In the past, it was difficult to go out without getting bitten by mosquitoes, especially in southern China, where people were constantly harassed by this blood-sucking insect. Before summer in 2022 comes, many people had mosquito-repellent drugs ready as usual, only to find out that they didn’t come in handy. Why is that?
According to an expert from the Hangzhou Center for Disease Control and Prevention, mosquitoes are very active when the ambient temperature is between 26 C and 35 C. However, recent extreme weather in southern China often reaches more than 40 C. Such high temperatures have led to a sharp drop in mosquito populations, the reason being that they stop laying eggs and often die of heat.
Such high temperatures have led to a sharp drop in mosquito population. Some southerners have mixed feelings of hoping to cool down as soon as possible but not wanting mosquitoes to return. One of the most popular comments read: “Don’t mention mosquitoes, above 40 C it’s also hard for me to survive.”
