2nd Gen Friendly™ Mosquitoes Successfully DeployedJune 20, 2019
Oxitec Ltd. has announced the successful completion of the first field trial in Brazil of its 2nd Generation Friendly™ Aedes aegypti technology. The pilot project was conducted in the city of Indaiatuba, and showed the new strain's effectiveness in suppressing populations of A. aegypti, the primary vector of Dengue, Zika, Chikungunya, and Yellow Fever.
Friendly™ Aedes aegypti mosquitoes were released in four separate communities approved by CTNBio, Brazil's national biosafety authority during a year-long trial that started in May 2018. The trial was set to test the performance of 2nd Generation Friendly™ Aedes aegypti technology. The numbers of wild A. aegypti were kept at low levels during the high season in all treated neighborhoods, while the populations in untreated areas rose as normal.
An average 89% peak suppression was recorded in two communities treated with a low release of mosquitoes, and an average of 98% across two communities treated with a higher release rate. An optimal suppression rate of 96% was observed in one community with a high release rate over a four-week period was achieved.
Dr. Graziela Garcia, the City of Indaiatuba's secretary of health said that the "collaboration between the city and Oxitec has been positive and transparent, and the suppression results in the areas that received Oxitec mosquitoes were excellent."
