Mountain pine beetles devastating lodgepole pine stands across the West might best be kept in check with aerial application of flakes containing a natural substance used in herbal teas that the insects release to avoid overcrowding host trees, according to a team of scientists.Findings from the U.S. Forest Service-funded study appear in the February issue of Forest Ecology and Management. The study was conducted in California and Idaho, and showed how applications of laminated flakes...

U.S scientists say pine bark beetles killing large areas of forests in the Rocky Mountains might be altering local weather patterns and air quality. The international research project is being led by scientists at the National Center for Atmospheric Research in Boulder, Colo. "Forests help control the atmosphere and there's a big difference between the impacts of a living forest and a dead forest," said NCAR scientist Alex Guenther. "With a dead forest, we may get different rainfall...

Utah researchers said bark beetles are destroying spruce trees in the Dixie National Forest. The U.S. Forest Service's Bark Beetle Technical Working Group said the bark beetle is an "agent of change" in conifer forests in the Rocky Mountain region, the Deseret Morning News reported this week. "We're talking hundreds of thousands of acres they have basically been wiped out -- pretty much the entire spruce component in the Dixie National Forest," Colleen Keyes of the Utah Division of...

By Stephen Speckman Deseret News A vicious cycle is brewing in Utah: Bark beetles are killing a lot of trees in the state. Dead trees are fuel for wildfires, which experts say contributes to global warming. And climate change is now being blamed for an increased population of bark beetles. The Dixie National Forest bears one of the most obvious signs in Utah of the mark being left by a tiny tree predator commonly known as the bark beetle, a wood-boring insect that in large enough numbers...

By Hazlehurst, John During the last 10 years, mountain pine beetles have killed more than 1.5 million acres of lodgepole pines statewide. Summit County, home to Colorado's ski industry, has been particularly hard hit. The verdant forests that once framed Breckenridge, Copper Mountain, Keystone and Beaver Creek are dying, attacked by an invading army of microscopic beetles less than an eighth of an inch in length. Tens of thousands of acres of dead or dying trees now surround...

By Christine Weeber Pesticides often have larger effects than we intend. Some of those used in responding to the mountain pine beetle infestation are no different. Carbaryl, the active ingredient in the most common sprays used to protect trees against beetles, is one of these. It is a neurotoxin that is dangerous to humans and pets through skin contact, inhalation and ingestion through food or water. And it is highly toxic to bees, stoneflies and some fish. In 2005, 12 groups representing...

By Cramer, John Scientists, economists, land managers and others will gather Thursday in Missoula to discuss the worsening infestation of bark beetles across the West. "Red Tree," a one-day public symposium, is scheduled from 9 a.m. to 5 p.m. in the University of Montana's University Center Ballroom. The symposium is free, but registration is required at 542-4300. Mountain pine beetles and other bark beetles have killed millions of acres of trees from Alaska to the Southwest in recent...

Most of Colorado's lodgepole pine trees stand to be dead within the next 5 years.  In 1996, a bark beetle infestation was detected, and last year it spread over 500,000 acres more than previous years. Federal forestry officials say that this brings the total count of affected acres to 1.5 million. This infestation mainly affects five northern counties which straddle the Continental Divide, and has recently spread to part of southern Wyoming and the Front Range. Those effected counties...

VAIL, Colo. -- The mountain views along Red Stone Road suggest early autumn, with splashes of red, orange and rusty brown dotting the green hillsides above the homes and condominiums of this Colorado resort town. But this is summer and the colors represent dead pine needles on hundreds of pine trees that have been killed by beetles. The tree mortality rate around Vail is striking, but it's even worse in other parts of the West. According to U.S. Forest Service figures compiled for The...

University of Nevada, Reno scientists have ended a decade-long controversy over the process by which bark beetles make pheromones: they manufacture their own monoterpenes "“ the fragrant substances plants produce and which are often used in perfumes. It had been thought that insects and other animals were incapable of making these substances. "The goal of our research is ultimately to control pheromone production," said Gary Blomquist, professor and chair of biochemistry and molecular...
