用~(60)Coγ射线0(对照),10、20、30、40、50kR,辐射4、6、8、10日龄桃小食心虫蛹,8—10日龄(羽化前1—8天)是辐射的适宜时期。30、40kR 辐射8—10日龄蛹,对成虫的交尾能力没有明显影响,并具有相当高的不育效应,是辐射蛹的适宜照射量。50kR 辐射8—10日龄蛹,在雄虫中诱发的卵不育率为97.8%,在雌虫中诱发了完全不育,但成虫的交尾率显著低于对照。雌虫对辐射更敏感。
8 ~ 10 days old (1-8 days before eclosion) were irradiated with ~ (60) Coγ ray 0 (control), 10,20,30,40,50 kR, and 4, 6, Is the appropriate period of radiation. 30,40kR 8-10 day-old pupal radiation, no significant impact on the mating ability of adults, and has a very high effect of infertility, radiation pupation appropriate dose. 50kR irradiated 8-10 day-old pupal, inducing ovum infertility rate of 97.8% in male, inducing complete infertility in female, but the male’s mating rate was significantly lower than the control. Female insects are more sensitive to radiation.
