Abstract
The major pests of apples and pears are codling moth,. Cydia pomonella (L.), light-brown apple moth, Austrotortrix postvittana (Walk.), European red mite, Panonychus ulmi (Koch), Bryobia mite, Bryobia Praetiosa Koch, red spiders, Tetranychus telarius L. and T. lambi Pritchard and Baker, pear leaf blister mite, Eriophyes pyri (Pgst.), woolly aphid, Eriosoma lanigerum (Hausm.) fruit fly, Strumeta tryoni (Frogg.) and San Jose scale, Quadraspidiotus perniciosus (Comst.). The basic spray schedule includes oil in the dormant or green tip stage, arsenate of lead and lime in the calyx stage, 5 applications of DDT, 0.1%, between early Nov. and early Feb., with 2 additions of Kelthane 0.05% against mites, and finally 0.2% DDT against fruit fly if the presence of flies is indicated by trapping. Lime sulfur, 10 to 100, is used in the dormant season against pear leaf blister mite. [The light-brown apple moth has habits similar to red-banded leafroller in North America].
