The U.S. Food and Drug Administration said on Friday that a field trial testing Intrexon Corp's genetically engineered mosquitoes, meant to be used in the battle against Zika, would not have a significant impact on the environment. The company wants to conduct a trial in the Florida Keys to assess the effectiveness of the genetically modified mosquitoes in reducing populations of Aedes mosquitoes, which can spread diseases including Zika, dengue, yellow fever and chikungunya. Florida began aerial spraying on Thursday to kill mosquitoes in a Miami neighborhood with the first U.S. spread of the Zika virus.
