Detection and monitoring of emerald ash borer populations is currently very difficult because of the lack of effective lures & traps. In 2003, we determined whether girdled green ash trees, green ash trees injected with herbicide using a hypo-hatchet, or cut green, white or black ash logs could be used to attract & trap adult beetles. Sticky bands, roughly 30 cm wide, consisting of plastic wrap & Tanglefoot, were placed on the trunk of the healthy trees, treated trees (girdled or herbicide), and cut logs at 3 sites. Girdled trees were significantly more attractive to beetles than healthy tree, cut logs or herbicide injected trees. Moreover, girdled trees functioned as a sink for eggs at low ash borer densities but not in high density populations. In 2004, we compared healthy green ash with girdled trees, trees that were wounded but not girdled, and trees that were stressed with a basal herbicide application but not wounded. Numbers of beetles on sticky traps were compared on the trees at the three wooded sites to determine if girdling, a labor-intensive process, was necessary or if more efficient methods of stressing ash trees were equally effective. Bark was peeled & larval density was determined on the trunk & canopy of trees of all treatments. Results will be used to refine detection & survey programs in 2005.
