Interpretive Summary: Dogwood borer has become an important wood-boring pest of apple orchards in eastern North America. Monitoring traps baited with commercially available pheromone lures for this clearwing moth species have proven largely ineffective due to problems with attractiveness and species-specificity. Recently, the sex pheromone of the dogwood borer was identified and found to consist of three components. Traps baited with this three component blend as well as other experimental blends outperformed commercially available lures. The three component and a two component blend were significantly more attractive than the most attractive commercially available lure. Furthermore, over 97% of all moths captured were dogwood borers in traps baited with these experimental lures compared with as little as 6 % with commercially available lures. Greater amounts of the three- and two component pheromone blends deployed in traps resulted in higher captures of moths, indicating a positive dose-response relationship. Most dogwood borers were captured in traps deployed within commercial orchards, compared with traps in surrounding woodland habitat. These results indicate that growers will now be able to effectively monitor dogwood borer in apple orchards and make informed management decisions regarding need for and timing of insecticide applications.
