and better management in storage. The outcome of present studies, indicated that the cowpea weevil favour cowpea, green gram, pigeon pea, pea, for its highest oviposition because the highest number of eggs was found on these legumes followed by desi chickpea, kabuli chickpea while on black gram, soybean and red lentils lowest number of eggs were observed. The developmental time of cowpea weevil was short on cowpea, green gram, pigeon pea, pea, followed by desi chickpea, kabuli chickpea, while the longest developmental period was on the black gram, soybean and red lentils. The percent adult emergence, percent weight loss and growth index was highest in cowpea, green gram, pigeon pea and garden pea, desi chickpea, and kabuli chickpea whereas lowest percent of adult emergence, weight loss and growth index was found in black gram, soybean and lentil after three generations. From this research it was clear that cowpea, green gram, pigeon pea, pea, desi chickpea, kabuli chickpea was most preferred host legumes among all nine examined stored legumes, whereas black gram, soybean, and red lentils were least preferable hosts to the Lucknow strain of C. maculatus.

We identify 94 species of New World Bruchinae (Coleoptera: Chrysomelidae) that have not been revised since original publications that predate the establishment of current bruchine genera. Many of these have appeared in catalogs or checklists and have been transferred to genera without inspection of primary type specimens. We were able to inspect the primary types of 77 of these species; we provide new combinations for 38 and confirm previous combinations made in catalogs for an addition 39. We provide emended names for four taxa and designate a neotype for Bruchus atrosignatus Pic, 1935. Type specimens could not be located for 14 of the additional 17 species, with only three species of known deposition not yet inspected. These 17 species should be considered as species incertae sedis and included as such in any catalogs or checklists until types are examined by future reviewers.
