Objective:
To develop an effective mating disruption formulation for dogwood borer.

Approach:
Trials will be conducted in commercial apple orchards. The ability of pheromonal and antagonist formulations to disrupt mate finding will include the following formulations: (1) Z,Z-3, 13-ODDA alone (major sex pheromone component); (2) the 3-component DWB sex pheromone blenod; (3) E,Z-3, 13-ODDA alone (antagonist alone); and (4) an antagonist blend [60.5% (E,Z)-3,13-ODDA (antagonist), 22.7% (Z,Z)-3,13-ODDA (major sex pheromone component), and 16.8% other ODDA isomers]. Dispensers will be deployed in early May and male flight activity will be monitored through early November using the optimized pheromone blend in monitoring traps.
