| 摘 要： | 使用9MeV高能X射线对松墨天牛的老熟幼虫、蛹和成虫辐照处理的结果表明,辐照能明显影响其生长发育及繁殖能力。导致幼虫发育迟缓,幼虫期延长。对于老熟幼虫,100%阻止化蛹和出现成虫的剂量为50Gy,经机率值分析,死亡率达到99.9968%的检疫辐照剂量为61.4Gy(55.5～72.6);对于9日龄以下蛹,100%阻止繁殖F1代幼虫的不育剂量为120Gy。辐照也导致雌虫和雄虫的存活时间缩短,100%阻止11日龄以下雌虫和雄虫的不育剂量为140Gy。由此说明,辐照耐受性随发育的完善而增强。建议使用60～80Gy作为松墨天牛幼虫的检疫辐照剂量,140Gy作为蛹和初期成虫的检疫辐照剂量,用于原木和木质包装的检疫处理。

| Abstract: | The mature larvae,pupae and adults of Pine Sawyer,Monochamus alternatus Hope,were irradiated separately by 9MeV X-rays in laboratory tests;as a result,the development and propagation of the irradiated insects were significantly effected.The life span of irradiated larvae elongate significantly,and the minimal absorbed dose for 100% preventing pupation and eclosion of the mature larvae is 50Gy,and the dose for 99.9968% mortality is 61.4Gy through probit analysis.The dose for 100% preventing propagation of 9 ... |
