Novel fungus helps beetles to digest hard wood
A little known fungus tucked away in the gut of Asian longhorned beetles helps the insect munch through the hardest of woods according to a team of entomologists and biochemists. Researchers say the discovery could lead to innovative methods of controlling the invasive pest, and potentially offer more efficient ways of breaking down plant biomass... view more... (2008-08-19)
New study explains why hotter is better for insects
Organisms have been able to adapt to environments ranging from cold polar oceans to hot thermal vents. However, University of Washington researchers have discovered a limit to the powerful forces of natural selection, at least when it comes to the adaptation of insects to cold temperatures. view more (2006-10-03)
Gene breakthrough heralds better prospect for malaria solution
Scientists have made a major breakthrough in understanding the genetics of the insect parasite that is being targeted by researchers as a way of preventing the spread of malaria. view more (2006-07-25)
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)
Japanese beetle may help fight hemlock-killing insect
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. view more (2007-09-11)
Quick identification needed to save Florida's citrus industry from devastating disease
The recent discovery of citrus greening (huanglongbing) in samples collected from trees in South Florida poses a definite threat to Florida's $9 billion commercial citrus industry. view more (2005-09-15)
The flourbeetle's genome sequenced for the first time
An international research consortium with the participation of a research team led by Professor Cornelis Grimmelikhuijzen from the Department of Biology, has sequenced the genome from the red flour beetle Tribolium castaneum. view more (2008-03-26)
Plants tag insect herbivores with an alarm
Rooted in place, plants can't run from herbivores—but they can fight back. Sensing attack, plants frequently generate toxins, emit volatile chemicals to attract the pest's natural enemies, or launch other defensive tactics. view more (2007-05-10)
Study: Rain forest insects eat no more tree species than temperate counterparts
A study initiated by University of Minnesota plant biologist George Weiblen has confirmed what biologists since Darwin have suspected-that the vast number of tree species in rain forests accounts for the equally vast number of plant-eating species of insects. view more (2006-08-24)
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...

Biological clocks of insects could lead to more effective pest control
Researchers at Oregon State University have discovered that the circadian rhythms or biological "clocks" in some insects can make them far more susceptible to pesticides at some times of the day instead of others. view more (2009-08-13)
Bizarre bug wears host's skin
Oxford scientists have discovered a particularly macabre method one parasite (Strepsiptera) has for disguising itself in its insect host: it wraps itself in a piece of the host's own body tissue. In this way the strepsipteran masquerades as 'self', and is protected from the insect's immune system. The mechanism whereby Strepsiptera flourish... view more... (2003-06-03)
Scientists achieve self-assembly of genetically engineered spider silk fibre in insect cells
For the first time anywhere, scientists from the Hebrew University of Jerusalem and from Germany have succeeded in producing self-assembled spider web fibres under laboratory conditions, outside of the bodies of spiders. This fibre is significantly stronger than the silk fibre made by silkworms. view more (2004-11-23)
Mosquitoes vs. Malaria: How we can win the fight
EMBL scientists have identified four mosquito proteins that affect the ability of the malaria parasite (Plasmodium) to survive and develop in the malaria-carrier mosquito (Anopheles). This breakthrough, featured in recent issues of Cell (March 5, 2004) and Science (March 26, 2004), could be used to block the transmission of malaria from mosquitoes... view more... (2004-03-22)
Insects evolved radically different strategy to smell
Darwin's tree of life represents the path and estimates the time evolution took to get to the current diversity of life. Now, new findings suggest that this tree, an icon of evolution, may need to be redrawn. view more (2008-04-14)
Bioinsecticide for combating a pest that affects the tomato and the green bean
The research project is called "Characterisation of isolated multiple Helicoverpa armigera nucleopolyhedrovirus for its development as an active material in bioinsecticides". view more (2005-09-02)
'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)
Mother knows best
Scientists have found new evidence to explain how female insects can influence the father of their offspring, even after mating with up to ten males. view more (2009-09-09)
How the 100th protein structure solved at Diamond impacts our understanding of how insects smell
New research announced today, Wednesday 30th September, by a team of leading scientists working with the UK's national Synchrotron, Diamond Light Source, could have a significant impact on the development and refinement of new eco-friendly pest control methods for worldwide agriculture. view more (2009-09-30)
Densovirus offers hope for biological control of Egypt's major cotton pest
Cotton plantations are highly important in Egypt, covering between 400 000 and 500 000 ha, 1/6 of all cultivated land. These crops are a vital source of foreign currency revenue through exports, and their state of health is therefore permanently under close surveillance. Cotton plants are indeed the target of a leaf-eating insect, the noctuid... view more... (2005-01-10)
