Proposal Abstract

Codling moth has become a serious threat to the profitability of the $280M NY apple industry. Over the past 2 seasons, many more practical and effective solutions have been registered for use to combat this pest including the concept of area-wide mating disruption (AWMD) and some new but environmentally softer insecticides that have a new mode of action. This project will help the industry determine how to integrate the use of mating disruption pheromones over a large acreage with the question of timing insecticide applications to control this pest. The project will improve control of codling moth, prevent market rejections of infested apples, minimize grower costs for control of worms in fruit and still satisfy the "zero" tolerance for worms in fruit. Processors and packers will benefit by increasing packing and processing efficiency since they will not have to sort out infested apples. Consumers of NY fruit will be assured that fruit has been produced under IPM methods to provide them with worm-free fruit.

Final Report Summary Statement

This project focused on refining technology to control codling moth. This project potentially saved ~$2M in fruit value to the growers. We wanted to validate the insect development model (“PETE”) and the trap-based degree-day model while integrating new control technology including mating disruption pheromones, trap data, and new insecticides. Relying on the PETE model under high populations of internal lep pests results in more fruit damage if only 2 sprays are applied for the first generation of codling moth; including a third spray against the delayed egg hatch of the first generation under these conditions improves control. Growers with low-moderate trap numbers can rely on the PETE model for adequate control. If growers implement mating disruption pheromones, they reduce the population to allow them to minimize insecticide applications to 1-2 per generation. Growers have more confidence in using mating disruption and new classes of insecticides to prevent wormy apples.
