The emerald ash borer, Agrilus planipennis Fairmaire, is an invasive insect species that was first found in North America in June 2002. Shortly after the Detroit , Michigan discovery, forest health monitoring staff from the Ontario Ministry of Natural Resources (OMNR) and Canadian Forest Service (CFS) determined the beetle was also present in Windsor , Ontario . The Canadian Food Inspection Agency (CFIA) was immediately notified. Surveys conducted in Canada and the U.S. found the beetle was well-established in the Detroit and Windsor areas.
Little information was known about the beetle at the time. Arriving in North America through improperly treated wooden packaging material from Asia , the insect didn’t even have a common English name. Despite substantial research and control efforts, the beetle has continued to spread to new areas. Some of this spread has been natural dispersal, but the long distance spread has been helped by people, especially through the movement of nursery stock or infested firewood from infested areas.
