The present work was directed to study the ovicidal, larvicidal and antifeeding effects of cartap against S. littoralis. The sterility action on adult moths was also considered. Cartap showed a drastic influence on embryonic development of treated eggs. The older eggs were more susceptible to this insecticide than the younger ones. However, the tested concentrations had a slight larvicidal activity in this respect. The higher the concentration the higher was the rate of larval starvation. The percentage of pupation was slightly decreased as a result of larval treatment with cartap. A negative correlation between the different concentrations of cartap on the fecundity of female moths was recorded. However, cartap at all tested rates showed no harmed effect on the hatchability of eggs which were deposited by females treated in larval stage.
