| 摘 要： | 在室内研究了甲氧虫酰肼对斜纹夜蛾的亚致死效应。结果表明，亚致死剂量甲氧虫酰肼能抑制斜纹夜蛾幼虫的生长发育，显著降低产卵量和孵化率。此外，研究还发现，亚致死剂量甲氧虫酰肼对斜纹夜蛾酯酶、多功能氧化酶和谷胱甘肽S-转移酶具有一定的诱导作用。与对照相比，LC10剂量甲氧虫酰肼处理斜纹夜蛾24 h后以及LC30剂量处理48 h和96 h后，酯酶活性显著提高；LC10剂量处理24 h后，多功能氧化酶活性显著提高；LC30剂量处理96 h后，谷胱甘肽S 转移酶活性显著提高。

| Abstract: | Methoxyfenozide(RH-2485) belongs to a new group of insect growth regulators,bisacylhydrazines,which mimic natural insect moulting hormone by binding competitively to ecdysteroid receptors and inducing a premature larval moult.Although acute toxicity tests have shown that methoxyfenozide is the most potent non-steroidal ecdysone agonist to date against larval Lepidoptera,and exhibits a high degree of safety to non-target insects,knowledge about the sublethal effects of methoxyfenozide is still limited.Consid... |
