Pine Bark Beetles. Pine bark beetles are a type of burrowing insect that can severely damage your pine trees. In outbreak years, their activities can be extremely disruptive to forest management practices aimed at wood and fiber production. The Southern Pine Bark Beetle feeding attracts other beetles. The issue of beetles, the changing forests of the western United States and Canada, as well as the changing landscape of Rocky Mountain National Park are reminders to us all of nature's ability to change beyond human control. Most species of bark beetles live in dead, weakened, or dying hosts. Mountain pine beetles affect pine trees by laying eggs under the bark. But there’s a potential for some devastating consequences. There are some beetles out there that go after arborvitae, cypress, elm, fruit, larch and redwood trees. They can be rusty-brown or black and are only about 1/4 inch long, about the size of a pencil point. “It’s a good question whether they, or any conifer-nesting bird, can outpace the spread of the beetles once they get going,” says bird field guide author Kenn Kaufman. Mountain pine beetle, spruce beetle and southern pine beetle are examples of bark beetles with the capacity for irruptive population growth. Damage or stress can result from soil compaction, surface grade changes, or bark injury by vehi-cles or heavy equipment. “If we think about the Western forest being the water tower of the West, the spruce-fir zone is really the bulk of that water tower,” says Jeff Lukas, a climate researcher with the Western Water Assessment. Only the southern pine beetle is known to attack healthy trees. Several species, such as the mountain pine beetle (Dendroctonus ponderosae), attack and kill live trees. However, numerous species of pines, and all pines found in Colorado are susceptible when beetle populations explode, including ornamental pines. If you are in a region where activity is high, inspect your trees every couple of months to try and identify if any get activity. Damage begins with Southern Pine Bark Beetles attacking the top of the trees. “Bark beetles, I like to call them first responders, because they are so sensitive to change,” says Diana Six, a forest entomologist at the University of Montana in Missoula. Periodic outbreaks of native bark beetles have occurred throughout the history of the park. For instance, the whitebark pine, with its especially large and nutritious seeds, is a favorite meal for grizzly bears fattening up before hibernation. A forester in Poland's Bialowieza Forest points to larvae of spruce bark beetles. In outbreak years, their activities can be extremely disruptive to forest management practices aimed at wood and fiber production. Beetle epidemics may also threaten water resources. You will notice yellowing then dead branches in the tops of your pines. Julie McConnell . Of course, during an epidemic episode, the amount of economic and timber loss is greatly increased. But with the scale of devastation today, many forests may never return to their former glory. More about Cheryl Katz →, Never miss a feature! Bark beetles are a natural part of the conifer forest life cycle, regularly flaring and fading like fireworks. Southern pine bark beetles cause more damage to southern pine timber than any other forest insect in Alabama. Each outbreak of the beetle will usually last between three and five years. • Take the southern pine beetle, which until recently was restricted to its native habitat in Central America and the southeastern U.S., because its larvae die when cold winter nights drop bark temperatures below 14 degrees F. The latitude of that lethal chilling limit has been creeping northward by about 40 miles a decade since 1980, the new study by Columbia University researchers finds. Craig Kohlruss Show More Show Less 2 of 12 The paths carved by adult and larvae bark beetles (called galleries) can be seen after the bark is shaved off an affected pine … G. Keith Douce, Professor of Entomology, The University of Georgia. These insects are small, brown and often dificult to see since most of their life is spent under the bark. Pine sawyers are among our most spectacular beetles. FOOTAGE. They strike quietly and their damage will quickly kill infected trees. Trees have also been weakened by a prolonged period of low precipitation. On average, the state loses 60,000 pine trees a year during a southern pine bark beetle outbreak that totals approximately $800,000 in economic loss. Normally, infestations last for a few years until the beetles kill all their host trees or a cold spell kills the beetles. As the same time, we have found it helpful to explore these forests to see all of the young new trees starting to grow. Through winter, the Information Office is open 8:00 am–4:30 pm Mon–Fri. In parts of California’s southern Sierra Nevada, beetles have killed nearly every low-elevation ponderosa pine. Pine Beetle Biology and Life Cycle. Shipping and handling. Woodpecker damage, where the birds have stripped portions of the bark from infested trees in search of larvae, leaving accumulations of bark at the base of trees is often an indicator of bark beetle presence. A version of this article first appeared in The Panama City News Herald (NewsHerald.com) on … Mountain pine beetles (Dendroctonus ponderosae; MPB) are native Colorado bark beetles that predominately infest ponderosa pine (Pinus ponderosa), lodgepole pine (P. contorta), and limber pine (P. flexilis). “I do think we’ll see some conifer forests transition to oak woodlands,” says  Fettig. Exit holes on the bark surface may be seen after the adult … Similar Images . Some temporary closures may occur until hazards are mitigated. “Some will transition to shrublands or grasslands.” Large pines and spruce may give way to smaller, scrubbier fir. There are 600 different species of bark beetles in the United States. Practice maintenance of your trees with pruning and mulching to prevent reinfestation. And from Europe to Siberia, bark beetle outbreaks are erupting with increasing frequency in woodlands weakened by rising heat and drought. Southern pine beetle (SPB) is a bark beetle that infests pine trees. Though bark beetles cause a substantial loss of trees, they are recognized as part of "natural conditions." As hazard trees are removed, material is consolidated for utilization in park trails or construction projects. And in hot, dry conditions, essentially any forest can burn. Conifer Bark Beetle Facts Black Turpentine Beetle Damage and Signs of Infestation Prevention/Management Southern pine beetle Ips or Engraver Beetle Bark Beetle Facts Bark beetles emit a chemical signal, or aggregation pheromone, which attracts more bark beetles to the tree under attack. 1. Pine bark beetles are the most destructive insects of pines in Georgia. 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.Its range extends from New Jersey to Florida to Texas to Illinois. Rocky Mountain National Park is just one relatively small area where trees are dying from the beetle epidemic. UF/IFAS. But today’s changing climate is stressing trees and making them more vulnerable to invading beetles at the same that it’s making the beetles more potent. Alias: Mountain Pine Beetle, or Pine Borer. Warming winters could push the beetles north into Canada’s boreal forest within 60 years, climate scientists say. witasek.com .
