As for the concerned Conchs, they have little or no power to stop the plan if it's approved. Even if they fill a petition with signatures and persuade the City Council to pass a law against mutant mosquitoes, the public health authority granted to the Keys Mosquito Control District trumps the power of the city. Biddle, the former dengue patient, doesn't necessarily want to stop the plan from going forward; he just wants independent, peer-reviewed assurance that Oxitec mosquitoes are safe.

"[Oxitec] should have to do a five- or six-year study in the Cayman Islands and see what really happens," Biddle says. "What are the effects on people? What are the effects on tourism? What are the effects on the disease? And what are the effects on the ecosystem? That's what we should be studying. And still, without these findings, we're going to put something in the Florida Keys that's genetically modified, and we don't know what's going to happen."

Doyle is afraid that it will take another outbreak of dengue fever for people to see the wisdom in his plan. "I'm optimistic that it will happen someday," he says. "But I think nothing will happen until there's some external push to make something happen, like if we see dengue again."

While he and Oxitec wait for a federal yea or nay, Doyle does his best to assuage the concerns of people like Biddle and local lawmakers who remain opposed to the idea. A recent survey among Keys' residents found that 30 percent supported it, 30 percent were against it, 8 percent were unaware, and the remainder were undecided. If those numbers shift and the majority turns against the project, Doyle hints that he will still push ahead.

"My job is to protect them," he says, "even if sometimes they don't want to be protected."

I completely agree with the above comment, the internet is with a doubt growing into the most important medium of communication across the globe and its due to sites like this that ideas are spreading so quickly. Thank you for the article. I just about passed your blog up in Google but now I'm glad I clicked the link and got to read through it. I'm definitely a little better informed now. I'll be sharing your site with some other people I know. They'll get a kick out of what I just read too.

DEATH TO THE MOSQUITOS! The Dengue Virus is a Terrorist that invades cells and Hijacks the cell's ribosomes to make copies of itself that will go on to invade/hijack other cells. This Virus has potential to be transfered to a different species including Homo sapiens. www.youtube.com/watch?v=YDRRKA8CJHk .The goal is to stop cell division and PREVENT these creatures from transmitting this horrible Virus to other species. Dengue is Deadly, and Oxitec holds the patent on this amazing tool to lower the population of Aedes aegypti mosquitoes, generation by generation. The FDA is setting an example for the world, and must not disappoint.

It's so scary and I'm so stupid.  A terrible combination.  Let's have a study.  A real big, long and expensive study with lots of Phds and bureaucrats.  I don't care how many people die in the mean time so long as it isn't anybody in my family, then I'll sue the shit out of everybody who might have a dollar.

Can someone give me an example of previous geo/bio engineering that had greater benefits than the eventual risks? This is a real, almost non-snarky question. On the bad side we have, rabbits in Australia, dams stopping salmon, snakes in Hawaii... Seriously give me one example of relatively harm free bio engineering please. Also, I wonder how far this UK company would get releasing GM mozzies in their home country.. ?

There are several cheap, effective and environmentally friendly alternatives to GM mosquitoes.  Native plants that repel Aedes aegypti like American Beautyberry can be used as screening to reduce the House Index.  A study using repellent plants in Tanzania reduced all mosquitoes found in houses by 50%, the cost was $1.50 per house which includes maintenance and labor costs.  This can be used with attractants and lethal ovitraps using used coffee grounds or other cheap environmentally friendly larvicides, as well as fan traps on the lethal ovitraps to not only reduce the larvae survival but also catch the adult females.  This push pull method may not only reduce the larvae from surviving, but unlike GM mosquitoes will also target the adult females and reduce the chance of Aedes aegypti entering the home, and at a fraction of the cost.

Other methods include the use of some strains of the fungi Beauveria bassiana and Metarhizium anisopliae which some peer reviewed studies suggest can also reduce the survival of Aedes aegypti offspring, but unlike GM mosquitoes can also cause mortality in the adult females, thus reducing both the population and the chance of being bit.

Yet another example is use of the bacteria Wolbachia, which some peer reviewed studies suggest may reduce the adult Aedes aegypti lifespan by 50% and unlike GM mosquitoes may actually provide resistance against dengue serotype 2 and chikungunya.  There are several other alternatives as well.

What mosquito control has failed to mention is that releasing millions of GM mosquitoes including thousands of females could potentially increase the risk of transmitting mosquito-borne diseases.  Releasing millions of male mosquitoes may also increase the risk of chikungunya which a peer reviewed study suggested can be spread when Aedes aegypti mate.  With each male mating as many as 21 times in their lifetime that is a huge risk not worth taking unless the adult female lifespan is significantly reduced or there is resistance against chikungunya, which doesn't appear to be the case for GM mosquitoes.  There have been over 100 cases of chikungunya reported in the U.S. between 2006 and 2009 including cases in Florida so this a very real risk.  Florida entomologist Walter J. Tabachnick, estimated that if an outbreak that occurred in Italy had occurred in Key West it would have caused 1,200 cases of chikungunya and 4,000 cases if it occurred during tourist season.  The Beauveria bassiana and Metarhizium anisopliae alternatives both reduce the lifespan of the adult female and therefore reduce the chance of chikungunya spreading, they can also be used without releasing more males but instead infecting the already existing males and/or females.  The Wolbachia alternative may reduce the lifespan of adult female Aedes aegypti and may even provide resistance against chikungunya, so even if more males were released there would be a significantly reduced risk of spreading chikungunya compared to GM mosquitoes.

There are numerous unknows such as whether or not the synthetic protein based on sequences from E.coli and the Herpes simplex virus that the GM mosquitoes express could be transmitted to humans during a bite or affect animals ingesting them.  As well as a partially independent lab reporting 15% of the GM mosquito offspring surviving in the presence of chicken found in cat food and a member of the mosquito control district admitting that Aedes aegypti have been found breeding in pet dishes, making such an event likely if GM mosquitoes are released.  Along with Florida Medical Entomology Laboratory's Phil Lounibos stating there is no supporting background evidence that GM mosquitoes would solve a dengue problem.  All of this and more makes a GM mosquito release seem like an expensive, pointless and potentially risky proposal.

Mosquito Control does not even have permits for aerial spraying of pesticides.  Check that fact.  They are irresponsible and ignorant.  I don't trust them for a minute, and I don't trust their plan for releasing genetically modified Mosquitoes.

paranoid? Do they require a permit? Perhaps you would like the mosquitoes back and render South Florida uninhabitable? Did you get a permit to post this comment?
