Beetles Contribute To Air Pollution In Forests
2012-05-25 07:05:45

Brett Smith for RedOrbit.com Activity of the bark beetle is having an impact on both air quality and climate, according to a new report from a team of American scientists published in the journal Environmental Science & Technology. Evidence of the beetle´s impact can be seen in the lodgepole pine forests of the western United States. Many of the trees there are dying or ravaged by the beetles and a faint haze of particulate matter can be seen throughout the area. Air samples...

The hordes of bark beetles that have bored their way through more than 6 billion trees in the western U.S. and British Columbia since the 1990s do more than damage and kill stately pine, spruce and other trees. A new study finds that these pests can make trees release up to 20 times more of the organic substances that foster haze and air pollution in forested areas. It appears in ACS' journal Environmental Science & Technology. Kara Huff Hartz, Gannet Hallar and colleagues explain that...

Climate change puts spruce forests at greater risk of bark beetle attacks Climate change appears to be good news for destructive bark beetles, according to a new study by Lorenzo Marini from the University of Padova in Italy, and his team. Their work, published online in Springer's Climatic Change, shows that there were more attacks by the spruce bark beetle on European Alpine spruce forests over a 16 year period, as temperatures rose and rainfall dropped. Shifts in temperature,...

Periodic outbreaks of bark beetles can cause annual losses of millions of dollars and pose serious challenges for forest managers, and the suppression of outbreaks is particularly difficult and expensive. According to T. D. Schowalter, author of a new open-access article in the Journal of Integrated Pest Management called "Ecology and Management of Bark Beetles (Coleoptera: Curculionidae: Scolytinae) in Southern Pine Forests," preventative measures are most effective in minimizing losses...

Warming temperatures appear to allow pine beetles to now breed twice a year Long thought to produce only one generation of tree-killing offspring annually, some populations of mountain pine beetles now produce two generations per year, dramatically increasing the potential for the bugs to kill lodgepole and ponderosa pine trees, University of Colorado Boulder researchers have found. Because of the extra annual generation of beetles, there could be up to 60 times as many beetles...

The southern pine beetle, Dendroctonus frontalis Zimmermann, is a chronic insect pest within pine forests in the southeastern United States. Under favorable environmental and host conditions, it is an aggressive, primary bark beetle capable of killing large acreages of pines. Its principal range stretches from east Texas and Oklahoma to the east coast and north to southern New Jersey. In "Implications of Population Phases on the Integrated Pest Management of the Southern Pine Beetle,...

North Carolina State University researchers have found that a subset of fungus-farming ambrosia beetles may be in the early stages of a global epidemic threatening a number of economically important trees, including avocados, poplars and oaks. "Only about 12 species of ambrosia beetle are creating problems so far, but there are thousands of other species in the world, many of which could be devastating to any number of tree species," says Dr. Jiri Hulcr, a postdoctoral research associate at...

Lodgepole pine, a hardy tree species that can thrive in cold temperatures and plays a key role in many western ecosystems, is already shrinking in range as a result of climate change "“ and may almost disappear from most of the Pacific Northwest by 2080, a new study concludes. Including Canada, where it is actually projected to increase in some places, lodgepole pine is expected to be able to survive in only 17 percent of its current range in the western parts of North America. The...

A new beetle-kill floor has been installed at Mi Cocina Mexican Restaurant in Littleton, Colorado. It is the first such application of beetle-kill pine flooring in a restaurant in the United States. Littleton, CO (PRWEB) December 1, 2010 A new beetle-kill floor has been installed at Mi Cocina Mexican Restaurant in Littleton, Colorado. It is the first such application of beetle-kill pine flooring in a restaurant in the United States. Information from The Beetle-kill Trade Association says,...

UBC researchers have helped developed a cheaper, faster way to compile draft genome sequences that could advance the fight against mountain pine beetle (MPB) infestation and improve cancer research. Current sequencing methods have a variety of advantages and disadvantages--including the cost involved. Dr Steven Jones and colleagues at UBC, the BC Cancer Agency and Simon Fraser University have combined cutting edge hardware with novel software to compile genome sequences at a fraction of the...
