Dimefluthrin: A new pyrethroid insecticide agent
A series of 4-substituted-2,3,5,6-tetrafluorolbenzyl (1R,3R)-chrysanthemates were synthesized and evaluated for their insecticidal activity against Culex pipiens pallens (Coquillett). Among them, the 2,3,5,6-tetrafluoro-4- methoxymethyl analogue (dimefluthrin) exhibited the highest insecticidal activity, and also showed a faster knockdown efficacy towards Cx. pipiens pallens and the southern house mosquito (Culex quinquefasciatus Say) than d-allethrin in a mosquito coil formulation.
