摘　　要：通过生物测定和离体酶活性测定 ,研究了取食棉花、玉米、高粱、大豆等寄主植物的棉铃虫对高效氯氰菊酯敏感性及体内酶活力的变化。结果表明 ,寄主植物对棉铃虫体内羧酸酯酶、谷胱甘肽S-转移酶等解毒酶和乙酰胆碱酯酶的活性具有显著影响 。The sensitivity to betacypermethrin and relevant enzymic activitie s of the cotton bollworm (Helicoverpa armigera) feeding on different host plants were tested with bioassay and biochemical methods.The results indi cated that host plants may not only change the sensitivity of the bollworm to this insecticide,but also significantly influence the activity of carboxylest erase,glutathione s-transferases and acetylcholinesterase in Helicoverp a armigera.
