Anopheles gambiae complex

Abstract

THE existence of two fresh-water forms (A and B) of Anopheles gambiae Giles which, when crossed, produce sterile F1 males has been established by Davidson and Jackson1. A salt-water tolerant strain of the same species from near Tanga, Tanganyika, has been shown to be partially incompatible with two strains of the group A fresh-water form2,3, while the variety melas has been shown to be incompatible with a fresh-water form (group unknown) from a nearby area in Liberia4. © 1962 Nature Publishing Group.
