A leishmaniose tegumentar americana é notificada no Distrito Federal, mas seus transmissores ainda são desconhecidos. O objetivo deste trabalho foi pesquisar a infecção natural por Leishmania por meio da reação em cadeia da polimerase (PCR) em flebotomíneos capturados na Região Administrativa de Sobradinho, nas localidades de Boa Vista e Fercal. Foram capturadas as espécies Lutzomyia whitmani (89%), Lutzomyia bacula (7%) Lutzomyia davisi (3%) e Lutzomyia termitophila (1%). O maior percentual de flebotomíneos foi encontrado no peridomicílio (58%). A reação em cadeia da polimerase teve resultado negativo para a presença de Leishmania nos exemplares capturados. É provável que possa estar havendo transmissão peridomiciliar e que Lutzomyia whitmani seja o principal vetor. _______________________________________________________________________________________ ABSTRACT / Leishmaniasis is caused by protozoan of the genus Leishmania which are transmitted by the bite of insects belonging to the family Phlebotominae (Diptera: Psychodidade). Cutaneous leishmaniasis is reported in the Federal District, but their transmitters are still unknown. The objective of this study was to investigate the natural infections by Leishmania by polymerase chain reaction (PCR) in sand flies in the Sobradinho Administrative Region, in the localities of Boa Vista and Fercal. Species were captured Lutzomyia whitmani (89%), Lutzomyia bacula (7%), Lutzomyia Davis (3%) and Lutzomyia termitophila (1%). The highest percentage of sand flies were found in peridomicile habitats (58%). The polymerase chain reaction was negative for the presence of Leishmania in specimens captured. It is possible that there may be transmission and peridomicile Lutzomyia whitmani is the main vector.
