New tool for comparative gene studies
A great deal is known about how model organisms such as fruit flies, nematodes and mice develop. But what about beetles, frogs, and birds? Scientists who study gene function in non- model organisms may get a boost from a new technique developed by Nipam Patel, Ph.D., assistant professor of organismal biology & anatomy and Howard Hughes Investigator at the University of Chicago.

UF research ties homosexual behavior in beetle to evolution
In a new hypothesis for a behavior observed in a number of species, two researchers say the process of natural selection may explain homosexual behavior in a beetle that preys on citrus in South Florida. (1999-10-19)

Urban Restorer Sees Trash Trees, Beetles As Signs Of Hope
Ailanthus, the trash tree famous for growing in sidewalk cracks, sewer grates and vacant lots, is usually unwelcome in a landscape architect's plans but Penn State's Ken Tamminga says its presence in Pittsburgh's Nine Mile Run area is a sign of hope. (1999-05-13)

A Mother's Love? New UD Theory Explains Why Good Insect Moms Risk Death To Save Their Only Children
Good insect moms ferociously protect their young by fanning their wings and charging predators--but only when they must pin all their hopes on a single batch of eggs, a University of Delaware scientist reports in the new issue of the journal, Animal Behaviour. Bug moms who lay multiple batches are far more likely to (1999-03-29)

Tip Sheet: Citrus Limonoids Versus Cancer, Cholesterol And Insects
Limonoids are compounds in citrus fruits, generally found in the peels, that produce the familiar bitter taste. More importantly, limonoids have been shown to produce anticancer activities in animals and inhibit the spread of human breast cancer cells in culture. More than a dozen research papers related to these compounds are being presented during the national meeting of the American Chemical Society, the world's largest scientific society, in Anaheim, Calif., March 21 - 25.

Common Cannibals, A New Study Examines The Role That Intraspecific Predation Plays In Determining The Dynamics Of A Population
While humans may find the thought of cannibalism unsettling, other species seem to eat their own kind quite readily. Once viewed as a laboratory artifact, a recent study published in the December issue of Ecology, has shown a definitive link between cannibalism and population stabilization among flour beetles. (1998-12-10)

Jurassic Beetle: CSIRO Entomologist Discovers Living Fossil
CSIRO entomologist Dr. John Lawrence admits it was a thrill: the delicate bronze-and-white spiny beetle glittering in the light of his microscope was a living fossil, whose ancestral roots go back almost 200 million years. (1998-09-28)

Butterfly Wings, Beetle Horns Teach Biologists Basic Lesson In Development's Laws
Catepillars treated to stunt the growth of their future hind wings develop into butterflies with abnormally large front wings, two Duke biologists have discovered. And scarab dung beetles treated to stunt the growth of their horns sprout larger eyes. (1998-03-30)

Insect Taste Buds Target Of Control Method
Insects are probably more finicky than cats when it comes to their diets, so a Penn State insect toxicologist is targeting their taste buds in an effort to protect crops. (1998-03-30)

Plants Thrive With Insect-Induced Immune Responses
Researchers at the University of California, Davis, have demonstrated for the first time that plants realize a net benefit when their internal defense systems are (1998-02-13)

Corn Rootworm Changing Behavior, Posing New Threat To Crops
Crop rotation is failing as a defense against Western corn rootworms in a growing number of Midwest fields. The beetles have adapted, are spreading and pose a threat to corn crops this year, say scientists at the University of Illinois. (1998-02-06)

Tiger Beetles Go Blind At High Speeds
Entomologists have long noticed that tiger beetles stop-and- go in their pursuit of prey. But up to now, scientists have had no idea why this species of beetle attacks its food in fits and starts. Why do they stop and go? During hot pursuit of prey, the tiger beetles go blind. (1998-01-16)

SFU Researcher Fools Forest Pest Into 'Barking Up The Wrong Tree'
Simon Fraser University researcher Dezene Huber is investigating the secret scent life of two of British Columbia's most destructive forest insect pests. His goal? To fool the insects -- two species of bark beetles -- into bypassing vulnerable trees, using non-host scents to disguise trees they would normally attack. (1997-11-28)

Female Fireflies Lure Males For Defense Chemical
The characteristic light flashes that summon male fireflies of the genus Photinus could come from female Photinus fireflies. Just as likely, the signaling females are from a different genus. The femmes fatales fireflies are luring unrelated males close enough to eat them. The males contain defensive chemicals that females need to repel predators, such as spiders. (1997-08-26)

Bog Beetle, Misidentified For 85 Years, Is 'Discovered' At Cornell
A beetle sitting in a collection at Cornell Univ. has been identified by Cornell entomologist (1997-01-14)

Two Recent Fossil Discoveries Show Insects' Recycling Traits
Recent discoveries of beetle-ravaged dinosaur bones and the oldest fossil evidence of ants on Earth have opened a new window on the powerful recycling role played by insects in Jurassic ecosystems, according to a University of Colorado at Boulder researcher (1996-10-27)

Asian Beetle, New In This Country, Threatens Brooklyn's Shade Trees
Cornell University scientists have confirmed what they believe is the first known infestation of an Asian longhorned beetle, Anoplophora glabripennis, a large beetle that is attacking Brooklyn's horsechestnut and Norway maple tree population. The Norway maple is the most planted shade tree throughout New York state. (1996-09-12)

New Study Confirms Bering Land Bridge Flooded Later Than Previously Believed
A new study confirms the Bering Land Bridge that carried ancient wanderers from Asia into North America was not inundated by rising seas until about 11,000 years ago, according to a University of Colorado at Boulder researcher (1996-07-03)

Southern Pine Beetle Reaching Outbreak Levels In North Florida
Southern Pine Beetle populations have exploded to outbreak levels along the Suwannee River in Hamilton and Madison counties, where the tree-killing beetle has invaded several pine plantations. Entomologist John L. Foltz of the University of Florida'sInstitute of Food and Agricultural Sciences said forest owners throughout North Florida need to check their stands and begin control measures if they spot the voracious beetle. (1996-07-03)

Enticed By A Chemical Tease, Female Beetles Are Rewarded With A Nuptial Gift To Protect The Next Generation
Spanish fly aphrodisiac really works for guys -- bugs that is, Cornell researchers report in Proceedings of the NAS (1996-06-25)
