Bed nets treated with insecticide aren’t enough to stop a new “super mosquito”—the result of interbreeding by two malaria mosquito species in the West African country of Mali.
Anopheles gambiae, a major malaria vector, is interbreeding with isolated pockets of another malaria mosquito, A. coluzzii. Entomologists initially considered them as the “M and S forms” of Anopheles gambiae—but now recognize them as separate species.
