Southern pine beetles are the most destructive forest insects in South Carolina. Everyone in the forestry community is painfully aware of the severe southern pine beetle outbreak Tennessee has experienced over the last few years. The pine beetle ranks with the bol weevil as a legendary scourge of the region, even though the beetle is no larger than a gnat. Pine Needle Scale. A recent historical review estimated that SPB caused $900 million of damage to pine forests from 1960 through 1990 (Price et a1. Mountain pine beetle (MPB) is an insect native to the forests of western North America and is also known as the Black Hills beetle or the Rocky Mountain pine beetle. There are several overlapping generations in Kentucky each year. If mountain pine beetle reaches Ontario, it could have significant impacts on forestry jobs, which many communities in northern regions rely on. MPB primarily develop in pines such as lodgepole, ponderosa, Scotch and limber pines, and less commonly affect bristlecone and piñon pines. Accessibility to the infestation, value of infested host material, markets, and management constraints associated with forest ownership and management objectives generally dictate which procedure is used. This kills the beetle and saves the tree. Adapted for eXtension.org by Thomas DeGomez, University of Arizona. Emphasis was placed on chemical control, especially after the development of chlorinated hydrocarbon pesticides such as DDT, BHC, and lindane. Southern pine beetles, which are each about the size of a grain of rice, tend to hunker down during winter. Then came spruce beetles, which have targeted high-elevation Engelmann spruce, spreading from New Mexico into Colorado and beyond. The mountain pine beetle Dendroctonus ponderosae, southern pine beetle Dendroctonus frontalis, and their near relatives are major pests of conifer forests in North America. Description: Adults are reddish-brown to black, one-eighth of an inch long, and stoutly cylindrical in shape. The mountain pine beetle (MPB) is a small insect, native to western North America, including the Black Hills. The southern pine beetle (SPB), Dendroctonus frontalis, is a minute (3 mm), invasive insect that is native to southeastern states and is the most destructive insect pest of their forests. The SPB may subsist by killing decrepit trees like those struck by lightning. Bark that is affected by Southern pine beetles needs to be removed immediately. Bark beetles range from Canada to Mexico and can be found at elevations from sea level to 11,000 feet. When the mountain pine beetle began blazing a path across forests in British Columbia and Alberta, nobody could have imagined the extent of the damage to come. State forestry organizations hired forest protection specialists, and universities and colleges began to teach courses about protection of forests from fire, insects, and disease. The southern Appalachian assessment terrestrial technical report. All told, the beetles felled 730 million cubic meters of pine between 2000 and 2015 in British Columbia, Canada’s largest exporter of timber to the U.S. housing market. But late summer droughts and severe winter snow and ice in 1998 and 1999 put extra stress on many trees. Can anyone help me? U.S. Department of Agriculture, Forest Service 1999, courtesy of the Forest Encyclopedia Network. Large areas are often killed before land managers are aware of the beetles’ presence. 50 species of exotic bark beetles have established in the continental United States and Canada (Haack 2001). National Genomics Center for Wildlife & Fish Conservation, research publications about the southern pine beetle, Identifying & Preventing Invasive Species Threats, Controlling & Managing Existing Invasive Species, Restoring & Rehabilitating Impacted Ecosystems. Today’s forests are generally denser and older, while at the same time urbanization and land use priorities, such as recreation and protection of water resources, have increased their value. Outbreaks in Tennessee, North Carolina, South Carolina, Virginia, and Georgia were recorded as early as the late 1700s and early 1800s. Pine trees originate in the northern hemisphere, but are also commonly available in the southern hemisphere's temperate and subtropical regions. The five most common southern pine bark beetle species include three in the genus Ips: the sixspined ips, Ips calligraphus (Germar); the eastern fivespined ips, Ips grandicollis (Eichhoff); and the small southern pine engraver, Ips avulsus (Eichhoff); and two species of Dendroctonus: the southern pine beetle, Dendroctonus frontalis Zimmer… Due to limited historical records, they have not previously been recorded on the northeastern slopes of the Rocky Mountains. They are indigenous, but populations are cyclic. Scientists warn that some forest ecosystems may never recover. Based on the data collected since 1960, over 36.6 million cords of pine pulp and saw timber, worth more than $901 million was destroyed. Its range extends from New Jersey to Florida to Texas to Illinois. The first outbreak on record was reported by several writers in the late 1700’s and early 1800’s. Until the late 1940s, little was done in the South to control forest pests. The greatest recorded damage was in 1995-96 when $125 million worth of timber was lost to the beetle. State and federal agencies, as well as universities, conducted research on forest pests. 2015-41595-24254 from the USDA National Institute of Food and Agriculture. Over the past few decades, the mountain pine beetle has devastated a fifth of all Colorado forestland. With other pine bark beetles, trees typically die in a patchy or scattered pattern. The southern pine beetle (Dendroctonus frontalis Zimmerman) is one of the most widespread and destructive pine insect pests.Loblolly, shortleaf, pitch, pond, and Virginia pines are the favored host tree species. The mountain pine beetle is a naturally occurring insect of the Rocky Mountain ecosystem. Pine bark beetles are frequent pests of stressed pines, Pinus spp., in the southern United States. The mountain pine beetle begins attacking most pine species on the lower 15 feet of the trunk. Introduction. Tennessee’s southern pine beetle population gradually began to build in 1998 and killed approximately 350,000 acres and $358 million of pine in the succeeding years. French Common name: Grand hylésine des pins Scientific name: Tomicus piniperda (L.) Order: Coleoptera Family: Curculionidae The pine shoot beetle (Tomicus piniperda L.; PSB) is native to Europe, North Africa and Asia.It is believed that it was first introduced to North America on ships transporting lumber from Europe, and was first detected in 1992 in the state of Ohio. Healthy trees either ward off or survive pine beetles. SPB is native to the southeastern United States but has been expanding up the Eastern Seaboard in recent years. Since it was reported in east Tennessee, coastal plain North Carolina, South Carolina, Georgia, and piedmont North Carolina, the outbreak was probably … The larvae of the sawfly feeds on the old growth needles of pine trees. The southern pine beetle (SPB), Dendroctonus frontalisZimmermann, is the most destructive insect pest of pine in the southern United States. Prediction of SPB damage is accomplished through annual monitoring of population levels with traps, and the identification of forests that are most likely to be attacked. Beetles infested most of east Tennessee and portions of middle and southwest Tennessee. Periodic outbreaks commonly recur in fairly well-defined areas. Southern Pine Beetle in the Southern Appalachians. For more information on the biology, ecology and management of the southern pine beetle, as well as numerous other forest insects, diseases and plants, please contact Doug Streett, Project Leader of the Insects, Diseases, and Invasive Plants (IDIP) Research Work Unit in Pineville, LA or visit the IDIP website. The book catalyzed the environmental movement in the United States during the 1960s and ’70s. 1992). Epidemiology and Infestation of Southern Pine Beetle, Characteristics of Pine Stands Susceptible to Southern Pine Beetle, Aerial Survey and Detection of Southern Pine Beetle, Using Verbenone to Control Southern Pine Beetle, Biological Controls of Southern Pine Beetle. The final rule will be effective 30 days after publication in the Federal Register on October 1, 2020 or on Nov. 2, 2020. However, at outbreak levels, even healthy, resistant trees are killed. Infestations are often caused by extended droughts, flooding, lightning strikes, and man caused disturbances. Even prior to the time the southern pine beetle was first described by Zimmermann in 1868, pine mortality described by early writers may be attributed to the beetle. Through the 1950s, ’60s, and ’70s, forest management was commodity or wood product driven and damage control of forest pests was highly desired. In the late 1990s, after several relatively warm winters, a massive outbreak resulted in the loss of millions of hectares of pine forest in British Columbia over the next 15 years. It is particularly problematic for pine trees during the middle of May. Price, T. 1994. For the study, the researchers selected eight 12 to 15-acre study sites in pine-hardwood ecosystems where a large number of the pines had been killed by southern pine beetle. In Northern Ontario, the $11.9 billion forestry industry, which supports more than 55,000 jobs, faces the risks of invasive pests such as the mountain pine beetle. The southern pine beetle (Dendroctonus frontalis Zimmermann) is a serious pest of pines in the southern United States, Mexico, and Central America. It has a hard black exoskeleton, and measures approximately 5 millimetres ( ⁄4 in), about the size of a grain of rice. Past experience has shown silvicultural practices such as thinning un-infested stands and removing infested trees in the early winter to reduce overwintering brood may be successful in lowering SPB populations. The European pine sawfly originates in Europe as its name indicates. Three complimentary phases of forest management are used to reduce losses to the SPB: prevention of attacks, prediction of where outbreaks will occur, and suppression of populations that have reached pest status. APHIS, in consultation with the National Plant Board, considers pine shoot beetle to be a minor pest that can be controlled locally, given its slow spread and the minimal damage it causes. Native bark beetles pose serious threats to forests and can exacerbate additional disturbance events (Covington and Moore 1994). Beetle larvae will then spend the winter feeding under the bark where they feed on the tree’s circulatory system. Mountain pine beetle (MPB) is an insect native to the forests of western North America and is also known as the Black Hills beetle or the Rocky Mountain pine beetle. Southern pine beetle (SPB) is a bark beetle that infests pine trees. There are various pests that could cause destruction to pine trees, and eventually kill them. Mountain pine beetle adults will tunnel into a tree where they lay their eggs. In addition, human safety and property are threatened by SPB-killed trees, which may be susceptible to fire and whose removal costs usually exceed the tree's value. It is particularly destructive in overmature and overcrowded stands. The SPB sometimes exists at low (endemic) population levels where it can be scarcely found, and other times at high, epidemic levels, where it causes rapid, unpredictable and substantial damage to forests. The galleries created by both the adult and their offspring can effectively girdle a tree, causing it’s death. This insect is native to the southeastern United States but has been expanding its … The mountain pine beetle is a naturally occurring insect of the Rocky Mountain ecosystem. For more on History of Southern Pine Beetle: This work is supported by New Technologies for Agriculture Extension grant no. Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. Pine beetles of all kinds – including the Western, Southern and mountain pine beetle – attack weak trees. Pine needle scale is an insect and major pest for ornamental pine trees. It is especially damaging to stands of poor vigor. The beetle occurs from Pennsylvania to Texas and from New Mexico and Arizona to Honduras (fig. References cited: There are four methods used in direct suppression of southern pine beetle: salvage removal, cut-and-leave, pile-and-burn, and chemical insecticides (Swain and Remion, 1981). Rachel Carson’s book, “Silent Spring,” decried the existing pattern of pesticide use, calling instead for a more careful use of these chemicals. Southern pine beetles are 1/8 inch long and have cylindrical, reddish-brown to black bodies. The last widespread outbreak occurred in the early 2000's and resulted in an estimated $1.5 billion dollars of economic damage. The small beetles will mass together and attack a tree as one coordinated force, overcoming the tree’s defenses and ability to “pitch out” the attacking beetles. Southern pine beetle forest infestation, courtesy USDA Forest Service, Bugwood.org. This aggressive tree killer is a native insect that lives predominantly in the inner bark of pine trees. Decades of fire suppression have created large tracts of older pine forest that provide a highway for beetle expansion. The SPB causes significant and rapid economic losses in all forest types, including traditional forests, urban forests, watersheds and viewsheds, and negatively impacts habitat for endangered species and recreational areas. Atlanta: U.S. Department of Agriculture, Forest Service, Southern Region. Photo: Ronald F. Billings, Texas Forest Service, Bugwood.org . In: C. Ferguson and P. Bowman. Native pines will rise once again on town lands where the trees had been devastated by the southern pine beetle, a pest that is having less and less of … Loblolly, shortleaf, pitch, pond, and Virginia pines are the favored host tree species. In the southern Appalachians, shortleaf, Virginia, pitch, table mountain, and eastern white pine are attacked (Price 1994). Threats to Forest Health in the Southern Appalachians. The SPB must kill its host pines to reproduce, and attacks trees en masse. Historically, D. frontalis has been distributed primarily in the pine forest regions of the southern USA (Alabama, Arkansas, Delaware, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia). We know that mountain pine beetle is a naturally occurring insect found in pine forests in the southern Rocky Mountains and in areas west of the Continental Divide. Southern Pine Beetle also carry, and introduce into trees, blue-stain fungi. Bark beetles range from Canada to Mexico and can be found at elevations from sea level to 11,000 feet. During this era, control of forest pests required intensive labor and, in many cases, was perceived by many people as being damaging to the environment as well as injurious to the people who applied the treatments. Southern pine beetles introduce the blue stain fungus that plugs up the water carrying vessels inside the tree. Their larvae are white and approximately the size of a rice grain. Image Credit: Elizabeth Benton / University of Georgia-Warnell There are more than 13 million acres of timberland in South Carolina comprising about … They can occur from the ground level to high in the canopy of the tree. Mountain pine beetle is an insect, native to western North America, where its main host is lodgepole pine. The southern pine beetle (SPB) kills pines by boring under the bark and destroying the cambium layer of the tree. They're killing an unprecedented number of trees. 1996. SPB is native to the southeastern United States but has been expanding up the Eastern Seaboard in … The beetles are native to Central America and the southeastern U.S., but they’ve increasingly been spotted in the Northeast over the past decade, with significant outbreaks in … Find research publications about the southern pine beetle on Treesearch. Since then it has launched a full attack on the invasion of North America. MPB primarily develop in pines such as lodgepole, ponderosa, Scotch and limber pines, and less commonly affect bristlecone and piñon pines. The beetle is small, only 2-4 mm in length, about the size of a grain of rice, and is red-brown to black in color. It has also been reported in Delaware, Pennsylvania, Ohio, New Jersey, Indiana, Illinois, and Missouri (St. George and Beal, 1929). Trees are … The five most common southern pine bark beetle species include three in the genus Ips: the sixspined ips, Ips calligraphus (Germar); the eastern fivespined ips, Ips grandicollis (Eichhoff); and the small southern pine engraver, Ips avulsus (Eichhoff); and two species of Dendroctonus: the southern pine beetle, Dendroctonus frontalis Zimmer… Most species of pine are susceptible to attack during intense outbreaks (Figure 1).
