New evidence published online in Pest Management Science reports the first signs of resistance to pyrethroid insecticides in a population of mosquitoes from Marin County, California. The species in question is not only a major pest, but also acts as a vector of West Nile virus, a virus that spread rapidly westward across the United States after it first invaded the new world in New York in 1999.
