emerald ash borer native range


Eggs are laid from mid-June through August. The emerald ash borer ( Agrilus planipennis) is a destructive wood-boring pest of ash trees ( Fraxinus spp.). Adult beetles average 3/8″ to 3/4″ long and 1/6″ wide. [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. [39] Previous generations created monocultures by planting ash trees in an overabundance, a factor in the extent of the devastation caused by the emerald ash borer. Robert A. Haack and Toby R. Petrice, USDA Forest Service, North Central Research Station, 1407 S. Harrison Road, East Lansing, MI 48823. p. 38 In V. Mastro and R. Reardon (compilers) Emerald Ash Borer research and technology development meeting, Port Huron Michigan, Sept 30-Oct 1, 2003. Emerald Ash Borer (EAB) was found in Boulder, CO, in September 2013. Native to northeast Asia, this beetle only infects dying ash trees in its home range. [9] Emerald ash borer has four larval instars.

The stressed tree attracts egg-laying females in the spring, and trees can be debarked in the fall to search for larvae. 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. "The biology and ecology of the emerald ash borer, "Emerald ash borer: invasion of the urban forest and the threat to North America's ash resource", "Emerald Ash Borer attacking White Fringe Tree", "Initial County EAB detections in North America", "Emerald ash borer in North America: a research and regulatory challenge". 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. EAB utilize ash (Fraxinus spp.) Blue ash is known to exhibit a higher degree of resistance to emerald ash borer, which is believed to be caused by the high tannin content in the leaves making the foliage unpalatable to the insect. 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. But another study noted that very few native or introduced insect predators or parasites prey on the emerald ash borer. [8] Quarantines can limit the transport of ash trees and products, but economic impacts are especially high for urban and residential areas because of treatment or removal costs and decreased land value from dying trees. [8] After initial infestation, all ash trees are expected to die in an area within 10 years without control measures. [9] Young trees with bark between 1.5 millimeters (0.059 in) to 5 millimeters (0.20 in) are preferred. [8][7] After hatching, larvae chew through the bark to the inner phloem, cambium, and outer xylem where they feed and develop. In 2002, the beetle was detected for the first time in North America in the vicinity of Detroit, Michigan, and later in Windsor, Ontario. The emerald ash borer is a pest of ash trees native to Asia. While there are thousands of wood boring beetles in the world, most cause no problems at all. Host range of Emerald Ash Borer. The emerald ash borer is a small wood-boring beetle in the family Buprestidae. [25][26], Green ash and black ash trees are preferred by emerald ash borer. [8] These traps can also have volatile pheromones applied to them that attract primarily males. Its western range has reached South Dakota in the north down to Texas in the south. Girdled ashes will often attempt to regenerate through stump sprouting, and there is evidence that stressed trees may also generate higher than normal seed crops as an emergency measure. Its western range has reached South Dakota in the north down to Texas in the south. Economic impacts associated with eab include the loss of valuable trees for timber production and the loss of ash from city and suburban landscapes. Since first being recorded in Michigan in 2002, the emerald ash borer has broadened its range in the United States and has killed millions of ash trees. [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. [7] This two-year life cycle is more common in cool climates, such as European Russia.[10]. It is not native to the United States and was first found in the U.S. near Detroit, Michigan in 2002. Eggs are approximately 0.6 to 1.0 millimeter (0.02 to 0.04 in) in diameter, and are initially white, but later turn reddish-brown if fertile. [23] It is suspected that it was introduced from overseas in shipping materials such as packing crates. [30][31], Emerald ash borer threatens the entire North American genus Fraxinus. ).  2005. The emerald ash borer (EAB), Agrilus planipennis Fairmaire, is native to China, Korea, Japan, Mongolia, Russia, and Taiwan. Emerald ash borer (eab) is native to China, Japan, Korea, Mongolia, eastern Russia, and Taiwan. EAB Facts: It attacks only ash trees (Fraxiinus spp.). Predators and parasitoids native to North America do not sufficiently suppress emerald ash borer, so populations continue to grow. [37] In rural areas, trees can be harvested for lumber or firewood to reduce ash stand density, but quarantines may apply for this material, especially in areas where the material could be infested.[38]. 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. October 9, 2014 To exit the tree, adults chew holes from their chamber through the bark, which leaves a characteristic D-shaped exit hole. While most Asian ashes have evolved this defense, it is absent from American species other than blue ash. Visual surveys are used to find ash trees displaying emerald ash borer damage, and traps with colors attractive to emerald ash borer, such as purple or green, are hung in trees as part of a monitoring program. 2017 note that the … Emerald ash borer, a beetle native to northeast Asia, was first detected in Michigan in 2002. Adult Beetles are metallic green and about 1/2 inch long. [2], Adult beetles are typically bright metallic green and about 8.5 millimeters (0.33 in) long and 1.6 millimeters (0.063 in) wide. It is not native to the United States and was first found in the U.S. near Detroit, Michigan in 2002. They add life to the forest and actually perform helpful biological processes for us. Mating can last 50 minutes, and females may mate with multiple males over their lifespan. Though it has not been found in Florida, there is potential for it to establish via movement of infested wood into the state and the presence of ash trees in Florida. Winter temperatures of approximately −38 Â°C (−36 Â°F) limit range expansion.,[28][29] and overwintering emerald ash borer survive down to average temperatures of −30 Â°C (−22 Â°F) because of antifreeze chemicals in the body and insulation provided by tree bark. (608) 231-9544 TTY/TDD. 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. Emerald ash borer are small, iridescent green beetles that live outside of trees during the summer months. To date, in North America, eab has been found to successfully reproduce only in species of ash. In 2013, the emerald ash borer was found in Granville, Person, Vance, and Warren counties in North Carolina. Documents above are in pdf format. Emerald ash borer, a beetle native to northeast Asia, was first detected in Michigan in 2002. EAB emerges in late spring, flying from June to August. The search for effective detection and monitoring tools for EAB has now entered its second decade. [9] Damage occurs in infested trees by larval feeding. White ash is also killed rapidly but usually only after all green and black ash trees are eliminated. [3] They leave tracks in the trees they damage below the bark that are sometimes visible. [8][40][41] Insecticides are typically only considered a viable option in urban areas with high value trees near an infestation. [7], After 400–500 accumulated degree-days above 10 Â°C (50 Â°F), adults begin to emerge from trees in late spring, and peak emergence occurs around 1,000 degree-days. [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. japonica), and in Japan it is reported to infest ash, elm, walnut (Juglans mandshurica) and wingnut (Pterocarya rhoifolia). Parasitism by parasitoids such as Atanycolus cappaerti can be high, but overall such control is generally low. The adults feed on the foliage of ash tress and the larvae tunnel and feed on the underside of the bark. For a better understanding of the EAB life cycle, watch the video Cycle of Destruction(link is external). [8] Males hover around trees, locate females by visual cues, and drop directly onto the female to mate. The rampage of the emerald ash borer is traced to the late 1990s, when it arrived from Asia in wood used in shipping pallets that showed up in Michigan. By feeding, larvae create long serpentine galleries. Emerald ash borer (eab) is native to China, Japan, Korea, Mongolia, eastern Russia, and Taiwan. Adults leave a D-shaped exit hole in the bark when they emerge in Spring. The species also has a small spine found at the tip of the abdomen and serrate antennae that begin at the fourth antennal segment. Some insecticides cannot be applied by homeowners and must be applied by licensed applicators. as an overstory component in North American forests. It has killed tens of millions of ash trees so far and threatens to kill most of the 8.7 billion ash trees throughout North America. by eating the tissues under the bark.Native to northeastern Asia, emerald ash borer (EAB) was first detected in the United States in 2002 and is thought to have been introduced from China via the wood from shipping crates. Effects and Impacts . It is native to eastern Russia, northern China, Japan, and Korea. It’s in every state east of that line except for Mississippi and Florida. [8] In both North America and Europe, the loss of ash from an ecosystem can result in increased numbers of invasive plants, changes in soil nutrients, and effects on species that feed on ash. For municipalities, removing large numbers of dead or infested trees at once is costly, so slowing down the rate at which trees die through removing known infested trees and treating trees with insecticides can allow local governments more time to plan, remove, and replace trees that would eventually die. To date, in North America, eabhas been found to succes… [10] Larvae can also survive high heat up to 53 Â°C (127 Â°F). Birds such as woodpeckers feed on emerald ash borer larva, although the adult beetles have not been used by any American fauna as food. [8], The native range of emerald ash borer in Asia was surveyed for parasitoid species that parasitize emerald ash borer and do not attack other insect species in the hope they would suppress populations when released in North America. Emerald ash borer is the only North American species of Agrilus with a bright red upper abdomen when viewed with the wings and elytra spread. [19] In China, it infests native F. chinensis, F. mandshurica, and F. rhynchophylla; in Japan it also infests F. japonica and F. The emerald ash borer (Agrilus planipennis), also known by the acronym EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash species. Its western range has reached South Dakota in the north down to Texas in the south. As an invasive pest, EAB now lives in Ontario, Ohio, Indiana, Illinois, Maryland, Pennsylvania, West Virginia, Wisconsin, Missouri, and Virginia. Past struggles with Dutch elm disease and current ones with emerald ash borer (EAB) have led the city to implement diversification plans, as well … Results from this study will allow us to learn if other tree species besides ash may be threatened by eab in North America. In fact, Cipollini et al. japonica), and in Japan it is reported to infest ash, elm, walnut (Juglans mandshurica) and wingnut (Pterocarya rhoifolia). as their primary hosts. Emerald ash borer (Agrilus planipennis) is an invasive, wood-boring beetle that kills ash trees (Fraxinus spp.) [22] Before emerald ash borer was found in North America, very little was known about the insect in its native range aside from a short description of life-history traits and taxonomic descriptions, which resulted in focused research on its biology in North America. Host Range of Emerald Ash Borer. [12] In eastern Europe, a population was found in Moscow, Russia, in 2003. Department of Natural Resources - (Agrilus planipennis) Prohibited in Michigan The Emerald Ash Borer is a bright, metallic green insect with purple abdominal segments under its wing covers. Emerald Ash Borer is a forest pest native to Asia that has killed millions of Ash trees in southwestern Ontario, and the Great Lakes States. [7] In fall, mature fourth-instars excavate chambers about 1.25 centimeters (0.49 in) into the sapwood or outer bark where they fold into a J-shape. (To learn how to inspect your trees for e… USDA Forest Service publication FHTET-2004-02. In its native range, EAB is not a very damaging insect where the ash species that grow there have evolved resistance to it and natural controls limit its injury. University of Kentucky scientists suggest choosing monotypic species such as the pawpaw, yellowwood, Franklin tree, Kentucky coffeetree, Osage orange, sourwood, and baldcypress. Furthermore, most ashes used in landscaping were produced from a handful of cultivars, resulting in low genetic diversity. [8] Every North American ash species has susceptibility to emerald ash borer, as North American species planted in China also have high mortality from infestations, but some Chinese ash species are resistant. The larvae is worm-like and live underneath the bark of ash trees. [4] Adults beetles of other species can often be misidentified by the public. [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. Researchers have examined populations of so-called "lingering ash", trees that survived ash borer attack with little or no damage, as a means of grafting or breeding new, resistant stock. Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, insecticides, and biological control. Science theme: Forest Disturbance Processes, Science Topic: Invasive Species - Emerald Ash Borer, Forest Service Home | USDA.gov | recreation.gov The emerald ash borer is a metallic green beetle that bores into ash trees feeding on tissues beneath the bark, ultimately killing the tree. [8] The insect was first identified in Canton, Michigan, in 2002, but it may have been in the U.S. since the late 1980s. Its western range has reached South Dakota in the north down to Texas in the south. [8], Government agencies in both the U.S. and Canada have utilized a native species of parasitoid wasp, Cerceris fumipennis, as a means of detecting areas to which emerald ash borer has spread. [10] Both males and females use leaf volatiles and sesquiterpenes in the bark to locate hosts. Trees are killed by the tunneling of the larvae under the tree's bark. [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. However, emerald ash borer was found attacking and developing in white fringe tree (Chionanthus virginicus) in Ohio and has most recently been confirmed as able to feed and develop successfully on cultivated olive (Olea europaea). [30][31] Other means will be used instead, especially #Biological controls. [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. Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. [10], North American predators and parasitoids can occasionally cause high emerald ash borer mortality, but generally offer only limited control. Aside from their higher tannin content, Asian ashes also employ natural defenses to repel, trap, and kill emerald ash borer larvae. You may obtain a free PDF reader from Adobe. [8], Eggs are deposited between bark crevices, flakes, or cracks and hatch about two weeks later. (608) 231-9318 [2] Unaware of Fairmaire's description, a separate description naming the species as Agrilus marcopoli was published in 1930 by Jan Obenberger. [8] Emerald ash borer populations can spread between 2.5 to 20 km (1.6 to 12.4 mi) per year. Emerald ash borer is a species native to parts of eastern Asia that was accidentally introduced into North America, probably sometime in the 1990s. [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. [8], The United States Department of Agriculture's Animal and Plant Health Inspection Service published a rule on December 14, 2020 - to take effect one month later, January 14, 2021 - ending all EAB quarantine activities in the United States due to ineffectiveness so far. 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. In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area. Since then, it has killed millions of ash trees and caused thousands more to be removed to slow its spread. Hannah, J. Wright State researcher finds emerald ash borer may have spread to different tree. The emerald ash borer (EAB) is an invasive species that is predicted to reach Portland in the next 5-10 years. "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. The emerald ash borer is an Asian species native to China, Japan, Taiwan, Korea, Mongolia and the Russian Far East. [32][33] Some urban areas such as Minneapolis have large amounts of ash with slightly more than 20% of their urban forest as ash. French priest and naturalist Armand David collected a specimen of the species during one of his trips through imperial China in the 1860s and 1870s. The native range of the emerald ash borer is temperate north-eastern Asia, which includes Russia, Mongolia, northern China, Japan, and Korea. 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. Urban ash are typically replaced with non-ash species such as maple, oak, or linden to limit food sources. It’s in every state east of that line except for Mississippi and Florida. ).  2004.  Emerald Ash Borer Research and Technology Development Meeting, Port Huron, MI, 30 Sept.-1 Oct. 2003.  U.S. Department of Agriculture, Forest Service publication FHTET-2004-02, Washington, DC. They are approximately 1/2 inch in length and can fit on the head of a penny. [12] Emerald ash borer kills young trees several years before reaching their seeding age of 10 years. 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. [44] Tetrastichus planipennisi and Oobius agrili established and have had increasing populations in Michigan since 2008; Spathius agrili has had lower establishment success in North America, which could be caused by a lack of available emerald ash borer larvae at the time of adult emergence in spring, limited cold tolerance, and better suitability to regions of North America below the 40th parallel. One study found that woodpeckers could eat an average of 44 percent of the borer larvae at a site. [34], In areas where emerald ash borer has not yet been detected, surveys are used to monitor for new infestations. Mastro, V., and R. Reardon (Comps. Favoring instead a diversity in species helps keep urban forests healthy. [32] Costs for managing these trees can fall upon homeowners or local municipalities. 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. Dinotefuran and imidacloprid are systemic (i.e., incorporated into the tree) and remain effective for one to three years depending on the product. Emerald ash borer's native range includes parts of China, Korea, Japan, Taiwan, as well as small areas of Russia and Mongolia. [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. [27] Many of the specialized predators and parasitoids that suppressed emerald ash borer in Asia were not present in North America. Volunteers catch the wasps as they return to their burrows carrying the beetles to determine whether emerald ash borer is present. EAB only attacks ash trees in the genus Fraxinus (so mountain ash are not susceptible). 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). Emerald ash borer, a beetle native to northeast Asia, was first detected in Michigan in 2002. Insecticides with active ingredients such as azadirachtin, imidacloprid, emamectin benzoate, and dinotefuran are currently used. [9] Emerald ash borer has also been found infesting white fringe tree in North America, which is a non-ash host, but it is unclear whether the trees were healthy when first infested, or were already in decline because of drought.
