摘　　要：用303、5与40Gy三个剂量的60Coγ射线辐照松褐天牛,结果表明辐照对松褐天牛的生育力有一定影响,其中以40Gy辐照剂量影响最为显著。通过保持雌虫不变,更换雄虫,发现雌虫与经辐照的雄虫交尾后再与非辐照雄虫交尾,雌虫的产卵量以及孵化率虽较更换雄虫前略有提高,但明显低于对照。说明辐照对松褐天牛的生殖系统有一定的影响。不同的配比模式之间产卵量和孵化率也存在显著差异。The fertility of the Japanese pine sawyer beetle Monochamus alternatus （Coleoptera： Cerambycidae） irradiated with ^60Coγ-rays was remarkable reduced at the doses of 30Gy, 35Gy and 40Gy, especially at 40Gy. When the non-irradiated females were coupled with the irradiated males first, and then coupled with non-irradiated males, the hatchability and the fertility had little higher but lower than the control. It explained that radiation has certain influence to the female gonad. It also has difference between the hatching rate and the amount of eggs in different match.
