Technical Abstract: In order to develop a systems approach for codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), that will allow export of Pacific Northwest (Washington and Oregon) and California cherries to Japan, cherries were shown to be poor hosts for codling moth. Codling moth pheromone traps were placed in 7 commercial cherry orchards (3 near Wapato, WA and 4 near Stockton, CA) about 5-7 weeks before cherry harvest. All selected cherry orchards were near either apple, pear or walnut orchards, which are better hosts for codling moth. At least 10,000 harvested cherries from each orchard were examined under a dissecting microscope for the presence of codling moth larvae. Even though pheromone traps showed that codling moth was present in the cherry orchards before harvest, no live codling moth larvae were found on any of the harvested cherries. These results show that a systems approach, which relies on the incorporation of production, harvesting, and packaging practices to satisfy quarantine requirements, should be applicable to US cherries.
