European red mite (Panonychus ulmi)
Twospotted spider mite (Tetranychus urticae)
Pest description and damage Several species of spider mites can cause damage to flowering cherries. Appearance of these mites varies with the species, although all spider mites are 0.02 inch 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. Twospotted 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, which causes leaf stippling, bronzing, and possibly drop. The reduction in photosynthesis causes loss of vigor and yield.
