Study finds nearly 50% of retail firewood infested with insects
A new study published in the Journal of Economic Entomology reports that live insects were found in 47% of firewood bundles purchased from big box stores, gas stations and grocery stores in Colorado, New Mexico, Utah and Wyoming. View More (2012-10-09)
Bright autumn colouration in trees - a warning signal to insects?
Most deciduous trees change colour in autumn. However, both within and between species, there is considerable variation both in the timing and magnitude of autumn colour change. Hamilton and Brown recently proposed a hypothesis to explain this phenomenon. Their idea was that the bright autumn colouration in trees is a warning signal to insects about investment in chemical defence. In the... View More (2003-09-17)
Spread of plant diseases by insects can be described by equations that model interplanetary gravity
Researchers from Penn State University and the University of Virginia show that the spread of diseases by insects can be described by equations similar to those that describe the force of gravity between planetary objects. View More (2006-09-05)
Insects see crops clearly when the weeds have gone
All gardeners know that their plants have to compete against insects and weeds. We apply insecticides to protect plants from the munching hordes, and we apply herbicides, or hoe, to protect plants from weeds. But, according to Stan Finch and Rosemary Collier of Horticulture Research International, Wellesbourne, the latter is a bad move that actually helps insects to find our crop plants. Writing...

Proteins in unroasted coffee beans may become next-generation insecticides
Scientists in Brazil are reporting for the first time that coffee beans contain proteins that can kill insects and might be developed into new insecticides for protecting food crops against destructive pests. View More (2010-04-01)

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)
Forest pests accumulating despite regulations
Nonindigenous insects and pathogens continue to become established in US forests with regularity despite regulations intended to prevent this. View More (2010-12-06)
Migratory moths profit from their journey
It isn't only birds that move south as autumn approaches. Some insects also live their lives on the same principle. View More (2012-09-13)
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)
Chasing high flying insects with radar
New developments to vertical looking radar (VLR) mean that scientists at Rothamsted, Harpenden are now tracking insects to find out where they go and how they behave when they take to the skies. "The sheer abundance of insects is amazing," says Dr Alan Smith of Rothamsted Radar Entomology Unit. "The actual biomass of insects above us on a summer`s day is enormous and the height at which they fly... View More (2002-06-26)
Could Bt transgenic crops have nutritionally favourable effects on insects?
Researchers from Imperial College, England have just shown in a forthcoming article in the journal Ecology Letters, that insect larvae can use an engineered toxin (Cry1Ac) as a supplementary food source. They found that toxin-resistant larvae of the Diamondback Moth developed faster and had a greater pupal weight in the presence of the toxin. This could be a genetic effect, linked indirectly to...

Voicemail discovered in nature
Insects can use plants as 'green phones' for communication with other bugs. A new study now shows that through those same plants insects are also able to leave 'voicemail' messages in the soil. View More (2012-06-13)
'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)
Using insects to test for drug safety
Insects, such as some moths and fruit flies, react to microbial infection in the same way as mammals and so can be used to test the efficiency of new drugs, thereby reducing the need for animal testing. View More (2009-09-08)
Folding wings - just the business for insect survival
Just like modern businesses, insects have had to diversify to survive, according to University of York scientist Peter Mayhew. The ability to fold their wings is one device they have adopted over the years as part of the struggle for survival, says Dr Mayhew. And folding wings have given the insects which adopted them - including bugs, beetles, flies, moths and wasps -a distinct advantage over... View More (2002-05-01)
Insects hold atomic clues about the type of habitats in which they live
Scientists have discovered that insects contain atomic clues as to the habitats in which they are most able to survive. The research has important implications for predicting the effects of climate change on the insects, which make up three-quarters of the animal kingdom. View More (2011-02-17)
K-State researchers study gene regulation in insects
Susan Brown, an associate professor of biology at Kansas State University, is interested in how evolution generates so much diversity in insects shapes and forms. View More (2006-04-28)
Mosquito parasite may help fight dengue fever
Dengue fever is a terrible viral disease blighting many of the world's tropical regions. Carried by mosquitoes, such as Aedes aegypti, 40% of the world's population is believed to be at risk from the infection. View More (2009-05-01)
Scientists discover how to send insects off the scent of crops
Biotechnology and Biological Sciences Research Council (BBSRC)-funded research, published this week in Chemical Communication, describes how scientists have discovered molecules that could confuse insects' ability to detect plants by interfering with their sense of smell. This could reduce damage to crops by insect pests and contribute to food security. View More (2009-09-24)
