Grazing animals help spread plant disease
Researchers have discovered that grazing animals such as deer and rabbits are actually helping to spread plant disease - quadrupling its prevalence in some cases - and encouraging an invasion of annual grasses that threaten more than 20 million acres of native grasslands in California. view more (2008-12-30)
Aphids are sentinels of climate change
Aphids are emerging as sentinels of climate change, researchers at BBSRC-supported Rothamsted Research have shown. One of the UK's most damaging aphids - the peach-potato aphid (Myzus persicae) - has been found to be flying two weeks earlier for every 1 degree C rise in mean temperature for January... view more (2008-08-07)
Insects take a bigger bite out of plants in a higher CO2 world
Atmospheric carbon dioxide levels are rising at an alarming rate, and new research indicates that soybean plant defenses go down as CO2 goes up. Elevated CO2 impairs a key component of the plant's defenses against leaf-eating insects, according to the report. view more (2008-03-25)
Gene's 'selective signature' aids detection of natural selection in microbial evolution
Scientists at MIT have come up with a mathematical approach for analyzing a protein simultaneously in a set of ecologically distinct species to identify occurrences of natural selection in an organism's evolution. view more (2008-03-19)
'Jekyll and Hyde' bacteria offer pest control hope
New research at York has revealed so-called 'Jekyll and Hyde' bacteria, suggesting a novel way to control insect pests without using insecticides. view more (2007-12-20)
Plant viruses from past provide ecological clues
Taking the medical history of a grassland may seem a bit esoteric - after all, how sick can grass be? However, scientists have discovered plant viruses from as early as 1917 containing information crucial not only for plant scientists, but for those in ecology, human health and bioterrorism. view more (2007-10-09)
Amber specimen captures ancient chemical battle
It appears that chemical warfare has been around a lot longer than poison arrows, mustard gas or nerve weapons - about 100 million years, give or take a little. view more (2007-08-30)
Transgenic maize is more susceptible to aphids
The environmental consequences of transgenic crops are the focus of numerous investigations, such as the one published in the journal PloS ONE. view more (2007-08-30)
Chickadee, nutchatch presence in conifers increases tree growth, says CU-Boulder study
Chickadees, nuthatches and warblers foraging their way through forests have been shown to spur the growth of pine trees in the West by as much as one-third, according to a new University of Colorado at Boulder study. view more (2007-08-02)
In a bug-eat-bug world, researchers are using a unique Chinese import to battle soybean aphids
University of Minnesota scientists are field testing a beneficial insect, a stingless wasp from China also known as Binodoxys communis, that kills soybean aphids. A successful field test would be a major breakthrough in controlling a damaging crop pest. view more (2007-07-25)
Aphids make 'chemical weapons' to fight off killer ladybirds
Cabbage aphids have developed an internal chemical defence system which enables them to disable attacking predators by setting off a mustard oil 'bomb'. view more (2007-07-11)
Thale cress goes on the defensive
Thale cress has a complicated defence technique against insects and microorganisms that use the plant as a source of food. view more (2007-05-15)
Why some aphids can't stand the heat
For pea aphids, the ability to go forth and multiply can depend on a single gene, according to new research. view more (2007-04-20)
Evolution of symbiosis
The aphid Acyrthosiphon pisum depends on a bacterial symbiont, Buchnera aphidicola, for amino acids it can't get from plants. The aphid, in turn, provides the bacterium with energy and carbon as well as shelter inside specialized cells. view more (2007-04-10)
Mayo researcher discovers target site for developing mosquito pesticides
A Mayo Clinic researcher has discovered a target site within malaria-carrying mosquitoes that could be used to develop pesticides that are toxic to the Anopheles gambiae mosquito and other mosquito species. view more (2006-12-21)

Perennial wheat research looks at options for producers
Perennial wheat? The possibility is being looked at by a Texas Agricultural Experiment Station researcher. view more (2006-11-29)
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. view more (2006-10-27)
Biodiversity controls ecological 'services,' report scientists in comprehenisive analysis
Accelerating rates of species extinction pose problems for humanity, according to a comprehensive study headed by a biologist at the University of California, Santa Barbara and published in the journal Nature this week. view more (2006-10-26)
Mayo Clinic study could lead to safer pesticides
Each year millions of dollars in crops are lost to two insects notorious for devastating farms: the greenbug (Schizaphis graminum) and the English grain aphid (Sitobion avenae). view more (2006-10-13)
Evolutionary harmony for stinkbugs and their gut bacteria: A perfect match
With some 1 million species and counting, insects may be the most abundant class of animals living today. Their protective exoskeleton, prolific reproductive rate, and wings help their cause, as do the symbiotic bacteria that inhabit their cells, gut, or body cavity. view more (2006-10-10)
Water found to be main culprit in Argentine ant invasions
According to a study conducted by two biologists at the University of California, San Diego, Argentine ants in Southern California need wet soil to live and breed. view more (2006-03-30)
Defeating the 'superpests'
Scientists have developed a new technique that makes pesticides more effective by removing insects' ability to exhibit resistance. view more (2005-10-10)
Alarm pheromone causes aphids to sprout wings
Chemical communication within insect species is often much more sophisticated than expected. When aphids are attacked by predators such as ladybird beetles, they release an alarm pheromone, (E)-ß-farnesene, that has long been known to cause other aphids to walk around or drop from the plant. view more (2005-05-18)
