Using a multicriteria risk model to guide ground surveys for emerald ash borerThis article is part of a larger document. View the larger document here.
The emerald ash borer (EAB) (Agrilus planipennis) is an exotic wood boring beetle from Asia that has become a major pest of ash trees (Fraxinus spp.) in the Midwest. The insect has spread from its initial invasion site in southeastern Michigan aided by human movement of firewood, nursery stock, and other wood materials. Well-established populations of EAB have been found in the Upper Peninsula (UP) of Michigan, an area relatively isolated from the initial invasion site. This has prompted questions about the likelihood of other existing populations in the UP and the possible use of landscape characteristics to predict the locations of EAB satellite invasions.
