Experimental Breeding of Anopheles gambiae Giles in Papyrus Swamps

Abstract

IN Uganda, Anopheles gambiae Giles does not breed in the interior of papyrus swamps, in their natural, undisturbed state. But a considerable amount of breeding may occur at the periphery, outside the papyrus zone, particularly in hoof-prints, cattle-drinking places, and open natural pools¹. Also, where papyrus swamps have been drained and the land used for cultivating such crops as Colocasia, larvæ may be found in the shallow, sunlit pools between cultivation-mounds. On the whole, the swamps are not a potent source of malaria².
