为了确定突尼斯利什曼病疫源地的白蛉种群，通过三个昆虫季节（2002-2003-2004）在19个内脏和皮肤利什曼病地区，位于6个生物气候带进行了昆虫学调查。白蛉收集是基于放置在人类利什曼病病例周围的光和粘性陷阱。共采集白蛉12种8,722只。我国北方疫源地的洛罗斯亚属优势种、西南疫源地的帕帕塔斯白蛉亚属优势种及中部的共优势种与婴儿利什曼原虫和利什曼原虫的分布相一致。主要在突尼斯。在西南部梅特拉维的历史人畜共患皮肤利什曼病疫源地发现的低密度可能表明当地人口的高能力。研究的phlebotomine定居点表现出较低的特定多样性，在大多数研究的网站。在洛婴儿区的优势种分别为：湿润生物气候阶段皮肤利什曼病疫源地的P. perfiliewi、半干旱和生物气候阶段皮肤和内脏利什曼病疫源地的P. perniciosus和撒哈拉生物气候阶段内脏利什曼病疫源地的P. longicuspis。在人畜共患的皮肤利什曼病疫源地中，木瓜疟原虫是优势种。在著名的东南部皮肤利什曼病疫源地，由于L。Sagricki、P. sergenti和P. perniciosus是优势种。在L. P. pemiciosus在某些地点是优势种，而在其他地点则非常罕见。在这些地点，亚属Paraphlebotomus总是存在与P. alexandri比P. sergenti更高的丰度。
In order to identify the phlebotomine sandfly populations in Tunisian leishmaniosis foci, an entomological survey was carried out through three entomological seasons (2002-2003-2004) in 19 visceral and cutaneous leishmaniosis areas, located in six bioclimatic zones. Sandfly collections were based on light and sticky traps placed around human leishmaniosis cases. 8,722 phlebotomine sandflies belonging to 12 species were collected. The dominance of subgenus Lorroussius species in northern foci, Phlebotomus papatasi in south-western foci and their co-dominance in the centre of the country is in accordance with the distribution of Leishmania infantum and L. major in Tunisia. The low density found in the historical zoonotic cutaneous leishmaniosis focus of Metlaoui in the south-west may indicate the high competence of the local populations. Studied phlebotomine settlements have showed a low specific diversity in most of the studied sites. In L. infantum areas, the dominant species were respectively: P. perfiliewi in the cutaneous leishmaniosis site of the humid bioclimatic stage, P. perniciosus in the cutaneous and visceral leishmaniosis foci of semi-arid and and bioclimatic stages and P. longicuspis in the visceral lershmaniosis focus of Saharan bioclimate. In the zoonotic cutaneous leishmaniosis foci, P. papatosi was a dominant species. In the well-known southeastern foci of cutaneous leishmaniosis due to L. killicki, P. sergenti was a dominant species with P. perniciosus. In the central emerging foci of L. killicki, P. pemiciosus was a dominant species in some sites whereas it was very rare in others. In these sites, the subgenus Paraphlebotomus was always present with a higher abundance of P. alexandri than P. sergenti.
