Salt Cedar Beetle Damage Widespread After Warm Summer
2012-09-28 09:24:28

Salt cedar along the waterways of the southern and eastern Panhandle is rapidly being defoliated and dying back, and one Texas A&M AgriLife Research entomologist believes he knows why. When salt cedar beetles from Uzbekistan were released in 2006 by Dr. Jerry Michels and his entomology crew in parts of Lake Meredith and the Palo Duro Canyon, it was thought they would be more prolific eaters of salt cedar than other beetle species tried before. Salt cedar displaces native vegetation...

WASHINGTON, July 31, 2012 /PRNewswire/ -- The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is asking the public to be on the lookout for the Asian longhorned beetle (ALB). August is a time of peak emergence for the devastating invasive pest and a critical time for building the public's awareness of ALB. (Logo: http://photos.prnewswire.com/prnh/20120702/CL34224LOGO) ALB was first discovered in the United States in 1996, likely arriving via wood packing...

How Western Corn Rootworm Resists Crop Rotation
2012-07-19 08:40:51

A new study answers a question that has baffled researchers for more than 15 years: How does the western corn rootworm — an insect that thrives on corn but dies on soybeans — persist in fields that alternate between corn and soybeans? The answer, researchers say, has to do with enzyme production in the rootworm gut. Their findings are described in a paper in Ecology and Evolution. Crop rotation declined in the middle of the 20th century as the use of insecticides and...

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...

New research from Lund University in Sweden reveals the value of carrying two layers of wings around. The researchers studied dung beetles and the way their protective forewings actually function. These wings do not only protect but also help the beetles to lift off from the ground — albeit at a cost. The forewings of beetles, the elytra, are hardened structures which protect the insect's flying wings and body. The function of the forewings in flight has been questioned, which is...

Beetles Contribute To Air Pollution In Forests
2012-05-25 07:05:45

Brett Smith for RedOrbit.com Activity of the bark beetle is having an impact on both air quality and climate, according to a new report from a team of American scientists published in the journal Environmental Science & Technology. Evidence of the beetle´s impact can be seen in the lodgepole pine forests of the western United States. Many of the trees there are dying or ravaged by the beetles and a faint haze of particulate matter can be seen throughout the area. Air samples...

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...

Researchers use a fire from almost 90 years ago to model the sensitivity of a natural sensor Criminal cases can often only be solved using forensics to piece together physical evidence and reconstruct what happened. Prof. Dr. Helmut Schmitz from the Institute of Zoology at the University of Bonn and Dr. Herbert Bousack from the Peter Grünberg Institut at the Forschungzentrum Jülich went through the same experience. Prof. Schmitz has been researching fire...

PHOTO CAPTION: The common asparagus beetle Crioceris asparagi is an important pest of asparagus crops. Photo by Keith Edkins 2003 The Common Asparagus Beetle (Crioceris asparagi) is an chief pest of Asparagus crops both in Europe and in North America; asparagus is its only food plant. The adult beetles and the larvae strip the needle-like leaves off the asparagus fronds which deprives the plants of the ability to build food reserves for future years. They also damage the shoots, thereby...

The longhorn beetles (Cerambycidae) are a family of beetles notable for their extremely long antennae. These antennae are often as long as or longer than the beetle's body in fact. The family is large, with over 20,000 species described. Several are serious pests, with the larvae boring into wood, where they can cause extensive damage to either living trees or to wood in buildings; the house longhorn Hylotrupes bajulus being a particular problem indoors. A number of species mimic ants and...
