Dung Beetles Use Milky Way For Nocturnal Navigation
2013-01-24 14:35:18

Lee Rannals for redOrbit.com — Your Universe Online Back before technology emerged into everyone's pockets, sailors used the stars as their GPS system when navigating the seven seas. While that way of navigation is a little outdated for humans, it´s still a modern technology for dung beetles. Scientists wrote in the journal Current Biology about how dung beetles guide their way through even the darkest of nights by the soft glow of the Milky Way in the sky. Researchers say...

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...

Diet Of The Lady Beetle Influences Its Effectiveness As Biocontrol Agent
2013-01-11 15:47:47

U.S. Department of Agriculture (USDA) By examining what lady beetles eat, U.S. Department of Agriculture (USDA) scientists are learning more about the movement of these beneficial insects in farm fields–and whether they'll actively feed on crop pests. Agricultural Research Service (ARS) entomologist Jonathan Lundgren at the agency's North Central Agricultural Research Laboratory in Brookings, S.D., and former ARS entomologist Michael Seagraves were part of a team of ARS and...

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...

After metamorphosis European forest cockchafers benefit from the same bacterial symbionts housed during their larval stage. Apart from the common European cockchafer (Melolontha melolontha), the European forest cockchafer (Melolontha hippocastani) is the most common species of the Melolontha genus. These insects can damage huge areas of broadleaf trees and conifers in woodlands and on heaths. Cockchafers house microbes in their guts that help them to digest their woody food, such as...

Insect Diversity Studied In The Rainforests Of Panama
2012-12-14 05:46:43

April Flowers for redOrbit.com - Your Universe Online Until now, scientists have had a problem estimating the exact numbers of arthropods — a group that includes insects, arachnids, and crustaceans - on Earth, even though we know they comprise a majority of the multicellular species on the planet. Because of their small size, frequent movements, and inaccessible habitats, quantifying their abundance has been difficult despite the fact that they are the most numerous phylum on the...

Renaissance Artwork Shows History Of Wormholes
2012-11-21 10:36:50

Brett Smith for redOrbit.com - Your Universe Online European Renaissance printers probably knew they were recording history for future generations, but what they didn´t realize is that they were also recording events related to biological history. Blair Hedges, a professor of biology at Penn State University, has discovered ℠wormholes´ that pock-marked European printed art from that time period were formed by two different types of beetles, which had separate, clearly...

Soldier Beetle Defense Turned Into Biotech Opportunity Through Gene Discovery
2012-11-08 10:31:11

CSIRO Australia New antibiotic and anti-cancer chemicals may one day be synthesized using biotechnology, following CSIRO's discovery of the three genes that combine to provide soldier beetles with their potent predator defense system. CSIRO researchers, and a colleague at Sweden's Karolinska Institute, published details of the gene identification breakthrough and potential applications recently in the international journal Nature Communications. "For the first time, our team has been...

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...

Competition Of Males Over Females
2012-10-25 12:18:31

An evolutionary engine of genital evolution When a female mates with several males, these will compete over the fertilization her eggs. This is an important evolutionary force that has led to the evolution of a diversity of male sexual organ morphologies. This is revealed in a study of seed beetles published today in the leading scientific journal Current Biology. In higher plants, the influential classification system developed by Carl von Linnaeus relied on the fact that the...

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...
