" An experimental trial to reduce the mosquito population in Brazil through the deliberate release of 450,000 genetically modified mosquitoes has failed miserably and may have even created a genetic hybrid super species.
British biotech company Oxitec conducted a 27-month long experiment in 2013 Jacobina, Brazil, aimed at reducing the local mosquito population by 90 percent while preserving the genetic integrity of the local insect population.
The overall goal was to curb the spread of mosquito-borne diseases, such as yellow fever, dengue, chikungunya, and Zika, by releasing half a million OX513A mosquitoes. The insects are a genetically-modified version of the Aedes aegypti mosquito, which combined a breed from Mexico with a breed from Cuba.
However, an Oxitec spokesperson claims the research contains “numerous false, speculative and unsubstantiated claims and statements about Oxitec’s mosquito technology” claiming instead, in a three-page document, that the paper did not identify any “negative, deleterious or unanticipated effect to people or the environment from the release of OX513A mosquitoes.”
Oxitec also disputes the claim about “mating discrimination” saying it has never occurred in any release of an estimated total of one billion Oxitec male mosquitoes released worldwide."
