PAT (Projeto Aedes Transgênico) agreed upon to test, in urban areas, the social, technical and operational aspects of a genetic control program releasing transgenic male mosquitoes of Aedesaegypti in the field. Here we show the social aspects, regarding the regulatory issues, action plan and strategies used before and during the mosquito release. This work also evaluated people’s perception when the studies were finished and releases stopped. The evaluation considering the areas used in this study showed that different population levels (local, regional, national and international) did not presented negative opinion about the actions taken place in Brazil. It was also possible to evaluate people’s perception regarding their positivity about the project and the activities (monitoring, mosquito release and others) carried out.
