美国佐治亚沿海平原试验站的昆虫学家们提出一种新的害虫防治法——部分绝育。他们用r射线照射怍物害虫的雄虫,使其部分不孕,然后把它们释放,去和野生的雌虫进行交配。这些受r射线处理过的雄虫由于染色体受到破坏,交配时把受到的遗传损害传递给后代。在三、四代之后,绝大多数 Entomologists at the Georgia Coastal Plains Experimental Station have proposed a new pest control law - partial sterilization. They irradiated rodents with male pests of insect pests, partially infertile them, and released them to mate with wild females. These r-treated males pass on their genetic damage to their offspring as their chromosomes are destroyed. After three or four generations, the vast majority
