There may be a partial second summer brood of moths in September, especially in southern Ohio. The time period occupied by each stage of the codling moth during the summer is usually shorter in southern Ohio than in northern Ohio because higher temperatures accelerate development. The wing-type sticky trap with the codling moth pheromone lure should be hung in the tree at bloom. See North Central Regional Extension Publication 359, Insect Traps Home Fruit Insect Control for further information on where to obtain traps. Control Natural control Birds are important predators of hibernating larvae that are under loose bark.
Parasites can attack eggs and larvae of the developing codling moth.
Remove and destroy the strips after cocoons are formed. Before the bands are attached, the bark should be scraped to remove loose pieces that would prevent a tight fit by the strips. Repeated applications of insecticide every 10 to 14 days are usually needed from petal-fall to near harvest. Sprays are most effective when applied just before newly hatched larvae attempt to enter the apples. If you are using a pheromone trap to monitor codling moth, the best time to spray is two weeks after the first moth catch or one week after a peak catch.
