In order to better understand the systematic and the biodiversity of mosquitoes in Tébessa (north-eastern Algeria), we proceeded to harvest Culicidae larvae using the "dipping" method in five different biotopes, 3 urban and 2 rural with diffèrent characteristics, these biotopes were located in 5 stations. This study was conducted over a nine-month period extending from September 2014 to May 2015. Nine species of Culicidae are identified belonging to two subfamily Anophelinae and Culicinae and to four genera (Culex, Culiseta, Aedes and Anopheles), Culex (Culex) pipiens Linné 1758 was the most dominant species by their abundance and frequency (64%, 42,58%) followed by Culiseta (Allotheobaldia) longiareolata Macquart 1838 whose relative abundance was 18,6% and the occurrence frequency was 21,43%. The culicidian population found was moderately diverse and moderately balanced (H’= 1, 53 bits, H’max=3, 17 bits, E=0, 48). Results also found that Culiseta longiareolata was the most appeared species in the Sidi Yahia location, and the species of Culex pipiens, Culex theileri and Culiseta longiareolata were found in association with all inventoried species.
