Codling Moth Threat Declines, Stink Bug Populations on the Rise

Codling moth: Second generation flight of the codling moth is complete or nearly complete in all regions except for elevations >2500 ft. In lower elevation orchards (less than about 1200 ft), third generation adult emergence will begin this weekend based on degree-day predictions. However, if populations have not been problematic up to this point in time, it is highly doubtful that problems would arise this late in the year.

Brown Marmorated Stink Bug:  Based on DD accumulations at three different production sites (Cleveland, Henderson and Wilkes Counties), emergence of first generation adults is about 40% complete in the lower elevation of Cleveland County (see graph below) and is just beginning in Wilkes County. Now is an important time for insecticidal control of BMSB in orchards at elevations 1500 ft and lower. Emergence in Henderson County is predicted to begin on 13 August. See the 20 July update for BMSB insecticide recommendations.
