We've separated the males from the females.

If there's a male mosquito that you release, and if there's a female around, that male will find the female.

A mosquito

And lakes with fish have more mosquitoes, even though they eat them.

If they don't find a female, then they'll die anyway.

I hate mosquitoes.

And mosquitoes.

A mosquito bit me

If you put more sterile males out into the environment, then the females are more likely to find a sterile male than a fertile one, and you will bring that population down.

And the second is a phenomenon that males are very, very good at finding females.

It nearly goes away in the dry season, because there's no place for the mosquitoes to breed.

I got bitten by mosquitoes.

It's only the female mosquito that will actually bite you.

It's just the female.

Malaria is carried by mosquitoes.

I have brought you a few little things.

Now there are two features of mosquito biology that really help us in this project, and that is, firstly, males don't bite.

Flies and mosquitoes interfered with his meditation.
