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)
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)
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)
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)
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)
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)
Billions of insects join the “mile high club”
Entomologists have discovered that there are far more insects flying around above our heads than previously thought. Speaking at the Royal Entomological Society’s national meeting Entomology 2002, which will take place at Cardiff University on 12–13 September 2002, Dr Jason Chapman will say that in a typical summer month, around 3.5... view more...

'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)
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)
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)
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)
Lacewing species new to Britain unexpectedly detected in field trials of aphid sex pheromone
Scientists from IACR-Rothamsted1 and Imperial College were surprised to find large numbers of green lacewings in traps baited with a plant-derived compound aimed at improving natural biocontrol of aphid pests2. Close inspection by Stephen Brooks at the Natural History Museum identified these lacewings as Peyerimhoffina gracilis, a species new to... view more... (2001-12-17)
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 and February combined. view more (2008-08-07)
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)
Repel the aphids and you attract the leafhoppers
Things don`t always turn out as you expect when you play with genes AN ATTEMPT to make potato plants resistant to sap-sucking insects has highlighted the unpredictability of genetic engineering. The modified plants unexpectedly turned out to be vulnerable to other kinds of insect pests, demonstrating how important it is to assess each transgenic... view more... (2002-05-29)
The high cost of living with ants
A new sexually transmitted disease has been found in British ladybirds, ecologists have discovered, and it is their close association with wood ants that is to blame. Speaking at the British Ecological Society's Winter Meeting, being held at the University of York on 18-20 December 2002, Dr John Sloggett of the University of Bayreuth in Germany... view more...

John Innes Scientists Scoop Gold Medal at Chelsea Flower Show
The exhibit is a "fashion show" which explains how jumping genes, virus disease infection and bizarre chimeras cause the beautiful foliage and flowers we admire in plants. The display features a collection of beautiful common and unusual plants as "models" on the fashion catwalk. view more (1999-05-25)
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)
