The bean weevils or seed beetles are a subfamily (Bruchinae) of beetles, now placed in the family Chrysomelidae, though they have historically been treated as a separate family. They are granivores, and typically infest various kinds of seeds or beans, living most of their lives inside a single seed. The subfamily includes about 1,650 species ...
Insects are active when temperature reaches 20 °C; temperatures above 25 °C are very favorable to their activity in the field whereas colder temperatures below 15 °C and wet weather limit insect mobility. Once fertilized, females B. rufimanus lay eggs on developing pods of faba beans. Rain, wind and temperatures below 20 °C put on hold the ...
The parasitoid wasp Pediobius foveolatus can be used as augmentative biological control against the Mexican bean beetle. [3] Systemic insecticides are commonly used at planting where Mexican bean beetle is a frequent pest. Some of these insecticides do not persist in the plant long enough to protect the plant from early generations.
Many authors prefer to call them seed-beetles or bean beetles, because they are not true weevils, and because in most species, the larvae develop inside seeds, particularly beans. [ 3 ] [ 4 ] Because Bruchinae was known as the family Bruchidae until the 1990s, [ 1 ] they are sometimes still called bruchid beetles.
The black bean aphid is a major pest of sugar beet, bean, and celery crops, with large numbers of aphids cause stunting of the plants. Beans suffer damage to flowers and pods which may not develop properly. Early-sown crops may avoid significant damage if they have already flowered before the number of aphids builds up in the spring. [9]

Jumping beans, each about 7 to 10 mm The "trap door" of the jumping bean on the left has been removed, and the one on the right remains attached, next to two moth larvae and their pupal casings. Mexican jumping beans ( Spanish : frijoles saltarines ) are seed pods that have been inhabited by the larva of a small moth ( Cydia saltitans ) and are ...
