Abstract Metofluthrin (commercial name SumiOne, Eminence ) is a novel pyrethroid insecticide developed by Sumitomo Chemical Co., Ltd. Metofluthrin has extremely high insecticidal activity to various pest insects, especially to mosquitoes. In addition, Metofluthrin has relatively high volatility and low mammalian toxicity. Metofluthrin is therefore suitable for use not only in conventional mosquito control formulations such as coils and liquid vaporizers, but also in a variety of novel devices that do not require heating, such as fan vaporizers and paper and resin emanators. Here we describe the insecticidal activity of Metofluthrin mainly against mosquitoes in various formulations in both laboratory and field trials. 

Metofluthrin (SumiOne 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl (EZ(E/ Z = 1/8))-(lR, 3/ )-2,2-dimethyl-3-(prop-l-enyl)cyclopropanecarboxylate, Fig. 1) is a novel pyrethroid insecticide discovered by Sumitomo Chemical Co., Ltd. [1], Metofluthrin was registered in more than 20 countries including Japan and USA and is currently under worldwide development for a variety of environmental health applications. 

Dimefluthrin [192] and metofluthrin [193] are two pyrethroid insecticides recently introduced by Sumitomo. In both dimefluthrin and metofluthrin, the vinylic chlorides of early pyrethroids have been replaced, in dimefluthrin by two methyl groups, and in metofluthrin by one methyl and one hydrogen group. They both share a 2,3,5,6-tetrafluorophenyl group, as in the pyrethroid tefluthrin.
