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...

Beetle-Fungus Disease Threatens Crops And Landscape Trees In Southern California

'Fusarium dieback' severely damaged avocados in Israel, says UC Riverside plant pathologist Akif Eskalen, who identified the fungus A plant pathologist at the University of California, Riverside has identified a fungus that has been linked to the branch dieback and general decline of several backyard avocado and landscape trees in residential neighborhoods of Los Angeles County. The fungus is a new species of Fusarium . Scientists are working on characterizing its specific...

Climate change puts spruce forests at greater risk of bark beetle attacks Climate change appears to be good news for destructive bark beetles, according to a new study by Lorenzo Marini from the University of Padova in Italy, and his team. Their work, published online in Springer's Climatic Change, shows that there were more attacks by the spruce bark beetle on European Alpine spruce forests over a 16 year period, as temperatures rose and rainfall dropped. Shifts in temperature,...

Periodic outbreaks of bark beetles can cause annual losses of millions of dollars and pose serious challenges for forest managers, and the suppression of outbreaks is particularly difficult and expensive. According to T. D. Schowalter, author of a new open-access article in the Journal of Integrated Pest Management called "Ecology and Management of Bark Beetles (Coleoptera: Curculionidae: Scolytinae) in Southern Pine Forests," preventative measures are most effective in minimizing losses...

Plants Mimic Scent Of Pollinating Beetles
2012-04-04 03:33:16

The color and scent of flowers and their perception by pollinator insects are believed to have evolved in the course of mutual adaptation. However, an evolutionary biologist from the University of Zurich has now proved that this is not the case with the arum family at least, which evolved its scent analogously to the pre-existing scents of scarab beetles and thus adapted to the beetles unilaterally. The mutual adaptation between plants and pollinators therefore does not always take place....

The Scarlet Lily Beetle (Lilioceris lilii) is native to Europe but is now widely found in North America. Larvae damage cultivated lily and Fritillaria plants. 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...

Ladybirds, also known as ladybugs or lady beetles are a family, Coccinellidae ("little sphere"), of beetles. The name is thought to allude to the Blessed Virgin Mary in the Catholic faith. Ladybirds are found worldwide, with over 4,500 species described - more than 450 native to North America alone. Ladybirds are small insects, ranging from 1 mm to 10 mm (0.04 to 0.4 inches), and are usually yellow, orange, or red with small black spots on their carapace, and black legs, head and feelers. As...

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...
