Mosquito density is of great importance for preventing mosquito?borne diseases. Meteorological factors that influence the density of mosquitoes include temperature, rainfall, and humidity. This article reviews the progress in the impacts of climate change on mosquito populations, the relationship between meteorological factors and mosquito density, and the establishment of mosquito density predictive models using meteorological factors. Most current studies consider the association between single meteorological factors and mosquito density over the same period. But also some studies discuss the relationship between the time series of meteorological factors and mosquito density data. Moreover, there are some studies that consider the effects of meteorological factors and other factors affecting the density of mosquitoes. The present paper briefly describes the current problems and future directions in this research field.
