Males of Ephestia elutella (Hübner), substerilized with 15 krad of gamma irradiation, were released at ratios of 4:1 and 9:1 to untreated males into a simulated empty warehouse. The mating competitiveness of irradiated males was 91 to 93% as good as that of the untreated males, and the percentage of hatched eggs was reduced accordingly. In trials where irradiated males and untreated males were released, the majority (55.8 to 73.5%) of the F1 progeny was offspring of the irradiated males and inherited sufficient genetic damage to be sterile when intermated. These results suggest that populations of the tobacco moth within tobacco storages might be greatly reduced or eliminated by the release of a high ratio of substerilized males.
