Inherited effects in F₁ progeny of partially sterile male Phthorimaea operculella (Lepidoptera: Gelechiidae)
Journal of Economic Entomology 90 (5), 1097-1101
Abstract: 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.
