Estimation of the survival rates of field populations of malaria vectors in Kenya

Abstract

Results revealed that the average survival rates between the dry and the wet seasons mosquito populations of individual species was possible in An gambiae s. str. The survival for this species was higher during the dry than the wet season. Overall, the highest survival rate was of the short rains population of An. merus, while An. gambiae s.l. had the lowest. An. arabiensis had the second lowest survival rate. By expressing the vectorial capacity of each population as a ratio of the lowest calculated, the short rains An. merus had the highest capacity, followed in, descending order, by dry season An. gambiae s. str., long rains. An. gambiae s. str., An. gambiae s.l., and lastly, An. arabiensis. The most hardy and long surviving mosquito disease vector is more dangerous than that which has a short lifespan
