. [20] In Europe, Fraxinus excelsior is the main ash species colonized. 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. [15][16][17][18], In its native range, emerald ash borer is only a nuisance pest on native trees, as population densities typically do not reach levels lethal to healthy trees. This plant has no children Legal Status. Emerald ash borer (Agrilus planipennis) has already killed 25 million ash trees in Michigan and is expected to kill many more ash trees as it spreads. The Emerald Ash Borer (Agrilus planipennis) is a wood-boring beetle native to Asia that feeds and kills Ash trees (Fraxinus genus).The beetle’s larva bores through the bark into the cambium creating serpentine galleries where it feeds on the phloem, interrupting the flow of water and nutrients into the tree and eventually leading to its death. Ash species attacked by emerald ash borer include green (Fraxinus pennsylvanica), white (F. americana), black (F. nigra), and blue (F. quadrangulata), as well as horticultural cultivars of these species. [8] If detected, an area is often placed under a quarantine to prevent infested wood material from causing new infestations. Kentucky Extension specialists suggest selecting uncommon species to replace removed ashes in the landscape. Blue ash (F. quadrangulata) is less susceptible to emerald ash borer infestationsin theforest than otherspecies of NorthAmerican ash. [8] Insecticide treatments are not feasible for large forested areas outside of urban areas. 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. [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. [23][8] Further control measures are then taken within the area to slow population growth by reducing beetle numbers, preventing them from reaching reproductive maturity and dispersing, and reducing the abundance of ash trees. [9] Damage occurs in infested trees by larval feeding. Introduction . [12] In eastern Europe, a population was found in Moscow, Russia, in 2003. Mortality from native woodpeckers is variable. Threatened and Endangered Information: ... IN-Emerald Ash Borer Information (Purdue) (FRQU) MI-Recommended Alternatives to Ash Trees (FRQU) MI-Southeast Michigan RC (FRQU) Ash makes up roughly 13% of forested trees in the County. [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. Agrilus ... Fraxinus quadrangulata Blue ash ? spp., lingering ash . Blue Ash Fraxinus quadrangulata Olive family (Oleaceae) ... its population will probably decline because of an introduced insect pest, the Emerald Ash Borer (Agrilus planipennis). [27] Many of the specialized predators and parasitoids that suppressed emerald ash borer in Asia were not present in North America. 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. [8], Outside its native range, emerald ash borer is an invasive species that is highly destructive to ash trees in its introduced range. White ash is also killed rapidly but usually only after all green and black ash trees are eliminated. However, Blue Ash appears to be more resistant to this insect pest than other native ash species (Fraxinus spp. 8 pp. Blue ash, a Midwest native, is often found growing in limestone outcrops. Green and white ash are the most commonly found ash species in the Midwest with blue ash being rare. Suitability of Blue Ash (Fraxinus quadrangulata) and Green Ash (F. pennsylvanica) to Emerald Ash Borer (Agrilus planipennis) and its Larval Parasitoid Tetrastichus planipennisi. Green and white ash are the most commonly found ash species in the Midwest with blue ash being rare. 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. [8], Eggs are deposited between bark crevices, flakes, or cracks and hatch about two weeks later. 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. Blue ash trees are generally susceptible to a number of additional insect problems including ash borer, lilac borer, carpenter worm, oyster shell scale, leaf miners, fall webworms, ash sawflies and ash leaf curl aphid. Brittle branches are susceptible to damage from high winds and snow/ice. Prefers consistently moist, humusy loams, but is generally considered to be one of the best of the ashes for dry sites. In Missouri, it typically occurs in dry rocky woodlands, limestone glades and limestone bluffs in the Ozark region of the State (Steyermark). [23] It is suspected that it was introduced from overseas in shipping materials such as packing crates. Dinotefuran and imidacloprid are systemic (i.e., incorporated into the tree) and remain effective for one to three years depending on the product. [7] This two-year life cycle is more common in cool climates, such as European Russia.[10]. Easily grown in average, dry to medium wet, well-drained soils in full sun. Moderate Fraxinus angustifolia Narrow-leafed ash Yes Eurasia Yes japonica, Fraxinus nigra (Black ash), Fraxinus pennsylvanica (Red ash), [8] These traps can also have volatile pheromones applied to them that attract primarily males. 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. F. quadrangulata. Ash in Ontario ˜ere are ˚ve native species of ash in Ontario. [8][7] After hatching, larvae chew through the bark to the inner phloem, cambium, and outer xylem where they feed and develop. ), was discovered as the cause of widespread ash tree mortality in southeast Michigan and nearby Ontario. lanuginosa. Poland, T. M., and D. G. McCullough. [12] Emerald ash borer kills young trees several years before reaching their seeding age of 10 years. [8][40][41] Insecticides are typically only considered a viable option in urban areas with high value trees near an infestation. 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. [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. "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. 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. [32][33] Some urban areas such as Minneapolis have large amounts of ash with slightly more than 20% of their urban forest as ash. Abstract. Early Americans made a blue dye from the inner bark, hence the common name. (black ash), and F. quadrangulata Michx. from the emerald ash borer, Agrilus planipennis Fairemaire (Coleoptera: Buprestidae), at the community level was created in Pennsylvania in 2012.Advancements in the most recent Fraxinus systematics, taxonomy, distribution, and biogeography were reviewed. By feeding, larvae create long serpentine galleries. While other woody plants, such as mountainash and pricklyash, have “ash” in their name, they are not true [34], In areas where emerald ash borer has not yet been detected, surveys are used to monitor for new infestations. Outside its native range, it is an invasive species and is highly destructive to ash trees native to Europe and North America. Whereas otherstudies have examined adult host preferences, we compared the capacity of emerald ash borer larvae reared from emerald ash 2006. General ash decline is also a concern. [9][21], Adults prefer to lay eggs on open grown or stressed ash but readily lay eggs on healthy trees amongst other tree species. There is no observed host expansion. Major Professors: Clifford Sadof and Steve Yaninek. The stressed tree attracts egg-laying females in the spring, and trees can be debarked in the fall to search for larvae. [10] Ash susceptibility can vary depending on the attractiveness of chemical volatiles to adults, or the ability of larvae to detoxify phenolic compounds. [30][31] Other means will be used instead, especially #Biological controls. Predators and parasitoids native to North America do not sufficiently suppress emerald ash borer, so populations continue to grow. [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. A conceptual framework designed to protect and preserve ash trees (Fraxinus spp.) Adults exit the tree from D-shaped holes. Until recently, we have been telling you that blue ash, Fraxinus quadrangulata, appears to be resistant to emerald ash borer, Agrilus planipennis. Fraxinus quadrangulata Michx. Clusters of apetalous bisexual purplish flowers appear in April-May with the foliage. In 2002, the emerald ash borer (EAB), Agrilus planipennis (Coleoptera: Buprestidae), an Asian beetle that feeds on ash trees (Fraxinus spp. in North America since its accidental introduction from Asia (Poland and McCullough 2006). 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. Damage from emerald ash borer can continue to increase over time even with insecticide applications. 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. The Plants Database includes the following 22 species of Fraxinus . Emerald ash borer (EAB) (Agrilus planipennis) has killed millions of ash trees (Fraxinus. The mountain ash (Sorbus americana) is not a true ash and is not attacked by EAB. 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. In China, it infests native F. chinensis, F. mandshurica, and F. rhynchophylla; in Japan it also infests F. japonica and F. lanuginosa. 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. It has distinctive, 4-sided winged stems and gray platy bark. Fraxinus / ˈ f r æ k s ɪ n ə s /, English name ash, is a genus of flowering plants in the olive and lilac family, Oleaceae.It contains 45–65 species of usually medium to large trees, mostly deciduous, though a number of subtropical species are evergreen.The genus is widespread across … Due to susceptibility to emerald ash borer (EAB), blue ash is not recommended for planting anywhere in this region and usually requires removal and/or replacement. The females of these wasps hunt other jewel beetles and emerald ash borer if it is present. Emerald ash borer (Agrilus planipennis Fairmaire (Coleoptera: Buprestidae)) is a wood-boring beetle from Asia that was identified in July 2002 as the cause of widespread ash tree (Fraxinus spp.) [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. Emerald ash borer (EAB) (Agrilus planipennis) is a primary pest that has killed Planting new green ash trees is no longer recommended given the susceptibility of this tree to the emerald ash borer. [10] Both males and females use leaf volatiles and sesquiterpenes in the bark to locate hosts. Emerald Ash Borer: Invasion of the urban forest and the threat to North America’s ash resource. (Ash), Fraxinus americana (White ash), Fraxinus chinensis, Fraxinus chinensis var. The emerald ash borer (EAB, Agrilus planipennis Fair-maire) is threatening to decimate native ashes (Fraxinus ... Fraxinus (ash) is the only genus that EAB has attacked in North America. The emerald ash borer has killed millions of ash trees in the states of Ohio, Michigan, Illinois and Indiana! [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]. 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. 2011. 1. Fraxinus quadrangulata, commonly called blue ash, is native from Michigan south to Arkansas and Tennessee. The emerald ash borer is devastating our white and green ash trees. By far the … The blue ash ( Fraxinus quadrangulata) is a medium to large-sized tree that is usually 40 to 60 feet tall, but can attain a height of 150 feet with a trunk diameter of 3 feet. Habitat: Grows on Rocky Bluffs. While most Asian ashes have evolved this defense, it is absent from American species other than blue ash. Corky-winged young twigs are distinctively four-sided, thus giving rise to another common name of winged ash. Features odd-pinnate compound leaves, each with 7-11 lance-shaped, dark green leaflets (4-5” long). It is the only eastern ash with square twigs. Blue Ash and the Emerald Ash Borer. [8] Emerald ash borer populations can spread between 2.5 to 20 km (1.6 to 12.4 mi) per year. Emerald Ash Borer adult and larvae Agrilus planipennis Fairmaire Coleoptera: Buprestidae 15,000 known species and 450 genera in the family! Parks Canada Agency. [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. Reduced feeding pressure may allow such species to persist in the presence of EAB. Noteworthy Characteristics. 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. Fully mature fourth-instar larvae are 26 to 32 millimeters (1.0 to 1.3 in) long. 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. Host(s) CAPS-Approved Survey Method Major/Primary hosts Fraxinus spp. In its native range, emerald ash borer is only a nuisance pest on native trees, as population densities typically do not reach levels lethal to healthy trees. [19] In China, it infests native F. chinensis, F. mandshurica, and F. rhynchophylla; in Japan it also infests F. japonica and F. 2002 as the cause of widespread ash (Fraxinus spp.) ... Marsh. Predictions of ash mortality in infested areas would allow managers to plan and budget for hazard tree removal, restoration activities, and pre-emptive harvests. spp.) 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], North American predators and parasitoids can occasionally cause high emerald ash borer mortality, but generally offer only limited control. 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]. trees. (To learn how to inspect your trees for emerald as… [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. Elytra are typically a darker green, but can also have copper hues. Grayish bark on mature trees separates into irregular plates. [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. Insecticides with active ingredients such as azadirachtin, imidacloprid, emamectin benzoate, and dinotefuran are currently used. [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. [9] Young trees with bark between 1.5 millimeters (0.059 in) to 5 millimeters (0.20 in) are preferred. While EAB can feed on all American ash species so far tested, some are less favored than others and thus take less damage from the pest. Volunteers catch the wasps as they return to their burrows carrying the beetles to determine whether emerald ash borer is present. Early Americans made a blue dye from the inner bark, hence the common name. Blooming occurs throughout June; fruiting occurs early July through late August. As with white ash, the wood of blue ash is commercially used for a variety of products including tool handles and furniture.Genus name is the classical Latin name for ash trees.Specific epithet means four-angled in reference to the unique four-sided twigs. Some insecticides cannot be applied by homeowners and must be applied by licensed applicators. [30][31], Emerald ash borer threatens the entire North American genus Fraxinus. 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. 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. [4] Adults beetles of other species can often be misidentified by the public. [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. This insect has been identified in Porter and St. Joseph counties in … North American species of Ash are under severe threat by the invasion of the emerald ash borer beetle. 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. Currently, ash trees cannot be sold in Illinois. Four species of ash can be found in Onondaga County, white ash (Fraxinus americana), green ash (Fraxinus pennsylvanica), black ash (Fraxinus nigra) and blue ash (Fraxinus quadrangulata). Blue Ash (Fraxinus quadrangulata), a Wisconsin Threatened plant, is found in rich upland hardwoods, often with dolomite near the surface. Larval feeding between The leaves are 8 to 12 inches long with 7 to 11 leaflets, 3 to 5 inches long, oval or lance shaped, and finely toothed margins. Branchlets ± sharply 4-angled or even slightly winged, with flattish sides. Parasitism by parasitoids such as Atanycolus cappaerti can be high, but overall such control is generally low. [8] Males hover around trees, locate females by visual cues, and drop directly onto the female to mate. Aside from their higher tannin content, Asian ashes also employ natural defenses to repel, trap, and kill emerald ash borer larvae. [10] Larvae can also survive high heat up to 53 °C (127 °F). Detailed Assessment for the Blue Ash (Fraxinus quadrangulata) in Point Pelee National Park of Canada. To exit the tree, adults chew holes from their chamber through the bark, which leaves a characteristic D-shaped exit hole. Emerald ash borer will typically kill an ash tree within 3-5 years after infestation. [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. "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 is native to Asia. In Missouri, it typically occurs in dry rocky woodlands, limestone glades and limestone bluffs in the Ozark region of the State (Steyermark). Dorsal view of adult with elytra and wings spread. After emergence, adults feed for one week on ash leaves in the canopy before mating, but cause little defoliation in the process. 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. decline and mortality in southeastern Michigan and adjacent parts of Ontario, Canada. Emerald ash borer (Agrilus planipennis) is an invasive, wood-boring beetle that kills ash trees (Fraxinus spp.) [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. [40] Ash trees are primarily treated by direct injection into the tree or soil drench. Despite federal and state quarantine… Ash leaves are usually pinnately compound and appear opposite on the stem. Once infestation occurs, it is very difficult to eradicate this pest which feeds under the bark and bores into wood. [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. The results of subsequent studies showed that EAB was inadvertently introduced near Detroit, Michigan during the 1990s from northeast China, probably in EAB-infested solid-wood packing materials used in international trade. Favoring instead a diversity in species helps keep urban forests healthy. Fraxinus quadrangulata, commonly called blue ash, is native from Michigan south to Arkansas and Tennessee. The Garden wouldn't be the Garden without our Members, Donors and Volunteers. The species also has a small spine found at the tip of the abdomen and serrate antennae that begin at the fourth antennal segment. 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. 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. (blue ash). The Ash or Fraxinus genus of 45-65 species of mostly medium to large deciduous trees. The lilac leaf miner, ash borer and fall webworm may be minor pests on this tree. : emerald ash borer, Agrilus planipennis, Fraxinus. Fraxinus in Michigan and surrounding areas are being devastated by the emerald ash borer (Agrilus planipennis), an Asian insect first discovered in North America in southeastern Michigan in 2002. Description, biology, hosts, … The emerald ash borer (EAB) has become a serious problem in Kentucky. [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. [32] Costs for managing these trees can fall upon homeowners or local municipalities. rhynchophylla, Fraxinus japonica, Fraxinus lanuginosa, Fraxinus mandshurica, Fraxinus mandshurica var. The lilac borer is the main pest problem with blue ash. Emerald ash borer . This is an upland species that typically grows 50-75’ tall with a narrow, irregularly rounded crown. This borer now constitutes a serious threat to all species of ash in North America. Click below on a thumbnail map or name for species profiles. Winter temperatures of approximately −38 °C (−36 °F) limit range expansion.,[28][29] and overwintering emerald ash borer survive down to average temperatures of −30 °C (−22 °F) because of antifreeze chemicals in the body and insulation provided by tree bark. Eastern U.S. ... and blue ash (F. quadrangulata) are less preferred. [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. [9], Sometimes trees are girdled to act as trap trees to monitor for emerald ash borer. Parks Canada Agency, Ottawa. by eating the tissues under the bark. ˜ey are: white ash (Fraxinus americana), black ash (Fraxinus nigra), green ash (Fraxinus pennsylvanica - also called red ash), pumpkin ash (Fraxinus profunda) and blue ash (Fraxinus quadrangulata). [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. [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. Flowers give way to drooping clusters of winged samaras (to 2” long) that ripen in fall and may persist on the tree throughout winter. The native range of the emerald ash borer is temperate north-eastern Asia, which includes Russia, Mongolia, northern China, Japan, and Korea. It usually is found growing in dry or well-drained alkaline soils derived from limestone, but it can also grow in draining wet soils that are acid, with a pH range of 6.5 to 8.5. Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, insecticides, and biological control.
