Pests in Gardens and Landscapes
Grape erineum mite—Colomerus
Adult mites are wormlike, light yellowish white, 0.2 mm long and one-fourth as wide. They have two pairs
of legs and are much smaller than spider mites.
Young leaves show bright pinkish or reddish swellings on upper surfaces. Corresponding areas on lower
surfaces are concave and densely lined with a felty mass of plant hairs.
Control is not necessary. Early leaf distortion can be tolerated with no resulting loss in yield.
