Concerns have been raised scientists could be to blame for the Zika virus outbreak after genetically modified insects were released into Brazil three years ago.

Didcot-based biotechnology company Oxitec worked on the same type of mosquito that carries the virus in 2012, engineering them to have offspring that die out before they can breed, reducing the population of disease-carrying bugs.

Some scientists questioned the wisdom of the plan at the time and it has led to critics claiming the modification could have sparked the current outbreak.

The Aedes mosquito, pictured, was genetically modified by British firm Oxitec in 2012 and released into Brazil to mate with disease carrying bugs and produce offspring that would quickly die off, reducing the numbers

But Oxitec refuted these claims and has actually been asked to expand its work in Brazil to help tackle the outbreak, opening a new mosquito facility in Piracicaba.

Chief executive Hadyn Parry labelled the claims as ‘simply untrue’.

He added: ‘All vector control solutions – insecticides, traps, and ‘sterile’ mosquitoes get deployed in areas with a high incidence of disease to help stop the spread of the disease at its source.
