isolation and genetic characterization of rift valley fever virus from aedes vexans arabiensis, kingdom of saudi arabia.an outbreak of rift valley fever in the kingdom of saudi arabia and yemen in 2000 was the first recognized occurrence of the illness outside of africa and madagascar. an assessment of potential mosquito vectors in the region yielded an isolate from aedes vexans arabiensis, most closely related to strains from madagascar (1991) and kenya (1997).200212498669
rainfall patterns and population dynamics of aedes (aedimorphus) vexans arabiensis, patton 1905 (diptera: culicidae), a potential vector of rift valley fever virus in senegal.the importance of rainfall for the development of aedes vexans arabiensis populations, one of the potential vectors of rift valley fever in west africa, was demonstrated in a two-year follow-up study conducted in the ferlo region of senegal. in 2003, the rainy season began with heavy rains and, as a result, temporary ponds, the breeding places for mosquitoes, were flooded at their maximum level immediately. in such conditions, aedes vexans arabiensis populations are abundant at the very beginnin ...200516007962
the status of rift valley fever in animals in saudi arabia: a mini review.in august-september 2000, an overwhelming outbreak of rift valley fever (rvf) struck the southwestern part of saudi arabia and adjoining yemeni territories. during the outbreak, which was the first ever to be recorded outside africa, around 40,000 animals, mostly sheep and goats, died or aborted and 883 cases, with 124 deaths, were recorded among humans in saudi arabia. an additional 1328 human cases, with 166 deaths, were concurrently recorded in northwestern yemen. vector studies in saudi arab ...201121923257
rainfall triggered dynamics of aedes mosquito aggressiveness.inspired by davidson method of estimating daily survivals of a structureless population of mosquitoes, we present a model which describes the behavior of floodwater mosquitoes in terms of emergence functions following a rainfall event, blood feeding frequency and parous stages, and survival at various stages. as a generalization of the davidson formula, we have developed an approach for dealing with the dynamics of structured population of mosquitoes, and derived various formulas allowing assess ...200616876201
the mosquito aedes (aedimorphus) vexans arabiensis as a probable vector bridging the west nile virus between birds and horses in barkedji (ferlo, senegal).active catches of adult females of aedes vexans arabiensis patton, (diptera: culicidae) patton by nets or aspirator, were conducted in 2003 and 2004 in the vegetation at the edge of temporary ponds in barkedji, senegalese ferlo area. two hundred and forty-one engorged females were captured, dissected and the gut content adsorbed on a whatman filter paper and analysed using the enzyme-linked immunosorbent assay (elisa) technique to determinate the bloodmeal origin. results indicated that ae v. ar ...201121790686
