摘要: 通过研究γ射线辐照处理对朱砂叶螨生长发育的影响,为朱砂叶螨的γ射线辐照检疫处理提供依据。以95~1 650 Gyγ不同剂量辐照朱砂叶螨的卵、若螨、雌成螨,发现γ射线辐照处理在3 d内不能直接杀死若螨和雌成螨,但能影响叶螨的生长发育。330 Gyγ射线辐照处理若螨和成螨,产的卵不能孵化,330 Gyγ射线辐照朱砂叶螨卵,卵不能孵化。试验结果表明,330 Gyγ射线辐照朱砂叶螨能使其完全不育,阻断其繁衍进程,330 Gy可以作为朱砂叶螨的辐照检疫处理的最低剂量。

Abstract: The effect of gamma irradiation on the growth and development of Tetranychus cinnabarinus was studied and a series of gamma radiation doses ranging from 95 to 1 650 Gy were treated on the eggs, nymphs and female adults. The results showed irradiation doses between 250 and 1 650 Gy could obviously affect the growth and development of their eggs, nymphs and female adults. A treatment of 330 Gy irradiation prevented eggs from hatching. Although an irradiation dose of 330 Gy could not directly kill nymphs and female adults within 3 days, it could make nymphs and female adult completely infertile and prevent their reproduction. An irradiation rate of 330 Gy is suggested as the minimum dose (Dmin) for phytosanitary measure.
