Almond Moth: gamma radiation effects on the life stages

Effects of 6 gamma radiation dosages from 5 to 100 krad on all metamorphic stages of Cadra cautella (Walker) were studied. Development of adults from treated eggs and larvae was prevented by 30 and 20 krad, respectively. Some adults emerged from treated pupae at all levels except 100 krad, but radiation greatly reduced their lifespan. Irradiated adults paired with untreated adults paired fewer eggs than pairs of unirradiated adults, and these eggs had reduced hatch and developmental success. Females were sterilized by 30 had and males by 100 Krad. Progeny of irradiated adults inherited genetic damage that affected their reproductive ability.
