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)
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)
The world`s most stable genome has been identified in aphid endosymbionts
Bacteria that reproduce inside aphids have not changed their genetic make-up for the last 50-70 million years. This makes the genomes of these bacteria the most stable of all organisms yet studied. This finding is presented by a team of scientists at Uppsala University, Sweden, in the latest issue of the scientific journal Science. Under the... view more... (2002-06-28)
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)
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)
'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)
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)
ISU researchers study insecticide-free method for control of soybean aphids
Two Iowa State University researchers are examining a new method of controlling soybean aphids without the use of chemical pesticides. view more (2009-09-16)
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)
Discovering soybean plants resistant to aphids and a new aphid
This year farmers in the Midwest are growing a new variety of soybeans developed by University of Illinois researchers that has resistance to soybean aphids. view more (2009-08-11)
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)
'Natural' nitrogen-fixing bacteria protect soybeans from aphids
An invasion of soybean aphids poses a problem for soybean farmers requiring application of pesticides, but a team of Penn State entomologists thinks a careful choice of nitrogen-fixing bacteria may provide protection against the sucking insects. view more (2009-04-15)
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...

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...

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)
Gene developed through conventional breeding to improve cowpea aphid resistance
The cowpea or black-eyed pea, as it is more commonly known, is a New Year's tradition for good luck. But disease and particularly aphids, which can wreck a crop within a few a days, are especially bad luck for the cowpea, according to scientists. view more (2009-07-30)
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)
Small investments to battle soybean pest paying off big, says MSU researcher
The small amount of money put toward fighting the tiny, yet destructive soybean aphid will pay big dividends in the coming years, said a Michigan State University economist, thanks to a research and outreach system developed during the last 50 years. view more (2009-03-24)
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)
