An area-wide approach to manage codling moth, cydia pomonella, was implemented in the fruit-growing region north of Grand Rapids Michigan in the spring of 2004. Twenty growers participating on over 2300 fairly contiguous acres of apple utilized pheromone-based mating disruption, codling moth granulosis virus, and some recently registered insecticides to effectively control codling moth. Captures of male codling moth in pheromone-baited traps were significantly reduced from 1st to 2nd generation. Codling moth injury to fruit was 76% lower in area-wide orchards at harvest compared to non-disrupted orchards outside of the project. Area-wide orchards incorporating codling moth virus sustained 0.5% fruit injury compared to 2% injury in non-disrupted orchards outside of the area-wide project. Industry collaborators have expressed strong satisfaction with the program outcomes, and indicated their desire to expand the project in 2006.
