The western spotted cucumber beetle (WSCB) is the major insect pest of the Willamette Valley vegetable industry, attacking snap beans, sweet corn, and cucurbit crops.

OBJECTIVES:

• Monitor corn earworm moths using pheromone and black light traps.
• Conduct a statewide pheromone trapping program.
• Conduct a comparison of pheromone traps.
• Study earworm infestation trends
• Study corn earworm overwintering success and spring emergence.
• Produce a sweet corn growth model.
• Conduct an insecticide trial.

OBJECTIVES:

• Refine corn earworm monitoring techniques using pheromone and black light traps.
• Continue developing a statewide pheromone trapping program.
• Study earworm flight and infestation trends that can be used to predict damaging infestations.
• Develop corn earworm and sweet corn development models.
• Conduct insecticide trials to determine if and when sprays are most effectively used.
• Incorporate relevant information into a damage prediction model that can be used for management purposes.

Objectives:

1. Continue investigation of pheromone traps to predict cutworm infestations.
2. Test efficacy of registered insecticides for control of the black cutworm, emphasis on detection and timing.
3. Test insecticide bait for detection and control of black cutworm.
4. Determine when black cutworm gets into to table beets, overwintering and migration.

Objectives:

1. Evaluate the role of planting date on cutworm colonization.
2. Evaluate the role of plant height/age in cutworm colonization.
3. Determine the best time to apply insecticides for the black cutworm based on 1 and 2.
