Insect Shield blankets offer invisible, odorless protection from a variety of insects that can carry Lyme disease, West Nile virus, malaria and other insect-borne diseases. Greensboro, NC & Seattle, WA (PRWEB) April 15, 2014 Spring is here which means the bugs are on their way... It is time to get ready for the annual battle against Spring/Summer insects. According to the CDC, Lyme disease has become an epidemic - and not just in the Northeast. More than 300,000 cases of Lyme are...

Attracting Or Repelling Insects Using Different Scents
2014-04-01 15:48:26

University of Zurich Flowering plants attract pollinating insects with scent from their flowers and bright colors. If they have become infested with herbivores like caterpillars, they attract beneficial insects like parasitic wasps with the help of scent signals from their leaves. The wasps then lay their eggs in the caterpillars and kill the parasites. Floral and foliar scents can, however, mutually reduce their attractiveness. That's why flowering plants face a dilemma: should they use...

3D Movie From Inside Live Flying Insects
2014-03-31 09:11:47

[ Watch The Video: Three-Dimensional Visualization of the Insect Thorax ] University of Oxford The flight muscles moving inside flies have been filmed for the first time using a new 3D X-ray scanning technique. 3D movies of the muscles were created by a team from Oxford University, Imperial College London, and the Paul Scherrer Institute (PSI), using the PSI's Swiss Light Source, a powerful X-ray source. The movies offer a glimpse into the inner workings of one of nature's most...

Earliest Stick Insect Fossils Discovered
2014-03-20 08:06:36

PLOS Wing shape and coloration pattern suggest plant-mimicking stick insects from the Early Cretaceous An ancient stick insect species may have mimicked plant leaves for defense, according to a paper published in the open-access journal PLOS ONE on March 19, 2014 by Maomin Wang, from Capital Normal University, China and colleagues. Many insects have developed defense mechanisms, including the ability to mimic the surrounding environment. Stick and leaf insects mimic plants from...

Specialization By Insect Species Is The Key
2014-03-14 14:54:57

University of Iowa Most of us already imagine the tropics as a place of diversity—a lush region of the globe teeming with a wide variety of exotic plants and animals. But for researchers Andrew Forbes and Marty Condon, there's even more diversity than meets the eye. In a paper published in the March 14 issue of the journal Science, Forbes and Condon report the discovery of extraordinary diversity and specialization in the tropics. The paper builds upon previous research conducted...

Researchers Use Plant-produced Sex Pheromone To Trap Moths
2014-02-27 14:24:45

Kansas State University A collaborative experiment involving a Kansas State University biochemist may mark the beginning of an effective, environmentally friendly plant-based method of insect control. Timothy Durrett, assistant professor of biochemistry and molecular biophysics, was part of the collaboration that used various plant and moth enzymes to engineer plants that emitted sex pheromones that mimic those naturally produced by two species of moths. The research recently...

Road Map And Dictionary For The Arthropod Brain

Daniel Stolte, University of Arizona By providing a standardized nomenclature for the architecture of insect brains, UA neuroscientists will help improve studies of human brain function and disease When you're talking about something as complex as the brain, the task isn't any easier if the vocabulary being used is just as complex. An international collaboration of neuroscientists has not only tripled the number of identified brain structures, but created a simple lexicon to talk about...

How Stick Insects Harness Friction To Grip Without Sticking
2014-02-19 11:18:56

University of Cambridge When they’re not hanging upside down, stick insects don’t need to stick. In fact, when moving upright, sticking would be a hindrance: so much extra effort is required to ‘unstick’ again with every step. Latest research from Cambridge’s Department of Zoology shows that stick insects have specialized pads on their legs designed to produce large amounts of friction with very little pressure. When upright, stick insects aren’t sticking at all, but...

Using Asian Longhorned Beetles Pheromone To Manage Pest
2014-02-13 14:21:18

Penn State Female Asian longhorned beetles lure males to their locations by laying down sex-specific pheromone trails on tree surfaces, according to an international team of researchers. The finding could lead to the development of a tool to manage this invasive pest that affects about 25 tree species in the United States. "Tens of thousands of hardwood trees, mostly maples, have been cut down and destroyed in New York, Ohio and Massachusetts because of the Asian longhorned beetle,"...

Extracting Plant DNA From Grasshopper Guts Improves Understanding Of Plant-insect Interactions
2014-02-06 14:12:58

[ Watch the Video: Demonstration of Grasshopper Dissection ] American Journal of Botany Grasshoppers may be small, but the damages they are causing to the US agriculture industry are anything but. Every year, they feed on crops and on rangelands needed for raising livestock, costing landowners millions of dollars. Although they pose a major threat, grasshopper populations play a positive role in cycling nutrients from decomposing plant matter back into the soil. A new method to...
