Abstract
Eggs of potato tuberworm (0 to 64hr) were irradiated with doses ranging from 1 to 5 Krad. For a given dose, the radiosensitivity of eggs decreased with increase in age and the decrease was larger with dose of 3 Krad and above. When pupae of different ages were irradiated with dose of 20, 25 and 30 Krad, adult emergence increased with age at irradiation and decreased at higher doses. Irradiation of eggs and pupae to obtain competitive sterile adult male was not feasible. Adult irradiation was found most ideal and near complete sterility (96.3 per cent) was induced when freshly emerged males were irradiated with a dose of 45 Krad. Induced sterility was the result of induction of dominant lethal mutation in the sperm and was permanent. (author). 4 tabs., 14 refs., 4 figs.
