The influence of leaf powders of Vitex grandifolia and Dracaena arborea incorporated into maize and cowpea flour on the survival of maize weevil (Sitophilus zeamais) and cowpea weevil (Callosobruchus maculatus), respectively was tested. Survival of adult beetles of maize and cowpea weevil was least on cowpea (10 g) and maize (10 g) flour treated with 3 g V. grandifolia (3.30–20%, 6.70–20%, respectively) and 3 g D. arborea (3.30–13.3%, 0.0–3.3%, respectively) compared to other treatments, which… CONTINUE READING
