Foliage damage caused by feeding of MITES.

 

 

 

Species

Eotetranychus spp.
Oligonychus spp.
Tetranychus spp.

Common Hosts:

Hardwoods
Softwoods
Nursery stock in beds especially prone to mite infestations.

Description

Adult -- approximately 0.5 mm long; oval-shaped, wingless body; red, green, or white in color, 4 pairs of legs (not an insect).
Nymph -- similar to adult, 3 pairs of legs.

Importance

Hot, dry weather favors the buildup of mite populations. Excessive use of insecticides for other problems is conducive to a mite problem. Severe infestations may place an undue stress on infested trees.

Signs of Infestation
Foliage discoloration: chlorotic stippling followed by yellowing or bronzing. Silk webbing and very small grayish-white skins on infested foliage. Hold sheet of white paper beneath suspected leaves and strike leaves sharply. Mites will appear to be small dark, moving spots.
Control
Minimize insecticide use whenever possible, especially in the nursery setting. Use an approved miticide when necessary. Inspect trees regularly during late summer, droughty weather.
