研究了γ射线对棉铃虫当代及其F 1代繁殖的影响、辐照导致棉铃虫F 1代的染色体畸变和对F 1代雄虫有核精子束的影响。说明棉铃虫的辐照适期为蛹末期 ,辐射遗传不育 (F 1代不育 )的适宜剂量为 2 0 0Gy(剂量率为 3 2 3Gy min)
The effects of γ-rays on the generation and generation of F 1 generation of cotton bollworm (Helicoverpa armigera) were investigated. Chromosome aberration (F 1) and nuclear sperm bundle (F 1) were detected. The conclusion is that the suitable period of irradiation of cotton bollworm is the last stage of pupal period, and the suitable dose of genic male sterile (F 1 generation sterile) is 200 Gy (the dose rate is 3 2 3Gy min)
