Release of 750M GM mosquitoes gets approval

The experimental release of millions of genetically modified mosquitoes has been given the go-ahead.
The questionable endeavour, which will see around 750 million of the insects released in the US state of Florida, has been condemned by environmentalist groups as a 'Jurassic Park experiment'.

The insects, which have been bred by British-based biotechnology company Oxitec, have been designed to help reduce the mosquito population in the state and in so doing, reduce the risk of spreading deadly diseases such as West Nile virus and St. Louis encephalitis.

The key to the experiment lies in having the mosquitoes carry a certain protein which, when passed down to female offspring, will prove lethal. Only female mosquitoes actually bite, so by selectively reducing their numbers, scientists hope that the spread of disease will be massively reduced too.

With the release of the insects now greenlit by local authorities, the experiment will begin in 2021.
The mosquitoes will be released in the Florida Keys.

"The release of genetically engineered mosquitoes will needlessly put Floridians, the environment and endangered species at risk in the midst of a pandemic," environmental group Friends of the Earth said in a statement in response to the news.

Oxitec, meanwhile, argues that there is no risk and that this isn't the first such experiment.

"We have released over a billion of our mosquitoes over the years," said one scientist. "There is no potential for risk to the environment or humans."

I immediately thought of this.

Good point.    I still swat any I see though.

Reducing the mosquito population shouldn’t negatively affect the bird population, and could actually reduce bird mortality caused by West Nile Virus. The birds will relocate to another area, the mosquito population will eventually rebound due to the reduced bird population, and then the birds will return. It’s a temporary fix, but if it works, and WNV is temporarily eradicated, then it’ll be worth the effort.

yep, nature is a complicated things, might get rid of mosquitos in a small area, but on a state scale, bad idea,  we actually did plant plants that attract dragonflies around our summer house,  it worked somewhat, we did see a bit more dragonflies,  a bit less mosquitos,  but no night and day difference, still got bitten,

Genetically altering one of the worst pests in history... What could go wrong? Just what we needed "Super skeeters"

So what do they eat?

Just when we all thought it couldn't get much worse than covid in 2020

Just like how radiation doesn't make Fallout style super mutants and ghouls, genetic manipulation like this doesn't make super mosquitoes. There's nothing to panic over. This will either help, or have no measurable effect. People really need to stop getting their science from sci-fi. It's almost as bad as anti-GMO food people and anti-vaxxers...

For anyone actually interested in the mechanism of how this is supposed to work, here is a quote from Oxitec.
