A laboratory experiment of a completely randomised design and replicated four times was carried out to evaluate the effectiveness to control Callosobruchus maculatus in cowpea by the synthetic insecticide Actellic dust, and by several natural protectants - ash, coconut oil, powdered cloves and black pepper. The data collected included the number of damaged and undamaged seeds, weight of damaged and undamaged seeds and the number of live and dead bruchids. Seeds treated with Actellic dust and black pepper powder had significantly low percentages of damaged seeds. Black pepper powder and coconut oil showed good potential in protecting cowpea against bruchid damage.
