ECB-E race trap catches are picking up at some locations this week, indicating the beginning of the second generation flight.  Z race catches are mostly 0 to the low single digits this week.  More moths flying makes it more important to scout the ear zone of plants in silk stage for egg masses and newly hatched larvae.  Remember that egg masses take about 100 base 50 degree days to hatch, and with the weather that’s being predicted for later this week, we’ll be accumulating over 30 DD per day and it could be as few as 3 days between egg deposition and hatch.

Most trapping locations caught no corn earworm this week, and where they were caught, numbers were no higher than 5.  Low numbers of fall armyworm and western bean cutworm were caught at scattered locations.
