The Emerald Ash Borer (Agrilus planipennis. While it was first found in Michigan in 2002, it is likely that the beetle population had been established quite a few years before discovery. Just under the bark, S-shaped larval galleries will confirm the presence of EAB. A map showing the current North American distribution of the emerald ash borer is available from the Cooperative Emerald Ash Borer Project. "Emerald Ash Borer (Agrilus planipennis)." Hadley, Debbie. Ash stand severely damaged by emerald ash borer. In northeastern North America, five species of native ash have been attacked by emerald ash borer. ).Native to China, Mongolia, North Korea, South Korea, Japan, Taiwan, and the Russian Far East, the emerald ash borer beetle (EAB) was unknown in North America until its discovery in southeast Michigan in 2002. Confirmed observations of Emerald ash borer submitted to the NYS Invasive Species Database. All five of these species occur in Canada and all but blue ash are highly susceptible. 2012. Adult emerald ash borer beetles are a dark metallic green bullet shaped insects that are approximately 8.5 mm in length. However, recent surveys in Canada suggest that some native parasitoids are having an impact on emerald ash borer populations and may potentially be exploited as biocontrol agents. The Emerald Ash Borer's habitat that it invades are places with ash trees like Ontario, Alberta, Quebec and many more provinces that spreads across Canada and neighboring countries like the USA. Data from tree ring analysis indicated that the beetle had probably been present in those areas since the early 1990s. In natural forest settings, ash is very common. The Emerald Ash Borer (EAB), Agrilus planipennis, Fairmaire, an Asian invasive alien buprestid has devastated tens of millions of ash trees (Fraxinus spp.) This helps protect habitat quality for a variety of aquatic organisms. in hardwood forests. Green ash, white ash, black ash, pumpkin ash and blue ash, Other native and exotic species of ash (Fraxinus spp.). Although its natural habitat is in Asia (China, Japan, Korea, Taiwan, and Russian Far East), it made its way to North America in 2002. Fairmaire) is a highly destructive invasive pest that arrived from Asia, most likely in untreated ash wood used for packing material. Under-bark temperatures where the prepupae overwinter are often higher than air temperatures. The emerald ash borer lives in any forested area with a population of ash trees, including black ash, green ash and white ash. (Fig. The larvae (the immature stage) feed on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients, and ultimately killing the tree. Since 2002, the emerald ash borer has been detected in 21 (as of July 2013) states and has killed tens of millions of ash trees. Emerald Ash Borer (Agrilus planipennis) *Established in Michigan* Identification: • Bright, metallic green with purple abdominal segments under its wing covers • Length is approximately ½ inch • Can fit on the head of a penny • Larva are worm-like • Create D-shaped exit hole in the tree . are being threatened by the emerald ash borer, a half-inch metallic green insect (DCNR, n.d.). The Emerald Ash Borer is an invasive species of beetle with a distinctive metallic green color that … Emerald ash borer (Agrilus planipennis Fairmaire) has rapidly become the most important pest of ash trees (Fraxinus spp.) As ash trees in forests die, gaps form in the forest canopy, allowing light to reach understory vegetation. The emerald ash borer has only one generation per year in the south of its distribution area in Michigan. All eastern North American ash species are susceptible to EAB including green, white, black, blue, and pumpkin ash. The threat to ash trees comes from the ash borer larvae which feed on the interior of the ash … Larvae hatch from the tiny (0.6 by 1.0 mm) disk-shaped eggs after one to two weeks of incubation, depending on the temperature.
