An area-wide approach to manage codling moth, Cydia pomonella, was implemented in three apple growing regions in Michigan. Thirty growers participating on over 2700 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 and injury to fruit at harvest were significantly reduced on area-wide farms using pheromone mating disruption compared to orchards outside of the project. The overall number of pesticide applications targeting codling moth was also reduced.
