摘 要 ：分别用含０．０１％的芸香甙，槲皮素２－十三烷酮的人工饲料连续饲养棉铃虫Ｈｅｌｉ－ｃｏｖｅｒｐａａｒｍｉｇｅｒａＨｕｂｎｅｒ１～７代，测定不同处理的棉铃虫种各谷胱甘肽Ｓ－转移酶（ＧＳＴ）和乙酰胆碱酯酶（ＡＣｈＥ）的活性变化以及幼虫对杀虫剂的反应，以单独人工饲料养的各种作对照，芸香甙Ｆ１代对甲基硫磷的耐药性提高３倍，槲皮素Ｆ１，Ｆ２代和２－十三烷酮Ｆ１代对甲基对硫磷的耐药性有所提高，对灭多威和溴氰菊酯

Abstract:Effects of plant allelochemicals on glutathione-S-transferase (GST) and acetylcholinesterase (AChE) activities were studied with midgut or head homogenates of larvae in Helicoverpa armigera Hubner that had reared on an artificial diet containing 0. 01% of
