Can someone with knowledge of this particular experiment explain how they've overcome the regulations that have stopped Oxitec / Intrexon with their aedes aegypti solution? They key regulatory factors cited against Oxitec, especially in their Florida Keys trials in the past year, were centered around controlling for the release of only males (which do not bite humans), thus avoiding transmission of any kind from the genetically modified varieties, or bacterially modified varieties in this case.

Oxitec has worked for years to filter their mosquitoes so only ~0.2% of the released mosquitoes are female[1]. They then had to demonstrate that and more in many trials before being allowed to release their mosquitoes in the wild in Panama and Florida.

Otherwise, it's great that Google can overstep the other factors that would stop this solution like NIMBYism and working with county / municipal boards. These solutions are great.

It's mostly because circuitous jurisdictional turf battles. The bacterial approach involves applying something to the mosquitos to kill them, rather than modifying the mosquitos, so it apparently counts as a pesticide, which puts it under EPA purview. Producing genetically modified animals is subject to FDA review instead. Apparently the EPA has a lighter touch, as the Wolbachia mosquitoes got approved by the EPA for use in the same area that was originally going to be the site of an Oxitec test in the Keys that got squashed by the FDA.

Interesting article. It's also loaded with a lot of "we're not sure", "we'll have to watch that closely", and "we don't believe it's a problem".
