Blue oat mites attack seedling winter cereals and when heavy infestations occur the leaf tip withers and the seedling can die. They lay eggs in the soil which hibernate throughout winter, allowing populations of mites to build up over a number of years, causing severe damage if crop rotation is not practised.

Brown wheat mites attack wheat, barley, triticale, oats and cotton. Populations usually reach troublesome levels only under very dry conditions.

Peanut mites attack peanuts with high populations resulting in shedding of lower leaves and eventual plant death. Economic losses from peanut mites are mainly associated with young crops during dry weather.

Two-spotted mites attack cotton, soybean canola, lucerne, peanut, mungbean, navy bean and azuki bean. Heavy infestations will result in leaf desiccation, leaf drop and yield loss.
