Bean weevils
Common weevils found in beans are the cowpea weevil, Callosobruchus maculatus; broad bean
weevil, Bruchus rufimanus; and the bean weevil, Acanthoscelides obtectus. Adult weevils
found in beans are relatively small beetles, 0.13 - 0.2 inch in length, somewhat teardrop or triangular
in shape, and dull-colored with white, reddish, or black markings.
Life cycle
Damage
Damage may occur in the garden or in storage. Weevil larvae feed within the bean pod and consume
nearly the entire bean contents.
Solutions
Be sure seeds are free of weevils before planting. Remove and destroy bean plants immediately after
harvest. Treatment with insecticides is not recommended.
