Virus diseases cause substantial yield reduction in cowpea ( Vigna unguiculata (L.) Walp) production in West and Central Africa. Improved cowpea cultivars have been developed and distributed to various national programs but these cultivars were tested only against local virus isolates. To identif...

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...

Population dynamics and migration of cowpea pests in northern Nigeria: implications for integrated pest management
Cowpea is an important grain legume throughout the tropics and subtropics, covering Asia, Africa, and Central and South America, as well as parts of southern Europe and the United States of America. The use patterns, seed preferences, and cropping systems vary from region to region. Insect pests,...
The use of cowpea haulms as fodder is attractive in mixed crop/livestock systems where both grain and fodder can be obtained from the same crop. Traditional farming systems which use the haulms as fodder in Asia, Australia, Africa, and other regions are reviewed. ILRI and I1TA have undertaken joi...
