Viruses alter plant biochemistry in order to manipulate visiting aphids into spreading infection University of Cambridge researchers have shown that viruses use aphids as pawns, discouraging the insects from permanently settling on already-infected crops and using this forced migration to spread infection to healthy vegetation. Aphids are sap-sucking insects that attack many different types of plants and are major transmitters of crop-infecting viruses. By altering plant biochemistry,...

Corn that contains proteins that protect it from insect damage has been grown in the U.S. since the mid-1990s. Known as Bt corn, because the proteins are derived from a bacterium called Bacillus thuringiensis, these plants have been widely grown by farmers. While Bt corn has been highly effective against the European corn borer, it has been less so against the western corn rootworm, which has been documented to show resistance to the Bt proteins. In a new article in the Journal of...

Research Into Desert Locusts Discovers How Your Environment Shapes Your Thinking
2013-11-21 13:12:19

University of Leicester A team of scientists has shown how the environment shapes learning and memory by training locusts like Pavlov's dog to associate different smells with reward or punishment. Desert locusts are notorious for their devastating swarms. However, they do not always live in swarms — they switch between a lone living 'solitary phase' and a swarming 'gregarious' phase. The two phases differ profoundly in looks, behavior and in their life style. The new research from...

Insects Avoid Mating In Bad Weather

Brett Smith for redOrbit.com - Your Universe Online From a slight pain in the back to carefully observing the behavior of birds or cows, people have always been looking for signs of an impending storm. Now, a new study in the journal PLOS ONE has indicated the mating behaviors of various insects change in order avoid making themselves vulnerable during inclement weather. The study researchers hypothesized some bugs exhibit a decrease in their mating habits to lower their exposure to...

Tarantula Venom Protein May Serve As Bioinsecticide For Cotton Crop Pests
2013-09-12 10:10:21

Public Library of Science Spider venoms are usually toxic when injected into prey, but a new protein discovered in the venom of Australian tarantulas can also kill prey insects that consume the venom orally. The protein is strongly insecticidal to the cotton bollworm, an important agricultural pest, according to research published September 11 in the open access journal PLOS ONE by Glenn King and Maggie Hardy from the Institute of Molecular Bioscience at the University of Queensland,...

PHOTO CAPTION: Goliath Beetle Beetles are one of the main groups of insects. Their order, Coleoptera (meaning "sheathed wing"), has more species than any other order in the entire animal kingdom. Forty percent of all described insect species are beetles (about 350,000 species), and new species are regularly discovered. Estimates put the total number of species at between 5 and 8 million. When J. B. S. Haldane, a British geneticist, was asked what his studies of nature revealed about...

The gypsy moth, Lymantria dispar, is a moth of European origin. Life cycle Gypsy moth egg masses are laid on branches and trunks of trees, however egg masses may be found in any sheltered location. Egg masses are buff colored when first laid but may bleach out over the winter months when exposed to direct sunlight and weathering. The hatching of gypsy moth eggs coincides with budding of most hardwood trees. Larvae emerge from egg masses from early spring through mid-May. Larvae...
