Effect of swamp cultivation on distribution of anopheline larval habitats in Western Kenya.

摘要: Background & objectives: Malaria resurgence in highland regions of East Africa has been on increase. The spatio-temporal distribution larval habitats malaria vectors determines the adult vectors, hence, disease transmission. Vector’s ecology is necessary for strategic vector control through effective plan source reduction. Mapping targeted measures. purpose this study to assess and compare spatial seasonal variations anopheline Western Kenya. Methods: A comparative was conducted GPS geo-located relation lowland environments. Land use types were categorized all potential aquatic examined February, May, August November 2004. Data analyses performed using SAS JMP software. Results discussion: showed a higher percentage Anopheles gambiae s.s. (70.9%) than An. funestus (29.1%) highland. In lowland, s.l. comprised 60.1% while represented 39.9%. breeding confined valley bottom it dispersed lowland. type influenced occurrence positive due seasonality. We found high proportion sites cultivated swamps farmlands at site. These results suggest that swamp cultivation increases availability suitability thus transmission Kenya highlands environment.
