Beanweevil (Callosobruchus maculatus) was reared and allowed to damage cowpea severely, while the heavily infested cowpea was then processed into flour. The nutritional composition of heavily infested cowpea flour and Callosobruchus maculatus were investigated using Association of Official Analytical Chemists (AOAC). The result showed that, infested cowpea flour has; 15.50% of Protein, 226 µg/100g of Vitamin A, 17.39 mg/100g of Vitamin C, 1.67 mg/100gof Vitamin B, as for Minerals; 200 mg/Kg of Calcium, 650 mg/100g of Phosphorus, 528 mg/100g of Iron and 110 mg/Kg of Magnesium. It was concluded that, there was high depreciation in the nutritional composition of infested cowpea when compared to non-infested cowpea, which was due to the weevil infestation.
