Azalea (Rhododendron)-Spider mite

Tetranychus spp.

Pest description and damage Several species of spider mites can cause damage in deciduous or particularly evergreen azaleas. Appearance of these mites varies with the species, although all are 0.02 inches or smaller. Adults and nymphs can be yellowish, greenish, or reddish brown, depending on species. Female European red mites are round with red bodies; males are yellowish-red. Spider mites are oval and yellowish-brown or green with distinctive black spots on the body. Mites damage leaves and fruit indirectly by feeding on leaves that causes stippling, bronzing, and sometimes leaf drop. The reduction in photosynthesis causes loss of vigor.
