Sterilization of the Melon Fly, Dacus cucurbitae COQUILLETT (Diptera : Tephritida), with Gamma-Radiation : Fertility of FX₁ Progeny of Flies Treated with Sub-Sterilizing Doses

Abstract

Whether or not the semi-sterility of the melon fly, induced by irradiation with doses of 3 or 5 kR two days before adult emergence, could be transmitted to the FX₁ progeny was studied using the change in fecundity of the progeny. There was no detectable inherited sterility of FX₁ generation of melon flies treated with sub-sterilizing doses. No significant differences in fecundity among FX₁ progeny from crosses of untreated and treated flies were observed.
