Network video display

A boy made a "oh" sound outdoors

Many mosquitoes gathered in front of him

Then he tried it repeatedly with this method.

Some netizens speculate that the principle

It is called mosquito to judge "prey" based on carbon dioxide

When the boy is posting "Oh" sound

It will discharge a large amount of carbon dioxide in the body

But some netizens refute

"So do my legs often distribute carbon dioxide?"

Some netizens shared their childhood experience:

"The sound of‘ oh oh oh oh ’can be summoned to summon many mosquitoes

Isn't this common sense when we were young?

Adults still stop us when we see us like this

It is said that mosquitoes are poisonous and do not let us fight with our hands

I don't know what the specific principle is

It is estimated that the sound audio can be received by mosquitoes

Then they were gathered together "

In this regard, Jimu Journalists asked for advice

Zhou Xingmiao, Associate Professor of Insect Studies in Huazhong Agricultural University

He said that this is a normal phenomenon

Because mosquitoes can feel low -frequency sound

Outdoor mosquitoes are generally active in space below 1 meter

Feel the frequency of the sound between 350 and 550 Hertz

Children emit "O" sound

Just meet these two conditions at the same time

Therefore, the phenomenon of mosquito gathering in the video

And the audio and height of people usually speak

Both have exceeded the above two conditions

Therefore, there will be no mosquito phenomenon

"The specific part of many insects

There are auditors that feel sound waves ""

Zhou Xingmiao further introduces

This type of hearing device is called "Jiang's device" in academic majors

It was discovered as early as 1855

The mosquito itself will also make a "buzz" low -frequency sound

They heard the low frequency of "O" gathered

It's not surprising
