WNY Sweet Corn Trap Network Report 8.7.12

European corn borer numbers remain low again this week.  Corn earworm numbers are up at a few locations, with numbers high enough to indicate the need for a 4-5 day spray schedule (see the chart below).  Fall armyworm were caught at only a few locations, and in low numbers, this week.  Western bean cutworm numbers are generally down, indicating that peak flight has occurred at most locations.  Robert Hadad scouted fields in Eden, Lockport, and Spencerport for western bean cutworm eggs, and found one egg mass in a field in Eden, where numbers were the highest last week.  WBC is unlikely to be a problem in other areas where trap catches were lower.  He found very little damage or infestation of any other worm pest in the fields he scouted, a reflection of the low trap catches.  But not a good idea to decide not to scout your fields because the trap catches are low!
