Objective: To identify the urban phlebotomine sandfly fauna in Ponta Pora, Mato Grosso do
Sul State, Brazil. Methods: The captures were undertaken from April 2009 to March 2010 with
CDC light traps in 14 ecotopes (intra and peridomicile) in different areas of the city, Shannon
traps being used in areas with abundant vegetation. Results: A total of 707 specimens were
captured with CDC light traps (565 males and 142 females) and 155 specimens (112 males and 43
females) with Shannon traps, a total of 862 phlebotomines. The specimens captured belonged
to eight species: Lutzomyia longipalpis (Lutz & Neiva, 1912), Evandromyia cortelezzii (Brethes,
1923), Sciopemyia sordelli (Shannon & Del Ponte, 1927), Pintomyia pessoai (Coutinho & Barretto,
1940); Pintomyia monticola (Costa Lima, 1932); Brumptomyia brumpti (Larousse, 1920); Nyssomyia
whitmani (Antunes & Coutinho, 1939) and Psathyromyia shannoni (Dyar, 1929). Lutzomyia
longipalpis, the main vector of Leishmania (Leishmania) chagasi, was the species most frequently
captured (97.03%) and also the most abundant according to the standardized abundance index
(SAI)=0.86. Conclusions: The highest species richness was captured, with CDC light traps, inside
the domiciles and the species diversity and evenness in the peridomicile, clearly indicating a
preference for anthropic environments.
