- Fire Ant-attacking Fly Spreading Rapidly In Texas
09-29-2006 · ScienceDaily
Parasitic flies introduced to control red imported fire ants have spread over four million acres in central and southeast Texas since the flies' introduction in 1999, researchers at the University of Texas at Austin have discovered using new flytraps they developed.

- Fighting like a girl or boy determined by gene in fruit flies
11-19-2006 · EurekAlert!
Fighting like a girl or fighting like a boy is hardwired into fruit fly neurons, according to a study in the November 19 Nature Neuroscience advance online publication by a research team from Harvard Medical School and the Institute of Molecular Pathology in Vienna. The results confirm that a gene known as "fruitless" is a key factor underlying sexual differences in behavior.

- Researchers find link between food odors and lifespan in fruit flies
02-01-2007 · EurekAlert!
Researchers studying the fruit fly, Drosophila melanogaster, find that exposure to nutrient-derived odors can module lifespan and partially reverse the longevity-extending effects of dietary restriction.

- Flies' evasive move traced to sensory neurons
11-29-2007 · EurekAlert!
When fruit fly larvae are poked or prodded, they fold themselves up and corkscrew their bodies around, a behavior that appears to be the young insects' equivalent of a "judo move," say researchers reporting online on Nov. 29 in the journal Current Biology, a publication of Cell Press. They now trace that rolling behavior to neurons resembling those that sense pain.

- Similar brain chemicals influence aggression in fruit flies and humans
04-22-2007 · EurekAlert!
Serotonin is a major signaling chemical in the brain, and it has long been thought to be involved in aggressive behavior in animals and humans. Another brain chemical signal, neuropeptide Y (aka neuropeptide F in invertebrates), is also known to affect an array of behaviors in many species, including territoriality in mice. A new study at The Neurosciences Institute (San Diego) shows that these two chemicals also regulate aggression in the fruit fly, Drosophila melanogaster.

- With fruit fly sex, researchers find mind-body connection
11-30-2006 · EurekAlert!
The fruit fly gene "doublesex" is responsible for ensuring that male flies look male and females look female. New Brown University research led by biologist Michael McKeown shows that doublesex not only helps shape bodies but also shapes behavior, acting with together with the gene "fruitless" to guide flies' courtship routines and responses. The finding, published in Nature Genetics, shows that sexual development in flies -- and, perhaps, in humans -- is a more complicated proposition than previously thought.

- Tiny pest-eating insect fights fruit flies
12-06-2007 · EurekAlert!
Farmers and vineyard owners have a new weapon in their pest management arsenal. A commonly used parasitoid, or parasitic insect that kills its host, has proven to be quite effective in the control of fruit flies in vineyards.

- Resistance and genetic sensitivity to sleeping sickness
10-13-2006 · EurekAlert!
Human African trypanosomiasis, transmitted by tse-tse fly bite, is a mainly rural disease and is strongly linked to people's living patterns and conditions, proximity to water-courses, in particular. Although environmental and behavioural risk factors are important in the epidemiology of human African trypanosomiasis, individual sensitivity to the disease appears to exist, according to experimental and immunological studies. IRD researchers investigated the role of human genetic diversity in the resistance or sensitivity to parasitic diseases, including sleeping sickness.

- P(acman) takes a bite out of deciphering Drosophila DNA
11-30-2006 · EurekAlert!
A new method of introducing DNA into the genome of fruit flies promises to transform the ability of scientists to study the structure and function of virtually all the fly's genes, and the method may be applicable to other frequently studied organisms such as mice.
