Will mosquitoes die of heat at 4 1.6℃?

Since late July, Luzhou, Yibin and other places have sustained high temperatures, with the highest temperature reaching 465,438 0.6℃. Affected by this, the mosquito density decreased slightly compared with the same period last year. It turns out that mosquitoes don't like high temperature, which is "hot to death". However, frogs generally grow better than in previous years, and professional frog farmers have a bumper harvest. The person in charge of the Vector Control Department of Luzhou CDC said that if it rains and cools down, mosquitoes may "make a comeback".

Luzhou CDC monitors the density of mosquitoes and other vectors every year. Recent monitoring results show that the activity time and range of mosquitoes have been shortened since the middle and late July this year. "People living in high-rise buildings generally feel that there are no mosquitoes this year, and there is no mosquito-repellent incense for more than 20 floors." Ms. Zhou, a citizen of Luzhou, said that her family lives on the second floor and really feels that there are fewer mosquitoes than in previous years.

According to the monitoring personnel of Luzhou CDC, according to previous years, there will be an obvious peak of mosquito density from late July to early August, but this year's mosquito density has decreased compared with the same period last year. According to expert analysis, the decrease of mosquitoes in southern Sichuan has a lot to do with the weather. "When the temperature is high and there is only a small amount of rain, the breeding rhythm of mosquitoes is disrupted, so there are fewer mosquitoes."

"The most suitable temperature for mosquitoes to survive is between 22℃ and 32℃," the researchers found. "The high temperature above 40℃ is almost fatal to mosquitoes." So the high temperature since late July has killed many mosquitoes.
