Why are there so many mosquitoes before a thunderstorm or on a sultry day?

The chemotaxis of insects is the reason why there are so many mosquitoes before a thunderstorm or on a hot day. When the weather is hot or the humidity in the air is high, human skin will secrete many compounds containing amino acids, lactic acid and amines, thus attracting mosquitoes and making them follow people. Some entomologists have found that the tentacles of mosquitoes are very sensitive to carbon dioxide and can gather.

Mosquitoes are really annoying. Have you noticed that the weather is usually sultry and there are many mosquitoes before a thunderstorm? Today, I'll tell you why.

0 1 before the thunderstorm, there were many mosquitoes because of the chemotaxis of insects (that is, insects have a certain tendency or avoidance reaction to some chemicals with special odor). When the weather is hot or the humidity in the air is high, people's skin will secrete many compounds containing amino acids, lactic acid and amines. These wastes can't volatilize quickly because of sultry heat, but they can trap mosquitoes, so that they can follow people.

Recently, an entomologist found that the tentacles of mosquitoes are also very sensitive to "carbon dioxide" and can smell it with the wind. This explains why there are so many mosquitoes near people in the sultry days before the thunderstorm.

However, some volatile substances can repel insects. Working people in our country have long known that lighting mosquito-repellent incense or burning mugwort leaves can repel mosquitoes. Therefore, mastering some unique chemotaxis of insects can be used to repel pests; Or add some attractants it likes to pesticides to make the pest control effect more obvious.
