Latest Curculionidae Stories
Researchers from a variety of agencies and universities in the United States and Canada reported Thursday that trees throughout western North America are dying at twice the rate of 30 years ago.
Canada's 1.2 million square miles of forests have turned from being carbon-absorbing aids to the environment to carbon-emitting liabilities, scientists say. Since 1999, and especially in the last five years, the forests have shifted from being a carbon sink to a carbon source, Werner Kurz, senior research scientist at the Canadian Forest Service in Vancouver, told a Chicago Tribune correspondent. Rising global temperatures are drying out forests making them more susceptible to fires, which...
Cooperation between insects and bacteria suggests inter-species collaboration may be common in many ecosystems.
U.S. scientists say they've discovered pine beetles carry an antibiotic molecule that can destroy pathogenic fungi -- something no drugs can yet achieve.
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.
OTTAWA, ONTARIO--(Marketwire - Aug.
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.
As wildfires roar through tinder-dry forests in California, the mountain pine beetle is silently killing even more trees -- hundreds of thousands of acres of towering trees.
Lodgepole pine (Pinus contorta) is found in western North America in the upper mountains and subalpine regions of Colorado’s northern Rocky Mountains. This tree is considered to be invasive in New Zealand. This tree is also known as the shore pine, twisted pine, and contorta pine as well as black pine, scrub pine, and coast pine. The Lodgepole pine grows best between 8000 and 10,000 feet above sea level. They like to grow in well-drained, slightly acidic, sandy soils on gentle south...
A weevil is a beetle from the Curculionoidea superfamily. There are over 60,000 species in several families, mostly in the family Curculionidae (the true weevils). They are typically small, measuring less than Â¼ inch (6mm), and herbivorous. Due to the shape of their heads, weevils are commonly known as snout beetles. Weevils are destructive to crops. One example is the grain or wheat weevil (Sitophilus granarius), which damages stored grain. The boll weevil (Anthonomus grandis)...
