I'm the only one not comfortable with the idea of wiping whole species just because we don't like them? I mean, I'm far fromthe Gaia thing, but what rights do we have to do that? And next? Rats, cockroaches? Hey, this specie of birds doesn't do anything useful and eat our fruits, why not killing them all?
Mosquitoes aren't even "responsible" for those diseases... Maybe we should invest in proactive body defenses against virus instead of just killing some random things.
Even if we just kill those mosquitoes species you know what? Nature evolves. Other mosquitoes and viruses will come. Do we kill them too?
