Living with emerald ash borer: which trees were attacked first in Michigan's Upper Peninsula?
College of Forest Resources and Environmental Science
The exotic emerald ash borer (EAB) (Agrilus planipennis)(Coleoptera: Buprestidae) is established in Lower Michigan and some surrounding states. At high population densities, all green, black, and white ash trees are apparently susceptible to attack and can be expected to die. The first record of this insect in Upper Michigan was from Brimley State Park in the eastern Upper Peninsula of Michigan. In the fall of 2005, as part of an ongoing risk-based detection survey, larvae were extracted from a trap tree that had been used at the site since 2004. The insect was most likely introduced via infested firewood. Subsequently, an eradication effort was made by cutting and removing all of the ash trees within one-half mile of the infested trees. This provided the opportunity to identify additional infested trees within the park and to collect disks from all trees for growth ring analysis.
