Wheat Curl Mite

Aceria tosichella

The wheat curl mite (WCM) is widely distributed in North America and around the world, wherever wheat is grown. These tiny mites (family Eriophyidae) are important vectors of wheat streak mosaic virus (WSMV) which is one of the most destructive wheat diseases in western Kansas. They are also vectors of the High Plains Virus, a disease of wheat and corn in the Great Plains, and Triticum Mosaic Virus (TrMV). Combined infections of WSMV and TrMV can be especially damaging to wheat.
