Abstract: The involvement of Anopheles gambiae s.l. and Anopheles funestus in malaria transmission was investigated in Savannah area in Benin. This study shows the trends in malaria vectors dynamics and their part of contribution in malaria transmission.

Female mosquitoes were collected, using human landing catches. All the anopheline mosquitoes were assessed for species identify and sporozoite infection status.

Most of the anopheline mosquitoes collected were members of the An. gambiae complex (80.90%) and An. funestus group (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 vector as far as abundance is concerned, sporozoite prevalence was three times higher with An. funestus than An. gambiae.

This study provides useful informations on the relative contribution of malaria vectors to the perennial malaria transmission in the study area.
