There are more than 2,000 species of mosquitoes in the world, and there are about 140 species in China. Mosquitoes that can transmit diseases can be divided into three categories: one is called Anopheles mosquitoes, commonly known as malaria mosquitoes, which mainly transmit malaria.
The other group is called Culex mosquitoes, which mainly transmit filariasis and Japanese encephalitis. The third group is called Aedes mosquito, which has black and white markings on its body, also known as black spots, and mainly transmits Japanese encephalitis and dengue fever.
