The FDA approved the trial back in August. But, local residents were opposed to the idea, causing the FKMCDBC to wait until Election Day to get a better picture of how the region felt.

"The referendum is not legally binding, so the agency [FKMCDBC] could still choose to go ahead with the trial when it next meets on November 19th," Technology Review writes. The company responsible for the modified mosquitoes, Oxitec, thinks that FKMCDBC will still go through with the trial and hopes to proceed as planned.

The FDA assessed that the mosquitos won't have a "significant impact" on the environment, and for its part, Oxitec is bullish on its effectiveness. "We expect to see the same results [from this trial] as we've seen everywhere else," CEO Hadyn Parry told Time. Tests in Brazil, the Cayman Islands and Panama have seen mosquito populations drop by over 90 percent.
