Technical Abstract: The Agriculture Research Service funded a five-year multi-institutional project to implement the use of sex pheromones for codling moth in conjunction with the use of other selective control strategies for secondary pests across large contiguous areas of pome fruit production. Twenty-two sites were established in Washington, Oregon, California, and Colorado from 1995 to 1999 involving 533 growers farming 9763 hectares. Growers in the project reduced their use of broad spectrum insecticides nearly 80% while also reducing levels of fruit injury from codling moth. New pest problems developed in some treated orchards and the role of biological control increased only marginally. Following the end of governmental support grower adoption of sex pheromones has continued to increase but few coordinated grower projects remain. Concerns for the evolution of resistance to new insecticides and their impact on biological control remain important for the successful implementation of sustainable IPM programs in pome fruit.
