“…Species identification was made by examining the morphology of the pharyngeal armatures and spermathecae of female flies and the external genitalia of males. In this area, the male of Phlebotomus perniciosus Newstead did not present the typical morphology (Guernaoui et al 2005b). To differentiate it from that of Phlebotomus longicuspis Nitzulescu, we examined both the form of copulatory valves and the number of coxite hairs.…”

Cutaneous leishmaniasis (CL) due to Leishmania tropica Wright has become an increasingly important problem in Al-Haouz province, Morocco. The objective of this paper was to undertake a retrospective analysis of CL between 2000 and 2006 and to study the sandfly fauna for the first time in this focus. The consultation of bulletins, registers and monthly and annual reports published by local and national medical services permitted a global synthesis of CL in Al-Haouz between 2000 and 2006. Sandflies were collected using sticky-paper traps in five selected stations in two communes, Ourika and Sti Fadma, the most affected by CL in Al-Haouz. Overall, 2,648 sandflies, belonging to five species of Phlebotomus and three of Sergentomyia, were collected. Phlebotomus sergenti Parrot (14.5%) was found in all studied stations where it was associated with domestic and peridomestic habitats. Based on this first report on ecology of sandflies and epidemiology of CL, Al-Haouz seems to be a typical focus of L. tropica and P. sergenti like the other Moroccan foci. Two communes, Sti Fadma and Ourika, constituted an important CL micro-focus in this region. Considering their economical importance (trade and tourism), they contribute probably to the dissemination of Leishmania parasite in bordering regions.

“…It can be confused with P. longicuspis, but has been differenciated by the number of coxite hairs which is higher in P. longicuspis sensu stricto as described on specimens from Morocco and Spain. (Benabdennbi et al, 1999;Martin-Sanchez et al, 2000;Pesson et al, 2004;Guernaoui et al, 2005).…”

Phlebotominae (Diptera: Psychodidae) of human leishmaniosis sites in Tunisia

Summary :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 Larroussius 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 arid bioclimatic stages and P. longicuspis in the visceral leishmaniosis focus of saharan bioclimate. In the zoonotic cutaneous leishmaniosis foci, P. papatasi 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. perniciosus 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. Résumé

The nocturnal activity of phlebotomine sandflies (Diptera: Psychodidae) was studied "at an epidemic focus" on human cutaneous leishmaniasis due to Leishmania tropica Wright in Chichaoua province, in Morocco. Sandflies were collected using light and sticky-paper traps changed at 2-h intervals, inside and around houses, in August and October 2004. Overall, 633 sandflies, belonging to six species of Phlebotomus and three of Sergentomyia, were collected. Sandfly activity was nocturnal and higher at twilight. Several activity patterns were observed according to the species. Phlebotomus (Paraphlebotomus) sergenti Parrot, 1917, the suspected vector of L. tropica in this focus, was caught during each collection performed from 1900 to 0500 hours, the numbers of species caught peaked at 1900-2100 hours. There were seasonal variations of the nocturnal activity, which could be related to the variations in temperature and relative humidity.
