Their findings about the aerodynamics of mosquito wings could have implications for building quieter drones and for devising nontoxic methods to trap and exterminate the pests.
In a research paper published in Bioinspiration and Biomimetics, a team from the university's Whiting School of Engineering, Rajat Mittal, a mechanical engineering professor, and Jung-Hee Seo, an associate research professor, explain the aerodynamics and acoustics of the mosquito mating ritual through computer modeling.
"The same wings that are producing sound are also essential for them to fly," said Mittal, an expert in computational fluid dynamics. "They somehow have to do both at the same time. And they're effective at it. That's why we have so much malaria and other mosquito borne diseases."
His team's research shows that "everything about mosquitoes seems perfectly adapted for accomplishing this sound-based communication."
"Thus," the paper states, "understanding the strategies and adaptations employed by insects such as mosquitoes to control their aeroacoustic noise could eventually provide insights into the development of quiet drones and other bioinspired micro-aerial vehicles."
In addition to devising quieter rotors for drones, Mittal said the findings will likely inform research into how sound can be used to interrupt the mating ritual. That could result in non-toxic methods to disrupt breeding and diminish mosquito populations.

Mosquito mating flights, and drones? So, we're going to build mosquito sex bots to mate with the mosquitoes so they don't mate with each other? That could be an interesting movie, if we can prevent Hollyweird from taking it over. Mating flights . . . we'll find that on the porntubes?

You misunderstood. Male bees (aka drones) go silent if they hear the mating rituals of mosquitoes. :-)

So, voyeurs then? They like to watch, but can't perform?

Mating cats can be so loud that they keep waking you up, but I've never been bothered by mating drones.

That could be arranged.

Mating foxes aren't quiet either...
...and when you live in a house in a (mostly) natural amphitheatre favoured by sex mad vulpines...and mating season is rapidly approaching...and, thanks to freaky acoustics and luck, your house is close to the focal point for reflections of any sounds generated in said amphitheatre..
No quiet nights for me for a while...insomnia's a bitch.
