Abstract
Not available – first paragraph follows:
Spider mites and predatory mites can live all year on deciduous trees and vines. During the growing season they colonize the foliage, and during winter they overwinter under bark and in crevices in a state of dormancy (diapause). Spider mites and predatory mites can move from plant to plant by walking or they can be accidentally transferred by other organisms. Spider mites are also known to disperse aerially, and clusters of spider mite females can sometimes be seen on the tips of branches before their dispersal. Some spider mite species drop from leaves on thin silk strands and are picked up by the wind.
