Estimation of the Survival-Rate of Anopheline Mosquitoes in Nature


THE daily survival-rates of Anopheles gambiae and A. funestus in two areas of tropical Africa have recently been estimated from the ratio of their sporozoite-rates immediately on capture and those recorded after keeping wild-caught specimens alive for the duration of the extrinsic cycle of the predominant malaria parasite1,2. This method naturally involves considerable time for the dissection and keeping alive of significant numbers of mosquitoes.
