Cowpea, [Vigna unguiculata (L.) Walp.] also known as blackeye pea, southern pea and lobia is one of the most important food legumes in the semi-arid tropics. With an average of 25% protein (on dry weight basis) in its seeds and tender leaves, cowpea is a major source of protein. In storage, Callosobruchus maculatus F. also called cowpea beetle, cowpea weevil or bruchid, is regarded as the most important and common pest of cowpea both in Africa and Asia. All vigna crops except rice bean are susceptible to bruchids.
