Preliminary Inventory and General Aspect of the Distribution of Culicidae Species in the Steppe Region (M'sila, Algeria)

Mosquitoes are important living organisms that participate in the different levels of food chains. However, many families include vector species capable to transmit viruses, bacteria and parasites to both humans and animals, threatening the public health. The goal of this work was to describe the biological diversity of mosquito species in different areas in M'sila; Algeria based on the ecological nature of their habitat. The breeding sites found were 18 distributed in five areas (Berhoum, Bou Saâda, El hamel, Hammam Dhalaa and M'sila). The inventory that was carried out from September to April every year from 2017 to 2019 has revealed 14 species of Culicidae distributed through three genera. The Culiseta longiareolata species was the most predominant, occupying different types of permanent and temporary breeding sites. However, the distribution of species based on the ecological types of these sites revealed: Anopheles cinereus, Anopheles sergentii, Culex brumpti, Culex deserticola, Culex hortensis, Culex impudicus, Culex laticinctus, Culex martinii Culex modestus,Culex perexiguus,Culex pipiens, Culex theileri and Culiseta longiareolata species presence The study of mosquito populations in the M’sila region has never been approached ecologically, biologically and systematically. Focus of this study was devoted to the systematics of Culicidae species, as well as the characterization of their structure, using ecological parameters as well as the study of Spatio-temporal variations, of the Culicidae population.
