Friendly Aedes aegypti project

Oxitec and the City of Piracicaba began the “Friendly Aedes aegypti” project in April 2015. Oxitec’s OX513A self-limiting mosquitoes are being released in the CECAP/Eldorado neighbourhood of the city, covering an area of 5,000 residents. This district is the world’s first municipality to partner directly with Oxitec.

By the end of 2015, preliminary results already showed a reduction in wild mosquito larvae by 82%. On the basis of these positive results, the project has been expanded to cover an area of 60,000 residents in the centre of Piracicaba. This region was chosen due to the large flow of people commuting between it and surrounding neighbourhoods, so the project may benefit neighbouring areas of the city as well.

Oxitec is also building a new mosquito production facility in Piracicaba, which will have the capacity to produce 60 million mosquitoes a week to help protect over 300,000 people.

Oxitec’s solution received “commercial release” approval for releases throughout the country from the National Technical Commission of Biosafety (CTNBio) in 2014. In April 2016, the National Health Surveillance Agency of Brazil (Anvisa) announced that it would grant a special temporary registration for Oxitec’s mosquito.

Field trials

Previously, Oxitec’s OX513A mosquito has undergone extensive field trials in Brazil by independent collaborators, Moscamed and the University of São Paulo. Trials took place in the neighbourhoods of Itaberaba and Mandacaru in Juazeiro, and in Jacobina, and in all trials releases of Oxitec’s Aedes aegypti reduced the wild population by more than 90%.
