Aculus fockeui
Pest description and damage Peach silver mites are tiny (about 0.006 inch in length), four-legged eriophyid mites, yellow to pinkish white, and somewhat wedge-shaped. On rare occasions when very high populations of peach silver mite survive the winter, they produce symptoms on the unfolding leaves. Symptoms consist of minute, yellow spots, and a tendency for the leaf edges to curl toward the midrib. Ordinarily, however, most injury is not noticed until mid- to late summer, when heavily infested leaves take on a silvery appearance.
Biology and life history The mites overwinter as females in bark crevices, around buds, and under bud scale. They move to the leaves soon after budbreak in spring. Later in the season, they are primarily on the lower leaf surface. Before leaf fall, females move to overwintering sites on the tree. Many generations are produced during the season.
Management-biological control
Treatments applied specifically for control of peach silver mites rarely are needed and should be avoided, because peach silver mites serve as early season food for predaceous mites, which in turn reduces populations of other pest mites.
