When they mate (交配) with female mosquitoes (which do bite), a special gene (基因) stops the female from making female mosquito babies. This means no more female mosquitoes will be born.  So this will stop them from spreading disease.

Further reading

Read the passage and answer the questions.

    We know the mosquito very well. Mosquitoes are everywhere. They can be found all over the world and there are more than 2,500 kinds of them.

No one likes mosquitoes. But the mosquito might decide that she likes you. She? Yes, she. It’s true that male mosquitos don’t bite (咬) and only the female mosquito bites because she needs blood to lay eggs. She is always looking for animals to bite.

 

        If she likes what she finds, she bites. But if she doesn’t like your blood, she will go to someone else for more delicious blood. Next time a mosquito bites you, just remember you are chosen. You’re different from the others!  If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything. After she bites, you will feel an itch (痒) on your body because she puts something in your blood when she feeds. By the time the itching begins, she has already flown away.                         

 

       And then what happens? Well, after her delicious dinner, the mosquito feels tired. She just wants to find a place to rest. There, on a leaf or a wall, she begins to lay hundreds of eggs. (End)
