Larvae of fruit flies develop in moist areas where organic material and standing water are present. The common fruit fly (Drosophila melanogaster) is known for its ability to reproduce rapidly. The first step in addressing a fruit fly infestation is the destruction of their feeding and breeding grounds. If there is no fruit or vegetable matter in your kitchen, check your garbage and recycling bins.
Fruit Fly FactsDrains should be the initial inspection site when encountering an infestation. A million tiny fruit flies live in the laboratory of Sergey Nuzhdin, professor of biological sciences at the USC Dornsife College of Letters, Arts and Sciences.
The flies are not (thankfully) buzzing around the room but safely contained in small glass vials — thousands of them. Nuzhdin and his team refer to this room as “The Flybrary.” It provides the raw material for their experiments using flies as models to study genomic analysis of social behavior. Working closely with Paul Marjoram, associate professor of research in preventive medicine at the Keck School of Medicine of USC, Nuzhdin is a staunch advocate of increasing cross-departmental collaboration between USC Dornsife and researchers on the Health Sciences Campus. Thanks to a Research Collaboration Fund award from the USC Office of Research Advancement led by Randolph Hall, vice president of research, Nuzhdin and Marjoram have received grants totaling $4.2 million to study the social behavior of flies as a model for complex behavior in humans. Nuzhdin, Marjoram and their social behavior team use a variety of methodologies, ranging from traditional observation to high-throughput sequencing and automated tracking. Through the lens of a powerful microscope, senior postdoctoral researcher Julia Saltz observed a group of fruit flies interacting on a mixture of sugar, agar and dead yeast, which replicates their natural diet of rotting fruit. Researchers use fruit flies because they can create genotypes — cloned groups developed by inbreeding. Marjoram and Foley are developing computer technology to track and annotate behavior and interactions between flies. Saltz and Foley’s research demonstrates that a fruit fly’s genetic makeup influences the company it keeps. Their research provided proof for the first time that this grouping according to social preference, known as social niche construction (SNC), has a genetic basis.
Nonaggressive genotypes should not be considered “broken males,” Saltz said, pointing out that the flies were pursuing “an alternate social strategy,” which brought them mating success. The team is also examining emergent properties in social systems, in which they create mixed societies using different genotypes by forcing aggressive and nonaggressive males to go into their preferred and nonpreferred group size and observe how they function.
Foley translated this into human terms by giving the example of someone who was constantly rejected in high school, who thus tends to be shier and more socially awkward in the outside world. The team also researches how genetics plays a role in deciding whether to stay or to leave social groups. Marjoram and Foley are writing software to analyze how different genetic profiles result in varied decision making. The team’s research shows how genetic variation is maintained in populations by comparable processes, which allow different genotypes to be equally successful. Research in humans has shown that genotypes influence friendship choices, a process that has been implicated in the development of substance abuse.
By observing the behavior of flies, Nuzhdin and his team hope to find answers to those questions. Nuzhdin paid tribute to Saltz and Foley, the senior post docs he co-appointed with Marjoram. Saltz and Foley’s research has been recognized with an article in Science Daily, while a research paper they authored was named Best Student Paper by The American Naturalist. Nuzhdin also noted his team’s collaboration with USC Dornsife’s Simon Tavare, holder of the George and Louise Kawamoto Chair in Biological Sciences and professor of biological sciences, and his group. Ardekani developed several tracking tools and methods for studying animal behavior, including the social behavior of Drosophila. Back in The Flybrary, a particularly aggressive male was so busy chasing several rivals around the petri dish that he left the female unattended. Using the system of colored dots, Saltz tracks and records the behavior of the tiny fruit flies.

Like other fly species, fruit flies experience a four-stage life cycle: beginning as eggs, they undergo larval and pupal stages before emerging as adults.
Fruit flies often lay their eggs in rotten fruit and other soft, sweet, organic materials. Fruit flies may also use unclean drains as breeding grounds. Outdoor drains are likely sources of yard-based fruit flies, as are overripe fruits beneath the trees from which they have fallen. Although eradication may require several treatments, the lack of food available to fly populations will eventually cause them to die out. Bleach can sometimes be effective; although it is rarely stays in the drain long enough to address the accumulated slime that attracts fruit flies. The flies are used by Professor Sergey Nuzhdin and his team to advance our understanding of whether behavior is determined by genetics or by social environment. Major support came in two recent grants from the National Science Foundation and the National Institutes of Health, aided by the National Institute of Mental Health. Given that the fruit flies are so tiny, the researchers mark them with different colored dots to indentify them and track their behavior.
A red X shows flies are engaged in social interaction, including courtship behavior and aggression between males. This allows scientists to study their behavior in a way that, for obvious reasons, is not possible with human subjects. Nuzhdin’s team hopes that computer tracking will help them unlock the secrets of fly courtship and determine how less aggressive males are still successful in courting females. They found that genotypes differ in their social preference between joining smaller or larger groups, with aggressive males preferring smaller groups and nonaggressive males opting for larger groups. So the ones that care the most are also the ones that are affected the most,” Saltz explained.
It also helps us understand how interaction between our genetic makeup and the social environment determines our behavior. This is impractical with humans, who interact primarily in one social environment, making it impossible to separate whether social environment affects behavior or whether behavior affects choice of social environment. They include Reza Ardekani, who recently earned his PhD in computational biology and bioinformatics, former research assistant Anurag Biyani and PhD student Mohammad Abbasi Dezfouli.
Tavare, Ardekani and Biyani created software combining computer vision techniques and statistical analyses to enable tracking of individual fruit flies while in groups.


A less aggressive male spotted his opportunity and successfully approached her, beginning a slow courtship dance by vibrating his legs on her head. However, Saltz says that after staring at them in the lab for five years, they don’t look so small to her anymore.

But if you happen to be a young fruit fly, it turns out that alcohol can be just what the doctor ordered. All comments must follow the NPR.org Community rules and terms of use, and will be moderated prior to posting. A work of the United States government, as defined by United States copyright law, is 'a work prepared by an officer or employee of the U.S. The early life stages span approximately a few days and fruit flies can complete their development in as little as week in ideal temperature conditions.
The rapid life cycle allows researchers to study the effects of an experiment over a number of generations. If you identify a fruit fly infestation in your kitchen, dispose of all over-ripe or damaged fruit.
While not effective at eliminating an infestation, fruit fly traps may provide temporary relief by trapping some of the adults. One of them appeared to temporarily forget the female as he switched directions to head off his rival.
The numbers next to each fly show coordinates used to track its movements on a grid, while blue dots chart their position.
But today I took it out to the backyard to test out the macro capability and I was very impressed. Schlenke found that if the fly larvae drink the alcohol, they can actually kill off the wasps developing inside them.
NPR reserves the right to use the comments we receive, in whole or in part, and to use the commenter's name and location, in any medium. The mature larvae of fruit flies crawl out of the breeding material to pupate in a dry nearby spot. However, fruit flies are also capable of breeding in decaying meat, trash bins and large spills of soda or alcohol. Any subsequently purchased fruit or vegetables should be kept in the refrigerator until the fruit fly infestation dissipates. They sometimes are mistaken for cockroach or rodent droppings but can easily be differentiated by a pair of horns on one end of the pupae. Fruit flies have only four pairs of chromosomes: three autosomal pairs and one pair that determines sex. Regularly wipe counters, clean spills and empty your trash cans to help prevent fruit fly infestations.
Apparently unimpressed with this display of male virility, she turned her back on him before flying away.
Do they purposefully consume alcohol once they're infected, in order to kill those wasps living inside of them? He says since fruit flies lay their eggs on rotting, fermenting fruit, the larvae that hatch can sometimes find themselves swimming in alcohol. No, they don't start slurring their words and hitting on that cute firefly at the end of the bar. And in this case that substance is alcohol." Self-medicating exists all over the animal kingdom. Insects, birds and primates all have been known to eat special plants to rid themselves of parasites or other ailments. But, says Schlenke, this is the only situation that he knows of that has critters using alcohol as a medicine. They can't stand upright, and they can't perform their normal functions, which is to lay a bunch of eggs in fly larvae and try to complete their life cycles," he says. After all, we get our share of parasitic diseases, too a€” everything from hookworm to malaria.
He's also president of the Sabin Vaccine Institute, which develops vaccines for parasitic infections.
