When the climate gets cold in autumn and the temperature drops below 10℃, mosquitoes will stop breeding and die in large numbers. Once the temperature is too low, the life metabolism of mosquitoes is also in a very low state, and very few mosquitoes survive. When the temperature exceeds 35℃, people will feel uncomfortable, and mosquitoes will bite people in summer.

The suitable temperature for mosquito growth is 25~30℃. If it exceeds 35℃, people will feel uncomfortable in summer and mosquitoes will bite people. At this time, when the water temperature in the roadside well does not exceed 25℃, it will inhabit and breed there. What makes it more carefree is the bomb shelter, basement and sound well. The temperature in these places is kept at 16~20℃ all the year round, and some can reach 24℃. Mosquitoes generally appear in April every year and reach the peak in the middle and late August.

Outside, mosquitoes usually hide in warm places such as heating pipes, and the mosquitoes that appear in the second year are mostly hatched from eggs.

Blood-sucking habit

Mosquitoes also transmit diseases through blood-sucking. Understanding the blood-sucking habits of mosquitoes can reveal their relationship with diseases.

Only female mosquitoes suck blood, and female mosquitoes must suck blood on the ovaries to develop and reproduce. Female mosquitoes begin to suck blood 2 ~ 3 days after emergence, and many factors such as temperature, humidity and light will affect mosquito's blood-sucking activity.

When the temperature is above 10℃, begin to suck blood; Generally, Aedes mosquitoes mostly suck blood during the day, while Anopheles mosquitoes and Culex pipiens mostly suck blood at night. Some prefer human blood, others like to suck the blood of domestic animals, but there is no strict selectivity, so mosquitoes can spread human and animal diseases.
