abstract
The present investigation took place in the region of Constantine in northeast of Algeria, during the period from April 2013 to October 2013 and from April 2014 to October 2014; she was conducted to study the biodiversity and chorology of Phlebotomian fauna in this region. For the sampling process, we adopted the technique of the adhesive traps deposited in various stations, where we explored internal biotopes (farms) and external ones (retaining walls). The results of the morpho-taxonomic study on the collected sand flies showed the presence of both types of sand flies: Sergentomyia and Phlebotomus. The identified species were 5 in the internal biotopes and 4 in the externalbiotopes. These are Sergentomyia minuta parroti Rondani 1843 (53.16%), Phlebotomus perniciosus Newstead 1911 (43.46%), Phlebotomus longicuspis Nitzulescu 1930 (2.84%), Phlebotomus perfiliewi Parrot 1930 (0.37%) and Phlebotomus papatasi Scopoli, 1786 (0.18%) identified in the internal biotopes. While in the external biotopes, the species identified were: Sergentomyia minuta parroti Rondani 1843 (51.01%), Phlebotomus perniciosus Newstead 1911 (39.60%), Phlebotomus longicuspis Nitzulescu 1930 (6.94%), Phlebotomus perfiliewi Parrot 1930 (2.46%). This inventory shows the presence of two species of subgenus Larroussius (Phlebotomus perfiliewi and Phlebotomus perniciosus); proven vectors of Leishmania infantum responsible for visceral leishmaniasis. The species Phlebotomus papatasi, vector of Leishmania major responsible for cutaneous leishmaniasis is also present.
