A study to assess mosquito species occurrences and the effects of some ecological characteristics on their breeding was undertaken in Mizoram during 2010-2013.Atotal of 8328mosquitoes, representing the 5 genera of: Anopheles, Aedes, Culiseta, Culex and Toxorhynchites were collected altogether of 20 species. They were found in a wide variety of habitats with the altitudinal variation of 54 - 1150m. The zones of lower elevation shared higher species abundance than the higher elevation. The most dominant genus was Aopheles followed by Culex, Culiseta, Aedes and Toxorhynchites. The results of forward multiple regression analyzed the effect of environmental parameters on the relative abundance of immature stages ofmosquitoes. These included dissolved oxygen, TDS, temperature, alkalinity, pH and hardness.
