摘　　要：ZJ3265{(E+Z)-2-[2-(4-氰基苯)-1-(3-三氟甲基苯)亚乙基]-N-(4-二氟甲氧基苯)联氨酰胺}是由浙江省化工研究院有限公司自主开发的缩氨基脲类新型杀虫剂。采用浸渍法测定了ZJ3265对粘虫Mythimna separata、小菜蛾Plutella xylostella和斜纹夜蛾Prodenia litura的室内杀虫毒力。结果表明,ZJ3265对粘虫、小菜蛾和斜纹夜蛾的LC50值分别为1.37(1.16～1.62)、18.53(15.13～22.10)和15.40(11.98～18.85)mg/L。在田间用24%ZJ3265悬浮剂处理3 d(有效剂量120 g/hm2),其对小菜蛾、斜纹夜蛾、甜菜夜蛾Spodoptera exigua和菜青虫Pieris rapae的防效分别达74.9%、76.7%、70.3%和84.4%;在试验剂量下,未观察到对作物产生药害。ZJ3265{（E＋Z）-2-[2-（4-cyanophenyl）-1-[3-（trifluoromethyl）phenyl]ethylidene]-N-[4-（difluoromethoxy）phenyl]hydrazinecarboxamide} is a novel insecticide in China.Toxicity of ZJ3265 against Mythimna separata,Plutella xylostella and Prodenia litura was tested in the laboratory by leaf-dipping method,and the field efficacy of ZJ3265 in controlling P.xylostella,P.litura,Spodoptera exigua and Pieris rapae was evaluated.The results showed that the LC50 values of ZJ3265 against M.separata,P.xylostella and P.litura were 1.37（1.16-1.62）,18.53（15.13-22.10） and 15.40（11.98-18.85） mg/L,respectively.The control efficacy of ZJ3265（240 SC）against P.xylostella,P.litura,S.exigua and P.rapae was 74.9%,76.7%,70.3% and 84.4%,respectively,three days after the treatment of ZJ3265 at 120 g a.i./ha.No crop injury was observed at the dosage of the tests.
