Phlebotomine sandflies and factors associated with their abundance in the leishmaniasis endemic area of Attiki, Greece

Abstract

Leishmaniasis is a parasitic disease of animals and humans caused by several Leishmania species and transmitted by phlebotomine sandflies. The aim of the present study was to identify the species of field collected phlebotomine sandflies in the endemic area of the Attiki during 4 consecutive years, to isolate the Leishmania parasites from the infected sandflies, and identify possible factors associated with sandfly abundance in the area. A total of 542 trappings were made in 46 collection sites, in purely urban areas, periurban areas, and purely rural areas in Attiki. Out of the 3254 sandflies trapped, 1448 (44.43%) were female and 241 (16.64%) of the females were blood fed while Leishmania infantum DNA was detected in the 0.41% of them. Regarding sandfly species, the most prevalent was Phlebotomus tobbi (41.52%) followed by Sergentomyia minuta (27.44%), P. neglectus (14.83%), P. simici (11.08%), P. papatasi (3.68%), P. similis (0.89%), and P. alexandri (0.56%). Periurban areas were found to have the highest density of sandfly populations. © 2017, Springer-Verlag GmbH Germany, part of Springer Nature.
