用~(60)Coγ射线1、3、5、7、10 krad辐照4～5日龄的印度谷螟雄蛹,当辐照剂量为1～7krad时,被辐照蛹都能羽化,但10krad辐照的,羽化率仅40％。用1、3 krad辐照,成虫畸形率低,且对雄成虫交配能力影响较小,但用7、10 krad辐照,成虫畸形率分别为60％、100％,只有30％～50％的成虫能进行交配。1、3、5 Krad辐照雄蛹,F_1代卵孵化率分别比对照降低25.5％、21.1％、39.4％,F_2代卵的孵化率分别比对照降低56.6％、80.8％、74.0％。这可能是遗传不育现象。1、5、7 krad辐照的,诱导出了成虫翅透明的突变品系(透明型)。该突变品系对研究印度谷螟的部分遗传学及遗传防治有重要意义。
The pupal pups of Indocaladorapagi were exposed to ~ (60) Coγ-rays at 1, 3, 5, 7 and 10 krad for 4 ~ 5 days. The irradiated pupae could emerge at irradiation dose of 1 ~ 7krad, 10krad irradiation, the emergence rate of only 40%. At 1, 3 krad irradiation, the rate of adult deformity was low and the mating ability of adult male was negligible. However, with 7,10 krad irradiation, adult deformities were 60%, 100%, and only 30% to 50% Adults can mate. Hatch pupation at 1, 3 and 5 Krad decreased by 25.5%, 21.1% and 39.4%, respectively, compared with the control, and the hatchability of F_2 generation eggs was 56.6%, 80.8% and 74.0% lower than that of the control respectively. This may be the phenomenon of genetic infertility. Irradiated at 1,5,7 krad, a mutant strain of transparent adult wing was induced (clear type). The mutant strain is of great importance for studying the partial genetics and genetic control of Indian rice stem borer.
