The results of the recent study revealed that the biological effect ofsub-lethal concentration of some insecticides were varied on houseflyeggs and pupae. The results mentioned a higher effect ofNemec-super inincreasing the average incubation period and redaction of the averageeggs hating percentage egg percentage which reached 20.8 hour 70.1%respectively . The Cyromazine average period of larval stage 11.2 , 10.4days respectively and the average percentage of abnonnal larvaeproduced 4.5 , 5.0% respectively from treated eggs . The effect of eggstreatment expand to the average period of pupal stage and to thepercentage of adult eclosion from the pupae , average period of adultstage and on reducing the number of eggs I female .Pupal treatmentshowed a little variation on average pupal period and percentage of adulteclosion from the pupae , adult period and number of eggs /female .
