Twenty-one sites reporting this week. Five sites reporting European corn borer (ECB)-E and eight sites reporting ECB-Z. Both corn earworm (CEW) and Fall armyworm (FAW) have increased over the last week (see graph below). CEW was caught at thirteen sites with all but one site high enough to require either a 6, 5, or 4 day spray schedule and twelve sites reporting FAW. Western bean cutworm (WBC) continues to decline and was caught at fairly low numbers at twelve sites.
Often at this time of year we are catching CEW at most locations and in high enough numbers that other moths will be controlled by the spray timing needed for CEW. In the absence of CEW, continue to scout for ECB egg masses, and ECB and FAW larvae and feeding damage, using a threshold of 5% infested plants for silking corn.
Average sweet corn trap catches for all reporting sites from 5.25.15 – 8.25.15
