DISTRIBUTION OF PHYTOPHAGOUS AND PREDACIOUS MITES ON APPLE TREES IN NOVA SCOTIA

Abstract
The relative densities of phytophagous and predacious mites within mature apple trees were examined. The eggs of phytophagous mites Aculus schlechtendali (Nal.) and Panonychus ulmi (Koch) were more numerous in the lower position of the tree while the reverse was true for the predacious mite Zetzellia mali (Ewing) and its eggs.
