Characterization of mosquito breeding sites in the Cape Verde islands with emphasis on major vectors

Abstract

Characterization of breeding site environment is a crucial step into the understanding of mosquito biology and the dynamics of the transmitted diseases. In Cape Verde a single study addressed this issue, however more than 30 years has passed making it obsolete. In the present study we characterized mosquito breeding sites with emphasis on two major vectors. During mosquito sampling, measurements of physicochemical parameters of standing water were conducted. Aquatic fauna and flora were also characterized. We found a high species richness in the study area. Mosquitoes reproduction was dependent of standing water created by human activities. We did not detect differences between water collections used by mosquitoes to breed when compared to those unused. Our results suggest that mosquito biological control, by the use of freshwater fish, is somewhat effective. Moreover, our results highlight the breeding site management as an important vector control strategy in irrigated areas in Cape Verde.
