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...

Scientists Turn To The Phonebook To Name 101 New Beetle Species
2013-03-28 09:33:58

April Flowers for redOrbit.com - Your Universe Online Tropical rainforests are known to harbor a high biodiversity of untold species, many of them unknown and unnamed by scientists as of yet. Insects, especially beetles, make up a large proportion of this undiscovered life on Earth. Experts in remote tropical countries' fauna such as the wilderness of New Guinea, Alexander Riedel of the Natural History Museum Karlsruhe (SMNK) and Michael Balke of the Zoological State Collection Munich...

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...

A research team involving several scientists from the University of Colorado Boulder has found an unexpected silver lining in the devastating pine beetle outbreaks ravaging the West: Such events do not harm water quality in adjacent streams as scientists had previously believed. According to CU-Boulder team member Professor William Lewis, the new study shows that smaller trees and other vegetation that survive pine beetle invasions along waterways increase their uptake of nitrate, a common...

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...

Mountain Pine Beetle Epidemic Propelled By 2001-2002 Drought
2012-11-05 14:04:12

University of Colorado Boulder Beetles then moved into wetter and higher elevations A new University of Colorado Boulder study shows for the first time that episodes of reduced precipitation in the southern Rocky Mountains, especially during the 2001-02 drought, greatly accelerated development of the mountain pine beetle epidemic. The study, the first ever to chart the evolution of the current pine beetle epidemic in the southern Rocky Mountains, compared patterns of beetle outbreak...

Monarch Butterfly's Survival Ensured By Trapping Weevils
2012-10-01 16:47:23

Ensuring the monarch butterfly's survival by saving its milkweed habitat could result from U.S. Department of Agriculture (USDA) studies initially intended to improve detection of boll weevils with pheromone traps. Charles Suh and his colleagues at the Agricultural Research Service (ARS) Areawide Pest Management Research Unit in College Station, Texas, have found a pheromone formula that is attractive to a major milkweed pest, the milkweed stem weevil. The discovery stems from research...

Waldo Canyon Fire, Colorado
2012-06-29 11:00:06

Brett Smith for redOrbit.com - Your Universe Online A conspiracy between Nature´s forces has sent walls of fire ripping through Colorado sending residents, officials, and first responders scrambling into action. One of the more devastating fires, the Waldo Canyon fire, has forced more than 32,000 people in and around Colorado´s second-most-populous city of Colorado Springs from their homes. The blaze, which began Saturday, is just 15 percent contained, according to the...

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...

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...

Lodgepole Pine, Pinus contorta
2014-04-27 08:06:16

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 ¼ 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)...
