| 摘 要： | 目的]茚虫威是一种新型二嗪类杀虫剂,作用机制独特,探讨了斜纹夜蛾对茚虫威的抗性风险和抗性机理。方法]采用饲料浸毒法对斜纹夜蛾敏感种群3龄幼虫经过13代11次抗性选育,测定斜纹夜蛾对茚虫威的抗性倍数及抗性机理。结果]斜纹夜蛾对茚虫威的抗性倍数达到69.6倍。测定选育抗性种群3龄幼虫羧酸酯酶、谷胱甘肽S-转移酶和多功能氧化酶活性结果表明:选育种群羧酸酯酶活性和多功能氧化酶O-脱甲基活性分别是选育前的3.7倍和2.5倍,差异显著;谷胱甘肽S-转移酶为选育前的1.1倍,差异不显著。结论]斜纹夜蛾对茚虫威的抗药性与羧酸酯酶和多功能氧化酶活性有关,与谷胱甘肽S-转移酶无关。

| Abstract: | Aims]Indoxacarb is a novel insecticide belonging to the oxadiazine class with unique action mechanism,excellent insecticidal activity against Spodoptera litura and low toxicity to no target organisms,it is therefore an ideal candidate to substitute organophosphate and pyrethroid insecticides.the resistance risk and resistance mechanism of this pest to indoxacarb wsa discussed.Methods] Artificial diet dipping method was used to test the risk and resistamce mechanism of spodeptera litura to indoxacarb with ... |
