The toxicities and anti-feedant activities of thirteen asymmetrical 1,3,4-oxadiazoles containing a 2H-pyridazin-3-one group were investigated. The compounds were shown to possess considerable activity in retarding the development of larvae of a number of Lepidoptera, but they were all inactive against Homoptera, Diptera and Acarina. The compounds had powerful anti-feedant activity comparable with that of azadirachtin. The toxic symptoms of the poisoned larvae indicated that the compounds were novel insect growth regulators with a mode of action that might be similar to the chitin-synthesis inhibition of oxadiazole compounds and/or the juvenile hormone effect of pyridazinone compounds.

Eight 2-(5-(trifluorometlayl)pyridyloxymetbyl) 1,3,4 oxadiazoles have been designed and synthesized by fore- step synthetic route. The structures of all new compomlds were confirmed by 1H NMR, mass and HR mass spectroscopy. The pr eliminary bioassay tests show tlaat some compounds, especially those having fluorine on the benzene ring (114 mid IIs), exhibited a siglfificmlt insecticidal activity on manywoml, Leucania separata Walker, at 500mg 1.

Five fluorine-containing 4,4-dihydroxylmethyl-2-aryliminooxazolidines and five 4,4-dihydroxylmethyl-2-aryliminothiazolidines were synthesized and evaluated for their inhibitory activity against trehalase in vitro. All these compounds were very readily synthesized compared with the natural trehalase inhibitors. They had moderate inhibitory activity toward trehalase, and showed larvicidal activity and inhibition action to insect flight. The steric parameters and semiempirical quantum parameters of these compounds were acquired by using the molecular modeling method and the PM3-SCF-MO method, respectively. A quantitative structure-activity relationship between halfinhibitory concentrations toward trehalase and the above parameters was established.

Fourteen new 2,5-disubstituted-1,3,4-oxadiazoles, namely (i) six 2-[2,2-dimethyl-3-(2,2-dichlorovinyl)-cyclopropyl]-5-substituted-1,3,4-oxadiazoles and (ii) eight 2-substituted-phenoxymethyl-5-substitutedaryl-1,3,4-oxadiazoles, were synthesized and evaluated for their insect growth regulatory activity against second-instar larvae of armyworm (Pseudaletia separata Walker). Two of these compounds (7 and 8) showed good insecticidal activities, with LC50 values of 14.33 and 15.85

Several possible three-dimensional conformations of substituted dibenzoyl-1-tert-butylhydrazine (SBH) were established with the help of a molecular modeling method. It was found that there was a good parabolic relationship between larvicidal activity (pLD50 or pLD50-1) and the nearest distance r of the oxygen atomic center of carbonyl group A to the atomic center connecting with benzene ring B of substituents in conformation I of SBH. Molecular mechanics calculations revealed that SBH and 20-hydroxyecdysone have several similarities in the
