Overall insect pressure remains low in most areas. While degree-day accumulations coincide with early egg hatch of the third generation in lower elevation orchards (e.g., Cleveland, Lincoln Counties), this generation should not require control unless damage from previous generations is evident, which seems to be rare. In higher elevations (e.g., Henderson County), DD accumulations coincide with the tail end of second generation egg hatch, and pheromone trap captures remain low. OFM pheromone traps captures are also very low throughout the area.

Based on pheromone trap captures in multiple apple orchards, first-generation adult brown marmorated stink bug emergence continues in the mountains, and has slowed down considerably in lower elevation orchards (less than 1000 ft elevation). Populations to date do not appear to be especially high, so two-week interval applications should be sufficient in those locations where protection is of greatest need – i.e., fresh market production.
