he exotic emerald ash borer (Agrilus planipennis)(Coleoptera: Buprestidae) is established in a number of states, including Michigan, Indiana, and Ohio, and in one Canadian province, Ontario. At high population densities, all green, black, and white ash trees are apparently susceptible to attack and can be expected to die. Emerald ash borer larvae develop in the phloem of ash trees in stems and branches above approximately 2.5 cm in diameter. Removal of ash from high priority areas such as those stands in close proximity to outlier populations will reduce the population density of this insect.
