US poised to release 2.4bn genetically modified male mosquitoes to battle deadly diseases

Genetically modified male mosquitoes may soon be buzzing across areas of California, in an experiment to stop the spread of invasive species in a warming climate.

The EPA earlier this month concluded that the test was safe to humans and the environment, but stipulated that the mosquitoes cannot be released near any potential tetracycline sources, an antibiotic that acts as an antidote. The regulations include within 500 meters of wastewater treatment facilities, commercial citrus, apple, pear, nectarine, peach growing areas, or commercial cattle, poultry and pig livestock producers. All the modified insects are equipped with a marker gene that scientists can use to tell them apart from wild ones and regular monitoring will be put in place to ensure the experiment is going to plan.

Still, the pilot has encountered some resistance. Citing concerns about possibly unforeseen consequences and a lack of transparency, critics are calling on California regulators to pull the plug.
