The spread of malaria in savannah area in Benin: The contribution of Anopheles gambiae and Anopheles funestus in the transmission

摘要

The role of the Anopheles complex and Anopheles funestus Giles in the malaria transmission wasinvestigated in a Savannah area in Benin. This study shows the part of their contribution in malariatransmission in the study area. Mosquitoes were collected, using human landing catches. All theanopheline mosquitoes were assessed for species identify and sporozoite infection status. Most of theanopheline mosquitoes collected were members of the An. gambiae complex (80.90%) and An. funestusgroup (14.36%). An. gambiae and An. coluzzii were found in sympatry. All of the females of the An.funestus group investigated were identified as An. funestus s.s. In spite of being the major malaria vectoras far as abundance is concerned, sporozoite prevalence was three times higher with An. funestus thanAn. gambiae. This study documented useful informations on the relative contribution of malaria vectorsto the perennial malaria transmission in the study area.
