Abstract: Preparations of new pyrethroid esters(5, 6) containing a pyridine ring in the acid moiety were described. The α and β form of α cyano 3 phenoxybenzyl esters 6 were separated chromato graphically. These compounds were screened for insecticidal activities against Mythimna separata(W.) and Aphis fabae and for miticidal activity against Tetranychus urticae. Compound 5 showed 85% mortality against Mythimna separata(W.) at 250 mg/L, and 6 β had more miticidal activity on Tetranychus urticae than fenvalerate at a mass fraction of 200 mg/L.

Key words: Pyrethroid, Pyridine, Insecticidal/acaricidal activities
