bioassays indicated that some of these title compounds exhibited excellent insecticidal and acaricidal activities. The insecticidal activities against oriental armyworm of compounds IVa, IVd, IVe, IVf, IVg, IVi, IVk, and IVp were equal to commercialized Chlorfenapyr, and the insecticidal activities of most of compounds IVb, IVc, IVd, IVf, IVg, IVj, IVk, IVl, IVs, IVt, IVu, IVw, IVx, IVz, and Chlorfenapyr
合成了一系列新型的含酯基的2-芳基-吡咯衍生物,并通过(1)NMR和元素分析对其结构进行了表征。评估了这些新化合物对东方粘虫,蚊子,小菜蛾,绿色稻飞虱和豆蚜的杀虫活性以及对红蜘蛛的杀螨活性。生物测定的结果表明,其中一些标题化合物表现出优异的杀虫和杀螨活性。化合物IVa,IVd,IVe,IVf,IVg,IVi,IVk和IVp对东方粘虫的杀虫活性等同于商品化的氯芬吡,而大多数化合物IVb,IVc,IVd,IVf,IVg,IVj, IVk,IVl,IVs,IVt,IVu,IVw,IVx,IVz和氯芬那比以0.10 mg kg(-1)的蚊子抵抗蚊子的比率为100%,化合物IVd,IVe,IVf,IVg,IVh,IVi和IVk的杀螨活性等于或优于氯苯那吡。特别是,结果表明,[4-溴-2-(4-氯苯基)-3-氰基-5-(三氟甲基)吡咯-1-基] 3-甲基丁酸甲酯(IVg)对红蜘蛛的杀螨活性为2.65。从LC
