How fruit flies ended up in our fruit bowls
Fruit flies can be a scourge in our homes, but to date no-one has known how they became our uninvited lodgers. For decades, researchers have searched for their origins and now a Swedish-American research team has succeeded. They have also discovered that fruit flies in the wild are far more picky than their domesticated counterparts, a factor that long ago probably prompted the flies to move in with people.

Tiny fruit flies use cold hard logic to select mates
Fruit flies -- the tiny insects that swarm our kitchens over the summer months -- exhibit rational decision making when selecting mates, according to research published today in Nature Communications. Researchers observed different combinations of fruit flies mate about 2,700 times, and were surprised to discover that male flies almost always pick the female mate that would produce the most offspring. The study provides the first evidence that fruit flies are capable of making rational choices. (2017-01-17)

To kill off parasites, an insect self-medicates with alcohol
Alcoholic drinks aren't generally put into the category of health food, but in some cases they might be just the cure for nasty parasites. That's according to a study published online on Feb. 16 in Current Biology, a Cell Press publication, showing that fruit flies will actually seek out alcohol to kill off blood-borne parasitic wasps living within them. (2012-02-16)

Has a possible new lead been found in the fight against neurodegenerative diseases?
Good communication between brain cells is vital for optimal health. Mutations in the TBC1D24 gene inhibit this process, thereby causing neurodegeneration and epilepsy. Fruit flies with a defect in Skywalker, the fruit fly variant of TBC1D24, are being used as a model for neurodegeneration. Researchers from VIB and KU Leuven have succeeded in completely suppressing neurodegeneration in such fruit flies, by partially inhibiting the breakdown of 'defective' proteins in brain cells. (2014-11-24)

Those fruit flies are pickier than you think
On your kitchen counter, it might seem as though fruit flies will show up for just about any type of fruit. But when given a choice about where to lay their eggs, those flies will go for citrus most of the time, new work shows. A new reports shows the basis for that seemingly complex food preference is simple. It boils down to a single odorant receptor found on a single class of sensory neurons. (2013-12-05)

Fruit fly helps reveal the secrets of the fragile-X-syndrome
The fragile-X-syndrome is one of the major causes of mental retardation. Scientists from VIB (Flanders Interuniversity Institute for Biotechnology) have been studying fruit flies with symptoms similar to those in humans. From this research, it turns out that something goes wrong with the actin skeleton of the neurons in the brain. This process might also take place in human patients with the fragile-X-syndrome − an important step in uncovering the physical background of this disorder. (2005-06-20)

Neither nature nor nurture: Behavioral individuality in fruit flies' neurodevelopmental origin
While some fruit flies wander, others prefer to walk the straight and narrow; the origin of these behavioral quirks in individual flies may be a product of random variation in how neural circuits are wired during brain development, a new study of fruit flies given 'lines to walk' finds. (2020-03-05)

Thanks, fruit flies, for that pleasing beer scent
The familiar smell of beer is due in part to aroma compounds produced by common brewer's yeast. Now, researchers reporting in the Cell Press journal Cell Reports on Oct. 9 have discovered why the yeast (formally known as S. cerevisiae) make that smell: the scent attracts fruit flies, which repay the yeast by dispersing their cells in the environment. (2014-10-09)

Flies on speed offer insight into the roles of dopamine in sleep and arousal
Methamphetamine, the drug of choice for long-distance truckers and college students pulling all-nighters, appears to do a similar trick for fruit flies, too. This finding is one of several in a new study that demonstrates a critical role for the neurotransmitter dopamine in the modulation of sleep, wake, and arousal states. (2005-07-11)

Bacteria may not hasten death
Get rid of bacteria or let the body fight them. In flies, it's a wash. Flies scrubbed clean of bacteria did not outlive their dirtier siblings, according to a new study in Cell Metabolism that challenges the conventional view that bacterial load taxes an organism. (2007-08-07)

The buzz on fruit flies: New role in the search for addiction treatments
Fruit flies may seem like unlikely heroes in the battle against drug abuse, but new research suggests that these insects -- already used to study dozens of human disease -- could claim that role.

Their study appears online in ACS Chemical Neuroscience, a new monthly journal. (2009-12-02)

Fruit flies learn from others
Fruit flies do not always conform to the norm. When female fruit flies have to decide where to lay their eggs, they take their lead from what they see most others in their group do. However, some do take their personal preferences into account. So says Marine Battesti of the Université Paris-Sud in France, lead author of a study in Springer's journal Behavioral Ecology and Sociobiology. (2014-11-17)

By examining fruit flies' brain activity and behavior, the researchers found that deep sleep has an ancient, restorative power to clear waste from the brain. This waste potentially includes toxic proteins that may lead to neurodegenerative disease. (2021-01-20)

Flies that 'stick' upside down landings use different approach than thought
Researchers studying one of the least understood aerobatic maneuvers performed by flying insects, and who call their investigation the 'most complete exploration of fly landing maneuvers' to date, report that blue bottle flies that land upside down on ceilings use a more complex series of behaviors than thought. This insight will inform efforts to engineer small robotic fliers to perform similar aerobatics, the authors say, and it can also be applied to the field of neuroscience, where it could lead to new hypotheses for understanding how insect brains function. (2019-10-23)

Fruit fly steps in to fight human disease
VIB scientists have successfully introduced genes coding for a variant of the Charcot-Marie-Tooth (CMT) disease, into fruit flies.

Fruit flies unlock Methuselah's secrets
Research published in Genome Biology investigates genes that increase the life span of fruit flies in an effort to gain a greater understanding of the ageing process. The researchers from the University of Southern California and Harvard Medical School screened 10,000 fruit fly populations that were mutated. Their results revealed that six populations of mutant flies lived 5-17% longer than normal and that the extended life span was caused by the overexpression of six different genes. (2003-01-30)

Invasive flies prefer untouched territory when laying eggs
A recent study finds that the invasive spotted wing drosophila (Drosophila suzukii) prefers to lay its eggs in places that no other spotted wing flies have visited. The finding raises questions about how the flies can tell whether a piece of fruit is virgin territory - and what that might mean for pest control. (2021-02-15)

Freeloading orchid relies on mushrooms above and below ground
The orchid species Gastrodia pubilabiata mimics rotting mushrooms or fermented fruit, and is pollinated by fruit flies who mistakenly lay their eggs in its flowers. If there are rotting mushrooms near the orchid, its pollination rate increases. As well as using mushrooms to attract insect pollinators, G. pubilabiata survives by absorbing nutrients from the fungal hyphae of mushrooms. This is the first time a plant has been discovered to depend on mushrooms both above and below ground. (2018-03-22)

Why so fly: MU scientists discover some fruit flies learn better than others
Fruit flies could one day provide new avenues to discover additional genes that contribute to a person's ability to learn and remember.
