How to Manage Pests

Pests in Gardens and Landscapes

European red mite—Panonychus ulmi

Immature mites are bright red, except just after molting, when they appear bright green. The green color turns to red after the mites resume feeding. Adults are dark red and have white spots at the base of the long hairs on the back.

Life cycle

Damage

Mite feeding causes leaves to lighten in color, becoming mottled or stippled. Prolonged feeding by heavy populations eventually causes leaf bronzing or burning.

Solutions

Numerous predators feed on red mites. In-season sprays for red mites are not usually necessary or advisable in the home orchard.
