Technical Abstract: The codling moth area-wide management program was highly successful in reducing organophosphate use and in managing codling moth. This success rests on the use of mating disruption for control and may have little to do with an area-wide implementation strategy. However, large scale implementation may have other benefits including reduced problems with a suite of secondary pests. I review the dispersal tendencies of 3 important secondary pest groups of pome fruits and in some cases their natural enemies. I conclude that area-wide or landscape-level approaches are potentially more valuable for these pests than for codling moth. The reviewed species are the 2 leafrollers, pear psylla, and the heteropteran pests. I also discuss unpublished data on movement of pear psylla and natural enemies attacking the leafroller complex.
