Beetles Keep Their Cool With Dung
2012-10-23 04:41:15

Lee Rannals for redOrbit.com - Your Universe Online The next time the thermostat hits the triple digits outside, instead of paying a high electric bill for the month, take a page out of the dung beetle's playbook and try cooling off with some fresh feces instead. Researchers have discovered that dung beetles use their dung balls to keep themselves cool as they push a weight of up to 50 times heavier than their own bodies across the hot sand. "Like an air conditioning unit, the moist...

New Beetle Species From The Society Islands
2012-10-11 06:06:30

April Flowers for redOrbit.com - Your Universe Online If exploring remote mountaintops and naming new beetle species has always been a dream of yours, you might want to jump on that now that there are two fewer such mountains left. James Liebherr, curator of the Cornell University Insect Collection, has described 14 species of predatory carabid beetles, also called ground beetles, found on Mont Tohiea and Mont Mauru in the Society Islands. Liebherr was part of a U.S. National Science...

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...

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...

Photo by Keith Edkins The beetle family Chrysomelidae, or leaf beetles is a family of over 35,000 species in more than 2,500 genera. Leaf beetles are recognizable by their tarsal formula and distinguished from long-horned beetles (family Cerambycidae) by their short, filiform antennae. Adult and larval leaf beetles feed on all...

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...

Leaf beetles are recognizable by their tarsal formula and distinguished from long-horned beetles (family Cerambycidae) by their short, filiform antennae. Adult and larval leaf beetles feed on all sorts of plant tissue. Many are economically important pests of agriculture, for example the colorado potato beetle (Leptinotarsa decemlineata), the asparagus beetle (Crioceris...
