April Flowers for redOrbit.com - Your Universe Online An infestation of bark beetles is killing trees in the mountains across the western US. The beetles all reproduce in the inner bark of the trees, though they kill the trees in different ways. For example, the mountain pine beetle attacks and kills live trees, while other species live in dead, weakened or dying trees. In fact, more than 3.4 million acres of pine trees in Colorado alone have fallen to the mountain pine beetle....

Slippery Bark Helps Protect Trees From Pine Beetle Attack
2013-12-23 13:45:28

University of Colorado Boulder Trees with smoother bark are better at repelling attacks by mountain pine beetles, which have difficulty gripping the slippery surface, according to a new study by the University of Colorado Boulder. The findings, published online in the journal Functional Ecology, may help land managers make decisions about which trees to cull and which to keep in order to best protect forested properties against pine beetle infestation. The current mountain pine...

Bait Research Focused On Outsmarting Destructive Mountain Pine Beetle
2013-11-15 13:41:44

University of Alberta University of Alberta researchers are closing in on finding an effective bait to get ahead of the destructive spread of mountain pine beetle, which is now killing not only lodgepole pine forests, but jack pine. Nadir Erbilgin, Associate Professor and Canada Research Chair in Forest Entomology in the University of Alberta Department of Renewable Resources, has been investigating pheromones emitted by the pest in North America's lodgepole and jack pine forests....

Treasure Trove Of Jewel-like Beetles Discovered
2013-10-15 12:05:26

Pensoft Publishers The bottomless pit of insect biodiversity has yielded a treasure trove of new species of jewel-like clown beetles. In a paper published today in the journal ZooKeys, Michael Caterino and Alexey Tishechkin of the Santa Barbara Museum of Natural History describe 85 new species in the genus Baconia, renowned for their brilliant coloration and bizarrely flattened body forms. The new species bring the genus up to 116 total species. The new species, mainly from North and...

Climate Change Produces Complicated Consequences For North America's Forests
2013-10-15 11:35:58

Dartmouth College Dartmouth-led study is the most comprehensive review of warming's impacts on forest pests, diseases Climate change affects forests across North America – in some cases permitting insect outbreaks, plant diseases, wildfires and other problems -- but Dartmouth researchers say warmer temperatures are also making many forests grow faster and some less susceptible to pests, which could boost forest health and acreage, timber harvests, carbon storage, water recycling and...

Massive Spruce Beetle Outbreak In Colorado Tied To Drought
2013-10-10 13:03:38

University of Colorado Boulder A new University of Colorado Boulder study indicates drought high in the northern Colorado mountains is the primary trigger of a massive spruce beetle outbreak that is tied to long-term changes in sea-surface temperatures from the Northern Atlantic Ocean, a trend that is expected to continue for decades. The new study is important because it shows that drought is a better predictor of spruce beetle outbreaks in northern Colorado than temperature alone,...

Twenty researchers – more than half of them Simon Fraser University graduates and/or faculty – could become eastern Canada´s knights in shining white lab coats. A paper detailing their newly created sequencing of the mountain pine beetle´s (MPB) genome will be gold in the hands of scientists trying to stem the beetle´s invasion into eastern forests. The journal Genome Biology has published the paper. “We know a lot about how beetle infestations can...

Mountain Pine Beetle Genome Sequenced
2013-03-27 15:42:48

BioMed Central The sequencing and assembly of the genome of the mountain pine beetle, Dendroctonus ponderosae, is published online this week in Genome Biology. The species is native to North America, where it is currently wreaking havoc in an area of forest ten times larger than previous outbreaks. This paper determines genes that may be involved in colonizing the trees, such as enzymes for degrading plant cell walls, and identifies potential sex chromosomes in the beetle. D. ponderosae...

Trees and the insects that eat them wage constant war. Insects burrow and munch; trees deploy lethal and disruptive defenses in the form of chemicals. But in a warming world, where temperatures and seasonal change are in flux, the tide of battle may be shifting in some insects' favor, according to a new study. In a report published today (Dec. 31, 2012) in the Proceedings of the National Academy of Sciences, a team of scientists from the University of Wisconsin-Madison reports a rising...

A recent report analyzing a range of published studies on the impact of bark beetles on trees in the U.S. and Canada provides a more complete picture of the effect of this destructive insect on wildfires. Previously published studies reported a wide variety of–and often contradictory–conclusions about the bark beetles' effect on fuels and wildfire. A team of researchers from the USDA Forest Service's Pacific Southwest Research and Pacific Northwest Research stations and the...
