Abstract

The incidence of malaria has recently increased in many parts of the tropics. This increase is due mainly to drug resistance and the failure of disease control measures. But changes in vector (mosquito) and host (human) ecology may also play a role. This chapter presents results from field studies in Belize showing that freshwater community changes lead to changes in malaria transmission. Changes in vegetation structure, mediated by an anthropogenic increase in aquatic nutrients, lead to replacement of one mosquito species by another. Species-specific habitat selection by mosquito females leads to the replacement of a less efficient malaria vector by a more efficient one. Vector ecology is influenced by changes in land cover and host availability, leading to predictable changes in malarial dynamics.
