I can't help it feel that more effort will go into mitigating Zika if adult males are at risk.

Zika should receive more attention if we discover it now affects all adults and not just a minority of them. That's reasonable.

(If your point was about male privilege/priority then I don't disagree, but I don't think it's necessary to read that into this situation because the number of both male and female adult lives Zika could impact may have just grown enormously.)

I'm guessing it's along the lines of "Zika seems to only affect pregnant women, I'm either A) not a woman or B) not planning on getting pregnant any time soon, this will all be over by then."

Zika has a number of neurological and other impacts on adults, as well as its impact on fetuses.

> Zika has a number of neurological and other impacts on adults, as well as its impact on fetuses.

The effect on adults is not yet fully known (hence the OP!). This was just the first study on the topic.

You don't even need to kill all mosquitos, just the ones that bite humans and carry disease. South America actually did manage to nearly eradicate Aedes aegypti, though the success was short lived. Aedes aegypti is not even native to South America- it's African. So eliminating it from the New World can't do that much damage given that the ecosystem got along fine before it arrived.

> Aedes aegypti is not even native to South America- it's African. So eliminating it from the New World can't do that much damage given that the ecosystem got along fine before it arrived. This logic may have been applicable way back when the first few Aedes aegypti made their way to the New World, but at this point, so much has changed in our New World, and we don't really know all the ecological changes that Aedes…

I'm aware of that possibility, but their main niche seems to be sucking human blood and passing diseases around. Other mosquitos feed on other animals and plants, but A. aegypti really loves to eat people.

Perhaps, but I don't believe anyone has demonstrated that mosquitoes have this crucial in impact to he health of the ecosystem. In fact, the aforementioned Nature article explicitly argues against that idea, though obviously it's only a sample size of 1.

This is of course a mouse study, on mice bred to have an immune deficiency to Zika. Immediate extrapolation to humans is a little premature.

I've taken to scanning the NHS's page analyzing health news stories. It's a very useful antidote to potential sensationalism: they go to the original source and summarize it fairly clearly.

So, I know disrupting ecologies can have profound consequences that aren't obvious ahead of time, but let's do a thought experiment. Let's assume we have a 100% effective way to kill all mosquitoes within 18-24 months. What are the known disruptions and consequences of this? Do we have ways to combat problems due to that? What are the probable/theoretical distuptions and consequences? Do we have have to combat these?…

Beyond your question of ecological impact of killing all mosquitoes, as others mentioned they don't all need to be killed.

Historically, South Florida engaged in annual mosquitoe controlling campaigns. Essentially aerial spraying during the Summer. These were stopped because of the budget cuts related to the collapse of the Florida housing market.

Not only did the mosquitoes become intolerable, but before Zika we had a breakout of mosquitoe transmitted Dengue fever. Moreover, the historical mosquitoe controlling never killed all mosquitoes but the were effective in preventing breakouts like Dengue Fever and Zika.

Yeah, we humans are so good at making animals extinct. I can't believe we haven't done that with human-biting mosquitoes (or other nasties) a long time ago. It is time to do that; nature will find a way without the buggers.
