The investigation of the African mahogany (Khayagrandifoliola) c.d.c gum extract was evaluated for the control of beans weevil (Callosobruchusmaculatus) on stored cowpea. 5ml of 20,000; 40,000; 60,000 and 80,000ppm of aqueous were used per 100g of cowpea. The increase in concentration caused increase in mortality which suppressed oviposition and emergence of F1 progeny, it does not inhibit germination and seed coat is not affected. The result is indicative of the potential of Khayagrandifoliola for the control of Callosobruchus maculates on stored cowpea.
