If you are not routinely monitoring fields for cutworm feeding, this is a good time to target initiation of scouting in the Auburn area.
This is the point that black cutworm larvae emerging from eggs laid by these moths will be big enough to begin cutting corn stems. A significant capture is used to initiate the degree day model described below ( Table 2).īased on average temperatures at Auburn, we expect that 300 degree days will be reached by May 18. A significant capture is defined as 8 or more moths over 2 nights. We received a significant capture of black cutworm moths at Auburn on April 23 (Table 1.2). We continue to capture moths in our pheromone trapping network.
