Recommendation

Despite strong pushback from Florida residents and a decade of regulatory scrutiny, British biotech firm Oxitec was allowed to release millions of genetically engineered mosquitos into the Florida Keys. Some locals don’t trust the company’s motives and technology, while others worry about its effects on the region’s ecosystem. Researchers hope the experiment will kill off a species of mosquitos responsible for deadly diseases in humans.

Take-Aways

  • Oxitec, a UK biotechnology company, is releasing genetically engineered “killer” mosquitoes into the Florida Keys.
  • Oxitec’s experiment involves releasing non-biting male mosquitos, which are bioengineered with a gene that kills larval female offspring.
  • Some Keys residents worry that the genetically-altered insects will harm Florida’s ecosystem.
