α-Cyano-4-fluoro-3-phenoxybenzyl ester of monochlorinated pyrethric acid is a new kind of py-rethroids. Syntheses of the isomers of cis/trans-monochlorinated pyrethric acids and their esters were reported. The results of biological test indicated that these isomers of pyrethroids had insecticidal activities against Culex pipiens pallens (larvae). And some of the isomers, such as (αS,1R,3R)-cis-E-isomer 5aes and (αS,1R,3R)-cis-Z-isomer 5azs, exhibit higher insecticidal activities than deltamethrin.

Key words: monochlorinated pyrethriod, isomer, synthesis, pyrethroid, insecticidal activity
