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. Earlier this month, the EPA cleared the UK-based biotech company Oxitec to release a maximum of roughly 2.4bn of its genetically modified mosquitoes through 2024, expand its existing trial in Florida and start a new pilot project in California’s Central Valley, where mosquito numbers are on the rise. Oxitec’s modified mosquitoes are male, and therefore don’t bite. They were developed with a special protein so that when they pair with a female mosquito the only viable offspring they produce are also non-biting males. The project specifically targets the Aedes aegypti mosquito, one of more than 3,500 mosquito species and a dangerous invasive insect that has spread diseases like dengue, Zika, Chikungunya, and yellow fever in other countries.
