摘要

A 2-year survey was carried out from May to November 2008 and 2009 to study the sand fly species composition its seasonal phenology and density in Apulia region (southern Italy) The study was conducted in a dog shelter located in a new residential urban district where Leishmania infantum is endemic Sand flies were collected using sticky traps from May to November at about 7-day intervals Temperature and relative humidity were recorded daily In December 2008 general environmental improvements (e g the ground was covered with gravel and the vegetation present inside the cages was removed to facilitate cleaning) were made in the study area The most diffused species during the whole study period were Phlebotomus perniciosus (2008 n=248 49 4% 2009 n=254 50 6%) followed by Phlebotomus neglectus (2008 n = 76 39 8% 2009 n = 115 60 2%) and Phlebotomus papatasi (2008 n = 5 50 0% 2009 n = 5 50 0%) Four specimens of Phlebotomus perfihewi were collected only in the first year The number of Sergentomyia minuta specimens collected increased considerably in the second (n = 548 86 2%) in comparison to the first year (n = 88 13 8%) The highest number of phlebotomine sand flies was collected in July and August when a mean temperature from 27 09 to 28 02 C and mean relative humidity from 47 28 to 56 36% were recorded The variations in phlebotomine sand fly species diversity and abundance recorded in this study were related to climatic and environmental factors Data here presented confirm that sand flies easily adapt to the urban envir
