Google’s Alphabet is seeking U.S. government approval to release millions of mosquitoes in California and Florida as part of its “Debug” research program, which aims to reduce diseases spread by mosquito species. Multiple outlets report that the company is requesting permits covering releases over about the next two years. Figures cited vary by outlet, with some describing plans for 32 million sterile mosquitoes and others referencing up to 64 million, reflecting differences in how total deployments are characterized or updated.
The program is described as using non-biting male mosquitoes and/or mosquitoes treated to limit reproduction or alter disease transmission. According to reporting, the approach involves releasing mosquitoes that are not intended to bite and that are being modified so they cannot reproduce effectively, or are infected with the bacterium Wolbachia pipientis to suppress disease transmission. Scientists and public-interest commentary in the coverage discuss potential effects on mosquito populations and mention that an earlier trial in Fresno reported a large reduction in the number of biting female mosquitoes of a target species.
Coverage also reflects public and scientific debate about interfering with ecosystems, balanced against discussion of potential health benefits such as reducing risk from diseases including dengue and other mosquito-borne illnesses.
