Arthropod 'family tree' gets bigger through evolution studies
Would you be just as comfortable nibbling on a cricket or cockroach as you would be eating a crab?
Picking up on the smell of evolution
UA researchers have discovered some of the changes in genes, physiology and behavior that enable a species to drastically change its lifestyle in the course of evolution.
Researchers identify natural plant compounds that work against insects
Each year millions of deaths result from diseases transmitted by insects. Insects are also responsible for major economic losses, worth billions of dollars annually, by damaging crops and stored agricultural products.
Research finds orchid mantis doesn't mimic an orchid after all
In his 1879 account of wanderings in the Orient, the travel writer James Hingston describes how, in West Java, he was treated to a bizarre experience:
New forensic entomology observations expand knowledge of decomposition ecology
Fans of CSI: Crime Scene Investigation and similar TV shows know that forensic entomology involves the use of insects and other arthropods in legal matters, including homicide cases. Entomologists who are ...
Transgenic crops: Multiple toxins not a panacea for pest control
Strategies for delaying insect resistance to transgenic crops rely on assumptions that often are overly optimistic, a new study led by UA scientists shows. Published as an advance online publication by the ...
Picture this—biosecurity seen from the inside
When plants come under attack internal alarm bells ring and their defence mechanisms swing into action - and it happens in the space of just a few minutes. Now, for the first time, plant scientists - including ...
Pitcher plants 'switch off' traps to capture more ants
Insect-eating pitcher plants temporarily 'switch off' their traps in order to lure more prey into danger, new research from the University of Bristol, UK, and the University of Cambridge, UK, has found.
Study sheds light on chemicals that insects use to communicate and survive
Most insects are covered with a thin layer of hydrocarbon molecules as a waterproofing barrier. Embedded in this layer are compounds that the insects use as chemical signals for a wide variety of functions ...
Social insects, your grandma and Darwin
Darwin was not a fan of social insects, or at least not of those you're likely to step on or be stung by. Some of these critters—notably ants and termites, and certain wasps, bees and aphids—exhibit a high degree of social ...
Newly discovered assassin bug was incognito, but now it's incognita
Sometimes new insect species are discovered in the wild, and sometimes they are discovered in the drawers of old museum collections. Then there are those that are discovered by accident, which is how Dr. ...
First steps for Hector the robot stick insect
A research team at Bielefeld University has succeeded in teaching the only robot of its kind in the world how to walk. Its first steps have been recorded in a video. The robot is called Hector, and its construction ...
How trap-flowers attract and deceive pollinating food thieves
Researchers have discovered a new pollination system that involves food-thieving flies as pollinators. These flies feed on insect secretions, available when a spider, a praying mantis, or other predatory arthropods feed on ...
How blood parasites colonize and persist in small island bird populations
A new study highlights the complex factors at play for parasites that infect animal populations residing on small islands. The findings are important for understanding colonization and extinction as drivers of island biogeography.
