Birds, bats and insects hold secrets for aerospace engineers

ANN ARBOR, Mich.---Natural flyers like birds, bats and insects outperform man-made aircraft in aerobatics and efficiency. University of Michigan engineers are studying these animals as a step toward designing flapping-wing planes with wingspans smaller than a deck of playing cards. A Blackbird ...

Ants and avalanches: Insects on coffee plants follow widespread natural tendency

ANN ARBOR, Mich.---Ever since a forward-thinking trio of physicists identified the phenomenon known as self-organized criticality---a mechanism by which complexity arises in nature---scientists have been applying its concepts to everything from economics to avalanches. Now, researchers at the U...

Handbook of small grain insects available now

The Entomological Society of America (ESA), in cooperation with the American Phytopathological Society (APS), announces the publication of Handbook of Small Grain Insects, the latest in ESAs Insect Pest Handbooks series. This comprehensive color guide examines the biology and management of arthrop...

Tropical insects 'go the distance' to inform rainforest conservation

EAST LANSING, Mich. The long-held belief that plant-eating insects in tropical forests are picky eaters that stay close to home dining only on locale-specific vegetation is being challenged by new research findings that suggest these insects feast on a broader menu of foliage and can be consis...

Study assesses impact of fish stocking on aquatic insects

The impact fish stocking has on aquatic insects in mountain lakes can be rapidly reversed by removing non-native trout, according to a study completed by U.S. Forest Service and University of California, Davis, scientists. Their findings appear in a current online issue of the journal Freshwater...

Why do insects like to eat some plants more than others?

In a study appearing in the forthcoming issue of The American Naturalist, Tom E. X. Miller, Andrew J. Tyre, and Svata M. Louda (all of the University of Nebraska, Lincoln) examined herbivore dynamics, specifically why plants aren't all eaten at the same rate. Plant-insect ecologists typically at...

Giant insects might reign if only there was more oxygen in the air

The delicate lady bug in your garden could be frighteningly large if only there was a greater concentration of oxygen in the air, a new study concludes. The study adds support to the theory that some insects were much larger during the late Paleozoic period because they had a much richer oxygen sup...

Value of services performed by insects tops $57 billion in US

Think twice before you blithely swat, stomp, curse or ignore insects, says Cornell University entomologist John Losey, who co-authored a study that shows the dollar value of some of those insect services is more than $57 billion in the United States annually. The research appears in the journal Bio...

Gene needed for butterfly transformation also key for insects like grasshoppers

It is a marvel of nature that a creature such as a caterpillar changes into something quite different, a butterfly. Contrast that with a grasshopper, which looks largely the same from the time it hatches through its adult stage. New University of Washington research shows that a regulatory gene ...

DDT-resistant insects have additional genetic advantage that helps resistance spread

Insects that can withstand the powerful pesticide DDT that was banned in the 1970s have an additional genetic advantage over their rivals that has helped them spread across the globe ever since, according to research published in Current Biology tomorrow (9 August 2005). This discovery overturns...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

A new study investigating the respiratory system of insects may have solved a mystery that has intrigued physiologists for decades: why insects routinely stop breathing for minutes at a time. Challenging previous theories, researchers at UC Irvine and Humboldt University propose that insects suc...

Researchers find how protein allows insects to detect and respond to pheromones

University of Washington TechTransfer recently licensed software that will give scientists a huge advantage in the fight against disease. The software, known as Rosetta, predicts how proteins fold, information that is highly valuable to biological and biomedical researchers. UW Tech Transfer's Digi...

Carbon nanoparticles toxic to adult fruit flies but benign to young

New insights into health and environmental effects of carbon nanoparticles
