First-ever US release of genetically modified mosquitoes begins in Florida Keys

(CNN)The first release of genetically modified mosquitoes in the United States began this week in the Florida Keys -- the culmination of a decade-long effort by local mosquito control authorities to see if a genetically modified organism is a viable alternative to spraying insecticides in the region.

Water is added to a box of genetically modified mosquito eggs in the Florida Keys.
For the first 12-week phase, blue-and-white boxes containing about 12,000 GMO eggs developed by a US-owned, British-based company called Oxitec have been placed in six small areas of Ramrod Key, Cudjoe Key and Vaca Key. When water is added, the mosquitoes hatch, mature and enter the environment over the next week or so.
    A small, vocal group of Florida Key residents have fought the release of what they call "mutant mosquitoes" since the project was announced -- and they are incensed.
      "Our opposition has been long and strong," said Barry Wray, the executive director of the Florida Keys Environmental Coalition. "We live here, this our home, and they're forcing this down people's throats."
      "The only thing you can do legally at this point is stand in your yard with an insect fogger," said Mara Daly, a resident of Key Largo, Florida, who has fought the release for eight years. "You can't touch a box, but you can fog the s**t out of your own yard if you don't want to be a part of the trial."
      Local residents in the Florida Keys continue to protest the release of "mutant" mosquitoes.

      First release of GMO mosquito in US

      The Florida Keys project, greenlit by the US Environment Protection Agency in May 2020, was approved to release up to 750 million genetically altered mosquitoes in 2021 and 2022.
      The program's target: Aedes aegypti, an invasive species of mosquito that carries several potentially deadly diseases, including yellow fever, dengue and Zika virus.
      The rapid spread of Zika became a worldwide public health emergency in 2016 after an alarming spike of babies born with abnormally small heads -- a condition called microcephaly -- to mothers infected with Zika in Brazil and French Polynesia. Aedes aegypti soon spread the virus to at least 34 countries and territories, including Texas and Florida in the US.
      Dengue outbreaks, often epidemic in Puerto Rico, the Caribbean, Latin America and Southeast Asia, also strike south Florida: Key Largo had a small outbreak in 2019 and 2020, while Key West had outbreaks in 2009 and 2010.
      Known as "break-back fever" due to the piercing headaches and joint pain it creates, dengue also causes flu-like symptoms, including fever and rashes. Serious cases can cause bleeding, shock, organ failure and even death.
      In reality, the 2021 release will include far fewer than the 750 million approved by the EPA, said Nathan Rose
