The part of the mosquito's wing pictured above, is what makes the buzzing or whining sound. Both male and female mosquitoes buzz, since they both have wings, but you probably won't notice the whine of the males, because they don't want to drink your blood. Scientists have discovered that the buzz of mosquitoes is more than just a way to annoy you.
By the middle of the 20th Century, scientists had figured out that mosquitoes have special organs to whine or buzz as they fly, that other mosquitoes can hear the noise, and that the buzz of female mosquitoes makes males want to mate with them. It wasn't until more recently that researchers Gabriella Gibson and Ian Russell discovered that mosquitoes actually change their buzz to "sing" to each other before they mate. As scientists learn more about why mosquitoes buzz, they may be able to use that knowledge to help keep them from mating. Cornell researchers have found out that mosquitoes not only buzz in your ears, they buzz in each others' "ears" too, as described in the video below.
Mosquitoes can turn a beautiful backyard or patio into a nightmare, and keep you from enjoying the barbecue or pool or just the back-porch swing.
All articles and comments are the opinion of the authors, and we cannot guarantee the accuracy or the currency of the information. With the Zika drama now being played out upon the global stage, the spotlight is being trained on the story’s villains, namely the hordes infected mosquitoes that are spreading the disease at such an alarming rate. While this is good news for people who worry the Zika outbreak will make its way here, Cloutier says the outlook might not be as sunny for our neighbours to the south. A distant cousin of Aedes aegypti, the Aedes albopictus or Asian tiger mosquito, is more adapted to northern climes and is already well established on the Eastern U.S. More importantly, there are any number of weapons in our arsenal to help control the growth of mosquito populations. Another effective tool is to release thousands of genetically modified males into a population.


McGill’s Student Health Service  has a special notice about Zika, with links to public health websites for more information. It did work in the summer,with the rains and more and more mosquitoes,the patch is of no good at all.
The Electric Bug Zapper Flying Insect Killer uses ultraviolet black light to lure light-sensitive flying insects into an electrically charged metal grid, destroying them quickly.
The comb-like half, shown in blue, scrapes against the part shown in yellow, whenever the mosquito flaps its wings. Christopher Johnston of Baltimore, Maryland had already discovered how mosquitoes can hear, almost a hundred years before. Though you hear the buzz whenever mosquitoes fly, it's not actually caused by the wings beating against the air. They discovered that when males and females flew nearby, they altered the pitch of their buzz to match each other, and if they matched well enough, they mated. Chris Cloutier, McGill’s resident mosquito expert, says the Aedes aegypti species is pretty much nature’s perfect virus delivery device, which is why it came by its common name, the yellow fever mosquito, honestly.
For starters, while Zika can have a catastrophic impact on unborn children, the virus is relatively benign for the vast majority of people who contract it. Chemical insecticides are among the cheapest and most effective ways to put a large, initial dent in the mosquito population. The offspring of these genetically modified males carry a deadly gene that kills off larva before they become adults.
Any small pool of standing water is a potential breeding ground for mosquitoes, meaning people have to take charge of their immediate surroundings.

Dead insects collect in a tray at the base of the electronic killer unit, which can be easily removed for cleaning and replaced for another round of bug collecting.


He found that they have an organ in their antenna, which was named the Johnston organ after him. There's an organ at the base of the wings which scrapes and makes the sound when the wings move. Cornell researchers tried the same experiment with mosquitoes which carry the dangerous disease dengue, and found the same thing. For example, in this article, researcher Lauren Cator suggests that if scientists can make sterile male mosquitoes who "sing" to females just as well as fertile males, the females will choose the sterile males, and won't produce fertile eggs.

But, unlike many species native to Canada, Aedes aegypti, can neither survive our winters as adults (Cloutier says a number of Canadian species actually winter in homes and garages) nor do they lay frost-resistant eggs like their northern brethren. When they circle your head, looking for a place to land and bite, their buzz sounds louder whenever they're close to your ear. We may sometimes complain about our winters but they are natural barriers for many potentially problematic species. Army during World War II, noticed that males ignored females whenever the females were quietly resting, but whenever the females were flying, and therefore buzzing, the males wanted to mate with them. The males even wanted to mate with recordings of female mosquitoes or tuning forks that vibrated at the same pitch.
Shipley and Edwin Wilson published a paper describing it in 1902, which they called "On a Possible Stridulating Organ in the Mosquito." Stridulating means to make noise, and the toothed organ they found made noise as it rubbed against itself, while the wings moved.
