Abstract: In this paper, the niche theory was used to analyse the interspecific competition between two dominant mosquitoes Culex pipiens pollens and Armigeres subalbatus at certain area of Meng Mountain.It includes niche breadth, proportional similarity, niche overlap and niche separation.The phenomenon of the two moequitoes competition in the same habitat was analysed in the qualitatitve and quantitative niche.The two dimensional niches in time and temperature resource were comparatively.analysed also.The results showed that the two mosquitoes had more proportion similarity, so the competition was certainly, and Armigeres subalbatus would win the competition because it had more niche breadth and more niche overlap to Culex pipiens pollens.The two mosquitoes would temporarily coexist by the way of niche separation in the time and temperature resource.
