What kind of beetle is a pine beetle?
Jump to navigation Jump to search. The mountain pine beetle (Dendroctonus ponderosae) is a species of bark beetle native to the forests of western North America from Mexico to central British Columbia. It has a hard black exoskeleton, and measures approximately 5 mm, about the size of a grain of rice.
Why is the mountain pine beetle outbreak so bad?
Mountain pine beetle. Climate change, monocultural replanting, and a century of forest fire suppression have contributed to the size and severity of the outbreak, and the outbreak itself may, with similar infestations, have significant effects on the capability of northern forests to remove greenhouse gas (CO 2) from the atmosphere.

How do you get rid of pine beetles?
The only treatment that can be applied to the tree is preventative. This will protect the tree by killing the beetles before they infest the tree. Insecticides containing the active ingredients permethrin or carbaryl and labeled for bark beetle control, should be done by early June to protect trees from MPB.
Are there pine beetles in Alberta?
Alberta has seen the number of pine beetle infestations grow since the early 2000s. Mountain pine beetles are advancing across Alberta and finding footholds in forests so quickly they don't have time to genetically differentiate, according to a study from the University of Alberta's biological sciences department.
How do you know if you have pine beetles?
Obvious signs of infestation include white pitch tubes, running pitch, sawdust at the base of the tree, and many small emergence holes in the bark. Larvae chew curved or S-shaped galleries under the bark in the inner bark and cambium layer, and can girdle and kill the tree.
Are pine beetles harmful?
The fungus that is carried by the beetles and kills the trees causes blue staining of the sapwood at the perimeter of the tree, but it does not affect the wood's strength, nor are there any harmful human health effects.
What causes pine beetle infestation?
A number of factors—drought, tree diseases, and overcrowding—can make trees more vulnerable to beetle attacks, and in some cases bark beetles may infest weak- ened trees already doomed to die.
Are pine beetles active in the winter?
Mountain pine beetles overwinter primarily in their “worm” or “grub” stage (the larvae). During this time, they accumulate alcohols that act as an anti-freeze and provide protection from freezing.
Can you spray for pine beetles?
Carbaryl (Sevin SL and XLR and others) and Permethrin (Astro, Dragnet and others) and bifenthrin (Onyx) are registered for use for preventatively spraying for pine beetle. Use only formulations of insecticides that are labeled for use to protect trees from bark beetle attack.
What does a pine beetle bite look like?
The welt may look like a raised, red patch of skin, whereas the blister produces a pocket of fluid and pus. The reaction develops on areas of skin exposed to the beetle. Pain, burning, redness, and swelling often accompany these lesions.
How fast do pine beetles spread?
The cycle takes just one year, and the newly formed beetle is off to find their next host and begin it all again. As the population of beetles grows from an outbreak to an epidemic, they spread across tens of thousands of trees and cause mass death.
Can a pine beetle hurt a tree?
Large populations of mountain pine beetles can be determined by the presence of woodpeckers, which feed on developing larvae under the bark, punching holes into thin-barked trees like the whitebark pine. Within eight to 10 months of a successful attack, the tree will fade and eventually die.
Are pine beetles invasive?
While not what we usually classify as an “invasive” species (exotic plants or animals imported far from their native range), the southern pine beetle's increasing threat to our pine woods makes it worth our attention. Adult Southern pine beetle.

Why did Alberta create the Pine Strategy?
Alberta created the Pine Strategy to address the amount of timber susceptible to mountain pine beetle and create a broad cross-section of different tree-age classes in the forest that will be more resilient to threats from destructive insects, disease and wildfire.
What is the front line of beetles?
This zone is the 'front line' of beetle infestations where government will aim its main control efforts. This area is not a 'line' at all, but rather a large area consisting of beetle populations threatening to spread along the Eastern Slopes and eastward further into the boreal forest.
What percentage of Alberta pine forests are over mature?
Alberta's pine forests are made up of an abundance of over-mature trees susceptible to insect attacks and catastrophic wildfires. About 60% of Alberta's pine forests consist of trees aged 80 years and older.

Through the Pine Strategy, prescribed fire and strategic harvesting, Alberta is encouraging a more natural diversity of tree ages that will be more resilient to threats from destructive insects, disease and wildfire.
How do beetle surveys help Alberta?
The surveys help to set beetle control priorities in Alberta by forecasting MPB populations for the coming year – they do not account for any potential long distance movement of beetles from British Columbia , Federal mountain parks or heavily infested areas of Alberta.
What is MPB in Alberta?
Each spring, Alberta conducts mountain pine beetle (MPB) mortality surveys to assess the number of pine beetle larvae that survived the previous winter. Surveyors cut core samples from trees and compare the number of dead versus live beetle larvae under the bark.

Is there an upside to the mountain pine beetle?
An Alberta biologist is refusing to be a gloomy Gus, however, and says there is an upside. "There was a significant killing of mountain pine beetle in those areas as a result of these very low temperatures," Janice Cooke at the University of Alberta told The Homestretch.
Where do mountain pine beetles live?
( Hopkins, 1902) The mountain pine beetle ( Dendroctonus ponderosae) is a species of bark beetle native to the forests of western North America from Mexico to central British Columbia. It has a hard black exoskeleton, and measures approximately 5 millimetres ( 1⁄4 in), about the size of a grain of rice.
What are the beetles that live in limber pine trees?
Mountain pine beetles inhabit ponderosa, whitebark, lodgepole, Scots, jack, and limber pine trees. Normally, these insects play an important role in the life of a forest, attacking old or weakened trees, and speeding development of a younger forest.
How to control beetles in a tree?
Management techniques include harvesting at the leading edges of what is known as "green attack", as well as other techniques that can be used to manage infestations on a smaller scale, including: 1 Pheromone baiting – is luring beetles into trees 'baited' with a synthetic hormone that mimics the scent of a female beetle. Beetles can then be contained in a single area, where they can more easily be destroyed. 2 Sanitation harvesting – is removing single infested trees to control the spread of beetle populations to other areas. 3 Snip and skid – is removing groups of infested trees scattered over a large area. 4 Controlled, or mosaic, burning – is burning an area where infested trees are concentrated, to reduce high beetle infestations in the area or to help reduce the fire hazard in an area. Controlling wildfires has significantly increased since the 1980s and '90s due to firefighting technology. 5 Fall and burn – is cutting (felling) and burning beetle-infested trees to prevent the spread of beetle populations to other areas. This is usually done in winter, to reduce the risk of starting forest fires. 6 Pesticides – Biopesticides such as chitosan have been tested for protection against the mountain pine beetle, and pesticides such as carbaryl, permethrin, and bifenthrin are used for smaller area applications.

How many stages of beetle development are there?
Beetles develop through four stages: egg, larva, pupa and adult. Except for a few days during the summer when adults emerge from brood trees and fly to attack new host trees, all life stages are spent beneath the bark.
What are the predators of mountain pine beetles?
Natural predators of the mountain pine beetle include certain birds, particularly woodpeckers, and various insects.
What does it mean when a tree is attacked by a beetle?
When the tree is first attacked, it remains green. Usually within a year of attack, the needles will have turned red. This means the tree is dying or dead , and the beetles have moved to another tree. In three to four years after the attack, very little foliage is left, so the trees appear grey.

There was an outbreak of mountain pine beetles in Western Canada in the 1970s that ended in the 1980s. In 1984 and 1985, severe cold weather came at the end of October and beginning of November, before the beetles were prepared. It slashed their populations, Carroll said.
How many beetles die in winter?
Around 70 to 80 per cent of beetles die in the winter of various causes, even in the healthiest population, Carroll added. Relying on the weather to control the beetle population just isn't practical, he added. Sticky sap protects trees from mountain pine beetles, Edmonton study suggests.
How much has Alberta spent on controlling the spread of beetles?
The government of Alberta has spent nearly half a billion dollars on controlling the spread of the beetle since 2006, Carroll said. This involves cutting down and destroying infected trees in an effort to slow their spread. Carroll said he just finished a study into whether the government has succeeded.
When do beetles metabolize antifreeze?
Come spring, the beetles metabolize the antifreeze and are more susceptible to the cold, so the timing of a cold snap is critical in decimating their populations. If December's extreme cold happened earlier in the year, or in March when the beetles are more mature, they likely wouldn't stand a chance, said Nadir Erbilgin, ...
