My first thoughts on seeing the URL: That's a fantastic, super geeky domain name.

I would love to see the complete eradication of these pest species; what a great effort by said Alphabet team.

It doesn't really explain though. Are the sensors detecting something chemically unique to males / females? Or are they taking images of each mosquito and differentiating between them with ML?

I believe one way is to generate a frequency similar to female wingbeat frequency that attracts male mosquitoes and separate them that way. I am unsure if there is a difference in the frequency between genders.

There absolutely is a difference in sound. If you hear a mosquito, it's female. Males are silent.

This is how the photo fence from intellectual ventures detects and destroys female mosquitoes.Unfortunately they never released that tech as open source

Lesbian mosquitos...hello?

As long as they're inclined to seek out females in the wild and spread the mosquito STD, they could be just as useful as males :)

There's some margin of error, and it would be interesting to see what that is, tbh.

Does no one remember Jurassic Park?

Yes; Scary movie.
