Nothing feels more like summer than a neighborhood barbecue, especially after a dreary winter. But the nemesis of the summer rally remains, that is, the whine of mosquito Around us ear.
Why do these blood-sucking insects circle our ears in the first place? And why are they creating such annoying flows?
“Most of the buzzing in your ears is just a side effect of the mosquito’s wings,” says Michael Riehle, professor of entomology at the University of Arizona.[The sound] It doesn’t have a long range, so you will most likely notice it when they fly close to your ear.

That lady’s lunch
The buzzing sound you hear most likely comes from a female mosquito. That’s because male and female mosquitoes have very different lives. Men tend to hang out and sip on the nectar of flowers. They couldn’t be less interested in the humans cutting down trees. However, the female must find bloody food after mating to have enough energy to produce the egg. In fact, female mosquitoes have a special tool for their next victim.
“From a distance [female mosquitoes] The carbon dioxide we exhale is a funnel-shaped plumage from our bodies, “Riehle told Live Science.” Carbon dioxide encourages female mosquitoes to start looking for hosts to fly back and forth to chase that concentration back to the source. “
In other words, mosquitoes will buzz around our heads because that’s where we expel the most carbon dioxide.
As she approaches the female mosquito absorbs body heat and carbon dioxide lands on the victim. A female mosquito uses a taste sensor on her feet to determine if a human or animal is bleeding enough to touch her next meal. As some studies point to Group O As vintage at its best, Riehle remains skeptical.He hasn’t found convincing research into mosquitoes’ blood type and interests. But he believes that other factors such as people Genetics And even diet plays a greater role in how people are “delicious”
Your skin is power “It gives a unique cocktail scent, which is more attractive to mosquitoes than any other,” says Riehle. Another study It was found that female mosquitoes attracted fewer males with a wider variety of bacteria on their skin than men with a more diverse skin bacteria. These blood suckers are also part of those who wear darker clothing like black.
When the female flies toward her target, she performs about 500 wingspan dancing per second at a frequency of 450 to 500 Hz.This frequency hits the musical note A, incidentally, something the orchestra adapts to itself before the concert.
While it sounded like a high-pitched drone to us. But it is music for male mosquitoes In fact, the winged male Hit with a higher frequency Over the females, listen to the dull tone of the female when they’re looking for a friend. Riehle likes to show this effect to her students by sending a sharp fork over A over the female mosquito cage. On every test, the women did not respond, he said. The same demonstration on the cage of male mosquitoes set their wings on fire as they frantically search for the goddess who created those sweet vibrations.
While male mosquitoes are ferocious with this tone But humans are not very excited to hear it. But while we may immediately recognize mosquitoes that buzz around our ears, Riehle noted that most mosquitoes do not attract to our heads. But these blood-suckers may be more likely to seek our feet, the odor-giving bacteria that seduce mosquitoes. However, most people may not even notice mosquitoes buzzing around their ankles, he said.
1996 study in the journal Parasitology trends It was found that female mosquitoes from the genus Anopheles mosquitoWhich is responsible for sending files malaria The parasite attracts bacteria to the feet of the human being. Brevibacterium beddingIt’s the same kind that gives Limburger cheese its distinctive flavor. A 2013 follow-up study in the journal PLOS One Confirm that mosquitoes are, in fact, attracted to Cheese Slim Burger.
For avoiding mosquitoes, your best option is to wear light and long colored clothing, apply insect repellent, and avoid mosquito spots. (Such as wetlands) at dusk and dawn, when mosquitoes are most active. Live Science previously reported..
