Interpretive Summary: Fresh sweet cherries exported to Japan from the United States must be fumigated with methyl bromide to control the codling moth. Recent regulations may restrict future use of methyl bromide. An alternative method to quarantine security is the Systems Approach where normal commercial operations cumulatively eliminate infested fruits. The first step in the Systems Approach is field control. In this study, moth traps were set up in cherry and apple orchards to compare the relative frequency of adult male moths. The apple orchards had ten times the number caught in the traps than did the cherry orchards. Other sampling methods found no codling moth larvae in the cherry orchards. This information helps in developing a Systems Approach for exported cherries.

Technical Abstract: For eleven weeks in the spring of 1999, pheromone traps were placed in cherry and adjoining apple orchards and two isolated cherry orchards in order to collect adult male codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae). On average, the cherry orchards had 10% of the moths found in the corresponding apple orchards. No moths were found in some cherry orchards. Extensive banding of cardboard strips, used to collect mature codling moth larvae, were installed in cherry orchards with moth catches, but no larvae were collected. Some adult moths were collected at the isolated cherry orchards, but at numbers much lower than those in apple orchards. This study suggests that cherry orchards do not attract male codling moths, which may have application in the development of future strategies for maintaining quarantine security in exported fruits.
