| 摘 要： | 采用9MeV X-射线辐照处理云杉小墨天牛45、龄幼虫和雌虫,结果表明,辐照能明显影响其发育和繁殖能力,导致幼虫期延长,幼虫不能化蛹或羽化1,00%阻止幼虫化蛹和羽化的最低吸收剂量分别为45～60Gy、35～40Gy;阻止田间雌虫繁殖F1代幼虫的不育剂量为140Gy,雌雄两性成虫同时辐照的不育剂量小于60Gy。为此,可分别采用60Gy和140Gy处理原木及木质包装中云杉小墨天牛幼虫和成虫,以防止其扩散和传播。

| Abstract: | In laboratory tests,the 4th and 5th instar larvae and adults of pine sawyer beetle,Monochamus sutor Linnaeus,was irradiated by 9MeV X-rays,the result shows that there is significant effect on its development and propagation.The irradiation elongated lifespan of irradiated larvae,and prevented its pupation and eclosion.The minimal absorbed dose for 100% preventing pupation and eclosion is 45~60Gy and 35~40Gy,respectively.The sterile dose for female collected in the field is 140Gy,but it was decreasing to 60G... |
