26 September 2019 / Oxitec is casting doubt on a recently published scientific paper reporting the uncontrolled spread of genetically engineered mosquitoes in Brazil. The company is saying that only about five percent of the insects would have survived, and there are no indications that they would spread in future. In addition, they say there is no evidence to show that the transgenes have actually spread with the mosquitoes which survived the trials. However, the claims made by Oxitec are scientifically unconvincing.
