This study was conducted to find out the toxic effect of the southern cowpea weevil Callosobruchus maculatus stages when its food was treated with alcoholic extracts of Punica granatum peels. The study showed that the lowest percentage of hatching was 61.26% in the treatment of chickpea seeds with a concentration of 15% of P. granatum peel extract. The treatments had a clear effect on the harmful larval stage , and the highest significant percentage of death was 81.4% in cowpea seeds treated with a concentration of 25%, and all results were significantly different from the control treatment. the mortality rate significantly increased in the pupa stage, and it increased treatment significantly to 46.66% in the concentration of 25%, compared to the, control which amounted to 0%. To find out the effect of the extracts used in the study on the first generation individuals, the egg retention coefficient was calculated.
