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]
Insecticides are the primary management strategies for bean leaf beetle infestation. [7] Foliar insecticides, or insecticides applied directly to leaves as opposed to soil, are typically used. Insecticide strategy is modified when bean pod mottle virus is suspected. In this strategy, two sprays are done of pyrethroid insecticides. The first is ...
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 ...
American naturalist Thomas Say described the bean weevil species as Bruchus obtectus in 1831, [1] and was later moved to the genus Acanthoscelides. [4] In a 1870 publication John Lawrence LeConte mistakenly called it Bruchus obsoletus, which led several later author to call it under this name which in fact belonged to another species, and as a result references to A. obtectus in publications ...
Adults emerge from dormancy in late spring, and each female lays several hundred eggs in clusters of 50 to 75 on bean plant leaves. [citation needed] The larvae are voracious feeders, and can inflict heavy damage on a field of bean plants during an infestation. After a few weeks of feeding, the larvae pupate in groups under the leaves. They ...
1833), commonly known as the Mexican bean weevil, is one of the main pests of the common bean (Phaseolus vulgaris) that affect seeds during storage (Morales et al., 2018). Weevils lay the eggs on the seed coat and then larvae feed and grow inside, which results in serious affectations including hollow grains with reduced nutritional quality and ...
