abstract
The aim of this study was to carry out an inventory of Culicidae species and the associated fauna of crustaceans harvested in the Echatt region of north eastern Algeria for a period extending from January 2014 to December 2014. The systematic study of Culicidae was carried out using the keys of [1,2] reveals the presence of 11 species: five belonging to the genus (Culex pipiens, Culex hortensis, Culex univittatus, Culex brumpti and Culex modestus). Three species belonging to the genus Culiseta (Culiseta subochrea, Culiseta annulata and Culiseta moristans), two in the genus Aedes (Aedes pullatus and Aedes vexans) and one species in the genus Anopheles (Anopheles coustani). In order to characterize the Culicidal stand in our study area, ecological indices were calculated to determine abundance, the richness, the centesimal frequency and the distribution of abundance of the different species composing this stand.
