Second generation codling moth remains a potential threat throughout the region. Degree-day accumulations range from 1320 in Henderson County to about 1660 in Cleveland County. Under low population densities when a single insecticide application generally provides the necessary level of control, the optimum timing is between 1400 and 1450 DD after biofix. Hence, in Henderson County and similar elevations, that timing is this week – 1400 DD is predicted to occur on Friday. In lower elevation sites, an application targeting codling moth should be considered if one has not been made in the past week. Insecticidal control of second generation is generally not necessary in orchards using mating disruption, but pheromone trap captures should be used to verify low densities. Moth captures should remain below an average of 3 cumulative moths/trap in mating disruption orchards, otherwise an insecticide application may be warranted.
