摘要：利用60Co-γ射线对胭脂虫孕卵期进行辐射试验,探讨60Co对胭脂虫生物学特征的影响。结果表明,高剂量(3000rad以上)辐射胭脂虫造成其子代性比严重失调,雄虫几乎为0,无法进行有性生殖,导致无法产生后代,高剂量辐射对雄虫的损伤极大。低剂量辐射(特别是500rad)下F1较对照:各龄级虫口数提高;成虫期雌虫数明显高于对照,雄虫数略高;孵化量、孵化率提高;单株雌成虫鲜重、干重均明显增重;怀卵量大幅增多;雌成虫个体鲜干重、鲜干比、体积无差异。对于500rad辐射的胭脂虫,F2在有效生殖率、鲜干重和鲜干比方面效果较F1还好,存在优势显效滞后现象。但连续培育3代后,与对照已无差异。
To discuss the effect of 60^ Co-γ ray on the biological characteristics of cochineal, the pregnant cochineal were radiated by five doses of 60^ Co in this radiation experiment. The results showed that： the high doses （above 3000rad） of 60^ Co led to the unbalanced sex ratio of new generation, and the number of males was nearly zero, and sexual reproduction was impossible. At last, offspring couldn＇ t be produced. Also, the males of new generation were hurt by the high doses. On low doses （especially 500md）, as compared to CK, there were much increase in F1 in the following items： 1 ） population number in each age; 2） the number of adult females and males; 3） amount of incubation and hatching rate; 4） fresh weight and dry weight of adult females on per plant host; 5） the number of brooding eggs. However, it was indiscriminate to fresh weight and dry weight of an adult female, fresh / dry ratio, and the volume of an adult female. To 500rad, F2 was better than F1 on effective reproductive rate, fresh weight and dry weight, and fresh / dry ratio on adult female. This illustrated there were obvious hysteresis in some ways, but after three generations, there were no significant influence compared with control in progeny.
