The effects of anthropogenic climate change are now impacting terrestrial ecosystems, and are playing a crucial role in changes to insect populations: on biology and diversity, on geographic distribution, on geographical range, number of generations, and on abundance levels. The precise consequences are still unknown, but the effects of climate change on insects have now been recognized from the level of individual species to communities, most notably in the form of temperature-related range shifts. No thorough explanation has been offered for how this will influence the spread of vector- borne diseases attributable to climate change. With regard to breeding requirements, there is evidence of adaptation of some mosquito species to fragmented-forest environments in Thailand, while Anopheles dirus larvae are now unreported in the rock pools of some bamboo forests and caves. Studies on a larger geographical scale may provide more insight into the adaptive selection of these alternative habitats by mosquito vectors. Regarding our own field observations on the bionomics of mosquito vectors, some generalizations can already be made about trends in Thailand. This manuscript discusses the subject of climate change and its potential impacts on these mosquito vectors, especially.
