  Bruchus is a genus of seed beetles in the leaf beetle family Chrysomelidae, comprising approximately 36 species. The genus is characterized by distinctive male genitalia morphology, including a large, sclerotized, boomerang-shaped ventral plate used in species identification. Members are specialized herbivores feeding almost exclusively on legumes in the tribe Fabeae (Vicieae), including peas, lentils, and vetches. Several species are significant agricultural pests, notably B. lentis on lentils, B. pisorum on peas, and B. rufimanus on fava beans. The genus is primarily Palearctic in distribution, with some species introduced to North America, Africa, and Australia.
