Abstract
Fresh adults and pupae of different ages were exposed to different doses of Gamma radiations for induction of
sterility. Fresh and one-day to three-day old adults and two-day to four-day old pupae treated with 2000 and 2500
rads produced cent per cent sterile males and females, respectively. The exposure of freshly formed adults to a dose
of 5000 rads produced 100% sterile females but maximum of 96.9% senile males were produced with a dose of 6000
rads,
