Love Songs of Mosquito

Lu Xun said in his famous article "Xia San Zhe": "Fleas come to smash blood, although it is abominable, and it is a bit of a sound, how straightforward and refreshing. Mosquitoes are not, a needle into the skin, naturally can be considered a bit thorough But before the attempt, I have to send a big argument, but it makes people feel annoyed. If what is wrong is to explain the reason why human blood should give it hunger, then it is even more annoying, but fortunately I am not understand."
   
People who are disturbed by mosquitoes in the summer night can easily resonate with this, but this is a bit of a mosquito. The mosquito is not the one who likes to talk about it, or wants to be upset, but is involuntarily. Mosquitoes also prefer to be silent, because the snoring exposes the whereabouts of the mosquitoes, and people are prepared. Many mosquitoes die from this snoring.
   
But this is not something that mosquitoes can control. The snoring is not from the mouth of the mosquito, but is caused by the rapid vibration of its wings during flight. Compared with its flies and cockroaches, the sound is too small to be small. Mosquitoes are one of the fastest insects in their wings. They can beat 600 times per second, while small mosquitoes can reach up to 1000 times per second. The mosquito's wings are very narrow and can be maintained at a certain speed by rapid vibration. Conversely, the wings of flies, baboons, and bees with wings larger than mosquitoes vibrate less frequently than mosquitoes, about 250 times per second, while the wings with much larger wings vibrate at a lower frequency, only about 30 per second. Times. The snoring of these insects is also the sound of the wings vibrating, because the wings are larger, so it is much louder than the mosquitoes.
   
Although the snoring of mosquitoes is a by-product of the vibration of the wings, it is extremely important for the reproduction of mosquitoes. Entomologists have long discovered that male mosquitoes are looking for a spouse by monitoring the snoring of female mosquitoes. Putting the female and male mosquitoes into the same small cage, the easiest way to make them mate is to shake the cage and let the mosquitoes fly: the vibration of the wings when the female mosquitoes fly will stimulate the male mosquitoes to mate with them.
   
Male mosquitoes are so obsessed with this sexy voice, even ignoring what is emitted. The experiment found that hitting the tuning fork outside the cage of the male mosquito, in a certain range of sound frequencies, will attract the male mosquito to fly in the direction of the tuning fork, grab the gauze covering the cage and try to mate with it. Many people have had this experience, talking in the wild, talking and talking suddenly a mosquito flew into the mouth - it must be a male mosquito, it thought that there is a female mosquito hidden in your mouth. Mosquitoes flying in the wild at dusk are male mosquitoes. If you talk, or lick a song, you will attract them around you. Don
