ABSTRACT. Phlebotomines (Diptera, Psychodidae) in the Speleological Province of the Ribeira Valley: 3. Area of hostels for tourists who visit the Parque Estadual do Alto Ribeira (PETAR), state of São Paulo, Brazil. The study characterizes some ecological aspects of the phlebotomine fauna in an endemic area of cutaneous leishmaniasis (CL) situated in the Serra district, Iporanga municipality where the hostels for tourists visiting the PETAR are located. Captures were undertaken on a smallholding and a small farm situated near the hostels, monthly between January/2001 and December/2003 with automatic light traps (ALT) in pigsty, henhouse and veranda of a domicile at the two sites, and in peridomicile of the small farm also with black/white Shannon traps. With the ALT a total of 87,224 phlebotomines representing 19 species and also two hybrids of Nyssomyia intermedia (Lutz & Neiva) and Nyssomyia neivai (Pinto) and two anomalous specimens were captured. The standardized index species abundance was for Ny. intermedia = 1.0 and Ny. neivai = 0.935. The highest frequencies of the smallholding occurred in the pigsty, the Williams' mean/ capture for Ny. intermedia being 63.7 specimens and for Ny. neivai 29.2, and on the small farm, in the hen-house, Ny. intermedia 402.6 and Ny. neivai 116.2. A total of 863 phlebotomines (Ny. intermedia: 75.4%; Ny. neivai: 24.3%) were captured with black/ white Shannon traps; females of both species being predominant in the white trap. The high frequencies of Ny. intermedia and Ny. neivai, both implicated in CL transmission, indicate the areas presenting risk of the disease.KEYWORDS.

Área de pousadas para turistas que visitam o Parque Estadual do Alto Ribeira (PETAR), estado de São Paulo, Brasil. O estudo teve como objetivo caracterizar alguns aspectos ecológicos da fauna flebotomínea em área endêmica de leishmaniose tegumentar situada do Bairro Serra, município de Iporanga, onde se situam pousadas para turistas que visitam o PETAR. As capturas foram realizadas em uma chácara e em um sítio, mensalmente, entre janeiro de 2001 e dezembro de 2003, com armadilhas automáticas luminosas (AAL) em chiqueiro, galinheiro e varanda do domicílio de ambos os locais, e no sítio, também com armadilhas de Shannon branca/preta. Capturou-se com as AALs um total de 87.224 flebotomíneos, representando 19 espécies, mais dois híbridos de Nyssomyia intermedia (Lutz & Neiva, 1912) e Nyssomyia neivai (Pinto, 1926) e dois espécimes anômalos. Ny. intermedia apresentou o índice de abundância das espécies padronizado = 1,0 e Ny. neivai = 0,935. Na chácara, ambas predominaram no chiqueiro, com a média geométrica de Williams/captura para Ny. intermedia = 63,7 espécimes e para Ny. neivai = 29,2, e no sítio, no galinheiro, Ny. intermedia = 402,6 e Ny. neivai = 116,2. Capturou-se nas armadilhas de Shannon branca/preta 863 flebotomíneos: Ny. intermedia (75,...

“…which may have arisen as a result of recent allopatry (~ 250,000 years). The discovery in the Brazilian state of São Paulo of insects morphologically similar to N. intermedia s.s. but with DNA mitochondrial sequences apparently more characteristic of the related N. neivai indicates that separation of the two species was very recent, not yet complete and/or interbreeding occurred under particular conditions and at certain times of the year (Marcondes et al 1997). Morphological variations in the number of tergal spots provided the first evidence that L. longipalpis was a species complex (Mangabeira 1969).…”
