Technical Abstract: Three types of experiments were conducted this year that relate to improving the monitoring of codling moth in apple and pear orchards. The Biolure 10X lure was found to catch more moths than the Superlure (Bubble lure) in orchards treated with either 200 or 400 Isomate C+ dispensers or 100 or 200 Isomate C-tt dispensers per acre. The Pherocon DA (pear ester) lure was found to catch more moths than sex pheromone lures in Anjou and Comice orchards under mating disruption. The DA lure caught an equivalent number of moths as the pheromone lure in Bosc blocks, and caught significantly fewer moths than the pheromone lure in Bartlett. The use of a non-white delta traps eliminates the incidental capture of honeybees that often occurs in orchards early in the season. However, color traps (orange, red, and green) caught more muscoid flies than white traps. Painting traps with these three bright colors (glossy paint) significantly increased the capture of codling moth possibly due to an elevated UV reflectance.
