Susceptibility of processed and stored cassava, plantain, yam, and cocoyam to coffee bean weevil ( De Geer).

Background: Coffee bean weevil ( DeGeer) (Coleoptera: Anthribidae) infestation is a major challenge affecting processed, dried, and stored foods globally. However, the growth performance of this insect pest in processed and stored cassava, plantain, yam, and cocoyam is poorly understood. Resolving this will guide future biotechnological efforts on these food products.

Entomotoxicity of some agro-wastes against cowpea bruchid, (Fab.) [Coleoptera: Chrysomelidae] infesting cowpea seeds in storage.

Cowpea, is a popular agricultural produce known as poor man's meat among Africans because it is very cheap and affordable. In spite of its importance, its infestation by cowpea seed bruchid, has been a major constrain hindering its storage. Considering the high level of infestation of cowpea by and the high level of pollution caused by agricultural products, this research investigated the entomotoxicant effectiveness of rice husk, wheat husk and groundnut pod ash and powder in the control of cowpea beetle in storage.
