Studies on codling moth control in the granite belt

Abstract

The literature on Cydia pomonella (L.) in Queensland is reviewed. The details of six orchard trials during 1949-50, 1954-55 and 1956-57 are given. The materials used in the several spray programmes were DDT, DDD (TDE), diazinon, dieldrin, endrin, malathion, methoxychlor, and parathion. Treatments were applied according to pre-determined programmes for each season, additional sprays, either alone or in combination, being used to control pests other than codling moth. The results illustrate the variation in codling moth populations between orchards and seasons. Under the conditions of these trials none of the newer materials tested gave better results than DDT. It was concluded, therefore, that alterations to the existing codling moth spray programme cannot be justified.
