OSU Dept of Entomology

Objectives:

  1. Continue the cooperative pheromone trapping program to validate management models and to maintain necessary standards.
  2. Continue developing the earworm management model to aid in determining if and when fields should be protected from corn earworm using insecticides.
  3. Establish criteria for defining economics of earworm losses so that the management models developed can be based on economic threshold values for earworm control.
