Codling Moth, European Red Mite
Codling moth remains the key pest that poses a threat to apples. This is also a time to consider a preventive miticide application for those using this approach in specific orchards or cultivars.

Codling Moth
Egg hatch degree-day models range from about 300 DD in Henderson County to about 440 DD in lower-elevation Cleveland County. In Henderson County, this week is optimum timing for an initial insecticide in orchards with historically low population densities. In orchards with moderate to high populations of codling moth, last week was optimum timing for the first insecticide application. In orchards using mating disruption, it is doubtful that an insecticide is necessary unless pheromone traps are consistently capturing moths.
