The FDA has completed the environmental review for a proposed field trial to determine whether the release of Oxitec Ltd.'s genetically engineered (GE) mosquitoes (OX513A) will suppress the local Aedes aegypti mosquito population in the release area at Key Haven, Florida. After considering thousands of public comments, the FDA has published a final environmental assessment (EA) and finding of no significant impact (FONSI) that agrees with the EA's conclusion that the proposed field trial will not have significant impacts on the environment.
[The genetically engineered mosquitoes possess a] self-limiting gene that prevents the offspring from surviving. Male modified mosquitoes, which do not bite or spread disease, are released to mate with the pest females. Their offspring inherit the self-limiting gene and die before reaching adulthood—before they can reproduce or spread disease.
[Release of the OX513A mosquitoes in both Brazil and the Cayman Islands] strongly suppressed the target wild population—by 80–95%

That's the best case scenario. As you said, these mosquitoes are an invasive species. They may have altered the food chain enough that it can never return to the previous state of balance and removing these mosquitoes will cause it to careen even further out of whack. Also there is good evidence that other species carry zika too, they just aren't quite as virulent because this species bites frequently and "sips" while the others bite less often and take deep drinks.
