Native to northeast Asia, this beetle only infects dying ash trees in its home range. [8] Emerald ash borer populations can spread between 2.5 to 20 km (1.6 to 12.4 mi) per year. The emerald ash borer (EAB) is a non-native, invasive insect that was first discovered in North America in 2002 in Michigan. 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. [10] Ash susceptibility can vary depending on the attractiveness of chemical volatiles to adults, or the ability of larvae to detoxify phenolic compounds. [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. By feeding, larvae create long serpentine galleries. It’s in every state east of that line except for Mississippi and Florida. 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. [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. They add life to the forest and actually perform helpful biological processes for us. The emerald ash borer (EAB), Agrilus planipennis Fairmaire, is native to China, Korea, Japan, Mongolia, Russia, and Taiwan. [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. Modest though the response was, woodpeckers and nuthatches may be the ash trees’ best hope. Trees are killed by the tunneling of the larvae under the tree's bark. [8][7] After hatching, larvae chew through the bark to the inner phloem, cambium, and outer xylem where they feed and develop. 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. [32][33] Some urban areas such as Minneapolis have large amounts of ash with slightly more than 20% of their urban forest as ash. The search for effective detection and monitoring tools for EAB has now entered its second decade. In 2013, the emerald ash borer was found in Granville, Person, Vance, and Warren counties in North Carolina. Emerald ash borer is a species native to parts of eastern Asia that was accidentally introduced into North America, probably sometime in the 1990s. 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. 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. Many of these lingering ashes were found to have unusual phenotypes that may result in increased resistance. The emerald ash borer ( Agrilus planipennis) is a destructive wood-boring pest of ash trees ( Fraxinus spp.). Kentucky Extension specialists suggest selecting uncommon species to replace removed ashes in the landscape. [19] In China, it infests native F. chinensis, F. mandshurica, and F. rhynchophylla; in Japan it also infests F. japonica and F. [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. 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]. [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. [4] Adults beetles of other species can often be misidentified by the public. Its western range has reached South Dakota in the north down to … 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. It is not native to the United States and was first found in the U.S. near Detroit, Michigan in 2002. 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). 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. Distribution: Preliminary results were reported in Mastro and Reardon (2004 and 2005).  In summary our feeding trials found that eab most often preferred ash foliage over the non-ash species we tested, however, some feeding did occur on some non-ash species with measurable amounts occurring on fringetree, lilac, and privet.  We plan to publish the final results of this study in a refereed journal. 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. Results from this study will allow us to learn if other tree species besides ash may be threatened by eab in North America. Emerald ash borer, a beetle native to northeast Asia, was first detected in Michigan in 2002. [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. It’s in every state east of that line except for Mississippi and Florida. Volunteers catch the wasps as they return to their burrows carrying the beetles to determine whether emerald ash borer is present. Fully mature fourth-instar larvae are 26 to 32 millimeters (1.0 to 1.3 in) long. [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. The females of these wasps hunt other jewel beetles and emerald ash borer if it is present. Dinotefuran and imidacloprid are systemic (i.e., incorporated into the tree) and remain effective for one to three years depending on the product. While there are thousands of wood boring beetles in the world, most cause no problems at all. [8] These traps can also have volatile pheromones applied to them that attract primarily males. It’s in every state east of that line except for Mississippi and Florida. Northern Research Station Damage from emerald ash borer can continue to increase over time even with insecticide applications. 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. [30][31], Emerald ash borer threatens the entire North American genus Fraxinus. Outside its native range, it is an invasive species and is highly destructive to ash trees native to Europe and North America. Emerald ash borer (eab) is native to China, Japan, Korea, Mongolia, eastern Russia, and Taiwan. 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. 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. [34], In areas where emerald ash borer has not yet been detected, surveys are used to monitor for new infestations. Hannah, J. Wright State researcher finds emerald ash borer may have spread to different tree. University of Kentucky scientists suggest choosing monotypic species such as the pawpaw, yellowwood, Franklin tree, Kentucky coffeetree, Osage orange, sourwood, and baldcypress. In areas where emerald ash borer is non-native and invasive, quarantines, infested tree removal, insecticides, and biological control are used to reduce damage to ash trees. Emerald ash borer, a beetle native to northeast Asia, was first detected in Michigan in 2002. [7] This two-year life cycle is more common in cool climates, such as European Russia.[10]. [9] A typical female can live around six weeks and lay approximately 40–70 eggs, but females that live longer can lay up to 200 eggs. [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. [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. [27] Many of the specialized predators and parasitoids that suppressed emerald ash borer in Asia were not present in North America. 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. Mastro, V., and R. Reardon (Comps. You may obtain a free PDF reader from Adobe. Science theme: Forest Disturbance Processes, Science Topic: Invasive Species - Emerald Ash Borer, Forest Service Home | USDA.gov | recreation.gov Birds such as woodpeckers feed on emerald ash borer larva, although the adult beetles have not been used by any American fauna as food. 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. Urban ash are typically replaced with non-ash species such as maple, oak, or linden to limit food sources. [8], Eggs are deposited between bark crevices, flakes, or cracks and hatch about two weeks later. 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. "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". Mastro, V., and R. Reardon (Comps. [40] Ash trees are primarily treated by direct injection into the tree or soil drench. The emerald ash borer is a pest of ash trees native to Asia. White ash is also killed rapidly but usually only after all green and black ash trees are eliminated. 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. 2017 note that the … Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, insecticides, and biological control. [12] Emerald ash borer kills young trees several years before reaching their seeding age of 10 years. Host Range of Emerald Ash Borer. [9][21], Adults prefer to lay eggs on open grown or stressed ash but readily lay eggs on healthy trees amongst other tree species. [10] Both males and females use leaf volatiles and sesquiterpenes in the bark to locate hosts. Its western range has reached South Dakota in the north down to Texas in the south. 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. EAB utilize ash (Fraxinus spp.) Elytra are typically a darker green, but can also have copper hues. [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. [30][31] Other means will be used instead, especially #Biological controls. Madison, WI 53726 USDA Forest Service publication FHTET-2004-02. Effects and Impacts . In 2002, the beetle was detected for the first time in North America in the vicinity of Detroit, Michigan, and later in Windsor, Ontario. [9] Damage occurs in infested trees by larval feeding. The emerald ash borer (EAB) is an invasive species that is predicted to reach Portland in the next 5-10 years. Emerald ash borer, a beetle native to northeast Asia, was first detected in Michigan in 2002. The stressed tree attracts egg-laying females in the spring, and trees can be debarked in the fall to search for larvae. 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] Insecticide treatments are not feasible for large forested areas outside of urban areas. For a better understanding of the EAB life cycle, watch the video Cycle of Destruction(link is external). 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. [10], North American predators and parasitoids can occasionally cause high emerald ash borer mortality, but generally offer only limited control. October 9, 2014 In fact, Cipollini et al. The adults feed on the foliage of ash tress and the larvae tunnel and feed on the underside of the bark. EAB emerges in late spring, flying from June to August. [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. [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's native range includes parts of China, Korea, Japan, Taiwan, as well as small areas of Russia and Mongolia. 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. 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. Favoring instead a diversity in species helps keep urban forests healthy. Aside from their higher tannin content, Asian ashes also employ natural defenses to repel, trap, and kill emerald ash borer larvae. 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). [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. 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.). Immature larvae can overwinter in their larval gallery, but can require an additional summer of feeding before overwintering again and emerging as adults the following spring. [25][26], Green ash and black ash trees are preferred by emerald ash borer. [9] These J-shaped larvae shorten into prepupae and develop into pupae and adults the following spring. [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 (eab) is native to China, Japan, Korea, Mongolia, eastern Russia, and Taiwan. [11][10], The beetle is invasive in North America where it has a core population in Michigan and surrounding states and provinces.

Parasitism by parasitoids such as Atanycolus cappaerti can be high, but overall such control is generally low. EAB only attacks ash trees in the genus Fraxinus (so mountain ash are not susceptible). In Canada, emerald ash borer has been detected throughout southwes… 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. While most Asian ashes have evolved this defense, it is absent from American species other than blue ash. 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 Since then, it has killed millions of ash trees and caused thousands more to be removed to slow its spread. This strategy saves money as it would cost $10.7 billion in urban areas of 25 states over 10 years, while removing and replacing all ash trees in these same areas at once would cost $25 billion.
