Abstract

A 2-year study on management of apple pests was carried out on six orchards in the interior of British Columbia. Sample techniques and treatment thresholds were satisfactory for most pests with the exception of fruittree leafroller, Archips argyrospilus (Walker), western flower thrips, Frankliniella occidentalis (Pergande), and the mirid Campylomma verbasci (Meyer). The number of chemical sprays per orchard averaged eight when the study was initiated. In 1973, the sprays required for pest control were reduced to an average of 5.6 per orchard, and in 1974, this figure was further reduced to 3.1. This reduction in chemical sprays was accomplished without an increase in insect or mite injury to fruit or foliage.
