Many orchard pest management programs in North America revolve around tactics for controlling the codling moth, Cydia pomonella. Conventional chemicals used for codling moth control include organophosphate (OP) and carbamate insecticides. However, the decreasing effectiveness of some OPs in controlling codling moth, the possible development of cross-resistance to carbamate insecticides, and the negative effect of pyrethroid insecticides on biological control agents of other orchard pests have stimulated research and development for alternative orchard insecticide chemistries and control tactics. Two alternative approaches for codling moth management that show promise are the use of synthesized insect growth regulators and mating disruption. Alternative insecticides available for control of other apple pests (leafrollers, leafminers, etc.) are also discussed.
