Last month, the US Environmental Protection Agency approved the release of genetically modified mosquitoes. Under a 2-year Experimental Use Permit, a company called Oxitec has been granted permission to release over 1 billion genetically modified mosquitoes across 6,600 acres in Florida and Texas.

Oxitec hopes to demonstrate through field trials that their latest GM mosquito strain can reduce local populations of Aedes aegypti — the mosquito species that transmits dengue fever, yellow fever, chikungunya, and the Zika virus.
