there are many wonders in the world. Have you ever seen mosquitoes die of heat due to high temperature? The national high temperature weather makes many people unbearable. We all know that in summer, high temperature will easily breed bacteria, and a large number of mosquitoes will appear. But have you heard that mosquitoes are killed by heat in high temperature weather?
Recently, the high temperature in Sichuan has continued. According to the information released by the provincial meteorological station, the subtropical high pressure zone is on the road again, and the high temperature is spreading rapidly. It will take 7-8 days, around the beginning of autumn, before the basin will have an obvious precipitation process. In Luzhou, Yibin, Dazhou and other places with high temperature, insects and animals such as moving mosquitoes, fish, quail and so on died in large area due to the direct or indirect influence of the hot weather.
Luzhou
High temperature since late July
It's killing a lot of mosquitoes
Since late July, Luzhou and Yibin have kept high temperature, with the highest temperature of 41.6 ℃. Affected by this, the mosquito density slightly decreased compared with the same period of previous years. It turns out that mosquitoes don't like high temperature and are killed by it. However, frogs are generally growing better than in previous years, and farmers of frog industry are enjoying a good harvest. The head of the vector biological control department of Luzhou CDC said that in case of rain and cooling, mosquitoes may return.
Luzhou CDC will carry out vector biological monitoring on mosquito density every year. The latest monitoring results show that since the middle and late July of this year, the activity time of mosquitoes has been shortened and the range has been reduced. 'people living in high-rise buildings generally feel that there is no mosquito this year, and no mosquito repellent incense is needed above the 20th floor. 'Luzhou citizen Ms. Zhou said that her family lives on the second floor and does feel that there are fewer mosquitoes than in previous years.
According to the past years, the mosquito density will have an obvious peak from late July to early August, but this year's mosquito density is lower than that of the same period last year. According to expert analysis, the decrease of mosquitoes in southern Sichuan has a lot to do with the weather. In the case of high temperature and only a small amount of rain, the breeding rhythm of mosquitoes is disturbed, so there are fewer mosquitoes. '
The most suitable temperature for mosquito survival is between 22 ℃ and 32 ℃. 'the researchers found that high temperatures above' 40 ° C are almost fatal to mosquitoes. As a result, the high temperature since late July killed many mosquitoes.
