Results from this study will allow us to learn if other tree species besides ash may be threatened by eab in North America. EAB emerges in late spring, flying from June to August. Conversely, much like ashes grown in the nursery trade, the population of emerald ash borer in North America is believed to have originated from a single group of insects from central China and also exhibits low genetic diversity. [8], Eggs are deposited between bark crevices, flakes, or cracks and hatch about two weeks later. Since its accidental introduction from Asia, emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), has killed millions of ash trees in North America. [9] Young trees with bark between 1.5 millimeters (0.059 in) to 5 millimeters (0.20 in) are preferred. [3] They leave tracks in the trees they damage below the bark that are sometimes visible. Emerald ash borer are small, iridescent green beetles that live outside of trees during the summer months. Host range of Emerald Ash Borer. In Canada, emerald ash borer has been detected throughout southwes… EAB Facts: It attacks only ash trees (Fraxiinus spp.). The emerald ash borer is an insect native to Asia but not to the US It attacks and kills ash trees Nearly 100% of ash trees are killed in infested areas Emerald ash borer larvae destroy the cambium of ash trees [45], Animal and Plant Health Inspection Service, "Battle of the Ash Borer: Decades after Beetles Arrived in Michigan, Researchers Looking to Slow Devastation", "Emerald ash borer: A guide to identification and comparison to similar species", https://www.bioadvanced.com/articles/controlling-emerald-ash-borers, "Native Borers and Emerald Ash Borer Look-alikes", "An illustrated guide to distinguish emerald ash borer (, "Emerald Ash Borer Biological Control Release and Recovery Guidelines", "Emerald Ash Borer Invasion of North America: History, Biology, Ecology, Impacts, and Management", "Review of the emerald ash borer (Coleoptera: Buprestidae), life history, mating behaviours, host plant selection, and host resistance", "Bad and good news for ash trees in Europe: alien pest, Department of Agriculture, Environment and Rural Affairs. Emerald ash borer, a beetle native to northeast Asia, was first detected in Michigan in 2002. It’s in every state east of that line except for Mississippi and Florida. Emerald ash borer, a beetle native to northeast Asia, was first detected in Michigan in 2002. Parasitism by parasitoids such as Atanycolus cappaerti can be high, but overall such control is generally low. Approximately 15% of the trees that make up Colorado's urban forest are ash. Common Name: Emerald ash borer Scientific Name: Agrilus planipennis Native Range: Asia Biology & Description: Emerald ash borer has a golden-green body with dark, metallic green wings and a purplish-red abdomen. Robert A. Haack and Toby R. Petrice, USDA Forest Service, North Central Research Station, 1407 S. Harrison Road, East Lansing, MI 48823. [10] Larvae can also survive high heat up to 53 Â°C (127 Â°F). Adult Beetles are metallic green and about 1/2 inch long. lanuginosa. Adult beetles average 3/8″ to 3/4″ long and 1/6″ wide. [9] These J-shaped larvae shorten into prepupae and develop into pupae and adults the following spring. The wasps stun the beetles and carry them back to their burrows in the ground where they are stored until the wasps’ eggs hatch and the wasp larvae feed on the beetles. Mortality from native woodpeckers is variable. Its western range has reached South Dakota in the north down to … [8] Insecticide treatments are not feasible for large forested areas outside of urban areas. Data from tree ring analysis indicated that the beetle had probably been present in those areas since the early 1990s. [9], Sometimes trees are girdled to act as trap trees to monitor for emerald ash borer. You may obtain a free PDF reader from Adobe. It is not native to the United States and was first found in the U.S. near Detroit, Michigan in 2002. Past struggles with Dutch elm disease and current ones with emerald ash borer (EAB) have led the city to implement diversification plans, as well … After emergence, adults feed for one week on ash leaves in the canopy before mating, but cause little defoliation in the process. [8][7] After hatching, larvae chew through the bark to the inner phloem, cambium, and outer xylem where they feed and develop. They are approximately 1/2 inch in length and can fit on the head of a penny. Although studies of American ashes have suggested that they are capable of mustering similar defensive mechanisms, the trees do not appear to recognize when they are under attack. In 2002, the beetle was detected for the first time in North America in the vicinity of Detroit, Michigan, and later in Windsor, Ontario. [42] Three species imported from China were approved for release by the USDA in 2007 and in Canada in 2013: Spathius agrili, Tetrastichus planipennisi, and Oobius agrili, while Spathius galinae was approved for release in 2015. That is in large part because it was introduced to North America where it has no natural predators and its food (ash trees) has no natural defenses. Mastro, V., and R. Reardon (Comps. Host Range of Emerald Ash Borer. He found the beetle in Beijing and sent it to France, where the first brief description of Agrilus planipennis by the entomologist Léon Fairmaire was published in the Revue d'Entomologie in 1888. [27] Many of the specialized predators and parasitoids that suppressed emerald ash borer in Asia were not present in North America. [10], North American predators and parasitoids can occasionally cause high emerald ash borer mortality, but generally offer only limited control. [11][10], The beetle is invasive in North America where it has a core population in Michigan and surrounding states and provinces. Before it was found in North America, very little was known about emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America.

Emerald ash borer (eab) is native to China, Japan, Korea, Mongolia, eastern Russia, and Taiwan. The larva are worm-like. [23][36] In urban areas, trees are often removed once an infestation is found to reduce emerald ash borer population densities and the likelihood of further spread. The emerald ash borer (EAB) is a non-native, invasive insect that was first discovered in North America in 2002 in Michigan. [10] From 2003 to 2016, this population has spread west towards the European Union at up to 40 km (25 mi) per year and is expected to reach central Europe between 2031 and 2036. [8], Outside its native range, emerald ash borer is an invasive species that is highly destructive to ash trees in its introduced range. The potential for widespread mortality of ash is a major concern for several Native American tribes who particularly value black ash for basket-making and as a cultural resource. [8] The insect was first identified in Canton, Michigan, in 2002, but it may have been in the U.S. since the late 1980s. Emerald ash borer is a species native to parts of eastern Asia that was accidentally introduced into North America, probably sometime in the 1990s. (608) 231-9544 TTY/TDD. [8][40][41] Insecticides are typically only considered a viable option in urban areas with high value trees near an infestation. 2017 note that the … (608) 231-9318 Its western range has reached South Dakota in the north down to Texas in the south. [8][10], Other factors can limit spread. [30][31] Other means will be used instead, especially #Biological controls. Ashes used in landscaping also tend to be subjected to higher amounts of environmental stresses including compacted soil, lack of moisture, heating effects from urban islands, road salt, and pollution, which may also reduce their resistance to the borer. [40] Ash trees are primarily treated by direct injection into the tree or soil drench. For a better understanding of the EAB life cycle, watch the video Cycle of Destruction(link is external). As of October 2018, it is now found in 35 states, and the Canadian provinces of Ontario, Quebec, New Brunswick, Nova Scotia and Manitoba. [19] In China, it infests native F. chinensis, F. mandshurica, and F. rhynchophylla; in Japan it also infests F. japonica and F. Many of these lingering ashes were found to have unusual phenotypes that may result in increased resistance. Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. Its western range has reached South Dakota in the north down to Texas in the south. Its western range has reached South Dakota in the north down to Texas in the south. [10] Both males and females use leaf volatiles and sesquiterpenes in the bark to locate hosts. [5][6], The emerald ash borer life cycle can occur over one or two years depending on the time of year of oviposition, the health of the tree, and temperature. To address the concern that eab may attack other tree species in North America, we tested if adults would foliage feed (adults must foliage feed before mating and laying eggs) on several non-ash tree and shrub species (American elm, hackberry, shagbark hickory, black walnut, lilac, forsythia, privet, and fringetree) that are native to North America and are related to the species eab attacks in Asia.  In this study, we collected foliage, offering it to eab adults in lab choice tests, and then calculated how much foliage they consumed of each species during a standard amount of time.  Feeding amounts on non-ash species were compared with those on several North American ash species (black, blue, green, and white ash). Modest though the response was, woodpeckers and nuthatches may be the ash trees’ best hope. [8] It primarily spreads through flight or by transportation of ash bark containing products such as firewood or nursery stock, which allows it to reach new areas and create satellite populations outside of the main infestation. The emerald ash borer, Agrilus planipennis Fairmaire (Figure 1), is a highly destructive wood-boring beetle that feeds on the phloem of ash trees (Fraxinus spp.). [10], Damage and efforts to control the spread of emerald ash borer have affected businesses that sell ash trees or wood products, property owners, and local or state governments. [30][31], Emerald ash borer threatens the entire North American genus Fraxinus. "Exploratory survey for the emerald ash borer, "Interspecific Variation in Resistance to Emerald Ash Borer (Coleoptera: Buprestidae) Among North American and Asian Ash (, 10.1603/0046-225X(2008)37[242:IVIRTE]2.0.CO;2, "Effects of climate on emerald ash borer mortality and the potential for ash survival in North America", "The Upside Of The Bitter Cold: It Kills Bugs That Kill Trees", "APHIS Changes Approach to Fight Emerald Ash Borer EAB", North American Plant Protection Organization, "Removal of Emerald Ash Borer Domestic Quarantine Regulations", "Evaluation of potential strategies to SLow Ash Mortality (SLAM) caused by emerald ash borer (, "Cost of potential emerald ash borer damage in U.S. communities, 2009-2019", "Emerald Ash Borer (EAB) is in Minneapolis", "After Your Ash Has Died: Making an Informed Decision on What to Replant", "Insecticide Options for Protecting Ash Trees from Emerald Ash Borer", "Developing a classical biological control program for, "Biological Control of the Emerald Ash Borer", "Biocontrol: Fungus and Wasps Released to Control Emerald Ash Borer", USDA Forest Service Northern Research Station link to research on EAB, United States National Agricultural Library, https://en.wikipedia.org/w/index.php?title=Emerald_ash_borer&oldid=995582867, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, This page was last edited on 21 December 2020, at 21:03. Volunteers catch the wasps as they return to their burrows carrying the beetles to determine whether emerald ash borer is present. [43][44] Excluding Spathius galinae, which has only recently been released, the other three species have been documented parasitizing emerald ash borer larvae one year after release, indicating that they survived the winter, but establishment varied among species and locations. [44], The USDA is also assessing the application of Beauveria bassiana, an insect fungal pathogen, for controlling emerald ash borer in conjunction with parasitoid wasps. [10], Emerald ash borer primarily infest and can cause significant damage to ash species including green ash (Fraxinus pennsylvanica), black ash (Fraxinus nigra), white ash (Fraxinus americana), and blue ash (Fraxinus quadrangulata) in North America. Since its discovery, EAB has: Once an infestation is detected, quarantines are typically imposed by state or national government agencies disallowing transport of ash firewood or live plants outside of these areas without permits indicating the material has been inspected or treated (i.e., heat treatment or wood chipping) to ensure no live emerald ash borer are present in the bark and phloem. To date, in North America, eab has been found to successfully reproduce only in species of ash. [8] Males hover around trees, locate females by visual cues, and drop directly onto the female to mate. japonica), and in Japan it is reported to infest ash, elm, walnut (Juglans mandshurica) and wingnut (Pterocarya rhoifolia). [24], Without factors that would normally suppress emerald ash borer populations in its native range (e.g., resistant trees, predators, and parasitoid wasps), populations can quickly rise to damaging levels. USDA Forest Service publication FHTET-2004-02. Kentucky Extension specialists suggest selecting uncommon species to replace removed ashes in the landscape. The serpentine feeding galleries of the larvae disrupt the flow of nutrients and water, effectively girdling (killing) the tree as it is no longer able to transport sufficient water and nutrients to the leaves to survive. Science theme: Forest Disturbance Processes, Science Topic: Invasive Species - Emerald Ash Borer, Forest Service Home | USDA.gov | recreation.gov The larvae is worm-like and live underneath the bark of ash trees. Furthermore, most ashes used in landscaping were produced from a handful of cultivars, resulting in low genetic diversity. Emerald ash borer, a beetle native to northeast Asia, was first detected in Michigan in 2002. This methodology is known as biological surveillance, as opposed to biological control, because it does not appear that the wasps have a significant negative impact on emerald ash borer populations.[35]. Hannah, J. Wright State researcher finds emerald ash borer may have spread to different tree. Distribution: One Gifford Pinchot Drive Populations are more scattered outside the core area, and the edges of its known distribution range north to Ontario, south to northern Louisiana, west to Colorado, and east to Massachusetts. In China, three species of ash (Fraxinus) are the only tree species reported as host trees of eab, while in Korea, eab also attacks a species of elm (Ulmus davidiana var.
