How was Wolbachia introduced into Aedes aegypti?
Aedes aegypti does not naturally carry Wolbachia. To introduce Wolbachia into Aedes aegypti, researchers had to inject it into Aedes aegypti eggs, eventually producing adult Aedes aegypti that carried the bacterium. As Wolbachia is maternally transmitted, the females then passed the bacterium to their offspring. Read on to see photos of this process.
