A total of 20 new compounds containing the oxadiazolyl 3(2H)-pyridazinone moiety were synthesized. The structures of all the compounds were confirmed by 1H NMR, IR, MS, and elemental analysis. Their insect antifeedant activities against Asiatic corn borer Ostrinia furnacalis (Guenee) were examined and compared with commercial azadirachtin. The compounds exhibited significant levels of activity. The feeding deterrency values of IIIa,j were 57% and 51% at 500 mg/kg concentration, respectively.
