Initial average body weight was ( 1 2 9 . 7 1 gram for males and 136.73 gram for females). Birds were housed in metallic battery in such away that,each group equipped 15 cages with two females and one rnnle, 4.n aeebch cmge birds w e r e Ted ad. lib. on basal diet contain (22% crude protein and 2850 ME cal/kg) . The first group was given the basal diet polluted with methoprene on a dose of 50 ppm. The second group was given the basal diet polluted with fenitrothion on a dose of 6.5 ppm. these doses are equivalent to LC,, of these insecticides for T. castaneum and T. confuseum. The third group served as control and was given the basal diet sprayed with the solvents applied in the first and second group. Feeding treatments lasted for 12 weeks.
