First Genetically Modified Mosquitoes Released In the United States (nature.com) 89

A biotechnology firm has released genetically modified mosquitoes into the United States for the first time. Long-time Slashdot reader clovis shares the report via Nature: The experiment, launched this week in the Florida Keys -- over the objections of some local critics -- tests a method for suppressing populations of wild Aedes aegypti mosquitoes, which can carry diseases such as Zika, dengue, chikungunya and yellow fever. [...] Aedes aegypti makes up about 4% of the mosquito population in the Keys, a chain of tropical islands off the southern tip of Florida. But it is responsible for practically all mosquito-borne disease transmitted to humans in the region, according to the Florida Keys Mosquito Control District (FKMCD), which is working closely with Oxitec on the project. [...] In late April of this year, project researchers placed boxes containing Oxitec's mosquito eggs at six locations in three areas of the Keys. The first males are expected to emerge within the first two weeks of May. About 12,000 males will exit the boxes each week over the next 12 weeks. In a second phase later this year, intended to collect even more data, nearly 20 million mosquitoes will emerge over a period of about 16 weeks, according to Oxitec. "There is the usual opposition of the 'It's GMO, so it should not be done' variety," adds clovis. "As for ecological food chain considerations, one should know that aedes aegypti is not native to the western hemisphere. It is believed to have been imported from Africa during the slave trade era."

          Only five mosquito species transmit human diseases. If we went farther and eliminated all 200 species that bite humans, there would still be 3,000 species left.

            That's an incredibly confident statement to make when you have zero knowledge of the potential impact of that change. Do you really think that other species aren't bitten by those mosquitoes? Do you really think that the deaths those mosquitoes cause in said species has no effect on the ecosystem as a whole?

          Mosquitos, yes. Aedes aegypti, the one specific invasive species, that actively hunts humans, and carries most mosquito-borne human disease? Not so much. From TFS:
          >Aedes aegypti makes up about 4% of the mosquito population in the Keys,

          Wipe out that species, and the many native species will rapidly expand to fill that niche. In fact, so long as the displaced native species still exist (and breeds quickly), wiping out pretty much any invasive species tends to result in overall health of the ecology improving rapidly.

          And since this GMO mosquito does NOT use gene drives, and simply renders the half-breeds unviable, the risk of it significantly affecting other species of mosquito is vanishingly low.

          Other groups have developed gene drives that make all descendant's male in perpetuity - which would far more effective at eradicating a species, but come with a large risk of spreading across species (interspecies breeding does occur, and a heavily male population increases those odds), potentially eventually wiping out all species of mosquito in the world. *That* would be a problem.

          But thankfully those plans have not yet gotten permission to proceed... at least in the US. The prospect of gene drives being released elsewhere worries me. With malaria killing a half-million people a year, many hard-hit places might be far more interested in a quick and effective, one-time, permanent solution. And by the time the problems started appearing it would be far too late to do anything about them.

          • by v1 ( 525388 )

            I've read about gene drive development to insert a protein that stops the malaria cycle. It doesn't do anything else. And since the mosquitos don't benefit from malaria (and probably are harmed by it in a very small way) it seems like an ok thing even if it spreads farther than intended? It won't lower mosquito populations, and affect other animals that rely on them for food.

              Very few animals, if any at all, rely so heavily on the handful of mosquito families that bite humans that those going extinct would harm them. There are thousands of mosquito species. Most animals that eat them eat dozens of different species. There's nothing special about a human blood filled mosquito to a critter which sustains itself off insect protein.

              Now in some areas the species that bite humans may be the dominant species, but that's because we're feeding them and creating places for them to breed. If they were gone there's a very good chance another species would fill that environmental niche, and it's unlikely that it would be one that feeds on humans.

            • I'm actually even more opposed to gene-drives for purposes other than driving a species to extinction.

              A gene drive is a "machine" built upon extremely powerful DNA-editing tools we stole from bacteria, which re-writes offspring DNA to ensure 100% heritability of both the gene drive and its payload - something impossible through normal natural selection.

              Once you release a gene drive into a population, it will almost certainly remain there until the species goes extinct. The only conceivable way to remove it

      There is a scientific definition for what constitutes a species. There are several factors involved in speciation [wikipedia.org] including reproductive isolation [wikipedia.org].

      Aedes aegypti [wikipedia.org] is non-native based upon the argument that it would without human interference remain isolated by geological boundaries such as oceans.

      There are a depressingly large number of examples of non-native species which have caused very real harm because either there are not enough predators of the new species or other species in the system don't have any defenses against the invader.
