At elevations greater than 2000 ft, such as Henderson County, the insect situation has not changed from last week. We remain in that timeframe where the threat of damage by direct pests such as codling moth, OFM, apple maggot and brown marmorated stink bug are at their lowest level. This low-threat period is expected to last for another two weeks, when second generation codling moth emergence is expected to begin.

Off the mountain in lower elevation piedmont sites, codling moth degree-day accumulations are at about 1330. Depending on pheromone trap captures and occurrence of damage by first generation codling moth, an insecticide spray against the second generation is recommended between about 1450 to 1550 DD; 1450 in orchards with moderate pest density (e.g., trap captures exceed 3 to 5 moths per trap per week) and 1550 in orchards with low pest density (e.g., trap captures are less than 2 to 3 moths per week). These timings are predicted to occur later this week to early next week.
