Efficacy and Nontarget Effects of a Spinosad-Based Larvicide in Minnesota Vernal Pools and Cattail Marshes.

Larvicides that contain spinosad, a bacterial metabolite, are used to control mosquitoes in diverse aquatic habitats. These same habitats are home to other invertebrates, including Crustacea-fairy shrimp, isopods, and amphipods-and mollusks-fingernail clams and freshwater snails. A double-blind study evaluated the effects of Natular® G, a granular treatment containing spinosad, on spring Aedes spp.

ABSTRACT. The Asian exotic mosquito Aedes japonicus was 1st collected in Minnesota in 2007 and was well established in parts of the Metropolitan Mosquito Control District (MMCD) by 2008. Surveillance strategies were devised for 2009 to track the expansion of its range through MMCD and to direct control efforts.
