Volume 54 Number 18 Date 08/28/2009 BLACK LIGHT TRAPS - Very few moths were registered in black light traps during the period of August 21-27, with the exception of dingy cutworms, which appeared in high numbers at Chippewa Falls (60), East Troy (144), Janesville (61), Manitowoc (33), Marshfield (58), Sparta (97), and Wausau (156). The second flight of corn borers continued at low levels, and spotted cutworms were reported from Manitowoc, Marshfield and Wausau. WINTER CUTWORM - Reports of activity were received from Dane, Monroe and Manitowoc counties in the past two weeks. Moths captured late in the season are an indication of a potentially large larval population which may or may not materialize over the winter months or next spring. Last winter considerable alarm was generated when the cold-tolerant larvae were observed invading homes and advancing over the snow. Contrary to forecasts, no damage to alfalfa or small grains was reported or observed in the state in 2009. -- Krista Hamilton, DATCP Entomologist
