Ok, so why isn't this ACTUALLY being done?
California is being absolutely inundated by invasive mosquitos from China. They're a proper scourge. Absolutely awful, and they're everywhere in huge numbers.
Some company recently withdrew its application to do this kind of sterile single generation mosquito population control program. I can't find any valid reason why.
They're invasive. They don't belong. Why WOULDN'T the government want to eradicate them locally?
