Paper emanator, metofluthrin

Fig. 8 Field efficacy of Metofluthrin paper emanator against night biting indoor mosquitoes 0Culex quinquefasciatus) in Malaysia...

In a house on Lombok Island in Indonesia, a paper emanator impregnated with 200 mg of Metofluthrin exhibited repellent effects of 80% or greater against C. quinquefasciatus and Anopheles mosquitoes over a period of 4 weeks [6]. In addition, in outdoor conditions on Lombok Island, it exhibited superior repellent effects against C. quinquefasciatus as well as Anopheles balabaciensis and An. sundaicus, which are vector mosquitoes for malaria [7]. 

A similar paper emanator impregnated with 200 mg of Metofluthrin exhibited almost complete repellent activity against A. albopictus in Japan [3]. 

From these results, we were able to confirm that Metofluthrin paper emanator had sufficient effects against various species of mosquitoes under practical conditions. 

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.
