Codling Moth:  We remain in the timeframe when codling moth is the key insect of concern in apples. Degree-day accumulations since biofix range from about 360 in Henderson County (2100 ft elevation) to about 550 in Cleveland County (850 ft). First generation codling moth can remain active through about 600 to 800 DD, depending on population density. Generally, the higher the population the later activity declines.
