The population dynamics of major cowpea pests was studied in northern Nigeria during 1992-95 in both the wet and dry seasons. Rainfall cowpea is grown as a subsistence crop, mixed at low densities with cereals. Dry-season cowpea is irrigated or grown on residual moisture in monocultures as a cash...

Cowpea yields are known to be low in most parts of the tropics because of heavy insect pest problems. In Africa, cowpea growers do not generally use synthetic insecticides; however, in most parts of Asia, dependence on the use of insecticides is common, often with serious environmental consequenc...
