| 摘 要： | 本文报道了棉铃虫经辐照诱导的不育效应。用60 Co γ射线处理棉铃虫蛹,成虫的羽化率随着剂量的升高而降低,畸形率和死蛹率增加。不同时期辐照蛹对成虫羽化率有明显影响。棉铃虫辐射不育以采用羽化前2d 的老熟蛹辐照为好,其羽化率为86-54 % 。卵的不育率随剂量的升高而升高。根据F1 代辐射遗传不育效应的研究认为:棉铃虫当代亚不育剂量以300 Gy 为宜。

| Abstract: | The irradition\|induced sterile effect of Heliothis armigera was studied.It showed that after the pupa of cotton bollworm were treated with 60 Co γ\|ray,the emerging rate of adult insects decreased with increasing of dosage,and the deformity rate and the dead pupa rate increased with increasing of dosage,too.The emerging rate of adult insects was affected obviously when the pupae were irradiated in the different stages.When the matured pupae were irradiated in 2 days before emerging,the emerging rate of 86\^54% was obtained.The sterile rate of eggs increased with increasing of dosage.According to the study on the effect of sterile inheritance of F\-1 treated with radiation,the suitable sub\|sterile dosage for cotton bollworm was 300Gy. |
