“ Will Brazilian antigambiae measures succeed in Africa? As time goes by it will almost certainly be found that an increasing number of areas can be cleaned of gambiae and be freed of gambiae-transmitted malaria. In Africa, where the species is already widely disseminated, it would seem logical to attempt eradication by beginning in the center of the area to be cleaned and working always outward. It has been demonstrated in Brazil that species eradication of Aedes aegypti and Anopheles gambiae is feasible. ”
