Here’s what I’m missing in all these discussions:
There are a zillion species of mosquitos. Insect-killing pesticides are a problem because they tend to kill all kinds of insects, from mosquitos to ants to houseflies to honeybees. Or, if you could develop a pesticide that was very mosquito-specific, it might be very hard to restrict it to killing only these two species that carry dengue/malaria/chik-unspellable/zika. And furthermore, they’d develop resistance quickly enough, just like insects have always done.
There’s all this talk of GM mosquitos or irradiated mosquitos, where they raise a swarm of defective males and release them. What are the problems with this? These techniques would be highly specific to just those two species targeted, not even attacking all the other species of mosquitos. And, as far as I can picture, this isn’t something that they bugs will develop an immunity to.
If we can exterminate just these two species, how ecologically bad could that be? There are plenty of other species of mosquitos for the bats to eat.
