摘要
研究了γ射线辐照处理对野生和实验室饲养的光肩星天牛雄虫的繁殖生物学特征和田间纱笼释放交尾竞争能力的影响。结果表明,110Gy辐照处理的野生和实验室饲养的雄虫与野生雌虫交尾后所产卵的孵化率分别平均降低到3.4%和0;野生和试验室饲养雄虫适宜的辐照剂量率分别为1.75Gy/min和1.40Gy/min;在释放比为5∶1的田间纱笼实验条件下,能有效降低卵的孵化率。
The effect of γ-rays radiation on their fecundity and mating competitiveness of the wild and insectary-reared males of Anoplophora glabripennis was studied in laboratory and in field cage. The results show that, the hatchability was 3.4 % when the patrilateral-parent was the irradiated wild long horn beetle of 110Gy and the hatchability even came to 0 when the parent was the treated reared one by the dose irradiation. The optimum dose rate for the reared and wild long horn beetle males was 1.40 Gy/min and 1.75 Gy/min, respectively. When the ratio of treated male to wild ones was 5 ： 1, the hatch rate was effectively decreased.
