Metofluthrin: Novel Pyrethroid Insecticide and Innovative Mosquito Control Agent

摘要

16.1 Introduction Metofluthrin (SumiOne?, Eminence?) is a novel pyrethroid discovered by Sumitomo Chemical Co., Ltd. (Figure 1). It was registered in Japan in January 2005 and is under worldwide development for environmental health use. Metofluthrin has extremely high knockdown activity against various insect pests especially mosquitoes as well as high volatility and low mammalian toxicity. This chemistry is applicable to not only existing mosquito-controlling devices such as mosquito mats and coils, but also to various new formulations and devices such as paper emanators, fan-driven devices, and resin formulations. Metofluthrin is more than 40 times as active as d-allethrin against southern house mosquitoes (Culex quinquefasciatus) when used in mosquito coils. This paper describes the story behind the discovery of metofluthrin and this compound's efficacy against mosquitoes in various formulations.
