Male fruit flies can smell a good mate based on her metabolism
A female fruit fly must balance her energy usage between making eggs now and storing nutrients for later. This balance affects the pheromones that she produces and impacts whether male fruit flies find her attractive, report Tatyana Fedina of the University of Michigan and colleagues, Aug. 17, 2017 in PLOS Genetics. (2017-08-17)

The laws of attraction: Pheromones don't lie, fruit fly research suggests
For the first time, scientists have shown that a female fruit fly's pheromone signals can actually tell males how much energy her body has invested in egg production versus in storing away energy for her own survival. And it's a signal that she can't change in order to make herself more attractive. (2017-08-17)

The irresistible fragrance of dying vinegar flies
Vinegar flies should normally try to avoid their sick conspecifics to prevent becoming infected themselves. Nevertheless they are irresistibly attracted to the smell given off by sick flies. A dramatic increase in the production of the sex pheromones responsible for the attractive odor of the infected flies is caused by pathogens: this perfidious strategy is used by the deadly germs to enable them to infect healthy flies and spread even further.

The Oriental eye fly that transmits conjunctivitis newly recorded in China
Some grass fly species are known as 'eye flies' as they transmit conjunctivitis, as well as other eye diseases, to both humans and domestic animals. The larvae feed on feces or thrive in decaying flesh, so they can usually be found in birds' nests, excrement or carcasses. In a paper published in the open-access journal ZooKeys, a team of scientists record four grass fly species in China with three of them new to science. (2017-08-03)

It's not just what you eat, it's what's eating you
Restricting how much you eat without starving has been shown to robustly extend lifespan in more than 20 species of animals including primates. How this works is still unclear. A new study shows that it's not just what or how much you eat that matters. Smelling food in addition to consuming calories could influence the aging process. And, what's 'eating' you or more specifically your cells may provide clues to healthy aging. (2017-08-02)

Cockroach gardeners: Spreading plant seeds across the forest floor
Researchers in Japan have discovered that cockroaches can disperse seeds like birds and mammals. A variety of seed dispersing animals had been identified, including birds, monkeys, ants, and even slugs, but no cockroaches. This unexpected discovery was made during a study of the seed dispersal mechanism of Monotropastrum humile, a small herb that thrives in the same temperate forests of Japan that the Blattella nipponica cockroach inhabits. (2017-08-02)

Can insects be used as evidence to tell if a body has been moved?
The use of insects as indicators of post-mortem displacement is a familiar technique depicted on many crime investigation TV shows. In reality, this practice is far from clear-cut. To cut through the hype, researchers have looked across existing studies to review how exactly insects have been used in legal investigations and to what extent these methods have been useful. (2017-08-01)

How fear alone can cause animal extinction
Fear alone may contribute to the extinction of animal populations according to a recent study. When scientists exposed fruit flies to the scent of a praying mantis, a known predator, they found that the risk of extinction increased up to seven fold. The increased risk of extinction occurred because at small population sizes, as the flies spent more time being vigilant and less time eating, populations that declined could not quickly rebound. (2017-07-24)

Scientists discover combined sensory map for heat, humidity in fly brain
Northwestern University neuroscientists now can visualize how fruit flies sense and process humidity and temperature together through a 'sensory map' within their brains, according to new research. The findings could one day help researchers better understand how the human brain simultaneously processes humidity and temperature and might influence how humans control for mosquitoes in cities and prevent mosquito-borne diseases. (2017-07-20)

Study reveals interplay of an African bat, a parasite and a virus
A lack of evidence that bats are key reservoirs of human disease has not prevented their vilification or efforts to exterminate bat colonies where threats are presumed to lurk. 'The fact is that they provide important ecosystem services...and we want them around,' says Tony Goldberg, a University of Wisconsin-Madison epidemiologist and virus hunter. 'But bats are also increasingly acknowledged as hosts of medically significant viruses. I have mixed feelings about that.' (2017-07-13)

Mapping behavior in the fruit fly brain
One of the primary missions of neuroscience is to make connections between particular neurons in the brain and specific behaviors. Now a team of researchers has used computer-vision and machine-learning techniques in fruit flies to create behavior anatomy maps that will help us understand how specific brain circuits generate Drosophila aggression, wing extension, or grooming. The data are being published July 13 in the journal Cell as a resource for other investigators. (2017-07-13)

Artificial intelligence helps build brain atlas of fly behavior
