During the past week both brown marmorated stink bug and apple maggot populations increased in number.

Brown marmorated stink bug

BMSB pheromone trap captures in Henderson County increased considerably during the past week, as noted below in the figure that compares trap captures during the past three years. This trend of increasing BMSB trap captures is expected to continue in higher elevation locations (Haywood, Henderson and Wilkes Counties) where less than 50% of first generation adults have emerged to date (see the updated emergence figure below). In lower elevations such as Lincoln County, over 80% of first generation adults have emerged, so it is less likely that populations will rise significantly in those locations. The bottom line is that in these higher elevation orchards, late-maturing fruit will continue to be susceptible to damage for the rest of September.
