Western bean cutworms count rising and eggs hatching

We have seen a large increase in Western Bean Cutworm catches (see figure), which is typical for this time of year. Given the heat in the forecast later this week, it might be safe to say that we are into peak flight.  We have also heard of eggs hatching—as more adults emerge, more eggs will be laid. Now is the time to scout your corn for egg masses, especially if they have not tasseled yet. Economic threshold is more than 5-8% of corn (10 plants in 10 locations) with egg masses.
