Leicester research paves way for first use in Europe of an insect to fight invasive plant

Researchers at the University of Leicester have paved the way for the first ever use in Europe of an insect (biocontrol) to combat an invasive plant species in Britain. University of Leicester biologists established that the Japanese Knotweed in Britain was one the biggest females in the world-...

Team approach appears to work best for insect colonies

The study's findings appear to echo the insect worlds portrayed in the animated films Antz and Bee Movie, in which the characters live in rigidly conformist societies. Scientists from the Universities of Edinburgh and Oxford reached their conclusion by creating a mathematical model to study the...

Ecological insect pest management for Guam

University of Guam scientist Dr. G. V. P. Reddy has been awarded a $60,000 grant from the Sustainable Agriculture Research and Education (SARE) program of the US Department of Agriculture.

A natural, alternative insect repellent to DEET

Lanham, MD; February 5, 2009 Isolongifolenone, a natural compound found in the Tauroniro tree ( Humiria balsamifera ) of South America, has been found to effectively deter biting of mosquitoes and to repel ticks, both of which are known spreaders of diseases such as malaria, West Nile virus, and ...

Florida professor creates endowment for insect scientists

Dr. Nan-Yao Su, a professor of entomology at the University of Florida, has donated $250,000 to the Entomological Society of America (ESA) for the establishment of an endowment to award creative entomologists who have demonstrated the ability to find alternative solutions to problems that signific...

Honey bees on cocaine dance more, changing ideas about the insect brain

CHAMPAIGN, Ill. In a study that challenges current ideas about the insect brain, researchers have found that honey bees on cocaine tend to exaggerate. Normally, foraging honey bees alert their comrades to potential food sources only when they've found high quality nectar or pollen, and only wh...

Economic value of insect pollination worldwide estimated at 153 billion euros

This press release is available in German . Avignon/Halle(Saale). INRA and CNRS French scientists and a UFZ German scientist found that the worldwide economic value of the pollination service provided by insect pollinators, bees mainly, was 153 billion in 2005 for the main crops that f...

Biocontrol insect exacerbates invasive weed

Biocontrol agents, such as insects, are often released outside of their native ranges to control invasive plants. But scientists in Montana have found that through complex community interactions among deer mice, native plants and seeds, the presence of an introduced fly may exacerbate the effects ...

Tiny pest-eating insect fights fruit flies

HARROW, ONTARIO -- Farmers and vineyard owners have a new weapon in their pest management arsenal. A commonly used parasitoid, or parasitic insect that kills its host, has proven to be quite effective in the control of fruit flies in vineyards. These tiny pest-devouring insects are considered to b...

Researchers uncover world's oldest fossil impression of a flying insect

MEDFORD/SOMERVILLE, Mass. - While paleontologists may scour remote, exotic places in search of prehistoric specimens, Tufts researchers have found what they believe to be the world's oldest whole-body fossil impression of a flying insect in a wooded field behind a strip mall in North Attleboro, Ma...

Japanese beetle may help fight hemlock-killing insect

Blacksburg, Va. The eastern hemlock, a tall, long-lived coniferous tree that shelters river and streamside ecosystems throughout the eastern United States and Canada, is in serious danger of extinction because a tiny, non-native insect is literally sucking the life out of it. Entomologists at ...

The insect vector always bites twice

The reality of the threat from vector-borne diseases has been recognized and the problem is prompting research scientists to take a strong interest. Most of these infections, classified as emerging or re-emerging diseases, are linked to ecosystem changes, climatic variations or pressure from human...

Bypassing eggs, flu vaccine grown in insect cells shows promise

Wheat can fatally starve insect predators

A newly identified wheat gene produces proteins that appear to attack the stomach lining of a crop-destroying fly larvae so that the bugs starve to death. The gene's role in creating resistance to Hessian flies was a surprise to U.S. Department of Agriculture and Purdue University researchers, d...

New genetic analysis forces re-draw of insect family tree

The family tree covering almost half the animal species on the planet has been re-drawn following a genetic analysis which has revealed new relationships between four major groups of insects. Scientists have found that flies and moths are most closely related to beetles and more distantly relat...

Similar Stem Cells In Insect And Human Gut

Looking through his handmade microscope in 1702, it was Anton van Leeuwenhoek who first described the workings of a nano machine. He observed the rapid contraction of a stalk tethering the cell body of a tiny protozoan, Vorticella convallaria, to the surface of a leaf. Little did van Leeuwenhoek im...

Stolen gene allows insect virus to enter cells

A gene enabling an insect virus to enter new cells was likely stolen from a host cell and adapted for the virus's use, researchers at Boyce Thompson Institute (BTI) at Cornell University report. Virologists have long thought of baculoviruses, a group of viruses that can liquefy their insect hosts...

Stealth Worms May Improve Insect Pest Control

Nematodes comprise a worm family so large it literally covers the earth. They range in size from less than a micron in length to as much as 26 feet. Worldwide interest has begun to focus on microscopic nematodes that live with symbiotic bacteria. "We study these nematodes -- which are actually inse...

Influenza vaccine uses insect cells to speed development

Using a strategy involving a genetically modified baculovirus and caterpillar cells scientists from Protein Sciences Corporation have been able to speed up a key step in the development of an experimental cell-based influenza vaccine.
