While it may seem that all mosquitoes are biters, this is not actually the case. Male mosquitoes eat plant nectar. On the other hand, female mosquitoes feed on animal blood. When a female mosquito bites a human being, it transmits (传播) saliva into the blood. This saliva may or may not contain a deadly disease. The result of the bite can be minor or as serious as death.

Because a mosquito can bite many people in its life, it can carry deadly diseases from one person to another very easily. More than 700 million people become sick from these diseases every year. At least 2 million of these people will die from these diseases.

In some households, mosquito nets are placed over beds to protect people against being bitten. Mosquitoes have many natural enemies like bats, birds, dragonflies, and certain kinds of fish. Bringing more of these animals into places where mosquitoes live might help to cut down the number of mosquitoes in that area. This is a natural solution, but it does not always work very well. Mosquitoes can also be killed with poisons or sprays. But these sprays may also harm other plants or animals.

Although mosquitoes may not seem as scary as larger, more powerful animals, they are far more dangerous to human beings. But things are changing. It is highly likely that one day scientists will find a way to keep everyone safe from mosquitoes and the diseases they carry.
