As corn begins to enter into the ear and kernel development stage across portions of the corn-growing region, insect concerns are also on the increase. The annual western bean cutworm flight is just beginning this growing season in a portion of the Plains states, with a few traps in Nebraska recording their first low western bean cutworm moths in the last week.
