The cowpea weevil, Callosobruchus maculatus (F.) and the rice weevil, Sitphilus oryzae (L.) are destructive insects attacking cowpea seeds and rice grains causing weight loss and reduced nutrition values. Laboratory experiments were conducted to evaluate the insecticidal toxicity of three plant oils and powders of anise (Pimpinella anisum), Bitter orange (Citrus aurantium) and Sweet marjoram (Origanum majorana ) as grain protectants on the mortality of C. maculatus and S. oryzae. The results… CONTINUE READING
