Abstract
THE tolerance to insecticides of normal and resistant strains of A. gambiae Giles has been measured by a number of workers1–3, but so far no figures for A. funestus, the second main malaria vector of Africa, seem to have been published. This communication records the results of tests carried out on this species in an area of Sokoto Province, Northern Nigeria, about ten miles west of the sprayed zones of the Western Sokoto Malaria Control Pilot Project. The test for susceptibility described by Busvine4 was applied to wild-caught females in the blood-fed and gravid states. Results are summarized in Table 1.
