Ecological aspects of phlebotomine fauna (Diptera, Psychodidae) of Serra da Cantareira, Greater S o Paulo Metropolitan region, state of S o Paulo, Brazil Aspectos ecológicos da fauna flebotomínea (Diptera, Psychodidae) da Serra da Cantareira, Regi o metropolitana da Grande S o Paulo, Estado de S o Paulo, Brasil

Human cases of American cutaneous leishmaniasis (ACL) have been recorded in Serra da Cantareira, in the Greater S o Paulo Metropolitan Region, where two conservation units are situated, the Parque Estadual da Cantareira and the Parque Estadual Alberto L fgren. The present study aimed to identify the sandfly fauna and some of its ecological aspects in these two parks and their surrounding area to investigate Leishmania sp. vectors. The captures were undertaken monthly from January to December 2009, from 6:00 p.m. to 6:00 a.m., with automatic light traps installed in forests and peridomicile areas and with modified black/white Shannon traps in the peridomicile. A total of 12 species and 5,436 sandflies were captured: with automatic light traps (141), Shannon traps (5,219) and attempting to bite the researchers while they were conducting the collection in Shannon traps (76). Pintomyia fischeri and Migonemyia migonei were the most abundant species. Pi. fischeri predominated in all three kinds of captures (49%, 88.8% and 65.8%, respectively). Mg. migonei was the second most prevalent in Shannon traps (10.0%) and attempting to bite the researchers (22.4%). Pi. fischeri females were significantly more attracted to black and those of Mg. migonei to white Shannon traps. A positive and significant correlation was observed between the numbers of Pi. fischeri and the mean of minimum relative humidity values on the fifteen days prior to capture, while there was a negative and significant correlation between the relative humidity on the capture day and the two most abundant species. The anthropophilia and high frequencies of Pi. fischeri and Mg. migonei suggest that both species may be transmitting ACL agents in this region. Casos humanos de leishmaniose tegumentar americana (LTA) têm sido registrados na Serra da Cantareira, regi o da Grande S o Paulo, onde se situam o Parque Estadual da Cantareira e o Parque Estadual Alberto L fgren. O estudo teve como objetivo identificar a fauna flebotomínea e alguns de seus aspectos ecológicos nos dois parques e área adjacente, para investigar vetores de Leishmania sp. As capturas ocorreram de janeiro a dezembro de 2009, das 18 às 06 horas, com armadilhas automáticas luminosas instaladas em matas e peridomicílios, e com armadilhas de Shannon modificadas, nas cores branca e preta, em peridomicílio. Foram capturadas 12 espécies e 5.436 flebotomíneos por armadilhas automáticas luminosas (141), armadilhas de Shannon (5.219) e tentando picar os pesquisadores enquanto coletavam na armadilha de Shannon (76).
