  1. Further improve earworm pheromone trapping methods using commercially available traps and lures, and validate the relationships found for trap catch and subsequent damage levels.
  2. Continue developing the earworm management model to aid in determining if and when fields should be protected from corn earworm using insecticides.
  3. Continue insecticide trials to define aspects of timing in relation to earworm biology
