The effect of gamma radiation administered to newly emerged adults of Dacus cucumis French on sterility and competitiveness was evaluated. A dose of 11 krad caused almost complete sterility in males while females given 6 krad were totally sterile, through infecundity. Sterilized males showed reduced competitiveness. In competitive mating tests a dose of 7 krad gave the lowest egg hatch and this hatch was significantly lower than that given by 9 and 11 krad. In a paired comparison mating test, 7 and 9 krad treated males mated significantly less frequently than untreated males, but the ability of 6 krad treated males was unimpaired.
