Brown wheat mite

Brown Wheat Mite
Petrobia latens (Müller)

Dark mites, 1 mm long, with front legs longer than the body. Feeding injury causes a mottling of the leaves giving them a bronzed or yellow appearance. Injury occurs early in the season, many times on hills in grain fields where moisture stress is more likely. Damage is more severe in cereal and cereal rotations or along margins of fields where grass or cereal was grown the previous year. Host plants: cereals, onions, carrots, alfalfa, iris, gladiolus.
