Brown marmorated stink bug continues to be the primary insect of concern, and will be through September.

First generation brown marmorated stink bug (BMSB) adults continue to emerge throughout most of the region. However, temperatures cooler than normal have delayed emergence compared to previous years. Based on our degree-day model (see below) first generation adult emergence has not yet begun in Haywood County, and is not predicted to begin until next week. In Henderson County, emergence is still in the early stages, with only about 12% of emergence complete, while in Wilkes and Lincoln Counties approximately 33% and 63% of adults have emerged, respectively.

It is important to remember that this model only predicts the time of adult emergence, not population intensity. While pheromone traps are the easiest method to determine population density, a threshold level is still in the preliminary stages. We do know, however, that we have not observed damage when cumulative trap captures remain below 5 adults per trap.
