Should Zambia Allow The Testing of Genetically-Modified Mosquitoes? (nhregister.com)
More than 400,000 lives are lost every year to malaria, reports the New York Post. But Thursday Science published two new studies on promisings ways to fight malaria -- with genetic engineering.
The first study focused on whether mosquitoes that have been genetically modified to be more resistant to the malaria-causing parasite would become weaker and less able to mate and breed... The study, led by mosquito vector biologist George Dimopoulos, found that one type of genetically modified mosquito not only bred well, but became more attractive to normal mosquitoes... Within one generation, the mosquito population was becoming 90 percent genetically modified... The results suggest the genetically modified mosquitoes would not just thrive but could possibly drive their genetic immunity to the malaria parasite into mosquito populations to which they are introduced.
The second study published Thursday uses genetic modification of bacteria found inside mosquitoes to fight malaria. Researchers genetically modified a type of bacteria, which caused it to secrete a substance inside the mosquitoes' gut that kills off the malaria-causing parasite before it can develop properly... the genetically modified versions of the bacteria automatically spread to offspring in generation after generation, the researchers found. The next step for both approaches -- the genetically modified mosquitoes and bacteria -- is to test if they work outside the lab in conditions simulating nature. Johns Hopkins has built a "mosquito house" research facility in Zambia designed specifically for such experiments... But the researchers must first convince the Zambian government to allow their genetically modified subjects into its borders.

This is exactly what the world is worried about and already seeing in some ways from GE crops.
The problem is not opening the box but closing it.
There's nothing in TFS or TFA to suggest they shouldn't or that they won't. Just that they've never decided on something like this before.
As always it depends very tightly on the genetic modification. In this case mosquitoes resistant to the malaria bugs so it can not longer live them and hence be spread via those mosquitoes, sounds pretty safe. Obviously the mosquitoes are happier as they are thriving and out breeding unprotected people, people might not be as happy because still noisy irritating mosquitoes, healthier ones but at least no malaria. Well, you can't have everything.
Chaos - everything, everywhere, everywhen
Folks, we have been playing god for a few millennia by now. Earlier with selective breeding, now more directly. The difference is negligible. And when it comes to the "unnatural" argument... well, look at a Chihuahua and then talk again.
And introducing "foreign" genes doesn't make it any different. These genes are just like everything else built by the four standard amino acids. With a different sequence than most of what you found in the original organism, granted, but in the end, what exactly is that supposed to mean?
What we need to watch out for is how genes interact with each other. But that's something we can identify pretty quickly. Aside of that, what exactly is the big scare?

You first might want to check what species rely on them for food.

That's not a feasible solution. You'd be killing off a lot more that mosquitos, you'd kill entire eco-systems that feed on them.
Anyway, they are mosquitoes! What are the chances that they haven't escaped in the wild yet, like in any sci-fy movie?

any mosquito species is the easiest species to replace - there are so many of them, and we could even eradicate all the blood-sucking mosquitoes and just leave those that don't.
In fact, a mosquito species can even be replaced by entirely different families (i.e. not from Culicidae):
Yet in many cases, scientists acknowledge that the ecological scar left by a missing mosquito would heal quickly as the niche was filled by other organisms. Life would continue as before — or even better. When it comes to the major disease vectors, "it's difficult to see what the downside would be to removal, except for collateral damage", says insect ecologist Steven Juliano, of Illinois State University in Normal. A world without mosquitoes would be "more secure for us", says medical entomologist Carlos Brisola Marcondes from the Federal University of Santa Catarina in Brazil. "The elimination of Anopheles would be very significant for mankind."

Mosquitos are just the vector.
Maybe we should release a GMO Home Sapiens that's more resistant and less able to mate and breed instead.
WRT mosquitos in the food chain, wouldn't it be possible to simply break the Malaria cycle?
Once there's no Malaria to spread Anopheles populations could be allowed to recover. There's no reason (other than hating mosquitos) to eradicate the whole species. Or even try.
Malaria has been eliminated in Europe and North America – by draining swamps and spraying. Are there really no more Anopheles left in those parts of the world? There are certainly plenty of other mosquitos left.
One thing that has been shown in multiple countries is if you reduce the childhood death rate, fertility goes down. People no longer have large families, because the are pretty sure the first few will survive. It is when parents have to assume that some of their children will die of disease that they have large familes, just in case.

The malaria mutates so it can infect the GE mosquitoes, slowing down reproduction of the GE mozzies. The End. So worst that could happen is that it doesn't work. Most likely cause of this is not being able to do a wide enough release, so there is a mixture of GE and non-GE mozzies, alowing the Malaria parasites to develop resistance before they are eliminated.
So, in short, no small-scale limited releases just to make sure!

And we have been doing this for ages. The only difference is that before, we had no idea what we were doing. We looked for random changes caused by cosmic rays etc. in living things; we even put seeds under an X-Ray (or beta, or gamma-rays) to make random changes in the genetics; or we cross-bread two different plants, producing a random mix of genes that often was not viable of itself,but we could harvest the germ and make it grow outside the seed.
All this we do, and they even get to call the results of this random, uncontrolled gene editing 'organic'.
The difference is that now, we are making single changes that we have an ability to know and predict the results of. This is a much, much safer form of genetic modification than what we have been doing for centures.

400,000 people a year say do it!
You confuse it with the fictional world of Narnia.
Zambia exists.
It would be more interesting to see if the Malaria parasite would adapt and become resistant to the gene modified mosquitoes. I would prefer to get rid of the mosquitoes totally unless they are made by de Havilland.
If builders built buildings the way programmers wrote programs, then the first woodpecker would destroy civilization.
Mosquitoes are a food for a good part of our ecosystem. They even are pollinators, for our crops. As well one of the core parts of the food chain. Killing them off could be a disaster.
We just need to find a way for them not to attack humans or our livestock and spread pathogens then we are fine.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
People in big European cities don't care about ... AC.
Are you sure about that? What about these people?
Ah, that's right, they don't care about anything anymore, as they're dead.
And, please, before you point out that this was so long ago, way back in 2003, and thus not relevant or important, do at least try to remember that people might want to turn the air conditioning on before the temperature gets hot enough to kill...
In the UK, the temperature does not go beyond 30 for more than a couple of days a year.
How people can die of heat is beyond me.
Wouldn't a two child policy be better?
Yes, population will keep rising for a while, but it will someday reach a 'stable-ish' level. If we go to a one child policy, we'll have an 'old-heavy' population soon AND the policy will have to be changed someday anyway.
Well, there isn't really a requirement that an organism must serve a purpose. I mean, what's the purpose of human, to ruin the game for the rest of the players?
By that logic, we shouldn't celebrate the elimination of smallpox...

So what happens when malaria evolves in to something worse because of this?
Good one!!
It would be more like scary, than interesting to me!
Well Dragonflies eat their weight in mosquitoes every night. We have mosquito abatement projects in our neighborhood. End of Dragonflies. :(
You are right! They pollinate small flowers. And do other things, which if forgot..
like maybe Isla Nublar?

Testing in production is always a good idea
First of all, all you folks who said they need to test it in a controlled environment, that's been done out in the open, on North America. Second, obviously they should only do it if the individuals making the decisions get bribed well enough. This is some really dangerous shit. A mere $10k bale of US Benjamin's is not enough to turn a blind eye or say nothing to the press. You need a million. Maybe ten.

People in big European cities...
In the UK...
While you are quite correct about temperatures in the UK, I think that this is what's referred to as moving the goal posts.
Most mosquitoes don't bite humans, they pollinate crops and plants instead. Killing them off would harm us.
That's an average temperature, not the maximum. You could have a local spike up to 50 C, and roofers and pavers would experience higher temps too. Surviving high temp is more about having water and shade than anything else, so in rich countries only the elderly and the homeless would fear it.
The article I was replying to specifically mentions people dying in the UK, among others.
My first thought was that such tests should be done on an island....but then an early post said that Florida was already testing GM mosquitoes. If that's correct, then, unless this is a different modification, I guess they might as well go ahead.
One proposal I heard was to modify mosquitoes so that they were immune to malaria, but I doubt that's far enough along to be practical.
I think we've pushed this "anyone can grow up to be president" thing too far.
Humans exist to feed rodents our trash. Their populations would collapse without us.
This space intentionally left blank
The Earth can sustain more that 7 Billion people right now, because the population is still increasing.
Long Answer: Nooooooooooooooooo, because: Letting big companies test genetically altered stuff in a third world country is just wrong.
I suspect that people who are against all GMOs don't know what they're talking about. This is also true about people who are for all GMOs.
Farmers buy GMO seed and plant it. It's been tested, and will produce useful crops. It's always possible that something will go wrong, but that could be handled by destroying the crops in a limited area, without much other harm. Harmful mutations will be limited.
If someone releases GMO mosquitoes or bacteria, we're much less sure of what might happen. The mosquitoes or bacteria might mutate in ways they otherwise wouldn't have. There may be harmful environmental consequences, since we're not releasing them into a monoculture of limited size. If everything works as intended, this isn't a problem. If something goes wrong (and many more things can go wrong than with GMO crops) how do we get rid of the mosquitoes or bacteria?

He's been under IRS audit for 20 years. Give it a rest, you're not going to find anything. Just like with Russia - NOTHING! Well Nothing on Trumps behalf. We've found plenty of collusion with Obama and Hillary and Russia. Even the fact Obummer hid the hacking from everyone even though he knew it was going on and even made fun of Trump for saying it could be hacked. We also found out that Hillary was given about 500K from the Russians and she gave them a bunch of Uranium. Just google Hillary Russia Uranium. It'll pull up the NY Times story on that.
