Tiger mosquito under surveillance in western Algeria

Culicidae are Nematoceran Diptera that transmit various animal and human diseases, An entomological study is conducted in 2019, in three sites of the Algerian far west coast to verify the presence of the vector Aedes albopictus. Based on eleven productive sites (4 created and 7 surveyed), the Culicidae populations are composed of five species, four of which belong to the subfamily Culicinae and only one to the subfamily Anophelinae. The stands are poor in species, very little diversified and of low regularity. The most abundant species is Culiseta longiareolata (69%) which is found in all the sites. Omnipresent, plastic, it remains strongly dominant in these man-made sites. Orthopodomyia pulcripalpis comes second with 22%, followed by Culiseta fumipennis with 7.6%, and more rarely Culiseta annulata with 0.9% and Anopheles claviger with 0.5%. The species are all aggregated in distribution. This modest work has not confirmed the presence of the tiger mosquito in this region and the species present do not appear to be involved in the transmission of important pathogens
