Synthesis and antifeedant activity of new oxadiazolyl 3(2H)-pyridazinones
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.
Synthesis and insecticidal activity of neonicotinoids derivatives
A new class of compounds- neonicotinoids containing oxadiazole -were synthesized and characterized by using 1H NMR, IR, MS and Elemental Analysis. Their insecticidal activities were tested against Mythimna separata Walker and Aphis rumicis Linnaeus, some of them showed some insecticidal activity.
