That would be great if they found a solution for the fucking mosquitoes and malaria. But I think a whole bunch of animals and insects feed on mosquitoes and that may screw up the equilibrium of nature....Try to go fishing up north during springtime its crazy they are all over and thick.

A population of the world's most invasive mosquito species was almost completely wiped out by an experiment on two islands in the southern Chinese province of Guangdong, according to a study published Wednesday.

The experiment successfully reduced the female Asian Tiger Mosquito population -- the main source of bites and disease transmission -- by up to 94%, reducing the number of reported human bites by 97%.
It isn't the first attempt by researchers to reduce mosquito populations across the world. In 2018, scientists from the Imperial College of London used gene-editing tools to render female mosquitoes sterile, while males developed normally and continued spreading the genetic mutation.
One of the Chinese study's researchers, Xi Zhiyong, a professor at Michigan State University, has been a longtime pioneer in this field of study. Running a mosquito factory in southern China, he previously attempted to use sterilized male mosquitoes to mate with unaltered females.
"We're building good mosquitoes that can help us fight the bad ones", Xi told CNN in 2016.

In the new study, published by the International Journal of Science, Xi and his colleagues attempted to cut mosquito numbers even further by limiting both male and females' ability to reproduce.
Female mosquitoes were sterilized with low level radiation while the males were infected with the Wolbachia bacteria, then both were released during the peak breeding seasons in 2016 and 2017 on two islands near Guangzhou city.
The results were so successful they nearly eradicated the entire female mosquito population on the two islands.
In a statement, mosquito ecologist Peter Armbruster said the trial was one of the most successful mosquito reduction trials to date given mosquitoes' stubborn survivability.
Experts said the Asian tiger mosquitoes are particularly hard to eradicate using conventional population control methods, such as pesticides and removing stagnant water where the insects lay their eggs.

The white-striped mosquitoes have been described as "highly invasive" and have spread from Asia to almost every continent over the past 40 years, according to the study's authors.
Mosquitoes pose grave threats to human health beyond just irritating bites. The World Health Organization (WHO) has described the insects as "one of the deadliest animals in the world," due to their ability to rapidly spread deadly diseases such as dengue fever and malaria.
Guangzhou, a densely populated urban metropolis with a tropical climate, saw around 37,350 people infected with dengue fever during an outbreak in 2014.
This month, Philippines health authorities declared a "national dengue alert" after more than 450 people were killed by the virus in just the first half of 2019.
There is currently no effective vaccine or treatment for most mosquio-transmitted diseases, leaving controlling the insects' populations one of the most effective control methods, according to the International Journal of Science.
"A new tool like what's being described in this paper is very much needed," Dobson said.

You nailed it. I can't believe there is yet a human alive who knows enough about what makes nature work to go meddling on that scale. The Greeks called the impulse hubris, and it always ends badly. Not that we should stop the first experimenters; the trick is when to have the wiser heads step in.

And who gets to pick those wiser heads.

We should start do research like this here, as it seems mosquitoes invasion gets worse over the years!

they should do the same for other pests like bed bugs, termites etc etc..

I think the lefties will argue "don't mess with nature".
I take it you didn't read Zai's intro closely; he pretty much put the gist of this actual real-world topic in his first couple of sentences.

Here, we read a guy devoting his brain-power into guessing at what people might say, that he's already decided he disagree with. For political reasons.

No thoughts of your own? The pattern's tedious and the political-rationale is stretched really thin. A lefty position on mosquitoes?

I dunno about eradicating mosquitoes, but I live near a swampy area and this year the mosquitoes are murderous. Maybe reducing their numbers without eradicating them would be OK?

More frogs, less mosquitoes. The problem is with more of the sun's ultra violet rays reaching the ground, frogs are being culled.

Yeah, wiping out mosquitos would be bad. I am by no means pro-mosquito, I will very resoundingly say fuck those things, but I think what needs to happen is to find a way to stop them from biting us, not eradicating them. I don’t know if it’s a pheromone, or an injection, or something that masks the CO2 trail that attracts them to us, but that’s the way to go. Mosquitos are little bastards and I hate them, but so many animals rely on them as a food source. You knock the bottom out of the food chain, there are going to be serious repercussions all the way to the top. Many other insects feed on them, frogs, lizards, bats, spiders, birds, even some rodents and fish. They’re horrible creatures, but they’re absolutely essential to the ecosystem.

Bats apparently eat hundreds of mosquitoes an hour and eat about 1200 insects an hour...

Many bats, and almost all in the United States, thrive on an insect diet. A single bat can eat up to 1,200 mosquito-sized insects every hour, and each bat usually eats 6,000 to 8,000 insects each night.Their appetite for mosquitoes certainly makes a backyard more comfortable. Bats are opportunistic, and their lack of discretion benefits everyone. Some of their favorite prey include crop-destroying moths, cucumber beetles, flies and gnats. Natural insect control is their specialty.

This year, the mosquitoes are winning.
