Untreated females of Drosophila melanogaster Meigen mated with males exposed to 4 kr of gamma radiation in the larval, and 16 kr in the pupal or adult stage deposited the normal number of eggs, none of which hatched. Females irradiated in the pupal or adult stage with 8 or 16 kr and mated with untreated males produced few or no eggs. Females irradiated in the larval stage produced fewer eggs after exposure to high doses of gamma radiation than untreated females but showed no reduction in the percentage of emerging adults. The longevity of males or females exposed in the pupal or adult stage was not affected by the radiation treatment. Males and females irradiated in the larval stage were shorter lived than untreated insects. Untreated female flies mated with irradiated males (16 kr) produced sterile eggs, but when mated a second time with untreated males, produced viable eggs. Untreated female flies mated with normal males produced viable eggs, hut when subsequently mated with irradiated males, they continued to produce viable eggs. Sterile males confined with normal males and females reduced the number of progeny.
