Why are Chongqing mosquitoes so poisonous?

The reason why Chongqing mosquitoes are poisonous is related to their reproduction speed and chemotaxis.

The high temperature and humid air in Chongqing provide good breeding conditions for mosquitoes. In such an environment, mosquitoes breed very quickly and in large numbers. As the temperature rises in summer, the human body sweats more and bacteria tend to breed on the skin surface. When mosquitoes bite the human body, the toxins in their saliva will trigger an inflammatory reaction, leading to local discomfort such as redness, swelling, itching, and pain, and even allergies and poisoning.
