Otiorhynchus sulcatus

Tetranychus urticae

Pest description and crop damage These mites are about 0.5 mm in length, have eight legs, and are light tan or greenish with a dark spot on each side. Spider mites feed by sucking the contents out of leaf cells, causing a mottling, stippling and bronzing of the leaves. Their feeding reduces plant vigor and may cause leaves to turn brown and drop.
