Adult male Phthorimaea operculella (Zeller), were exposed to substerilizing doses of gamma irradiation: 100, 150, and 200 Gy. Inherited effects in the F1 progeny of irradiated male parents were examined. Mean developmental time and the percentage mortality of the F1, progeny, at each examined dose, were higher than that of the control group. Moreover, the sex ratio of the F1 progeny was skewed in favor of the males. Mean longevity, fecundity, and the percentage fertility of the F1 progeny were lower than those of their parents and the control group. Mating ability and the frequency of mating of F1 adults were similar to those of their partially sterile male parents and the control. The genetic basis of the F1 characteristics has been discussed. The use of substerilizing doses of irradiation could be considered as an important component in a potato tuber moth-control strategy.
