    新型杀虫剂氯氟氰虫酰胺对不同鳞翅目害虫的毒力和田间防效

    Bioactivity and field efficacy of novel insecticide ZJ4042 against different lepidopterous pests

    • 摘要: 氯氟氰虫酰胺(ZJ4042)3-氯-N1-(2-甲基-4-七氟异丙基苯基)-N2-(1-甲基-1-氰基乙基)邻苯二甲酰胺是由浙江省化工研究院有限公司自主开发的邻苯二甲酰胺类新型杀虫剂。采用浸渍法测定了氯氟氰虫酰胺对小菜蛾Plutella xylostella、甜菜夜蛾Spodoptera exigua、斜纹夜蛾Prodenia litura和二化螟Chilo suppressalis的室内杀虫毒力,并进行了田间药效试验。结果表明:氯氟氰虫酰胺对小菜蛾、甜菜夜蛾、斜纹夜蛾和二化螟的LC50值分别为0.046、0.072、0.071和1.95 mg/L,与氟虫双酰胺和氯虫苯甲酰胺的杀虫毒力相当。在田间用20%氯氟氰虫酰胺悬浮剂处理(有效剂量30 g/hm2),对小菜蛾、斜纹夜蛾、甜菜夜蛾及菜青虫Pieris rapae药后7 d的防效为90.1%~96.3%;对二化螟和稻纵卷叶螟Cnaphalocrocis medinalis药后15 d的防效为82.9%~90.5%;在试验剂量下,未观察到其对作物产生药害。

       

      Abstract: ZJ40423-chloro-N2-1-methyl-1-cyano-ethyl-N1-4-(1,2,2,2-tetrafluoro-1-trifluoromethyl-ethyl)-phenyl-phthalamide is a novel insecticide developed by Zhejiang Research Institute of Chemical Industry,Ltd,China.Toxicity of the ZJ4042 against Plutella xylostella,Spodoptera exigua,Prodenia litura and Chilo suppressalis were tested in the laboratory by leaf-dipping method,and the field efficacy of ZJ4042 in controlling P.xylostella,S.exigua,P.litura,Pieris rapae,C.suppressalis and Cnaphalocrocis medinalis was evaluated.The LC50 values of the chemical to these four insects were 0.046,0.072,0.071 and 1.95 mg/L,respectively,which were almost equivalent to that of flubendiamide and chlorantraniliprole.The control efficacy of Z4042 (200 SC) against P.xylostella,S.exigua,P.litura and P.rapae seven days after treatment,and C.suppressalis and C.medinalis fifteen days after treatment,were 90.1%-96.3% and 82.9%-90.5%,respectively,at the dosage of 30 g a.i/hm2.No crop injury was observed at the dosage of the tests.
