Three substerilizing doses 50, 100 and 150 Gy of gamma radiation were tested against full – grown male and female pupae or against full-grown male or female pupae of Agrotis ipsilon. The results showed that fecundity of irradiated females crossed with irradiated males was decreased by increasing irradiation dose. The decrease in egg – hatchability % and increase in sterility % induced by gamma radiation were found to be positively correlated with the dose level. The parentage of larval and pupal mortality increased significantly (p ≤ 0.05) with the increase of used doses. In addition, larval and pupal durations were found to be significantly prolonged as a result of gamma- irradiation treatment. In general, the results obtained indicated that the biological action of gamma irradiation against A. ipsilon larvae was more remarkable when both crossed females and males were irradiated followed by irradiated females crossed with non-irradiated males. |
