Background:Management of arboviruses relies heavily on vector control. Implementation and sustenance of effective control measures requires regular surveillance of mosquito occurrences, species abundance and distribution. The current study evaluated larval habitat diversity and productivity, mosquito species diversity and distribution in selected sites along the coast of Kenya.Methods:A cross-sectional survey of mosquito breeding habitats, species diversity and distribution was conducted in urban, peri-urban and forested ecological zones in Mombasa and Kilifi counties.Results:A total of 13,009 immature mosquitoes were collected from 17 diverse aquatic habitats along the coast of Kenya. Larval productivity differed significantly (F(16, 243)= 3.21, P < 0.0001) among the aquatic habitats, with tyre habitats recording the highest larval population.Culex pipiens(50.17%) andAedes aegypti(38.73%) were the dominant mosquito species in urban areas, whileAe. vittatus(89%) was the dominant species in forested areas. In total, 4,735 adult mosquitoes belonging to 19 species were collected in Haller Park, Bamburi, Gede and Arabuko Sokoke forest. Urban areas supported higher densities ofAe. aegypticompared to peri-urban and forest areas, which, on the other hand, supported greater mosquito species diversity.Conclusions:HighAe. aegyptiproduction in urban and peri-urban areas present a greater risk of arbovirus outbreaks. Targeting productive habitats ofAedes aegypti, such as discarded tyres, containers and poorly maintained drainage systems in urban areas and preventing human-vector contact in peri-urban and forested areas could have a significant impact on the prevalence of arboviruses along the coast of Kenya, forestalling the periodic outbreaks experienced in the region.
