In order to find novel diacylhydrazine derivatives which possessed high activities against pests, 20 novel N-(tert-butyl)-N'-fluorobenzoyl-substitutedpyridylcarbonyl hydrazide derivatives were synthesized by introducing fluoro-contained phenyl and pyridine into the basic structure of diacylhydrazines. Their structures were confirmed by 1H NMR, 13C NMR, IR and HRMS. The bioassay results indicated that most of the compounds exhibited more than 80% mortality against Mythimna separateat the concentration of 500 mg/L. Among these compounds, N-(tert-butyl)-N'-(2,6-difluorobenzoyl)-N-2-chloronico-tinohydrazine (6bb)andN-(tert-butyl)-N'-(2,6-difluorobenzoyl)-N-2,5-dichloronicotinohydrazine (6gb)exhibited 100% and 80% mortality against Mythimna separateat 10 mg/L, respectively. The LC50 of compound 6bb against Mythimna separatawas 8.77 mg/L, and it showed about 0.51 times of toxicity against Mythimna separatethan tebufenozide and had 1.5 times of toxicity against Plutella xylostella than tebufenozide.
