Abstract
Full grown pupae of the black cut worm, agrotis ipsilon were irradiated with 5, 10, 15, 30 and 35 krad of gamma radiation for males and with 5, 10, 15, 20 and 25 krad for females. The emerged adults were paired with the untreated opposite sex. Both the percentage of mated females and the average number of spermatophores per mated female decreased by irradiating male pupae with 20 krad and above. percentage of inseminated mated females decreased at the dose 15 krad and the reduction increased with increasing the gamma dose. Fecundity of female paired with irradiated male was decreased gradually with increasing the dose. A severe reduction in fecundity was obtained, in the case of irradiated female pupae. Egg hatch was also dose dependent, as it decreased with the increase in the radiation dose. Females were more radiosensitive than males, as far as reduction in hatchability was concerned. The sterilizing doses ranged between 30-35 and 15-20 krad for males and females, respectively.
