Name of the product: Metofluthrin 93%
Metofluthrin is an exciting novel pyrethroid discovered by Sumitomo
Chemical Co., Ltd.
It was registered in Japan in January 2005 and has now been under worldwide
development for envi- ronmental health use. Metofluthrin has extremely high
knockdown activity against various insect pests espe- cially mosquitoes, as
well as relatively high volatility and low mammalian toxicity. This is applicable
to not only existing formulations and devices such as a mosquito coil and a
liquid vaporizer, but also various new type products such as a fan vaporizer, a
paper emanator and a resin emanator. It is noted that knockdown activity of
Metofluthrin is more than 40 times higher than that of d-allethrin against
southern house mosqui- toes in a mosquito coil formulation. This paper
describes the discovery story, insecticidal efficacies in various formulations,
synthetic methods and safety evaluations of Metofluthrin.
