Another powerful part of this system: We can test mosquito behavior under naturalistic conditions. Anopheles gambiae, the African malaria mosquito, likes to hunt at night when humans are sleeping. Why is the role of human scent so important in understanding malaria transmission? Understanding what chemicals in human scent drive differential attraction to certain humans is important, because if we can identify these chemicals, we can help to inform personal bite risk. How can these findings translate into mosquito interventions in the U.S. and around the world?
