Which mite is it? Identifying the mites in wheat fields

In South Dakota, the most commonly encountered mites in wheat are wheat curl mite and brown wheat mite. In addition to feeding, wheat curl mites are vectors of Wheat streak mosaic virus.

There are other species of mites that may also be observed in wheat, but generally do not reach populations large enough to cause significant injury.
