摘　　要：研究了60Coγ射线对松材中松墨天牛(Monochamns altevnatusHope)老龄幼虫辐射检疫效应。结果表明,辐照对松墨天牛幼虫的化蛹、羽化能力造成明显影响。当吸收剂量达到400Gy时开始出现畸形蛹,450Gy5、00Gy时,试虫最终化蛹率低于10%,而在450Gy未发生羽化。500Gy、21d后松墨天牛幼虫死亡率高达90%以上。试验表明松墨天牛幼虫死亡率与辐照处理之间符合剂量效应关系。Effects of gamma irradiaton on Monochamns altevnatus Hope larvae were studied. The results showed that mortality of Monochamns altevnatus Hope on the 21st day reached over 90% by a dose of 500Gy treatment. The pupating rate decreased below 10% with the dose higher than 400Gy, while the abnormal pupae began to appear at this dose, and there are no eclosion at 450Gy. The relationship between death rate and absorbed dose could be described by dose-response curve for tested pest.
