From April to October 2014, the Gorgas Institute conducted a project to suppress local Aedes aegypti using Oxitec’s self-limiting mosquito. The project took place in Nuevo Chorrillo, a residential suburb of the Arraiján District, west of Panama City. This 10 hectare urban area is home to approximately 900 residents.

Within six months, the population of wild Aedes aegypti was suppressed by 93%. Suppression in the treatment area was maintained as the wet season progressed – the time of year in which mosquito numbers typically rise significantly.

Prior to the study, approval was obtained from Panama’s National Biosafety Committee, and from the Ministries of Agricultural Development and Commerce and Industry. In addition, extensive community engagement was carried out locally.
