Callosobruchus maculatus (Fabricius, 1775) - (cowpea weevil)
The beetle is an important pest of stored cowpeas and other legumes in tropical and subtropical countries. It is occasionally introduced into temperate regions with infested seeds. Once introduced through trade or from the field, it rapidly multiplies in legume stores, causing substantial losses. After hatching, the larvae bore into dry seed and several larvae can develop in one seed. Control is done through fumigation. Several plant products have been also shown to be effective.
The development from egg to adult lasts 1-2 months under suitable conditions. The adult is about 3 mm long, reddish or light-brown with a variable pattern of dark marks. Often, there are 4 darker marks on the elytra and in females 2 more on the exposed apical end of the abdomen.
