Encyclopedia entry (1928–1936)
BRUCHUS (Larius), a beetle of the family Bruchidae; its larvae live in seeds, mainly of leguminous plants. B. pisi L. - the pea weevil (4.5 mm in length); the beetles fly in early summer, laying eggs on young pea pods; the hatched larvae bore into the grains where they undergo further development. The larvae remain even in harvested peas. Here they pupate. The beetle that emerges from the pupa remains in the pea until spring, when it bores a hole in the pea and leaves it. Peas severely infested with the weevil are little suitable for food. Measures against the weevil see Warehouse pests.
