Rising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the University of Michigan suggests. The research focused on the effects of elevated carbon dioxide on common milkweed, Asclepias syriaca. Milkweed is one of many plants that produce toxic or bitter chemical compounds to protect themselves from being eaten by insects. These chemical defenses are the result of a...

Scientists discover an 'atmospheric imprint' in insects, revealing where they are most likely to survive should climate change alter their ecosystem 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. Applying a method previously only used to examine the possible effects of...

Researchers have discovered the 100 million-year-old ancestor of a group of large, carnivorous, cricket-like insects that still live today in southern Asia, northern Indochina and Africa. The new find, in a limestone fossil bed in northeastern Brazil, corrects the mistaken classification of another fossil of this type and reveals that the genus has undergone very little evolutionary change since the Early Cretaceous Period, a time of dinosaurs just before the breakup of the supercontinent...

Scientists studied the defences used by caterpillars that transform into large white butterflies, called Pieris brassicae. The insects regurgitate semi-digested cabbage leaves to make them smell and taste unpleasant to predators. The team found, however, that frequent use of this defence reduces the caterpillars' growth rate and the number of eggs they produce. It remains unclear why their defences affect them in this way, but the loss of nutrition from frequent regurgitation is thought to...

An Anglo-Swiss research project has found that the impact of disease-resistant genetically-modified wheat plants on insects may be negligible. Many studies have looked at the effects of genetically-modified (GM) plants on single non-target insects. However, agro-ecosystems are characterised by numerous insect species forming food webs. This study is the first to investigate different transgenic disease-resistant wheat lines and their effect on the structure of whole aphid-parasitoid food...

The humble ginger root could be the key to conserving the UK's largest and most spectacular terrestrial beetle "“ the stag beetle. Ecologists from Royal Holloway, University of London and the University of York have developed a series of new methods to monitor stag beetle numbers "“ including ginger lures to trap adult beetles and tiny microphones to detect sounds made by the larvae in their underground nests. Conservation efforts have been hampered until now because ecologists...

One of the world's rarest and most unique looking flies, the "terrible harry fly," has been rediscovered in Kenya for the first time since 1948, researchers announced on Wednesday. According to the AFP, Dr. Robert Copeland and Dr. Ashley Kirk-Spriggs of the International Center of Insect Physiology and Ecology (ICIPE) "found the fly, known as Mormotomyia Hirsuta, in its only known habitat, a cave-like rock cleft in Ukazi Hill east of Nairobi." It marked just the third time the species had...

Flying insects' altitude control mechanisms are the focus of research being conducted in a Caltech laboratory under an Air Force Office of Scientific Research grant that may lead to technology that controls altitude in a variety of aircraft for the Air Force. "This work investigates sensory-motor feedback mechanisms in the insect brain that could inspire new approaches to flight stabilization and navigation in future insect-sized vehicles for the military," said Dr. Willard Larkin, AFOSR...

Head lice shrivel in study as device hits the market Four years after the LouseBuster prototype made headlines when research showed the chemical-free, warm-air device wiped out head lice on children, a new study reveals that a revamped, government-cleared model is highly effective. "For a louse, it's like sticking your head out a window at 100 miles an hour; they're going to get dried out," says University of Utah biology Professor Dale Clayton, senior author of the study and a founder of...

In Australia, when crossing from one state to another, travelers may encounter a quarantine stop and may be required to forfeit recently purchased fruits and vegetables as a hedge against invasive pests. But in the U.S., crossing state lines is free wheeling, according to researchers from the U.S., Australia and New Zealand, who evaluated the threat of invasive pests to states from within the country. "We concluded that the immediate threat from known invasive insect pests is greater from...
