| 摘 要： | 甜菜夜蛾取食不同食料作物以后,对灭多威、辛硫磷和溴氰菊酯的敏感性均有不同程度的变化。解毒酶活性测定表明,不同食料对甜菜夜蛾3龄幼虫的多功能氧化酶(MFO)的脱甲基作用和羧酸酯酶(CarE)的活性有一定的诱导作用,和人工饲料相比,具有显著性差异。而羧酸酯酶动力学研究表明,几种食料作物对甜菜夜蛾羧酸酯酶底物亲和力(Km)的影响差异不显著。

| Abstract: | The susceptibility of the beet armyworm to methomyl,phoxim and deltamethrin, was various because of its feeding with different diets. Studies on detoxifying enzymes activities showed that the o demethylation of MFO and activity of CarE in the 3 rd instar larvae of spodoptera exigua,could be induced by different diets, and indicated that the K m value of CarE in the larvae reared on different diets were not distinctly different from that of the control. |
