摘　　要：分别用对应LC15、LC10和LC5浓度的茚虫威处理斜纹夜蛾3龄幼虫,探讨亚致死浓度茚虫威对斜纹夜蛾生长发育及解毒酶活性的影响。结果表明:与对照相比,茚虫威处理后斜纹夜蛾化蛹率、羽化率和孵化率均明显下降,且经LC15浓度处理后成虫寿命以及单雌产卵量皆显著低于对照,说明亚致死浓度茚虫威对斜纹夜蛾当代和下一代的种群增长有一定的抑制作用。亚致死浓度茚虫威处理斜纹夜蛾3龄幼虫后,斜纹夜蛾酯酶和谷胱甘肽S-转移酶以及多功能氧化酶O-脱甲基活性与对照相比无显著差异,说明亚致死浓度茚虫威对这3种解毒酶活性影响不大。Based on the bioassay results,3rd instar larvae of Spodoptera litura were treated with indoxacarb at concentrations corresponding to LC15,LC10 and LC5 by artificial diet dipping methods.Lower pupation rate,emergence rate and egg hatchability were observed when compared with control,and adult longevity and eggs laid per female decreased significantly when exposed to indoxacarb at LC15 concentrations.These results indicated that indoxacarb at sublethal concentrations had a negative effect on population develo...
