Volume 57 Number 19 Date 08/23/2012 CODLING MOTH - Numbers have declined after a prolonged second flight. Counts this week ranged no higher than eight moths per trap. The average from August 17-23, three moths per trap in 20 orchards, is the lowest since the earliest moths began emerging last May. At most orchard locations, the second flight has been smaller but lengthier than the first. APPLE MAGGOT - Emergence continued in the southern and central counties. A noteworthy increase from 1-5 per trap was reported from the Rochester monitoring site, although the overall total is not especially high. The weekly high count was 10 flies on a red sphere at Gays Mills in Crawford County. Many growers have applied their last spray of the season with the expectation of reduced fly activity by early September. STINK BUG - Adults and nymphs have been observed on the undersides of leaves in southern Wisconsin apple orchards, signaling the potential for fruit injury prior to harvest. Growers are encouraged to monitor fruits for evidence of feeding by these insects. A single adult or nymph can injure many apples and damage may not develop until after the fruits are in storage. --Krista Hamilton, DATCP Entomologist
