Bionomics of @entity313 Giles, An. arabiensis Patton, An. funestus Giles and An. nili (Theobald) (Diptera: Culicidae) and transmission of XXXX in a Sudano-Guinean zone (Ngari, Senegal).

An entomological study was conducted in a village of Sudano-Guinean savanna in Senegal, during the rainy season from July to November 2001, to investigate the biology and the involvement of each anopheline species in @entity311 transmission. Mosquitoes were captured when landing on @entity1 volunteers and by pyrethrum spray catches. Twelve anopheline species were captured. Four species amounted to 97% of @entity1 -bait sampling: @entity313 molecular form S, An. arabiensis, An. funestus, and An. nili s.s. All An. gambiae and An. nili females were fed on @entity1 , whereas the anthropophilic rate was 94.5% for An. funestus and 88.9% for An. arabiensis. @entity3964 was the only @entity311 parasite found, and infecting only An. gambiae, An. arabiensis, An. funestus, and An. nili. The circumsporozoite rate was 4.5% for An. gambiae, 1.6% for An. arabiensis, 3.9% for An. funestus, and 2.1% for An. nili. During the period of study, the entomological inoculation rate was estimated to 264 infected bites. An. gambiae, An. arabiensis, An. funestus, and An. nili were responsible respectively of 56, 3, 20, and 21% of @entity311 transmission. This study shows for the first time the implication of An. nili in @entity311 transmission in this area and the complexity of the @entity311 vectorial system that should be taken into account for any @entity311 control strategy.
