Inventory and Distribution of Mosquitoes (Diptera, Culicidae) in the Aures Region (Batna, Algeria)

Abstract

Mosquitoes are the most terrifying both for their abundance and for the diseases they transmit. They are vectors of malaria, lymphatic filariasis and arbovirus such as yellow fever, dengue, viral encephalitis and African horse sickness. These characteristics give this fauna prominent importance and health interest. To identify the most widespread mosquito species, we conducted for the first time an inventory in the Aures region more particularly the wilaya of Batna (East of Algeria) from May 2017 to January 2020, we studied their diversity, abundance and distribution. The sampling is done by monthly surveys of the various localities chosen, using the dipping method to collect the larvae. In the various sites prospected, we were able to collect a total of 8275 mosquito individuals presented by nine species belonging to four different genera: Culiseta, Culex, Aedes and Anopheles of which the genus Culiseta is the best represented, particularly with the species Culiseta longiareolata (52.07%). It appears from what we have obtained that the Batna region reveals a significant diversity of mosquitoes. This study aimed to inventory the Culicidian species more broadly by surveys in several localities of Batna region at the level of different environments. This will allow us to know the faunistic composition of the region, to collect and record information on the vectors, their habitats and the conditions that favors their multiplication within a given area.
