Are Worms Eating Up Your Profits?!?!
If your packers and processors are reporting worm holes, or worms, it is likely you have a high population of codling moth (CM, Cydia pomonella) and/or oriental fruit moth (OFM, Grapholita molesta) that are causing economic losses in your fruit. It is time to take steps to prevent this damage. The tools that are used to control these pests include pheromone trapping, implementing mating disruption pheromones to prevent mating, improving spray timing using degree-day models and trap data, improving spray coverage, and using the most effective insecticides and viruses at the recommended timing. Please see following .pdf for steps to control internal leps.
