Default Malaria Vector Springs a Surprise

Previously unknown subgroup of Anopheles gambiae that rests outdoors instead of indoors raises questions for malaria management in Africa.

"Researchers have discovered a subspecies of malaria-carrying mosquito that lives outside, rather than in human homes as previously known types do. The finding, reported today in Science1, points to a potential gap in methods of malaria control."
"The newly discovered mosquito group — a subtype of A. gambiae dubbed Goundry after a village in Burkina Faso, western Africa, where it was found — could be one reason why eradication attempts have not been entirely successful. Unlike other A. gambiae, adult Goundry mosquitoes spend their time outside, thus avoiding indoor sprays. Furthermore, when fed blood carrying Plasmodium falciparum, the group acquired the parasite more easily than did its relatives."
