temporal distribution and spatial pattern of abundance of the rift valley fever and west nile fever vectors in barkedji, senegal.the temporal distribution and spatial pattern of abundance of mosquito vectors of rift valley fever (rvf) and west nile fever (wnf) were studied during the 2005 and 2006 rainy seasons at barkedji, senegal. mosquitoes were collected every two weeks with cdc light traps with dry ice at 79 sites including temporary ponds, barren, shrubby savannah, wooded savannah, steppes, and villages at different distances (between 0 and 600 m) from the nearest pond. the temporal distributions of these vectors va ...201122129415
vector competence of culex neavei and culex quinquefasciatus (diptera: culicidae) from senegal for lineages 1, 2, koutango and a putative new lineage of west nile virus.west nile virus (wn virus) is one of the most widespread arbovirus and exhibits a great genetic diversity with 8 lineages, at least 4 (1, 2, koutango, and putative new) are present in africa. in west africa, culex neavei and culex quinquefasciatus are considered as potential vectors for wn virus transmission in sylvatic or urban context. we analyzed the vector competence of these culex species from senegal for african lineages and envelope proteins sequences of viral strains used. we showed that ...201424567319
west nile virus transmission in sentinel chickens and potential mosquito vectors, senegal river delta, 2008-2009.west nile virus (wnv) is an arthropod-borne flavivirus usually transmitted to wild birds by culex mosquitoes. humans and horses are susceptible to wnv but are dead-end hosts. wnv is endemic in senegal, particularly in the senegal river delta. to assess transmission patterns and potential vectors, entomological and sentinel serological was done in ross bethio along the river senegal. three sentinel henhouses (also used as chicken-baited traps) were set at 100 m, 800 m, and 1,300 m from the river, ...201324084679
