利用核辐射带电粒子如质子、电子或不带电粒子如X射线、γ射线、中子,在一定辐照剂量范围内处理害虫,均能导致不育,或者发生遗传变异,或者死亡。人们就利用昆虫的这些生理效应来防治害虫。 一、基本理原 用适宜剂量辐照昆虫,可以引起蛋白质及核蛋白质分子水平上的改变,抑制核糖核酸和脱氧核糖核酸的代谢,同时,射线还可以引起生殖细胞中染色体易位,使受辐照的昆虫部分不育,而这种不育可以遗传到下一代(F_1),使F_1代更不育,这种辐照剂量称为半不育剂量。高于 The use of irradiated nuclear particles such as protons, electrons or uncharged particles such as X-rays, gamma rays, and neutrons, to treat pests within a range of radiation doses can lead to infertility, or genetic variation, or death. People use these physiological effects of insects to control pests. First, the basic principles of the appropriate dose of radiation with the appropriate insects, can cause changes in protein and nuclear protein molecular level, inhibition of RNA and DNA metabolism, while the rays can also cause chromosomal translocation in germ cells, Part of the insects according to infertility, and this infertility can be inherited to the next generation (F_1), F_1 ​​generation more sterile, this radiation dose known as the semi-infertility dose.
