噻虫酰胺对5种鳞翅目昆虫的杀虫活性研究

噻虫酰胺,试验代号JS9117,是江苏省农药研究所股份有限公司于2009年创制发现的新型邻杂环苯甲酰胺类化合物。以氯虫苯甲酰胺为对照药剂,采用浸叶碟饲喂法、浸虫法及综合法等处理小菜蛾、甜菜夜蛾、斜纹夜蛾、棉铃虫、二化螟等幼虫,研究了噻虫酰胺的杀虫活性。结果表明,噻虫酰胺对5种鳞翅目昆虫具有高活性,对小菜蛾的活性是氯虫苯甲酰胺的1.58～1.83倍,对甜菜夜蛾是0.64～4.87倍,对斜纹夜蛾是1.04～1.34倍,对棉铃虫是1.36～1.98倍,对二化螟是0.23～1.33倍。本研究为噻虫酰胺的进一步研发和应用提供了参考。

Research on Insecticidal Activity of JS 9117 Against Five Kinds of Lepidoptera

The novel compound,JS 9117,was discovered by Jiangsu Pesticide Research Institute Company Ltd. in 2009. In order to clarify insecticidal activity of JS 9117,five insects were treated on three ways comparing with chlorantraniliprole. These insects were Diamondback moth Plutella xylostella （L.）],Beet armyworm （Laphygma exigua Hubner）,tobacco caterpillar Prodenia litura （Fabricius）],striped rice borer （Chilo suppressalis） and corn earworm （Helicoverpa armigera Hubner）. The treated ways were dipping leaf,dipping larva,and dipping leaf and larva. Result showed that JS 9117 had excellent insecticidal activity. The relatively toxicity ratio of JS 9117 to Chlorantraniliprole is 1.58-1.83 against Diamondback moth,0.64-4.87 against Beet armyworm,1.04-1.34 against tobacco caterpillar,1.36-1.98 against corn earworm,and 0.23-1.33 against striped rice borer. This research was useful to JS 9117＇s R D and application.
