4-thiadiazole-containing pyrazole oximes was designed and synthesized. Their acaricidal and insecticidal activities were evaluated. Bioassay results indicated that some target compounds exhibited good acaricidal and insecticidal properties. Especially, compound 8m had 80% acaricidal activity against Tetranychus cinnabarinus at the concentration of 50 μg/mL, compound 8f displayed 100% insecticidal activities against
设计并合成了一个新的含1,3,4-噻二唑的吡唑肟库。他们的杀螨和杀虫活性进行了评估。生物测定结果表明,某些目标化合物具有良好的杀螨和杀虫特性。尤其是,化合物8m在浓度为50μg/ mL时对朱砂叶螨有80%的杀螨活性,化合物8f在浓度为50μg/ mL时对蟹蚜有100%的杀虫活性,化合物8r和8w对蚜虫有100%的杀虫活性。小菜蛾的浓度为50μg/ mL。此外,化合物8r(LC50 = 19.61微克/毫升)和8瓦特(LC 50 = 9.78微克/毫升)具有可比较的或甚至更好的杀虫活性比对照Pyridalyl(LC 50 = 17.40微克/毫升)对小菜蛾。
