Abstract:Irradiation of 24-h-old adults of Ephestia cautella (Walker) did not significantly decrease the mating ability of males or females at doses up to 45 krad. Irradiated females had a tendency to mate more often and to contain more spermatophores than control females. The number of adult progeny per fertile pair decreased from 101 at 5 krad to 1 at 35 krad when males were irradiated and from 74 at 5 krad to <1 at 30 krad when females were irradiated. The dose required to sterilize 50% of both sexes was ca. 30 krad, and the doses for 99% sterility were ca. 50 and 60 krad for females and males, respectively. All effects of the treatment were more severe when both sexes were irradiated and then paired. The decreased number of progeny per fertile pair plus the increased percentage of sterile pairs produced severe decreases in reproductive capacity. The production of sterile adults at doses that did not reduce mating ability or longevity indicates that application of the sterile-insect release technique for population suppression of this species is feasible.
