Mosquitoes are considered as vectors of serious human diseases. The prevention of parasitic and arboviral vector-borne diseases is based mostly on vector control strategies. This control cannot be effective unless a strong knowledge of mosquito biology and distribution in the working area. In this context, and in order to improve the knowledge on the specific diversity of the culicids fauna in the region of Khenchela (northeast of Algeria), an inventory of mosquitoes was carried out for the first time in this region. Larval collection was conducted in various types of habitats through continuous monitoring of seven sites from May 2020 to September 2021.Systematic study revealed the presence of 10 species belonging to 5 genera; including Culexpipiens (Linneaus, 1758), Culexterritans (Walker, 1856), Culextheileri (Theobald, 1903), Culexmodestus (Ficalbi, 1890), Culisetalongiareolata (Macquart, 1838), Culisetaannulata (Schrank, 1776), Aedesgeniculatus (Olivier, 1791), Aedesvexans (Meigen, 1830), Orthopodomyiapulcripalpis (Rondani, 1872) and Uranotaeniaunguiculata (Edwards, 1913). The species Cx. pipiens was the most abundant (44.26 %) followed by Cs. longiareolata (39.57 %). The variation of diversity in the different sites depends on the type of breeding habitat. Our findings provide very important information on biodiversity, distribution and the relationship between species abundance and ecological factors. Therefore, the results can be very useful for the design and implementation of effective control programs.
