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.
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.
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.
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.
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.
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.
Most of Coloradoâ€™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.
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.

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 â€“ 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.
