Diacylhydrazine compounds have been widely used as one of the most important insect growth regulators. In order to find novel diacylhydrazine insecticide lead compounds with high activity and low toxicity, a series of novel nitrogen heterocyclic analogues of diacylhydrazine derivatives were designed and synthesized by introduction of 1-[(6-chloropyrid-3-yl)methyl]-5-methyl-1H-1,2,3-triazol-4-yl moiety to the diacylhydrazine molecule skeleton. Their structures of the target compounds 3 were characterized by IR, ¹H NMR, ESI-MS techniques and elemental analyses. The results of bioassays showed that some of the title compounds 3 possessed moderate insecticidal activities against Spodoptera exigua and Plutella xylostella larvaes in the concentration of 200 mg/L. Whereas all the title compounds 3 displayed weak insecticidal activity against Aphis in the same concentration.
