“…P. papatasi is the proven vector of L. major and P. sergenti, P. alexandri and P. bergeroti are potential vectors of L. tropica (Doha et al, 1994;2014). P. langeroni and P. papatasi were recorded from El Agamy, Alexandria Governorate (El .Sawaf et al, 1984) and P bergeroti from Sinai (El Sawaf et al, 1987). Lane (1986) reviewed the sandfly fauna of Egypt and described eight Phlebotomus species: P. papatasi, P. bergeroti, P. alexandri, P. sergenti, P. kazeruni, P. orientalis, P. arabicus and P. major and 13 Sergentomyia species namely S. tiberiadis , S.…”

“…Initial survey, following detection of the 1st human visceral leish maniasis (VL) case, reported the existence of two sandfly species Phlebotomus papatasi and P. langeroni (El Sawaf et al, 1984). Phlebotomus papatasi is the vector of cuta neous leishmaniasis (CL) in Egypt (Khalil, 1934 andCahill et al, 1966) and P. langeroni was considered to be the pro bable vector of VL based on its taxonomic position in the subgenus Larroussius, its behaviour in the field, its asso ciation with man and dogs (El Sawaf et al, 1989) and its experimental susceptibility to L. donovani .…”

SummaryThe dispersal of Phlebotomus papatasi (Scopoli) and P. langeroni Nitzulescu was studied using the mark-release-recapture techniques in the summer of 1987, at El Hammam, Matrouh governorate. In one experiment, 739 specimens (472 P. papatasi and 267 P. langeroni) were marked with fluorescent powders and released in 5 batches at one point. In a 2nd experiment, 1,524 specimens (571 P. papatasi and 953 P. langeroni) were marked and released in 6 batches at the same point. In the 1st exp., 116 (15.7 %) marked sand-flies were recaptured 1-9 nights after release. In the 2nd exp., 218 (14.3 %) marked sand-flies were recaptured 1-13 nights after release. All recap tured flies were examined by UV lamp. Male sand-flies stayed near the release point and were not captured at distances > 600 m in the 1st exp., but in the 2nd exp., they travelled a longer distance > 1,400 m. This was also true for blood fed females which gene rally remained within 400 m for the first three nights then dispersed to distance of 600 m in the 1st exp. and > 1,400 m in the 2nd exp. Unfed females quickly moved away from the relase point, sometimes to distances of 900 m or more in the 1st exp. and 1,500 m in the 2nd exp. Sandfly movement was affected by wind velocity, wind direction and presence of hosts. The dispersal of Phlebotomus sand flies confirms that leishmaniasis can be dispersed readily by the move ment of the vector. ont été marqués et relâchés en 6 lots au même point. Dans la première expérience, 116 phlébotomes marqués (15,7 %) ont été recapturés 1 à 9 nuits après leur relâchage. Dans la seconde expé rience, 218 phlébotomes marqués (14,3 %) ont été recapturés 1 à 13 nuits après leur relâchage. Tous les phlébotomes ont été exa minés à la lampe à ultra-violets. Les mâles sont restés près du point de relâchage ; ils n'ont pas dépassé 600 m dans la première expérience et 1 200 m dans la seconde. Il en est de même pour les femelles gorgées qui, en général, sont restées à 400 m pendant les trois premières nuits, puis se sont dispersées à 600 m dans la première expérience et plus de 1 400 m dans la seconde. Les femelles à jeun se dispersent rapidement à partir du point de relâ chage, parfois jusqu'à 900 m et plus dans la première expérience et 1 500 m dans la seconde. La mobilité des phlébotomes est influencée par la force du vent, sa direction et la présence des hôtes. La dispersion des phlébotomes confirme que l'expansion de la leishmaniose est favorisée par la mobilité du vecteur.

“…In El Agamy (Alexandria, Egypt) where visceral leishmaniasis occurs (Tewfick et al, 1983) and P. lange roni is the suspected vector in the area (El Sawaf et al, 1984); important sand fly breeding sites were determined. These are mainly stone piles on which litter and garbage are thrown, and rodent burrows.…”
