The monitoring data of Hunan Provincial Center for Disease Control and Prevention over the years show that the density of mosquitoes has two peaks every year: late spring and early summer and late summer and early autumn. At this time, there is a lot of rain and the temperature is between 25 and 35 degrees Celsius. It is mosquitoes. The optimum temperature and humidity for growth.

is a member of the insect family. Mosquitoes live in water before they grow wings. They spend three stages of egg, larva and pupa in the water. Different types of mosquitoes live in different types of water.

When the summer is the hottest, there are fewer mosquitoes. Analyzing the specific reasons, on the one hand, the water body is reduced due to the evaporation of the water surface, and the breeding grounds for mosquitoes are significantly reduced; on the other hand, the environment of high temperature and high humidity is not conducive to the growth of mosquitoes. The rise drops rapidly, and adult mosquitoes may also enter a quiescent or diapause state with no or less blood-sucking.

Save "energy" for the winter, mosquitoes in autumn are more biting

There are more mosquitoes in autumn, why are they biting more? Experts analyze that autumn is also the breeding season for mosquitoes. In order to allow their offspring to get better nutrition, mosquitoes in the breeding period will be more ferocious and bite people more severely, which is why the mosquitoes are particularly poisonous in autumn.

In addition, after the beginning of autumn, the temperature drops, the rain increases, and the mosquitoes regain their vitality. In order to reproduce the species, they must prepare for winter before winter comes.

Depending on the species, mosquitoes either accumulate enough food for the winter after feeding and sucking blood, or lay enough eggs to survive the winter with eggs, or the eggs hatch into larvae and survive the winter as larvae . In either form, the first step is to suck blood. This is also the reason why everyone thinks autumn mosquitoes are powerful.
