> The approach has succeeded at the scale of cities. In a randomized trial in Singapore, releases of Wolbachia-infected males cut mosquito populations by 85 percent compared to control areas and dengue infections by roughly 70 percent.
(mosquitos infected with Wolbachia are both more resistant to diseases, and fail to reproduce in the case of infected male x uninfected female)
There are different things you can do to mosquitos with different techniques. The article discusses several different techniques. Some eliminate disease-spreading mosquitos, some eliminate the mosquitos. In Singapore, the latter was tried out. It is not the case that Singapore used chemicals.
Get a 5 gallon bucket, add water/grass/leaves/dunk and let it sit for a few weeks. Every few weeks add more dunks. Put a stick in there so small animals don't get stuck when trying to get a drink.
Does anything eat them as food? Wouldn't it be environmentally damaging to remove a source of food for X?
Joking aside, the consensus seems to be that the effect of removing disease-carrying mosquitoes (not all mosquitoes) from the environment is minor compared to how many lives it can save.
(I don't know what the Amazonian frog eats; my point is that biotopes are complex and second- and third-order effects need to be monitored. That's why smaller interventions - e.g. making humans poisonous to mosquitoes, pushing them to the evolutionary path of avoiding humans - would be better than whole eradication.)
We could in one stroke take half of what multi-billionaires and quasi-trillionaires have hoarded. If they didn't have personal accountants, they wouldn't even notice it, as they have far more money than what they manage to burn through - and we would have the means to "choose" to solve real problems affecting hundreds of millions of people.
A gene which incurs a fitness cost will be purged from the population under selection!!
I agree they are a nuisance but they do not exist on their own. Many of them spend their time feeding on plants rather than blood.
Bill Gates is involved in this. Always a red flag.
Anyway since they kill north of half a million folks yearly and infect couple of hundred millions as official minimums, I am more than happy with some other species of small insects take their empty spot. Of course not everybody cares much about poor folks dying quietly half around the world, but some do. One of very few benefits of global warming is the migration of these bastards more north so rich folks in US and Europe will have more personal stake in this topic rather than usual 'oh that's so horrible, next'.
Some minor re-adjustement of ecosystem is more than fine, anyway we do it constantly for rather pathetic reasons if any. I would add ticks, all forms, to the effort.
The population of an endangered Australian bat suddenly dropped by up to 16%. No one knows why

People like the author actually belive that there is no chance of real world interactions happening.
Eg what is the bacteria jumps to some other organism? What if it mutates? What if the birds eat the mosquitoes and carry a mutated bacteria elsewhere?
There is a reason why you need autistic level safety for such projects, and even then things like this might happen.
It's completely impossible to guarantee theses things, no matter how long you study it in a lab.
Some people just aren't capable of thinking more than 1 step ahead.
I completely disagree. This is a reasonable and responsible timeline to look for unintended consequences. Some things, you simply cannot undo.
What if the bacteria (somehow) jumped to monarch butterflies and killed them off? Controlled releases and multi-year environmental studies are the correct and responsible course of action. In fact, when the injected insects are released into an area, the entire thing should be monitored carefully, as each ecosystem might respond differently.
All of that being said, excited to see this adopted more broadly. It's time these fuckwit insects die.
In general, you have to weigh the irreversible cost of unintended consequences with the irreversible cost of known human death from mosquitoes.
Is your level of knowledge on this just "there are other things called mosquitos ergo it's not a problem," or do you have deeper affirmative knowledge that the animals that eat these mosquitos also eat those other mosquitos, and that those other mosquitos can increase their population to replace the lost food source?
If it took a couple hundred years for this species to proliferate, it's absolutely plausible that eradicating it in a few years will have surprising second- and third-order effects.
I'd be much more concerned about the changes humans do to our ecosystems that we know cause harm, but aren't stopping (like filling the atmosphere with CO2 and other greenhouse gases) than about changes that would, almost certainly, reduce harm and have only extremely unlikely and hypothetical risks.
I agree that many of the risks are hypothetical, but I disagree that we can simply dismiss them. Taking a decent amount of time to understand cause and effect on ecosystems seems like a perfectly prudent thing to me.
Growing up my sister got dengue, so I hate mosquitoes, she was fine, I know dengue was no joke, but I always worry we make too many assumptions as humans, only to be proven wrong by nature somehow.
It has been used to suppress screw worm in the United States for decades until the administration cut the funding.
These are almost always a temporary solution that need constant funding and seasonal releases to work. The populations will surge back as soon as it's stopped.
If it's one-and-done, everywhere on Earth (eg smallpox), it can work. If it drags on for decades or isn't rolled out globally (eg malaria) then it won't work.
This is at best a temporary solution.

It's been nine years since that blurb was updated supposedly.
Or do you reserve most of your concern for just the few species of human disease-carrying mosquito?
Kind of a genuine question, because I've observed over the years people popping in to this topic to exclaim deep concern for the potential ecological impacts of intentionally extincting a couple of species -- that most biologists reportedly agree aren't keystone species. Meanwhile, species loss continues to occur globally for a variety of reasons and yet it's still really difficult to get the average person to care very much about that.
The psychology here is peculiar and I don't understand it.
Many such comments are very dumb, asking 'and how do you feel about viruses, screwworms, etc.?', but since you say this is a genuine question: mosquitoes are numerous and we know that they represent a source of food for many species (bats, birds, other insects). As far as I know, there is genuine debate among scientists about the role that mosquitoes play in their ecosystems. Everyone here has seen species of animals and plants eradicated and then being reintroduced or replaced, when we realise what role they were playing.
Again, assuming you're asking in good faith: you're asking why these commenters are so concerned while humanity is eradicating species all the time anyway: these are not the same populations... I'd wager there is a big overlap between those wondering about consequences and those taking action for the planet (not eating animal products, not flying, etc.). Similarly, I'd wager there's overlap between those posting such illogical retorts, and those eating animals at every meal and driving their car daily.
I see the same ridiculous retorts in HN debates about the condition of animals.
There's an excellent book on the impact of the mosquito on humanity, and a brief overview of some of that subject here: https://www.newyorker.com/magazine/2019/08/05/how-mosquitoes.... These species of mosquito are and have been one of the most significant threats to human health for all of our existence.
I don't think argument-from-ignorance should be more convincing here than it would be on any other subject. There is some debate among researchers, sure, but published biologists have been making arguments in favor of eradication for over 20 years (https://www.nytimes.com/2003/09/25/opinion/a-bug-s-death.htm...). If someone is being intellectually honest in objecting to this on the grounds of the fragility of ecosystems, then they must also be an equally loud voice against the use and manufacture of glyphosate. That one chemical alone is already having a far greater impact on insect populations, yet you can buy it at your local hardware stores.
So yeah, I genuinely don't understand the reasoning here. It feels like a dumber version of the trolley problem, where a perceived inaction that has far larger negative consequences is preferable to an action with more limited ones -- except in this case, it's not even right to describe our current impacts on ecosystems as "inaction".
I suspect that if an article were published tomorrow that found that, through some previously-unknown mechanism, the expected rise in global temperatures over the next 10 years would have a side-effect of killing all mosquito populations, that article wouldn't even make the front page of HN. Nobody much would care, aside from those few recurring voices mourning our future.
More cynically, I also suspect that since the worst impacts on human health are occurring in tropical populations, westerners find it much easier to argue in favor of protecting this particular pest.
I'm not versed in everything with all these species, but I believe everything has a purpose, look if someone goes all out into mosquitoes and proves they had absolutely no purpose, I'll concede, I just think its worth studying these types of things. For example, some years I fight wasps near my house, then the following year, I'm fighting fire ants. If I don't eradicate one or the other, they show up the next year, every year I fight one or the other, I assume they compete with one another. I wish I could curb stomp both from ever coming back, fire ants make me bust out with sores all over, however, I know me killing them from my lawn / property isn't killing ALL of them.
Well, what would come out of the outback once the rabbits are gone? Since we know the state of Australian wildlife before the rabbits, the answer is "nothing".
If there's an abandoned lot and you eradicate the mosquitoes by removing the water filled abandoned car tires, the existing ecosystem does pretty well. In a similar way you can willfully decide to make a livestock pond either a mosquito factory or mosquito free and mosquito free has not resulted in any problems.
Local eradication programs have successfully worked for centuries, at least. What makes this story interesting is its very wide ranging and likely very expensive.
(aside: There are lots of visible downsides to lots of local eradications of lots of things)
> this effort is interesting because it's much less local
So in other words it's very different from all the success cases you're alluding to?
Would an alien species contemplating the eradication of wheat be correct to think "that won't hurt Homo sapiens much, wheat makes up <1% of our taxonomic category 'things that grow in dirt!'?
