Wolbachia is "healthy gut microbiota" but for mosquitoes. It prevents their infection by many viruses.

It seems that it shortens their lives, so it's not healthy for them.

Fine with me, they can be as unhealthy as possible for all I care. Little bastards deserve the worst in life.

The negative is you're disrupting the ecosystem. They reduce the mosquito lifespan's which might impact their population. Things that eat mosquitoes might have to adapt. At this point I'm prepared to accept that though. The suffering these things cause is immeasurable. I hate mosquitoes so much I wish I could nuke them.

More likely, the targeted mosquitoes are outcompeted by other mosquito or small insect species that are just as useful to whatever was dependent on the targets. There's an obvious exception for if some plant is exclusively pollinated by some disease-carrying mosquito, or other bet specific relationship, but that seems unlikely and easy to detect in advance. People in these discussions forget that there are lots of mo…

In fact, there's certain belief in the Scientific community that (human biting, desease spreading) mosquitoes could safely be eradicated from the planet without impacting on the ecosystem.

Singapore has been doing this for years.

When they release new males they put a flyer up at our lift that says "there's gonna be tons of mosquitoes soon, don't worry, they are males and they don't bite" and shortly after, all mosquitoes are gone.

It seems to work. I'm not a fan of meddling with nature in this way, though. I have zero doubts that this will end up in some kind of unforeseen disaster.

N=1, there were a ton more frogs when I was a child, than now.

This is hardly the place for this kind of discussion but I can't help but comment on this. Countless species are already going extinct all the time, both known to us and completely unknown to us, and both "naturally" and from human impact, and no one really cares. Here's a rare case of a species that there is very good reason to deliberately get rid of, and suddenly people care and object, a lot!? Of course there's j…

On this case of the Aedes Aegypti in the Americas, should not even be a big consideration whether to exterminate or not, since it's an invasive species from Asia.

ah yeah I even forgot that super important thing which self-professed environmentalists also always care so much about

it's astonishing that so many of them (not all, but many) are all for keeping all other invasive species in check but somehow make an exception for Aedes Aegypti, literally the most harmful and destructive one :melting_face:

It's the means. If people wanted to look for ways to help reduce stagnant water, as a means of reducing mosquito populations, I suspect exactly 0 people would object. But releasing billions of mosquitos with a bacteria and hoping there's no natural evolution to it, and everything continues to work as planned indefinitely...? There's more than sufficient reason for skepticism there. Beyond this, I would also consider…

> There's more than sufficient reason for skepticism there

there really isn't. it just sounds bad to uneducated laymen - like I said, every expert who studies this, including biologists and environmentalists, agree the mosquitoes can and should be eradicated with zero impact on ecosystems

> It's like how NASA can lose a half a billion dollar probe in modern times because nobody bothered to ensure that all systems were using the same unit systems

this has nothing to do with the subject

> Take yourself a decade in the future and imagine reading about these mosquitoes gaining, at the minimum, a resistance to the bacteria being used. Would it really surprise you? Or would you be thinking something more along the lines of, 'Wow, how could they not see that coming?'

no, the bacteria and/or mosquitoes evolving together is an anticipated outcome and that would surprise absolutely no one. the real question is, when that happens, so what? then we can deploy CRISPR or some other means to extinct the mosquitoes

Starfield companions would've frown upon this solution. More seriously though: 10 years is a long time, this is super interesting but one would wonder if in such time other limiting dengue factors might've arose.

I'm pretty sure this would be their preferred solution. They all get angry at you (and chastise you for not "trusting the science" because in the 23rd century, ecology is not considered science anymore?) for wanting to reintroduce the predator instead of spreading a microbe.

Note that California has reported two cases of Dengue in people who haven't travelled outside the United States.

> The case remains under investigation, but it appears that someone became infected with the dengue virus, returned home and was bitten by a mosquito that passed it on to the local resident, according to Pasadena health officials. https://abcnews.go.com/Health/wireStory/california-officials... It seems part of the common pattern for outbreaks of dengue viral infections in other urban centres. However California lacks…

My personal favorite are the occasional cases of airport malaria.

I can’t help but feel like I’ve heard this before.

How often do you hear about the downsides of malaria eradication in the United States (probably spraying most of Florida with DDT would be one…)? What about screwworm fly elimination in the United States and parts of Central America? That program is much more similar to the thing described in this article than spraying every puddle with insecticide.

Well, widespread spraying with DDT did essentially create a permanent reservoir of DDT-resistant mosquitoes, which also made them resistant to pyrethroids. Bit of a problem. Fun fact - DDT makes spider mites extra fertile.

I do agree however that the eradication efforts of both caused significantly more good than harm, no question.

This is great news. Dengue was a constant problem in my home country of Malaysia, and remains a problem to this day. I still remember all the public education campaigns about it that I saw when I was young (random ads on TV about making sure there's no stagnant water, seeking medical help if you notice , etc), I'm very glad that there are easily implementable solutions to these problems. As a side note, I wonder why…

It is not a funding problem. These countries (ie: Third-world and less developed) never had these research structures in the first place. So they are lacking on guidance on how to execute. A good starting point is to look at government revenues. Indonesia has half the revenue of the government of Belgium. Belgium has less people than Jakarta.
