Firstly, the mosquito in question, Aedes aegypti is not native to the Americas. If we destroy them utterly, bats and whatever will go back to eating other mosquitoes.
Secondly, the release of genetically altered mosquitoes has been done before in the Cayman Islands, which reduced the mosquito population by 80%.
Thirdly, this type of modification (where the insects mate but the offspring don't develop) has been done in America before with the screw worm, which infected mostly livestock (and some humans). The screw worm has no redeeming qualities whatsoever, good riddance.
And finally, the headline "FDA Wants To Release Millions of Genetically Modified Mosquitoes In Florida" is one-sided and inflammatory. It does not mention "FDA wants to control several types of tropical fevers" or "FDA wants to eliminate a non-native pest that transmits disease".
Let's get everyone all worked up about the uncertainties of genetic engineering by completely ignoring the contextual reasons for doing so.
Because, you know, genetic engineering is bad in any form, even if it saves lives and brings the ecology closer to its original state.
Too bad you can't be modded +6. Replace those articles with your post and they would be far more effective at informing.
