An important variable when explaining the variability in transmission is the breeding behaviour of the different vector species and the availability of breeding sites. The aim of this study was to determine the geographical variability of certain entomological parameters: human biting rate (HBR), sporozoitic index (SI) for <jats:italic>Plasmodium falciparum<\/jats:italic> and entomological inoculation rate (EIR).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>The study was carried out in a small village in the mainland region of Equatorial Guinea. Adult mosquitoes were collected by CDC light traps. Polymerase Chain Reaction was employed to identify the species within the <jats:italic>Anopheles gambiae<\/jats:italic> complex and to detect <jats:italic>P. falciparum<\/jats:italic> sporozoites. The geographical position of all the dwellings in the village were taken using a global positioning system receiver unit. Data relating to the dwelling, occupants, use of bednets and the mosquitoes collection data were used to generate a geographical information system (GIS). This GIS allowed the minimum distance of the dwellings to the closest water point (potential breeding sites) to be determined.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>A total of 1,173 anophelines were caught: 279 <jats:italic>A. gambiae s.l.<\/jats:italic> (217 <jats:italic>A. gambiae s.s.<\/jats:italic> and one <jats:italic>Anopheles melas<\/jats:italic>), 777 <jats:italic>Anopheles moucheti<\/jats:italic> and 117 <jats:italic>Anopheles carnevalei<\/jats:italic>. <jats:italic>A. moucheti<\/jats:italic> proved to be the main vector species and was responsible for 52.38 [95% IC: 33.7\u201371] night infective bites during this period. The highest SI was found in <jats:italic>A. carnevalei<\/jats:italic> (24%), even though the HBR was the lowest for this species. A significant association was found between the distance from the dwellings to the closest water point (River Ntem or secondary streams) and the total HBR.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>A clear association has been observed between the distance to potential breeding sites and the variability in the anopheline density, while the other parameters measured do not seem to condition this spatial variability.
