Abstract

Full-grown male and female pupae of black cut worm A. ipsilon were exposed to three doses of gamma irradiation 50, 100 and 150 Gy. Increasing the dose of irradiation applied to the parental male gradually reduced the egg hatch. The reduction was significant at all tested doses level when compared to the control treatment. The average number of eggs did not significantly different from untreated control at 50 and 100 Gy but it was significantly reduced at150 Gy. Also, the data indicated that the percentage of egg hatch was reduced gradually a t all tested mating combination of F I in comparison with their untreated control. Full-grown female pupae were exposed to three doses of gamma irradiation, the average number of eggs and percentage of egg hatch of treated female mated with normal male decreased. However, the data indicated that the percentage of egg hatch was increased at all tested mating combination of F 1 in comparison with their P I . The results lead to a conclusion that sterility could be inherited by irradiation of full grown male pupae more than irradiated full grown female pupae.
