In this study, we reported a longitudinal decline in the density of malaria mosquito vectors in rural communities in Tanzania during the period 1998-2009. Part of the decline could be associated with changes in the pattern of monthly rainfall. A similar decline in malaria vector densities could contribute to the decrease in levels of malaria infection reported from many parts of Sub-Saharan Africa.
