摘　　要：[目的]通过茚虫威结构衍生化研究,以期开发出具有自主知识产权的二嗪类杀虫剂新品种。[方法]以黏虫、小菜蛾、斜纹夜蛾为供试靶标,通过室内生物活性测定,发现化合物SIOC-Y-047较其他改造物表现出更好的室内杀虫活性,进一步完成SIOC-Y-047对3种鳞翅目害虫的毒力曲线测定及作用特性评价。[结果]SIOC-Y-047对3个靶标的LC50值分别为1.34、14.05、9.43 mg/L,活性略低于对照药剂茚虫威。室内作用特性与茚虫威相似,以胃毒和触杀作用为主,无根内吸活性。[结论]SIOC-Y-047对鳞翅目害虫黏虫、小菜蛾和斜纹夜蛾均表现良好的室内杀虫活性,活性略低于对照药剂茚虫威。[Aims] This paper aims to study the indoxacarb derivatives to find a novel oxadiazine pesticide. [Methods] Based on our indoor pesticide bioassay, SIOC-Y-047 had better insecticidal activity against Lepidoptera than other indoxacarb derivatives, with the targets of Mythima separata, Plutella xyllostella and Prodenia litura. [Results] Via the virulence and performence property test, the medium lethal concentration （LC50） of SIOC-Y-047 was 1.34, 14.05 and 9.43 mg/L against the three targets respectively. And, the main performance property of SIOC-Y-047 was the same as indoxacarb, mainly with stomach toxicity and contact toxicity, no systemic action by root. [Conclusions] SIOC- Y-047 is less active than indoxacarb against Lepidoptera.
