Chino. 分别用质量浓度为0．41、0．82、1．23、1．64和2．05g／L的草甘膦处理空心莲子草叶甲Agasicles hygrophila的卵、幼虫、蛹及成虫，并以清水为空白对照，测定卵的孵化率、历期，幼虫和成虫的成活率、历期．结果表明：各处理组叶甲卵的孵化率与对照的差异不显著；处理组叶甲幼虫和成虫的成活率与对照的差异显著，对照组的幼虫成活率和成虫成活率分别是草甘膦2．05g／L时的1．59倍和1．31倍．[著者文摘]

The treatment mass concentrations of glyphosate for eggs, larvae, pupae and adults were 0.41,0.82, 1.23, 1.64 and 2.05 g/L, respectively. There was no difference in the hatching rate of eggs between the glyphosate treatment and the control group with the concen- trations of glyphosate. However, the survival rates of larvae and adults treated by glyphosate were significantly lower than those in the control group. The survival rates of larvae and adults in the control group were 1.59- and1. 31-fold of that in the treated group with 2.05 g/L glyphosate, respectively.[著者文摘]
