Apple growers should have their codling moth pheromone traps in place now. See the April 12 edition of Facts for Fancy Fruit for details of where traps and pheromone lures can be purchased. Traps should be checked for moths several times per week, if not daily. Pheromone lures should be replace about every 3 weeks. Growers should use the catch data to improve the timing of their insecticide applications. In the May 11, 2015 edition of Facts for Fancy Fruit, I went through the determination of biofix and calculation of degree days in our orchard at the Meigs Farm near Lafayette last year to demonstrate how the traps can be used.
