(56.86%), {A}n. funestus s.l. (32.57%), {A}n. hancocki (9.38%), and {A}n. nili (1.18%). {A}pplying {PCR} revealed that specimens of the {A}n. funestus group were {A}n. funestus s.s. and {A}n. gambiae complex were mostly {A}n. melas and {A}n. gambiae s.s. of the {M} and {S} molecular forms with the {M} forms being the most predominant. {T}he natural distribution patterns of {A}nopheles species were largely determined by altitude with some species having unique environmental tolerance limits. {A} human blood index ({HBI}) of 99.05% was recorded. {M}ean probability of daily survival of the malaria vectors was 0.92, with annual mean life expectancy of 21.9 days and the expectation of infective life was long with a mean of 7.4 days. {T}he high survival rates suggest a high vector potential for the species. {T}his information enhances the development of a more focused and informed vector control intervention.}, keywords = {{PALUDISME} ; {TRANSMISSION} ; {VECTEUR} ; {INSECTE} ; {REPARTITION} {GEOGRAPHIQUE} ; {FACTEUR} {CLIMATIQUE} ; {ALTITUDE} ; {PLUIE} ; {TEMPERATURE} ; {COUVERT} {VEGETAL} ; {PLANTATION} ; {DIVERSITE} {SPECIFIQUE} ; {ABONDANCE} ; {CHANGEMENT} {CLIMATIQUE} ; {CAMEROUN}}, booktitle = {}, journal = {{T}ransactions of the {R}oyal {S}ociety of {T}ropical {M}edecine and {H}ygiene}, volume = {104}, numero = {}, pages = {453--460}, ISSN = {0035-9203}, year = {2010}, DOI = {10.1016/j.trstmh.2010.02.006}, URL = {https://www.documentation.ird.fr/hor/fdi:010050145}, }
