A genetically modified mosquito has helped reduce the proliferation of mosquitoes spreading Zika and other dangerous viruses in Brazil, its developers said on Tuesday.
The self-limiting strain of the Aedes aegypti mosquito was developed by Oxitec, the UK-subsidiary of U.S. synthetic biology company Intrexon. The male mosquitoes are modified so their offspring will die before reaching adulthood and being able to reproduce.
Oxitec, which produces the mosquitoes in Campinas, announced it will build a second facility in nearby Piracicaba, Sao Paulo state, following strong results there in controlling the population of the Aedes vector that also carries the dengue virus.
