Sweet Corn Pheromone Trap Network for Western New York,
This is a seasonal scouting report giving growers in the Western New York area information on the presence of sweet corn pests and recommendations on scouting and thresholds. The report is written by Abby Seaman, NYS IPM's Area Extension Educator for Vegetables.
ECB E catches are mostly down from last week; the cooler weather has probably slowed down their emergence from the pupal stage, I don't think we've reached the peak. Z race moths were caught outside the Eden area (where we historically only catch Z race moths) in Lockport this week. No one I've talked to has found any egg masses in corn yet. There's a CEW trap up in Eden, where CEW larvae were found in early plantings a couple of years ago. Two CEW moths were caught in that trap this week. Traps put up early at a couple of other locations last year didn't catch any early CEW.
The numbers below are the weekly total for each location.
