Genetically modified mosquitoes to combat Zika?

Genetically modified mosquitoes could be released in the Florida Keys as early as this spring, an official said, after voters in Monroe County, Florida, approved the experiment. This could be the first time a genetically modified animal is released into the wild in the United States.

The male mosquitoes modified by Oxitec are designed to control Aedes aegypti mosquito populations by mating with wild females, and passing a gene to their offspring that stops them from reaching maturity. Only male mosquitoes are to be released (one out of every 1,000 could be female). Male mosquitoes do not bite.

The mosquitoes are meant to undermine the same mosquitoes that spread Zika.
