Metofluthrin is a newly developed highly effective pyrethroid which has excellent insecticidal activity against mosquitoes. Due to its superior characteristics, Metofluthrin is suitable for use in various types of mosquito control formulation, including mosquito coils and liquid vaporizers. Metofluthrin also has excellent... 

We carried out a detailed investigation into the performance of metofluthrin in mosquito coils and liquid vaporizers, the most commonly used forms of heated mosquito control devices. 

Southern house mosquito [Culex quinquefasciatus) is widely distributed in tropical and subtropical areas worldwide and the most important target for mosquito coils. Mosquito coils containing 0.005% metofluthrin exhibited an efficacy exceeding that of coils containing 0.2% d-allethrin against this species (laboratory strain), and the relative efficacy is estimated to exceed 40 times that of d-allethrin (Figure 7).

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.

To determine the practical effects of coils containing metofluthrin, field tests were conducted according to the method of Yap, et al. [6], using private residences in Bogor, Indonesia. The results are shown in Table II. In these tests, 95% of the mosquitoes captured were Culex quinquefasciatus, and coils containing 0.005% metofluthrin exhibited an efficacy exceeding that of coils containing either 0.03% transfluthrin or 0.2% d-allethrin.
