Now that most corn is past the stage of being injured by early-season pests such as wireworms, white grubs, and black cutworms, our attention needs to turn to mid-season insects. It is estimated that 30 percent of the corn acres will be planted to Bt corn this year, and in those acres, European corn borer injury will be almost nonexistent. However, most other corn insects are unaffected by Bt corn and their injury probably can be found on any type of corn hybrid regardless of the plant genetic background.
