Three key insect pests are of concern at this time, including codling moth (whose populations are declining), brown marmorated stink bug, and apple maggot.

With codling moth degree day (DD) accumulations ranging from about 1975 in Henderson County to 2350 in Lincoln County, we are nearing the end of second generation flight throughout the region. Pheromone trap captures have been relatively low in the majority of orchards, but there are orchards that continue to have high trap captures and insecticides effective against this pest should continue to be applied.

First generation brown marmorated stink bug emergence is picking up steam at this time. In higher elevation orchards (about 2000 ft), pheromone trap captures have increased during each of the past two weeks, and the major emergence is expected to occur in the second to third week of August. BMSB control in these areas will be particularly important from mid-August to mid-September.
