In search of new N-heterocyclic compounds possessing good biological activities, 17 novel pyrazole oxime derivatives were designed and synthesized by introducing benzotriazole moiety into pyrazole oxime skeleton based on fenpyroximate. Their structures were tested by 1 H NMR, 13 C NMR and elemental analysis. Preliminary bioassay data displayed that 3 compounds showed 70%～100% insecticidal activities towards Tetranychus cinnabarinus at 20 μg/mL. 6 compounds possessed 90%～100% mortality rates towards Aphis medicaginis at 20 μg/mL. Moreover, 16 compounds displayed more than 80% insecticidal activities against Mythimna separata (Walker) at 500 μg/mL.
