“…This period coincides with the late winter and spring. This result is different than that showed by Galati et al (2010) in the Iporanga municipality, São Paulo state, where the predominance of the species occurs in the summer, however, it corroborates the observations of Odorizzi & Galati (2007) in the northwestern region of São Paulo state.…”

“…The presence of Ny. neivai exclusively in the Bocaina region is perhaps due to its proximity to the open area of degraded pasture, since this species predominated in anthropized areas of the interior of São Paulo (Condino et al 1998;Odorizzi & Galati 2007).…”

ABSTRACT. Phlebotomines (Diptera, Psychodidae) in the Ribeira Valley Speleological Province -1. Parque Estadual Intervales (PEI), São Paulo state, Brazil. The identification of the sandfly fauna and investigation of some ecological aspects of its populations in areas frequented by tourists of the PEI, an Atlantic forest reserve with many caves, were the objective of this study. Captures were undertaken monthly from January 2001 to December 2002, with automatic light traps installed in 13 ecotopes, including caves, forests, domiciliary and peridomiciliary environments, and by aspiration in armadillo burrows. Additionally, although not at regular intervals, Shannon traps were installed in forests and anthropic environments, aspirations were made on cave walls, among roots and fallen leaves, and some insects were captured while biting researchers. A total of 891 sandflies belonging to 21 species were captured. Six hundred specimens representing 19 species were captured with light traps, 215 in anthropic (2.24 insects/trap) and 385 in extra-domiciliary (1.46 insects/trap) environments. Brumptomyia troglodytes was the most abundant species (the Standardised Index of Species Abundance = 0.705). Pintomyia monticola predominated in the Shannon traps and showed anthropophilic and diurnal activity. Psathyromyia pascalei predominated in the aspirations; the largest number being in armadillo burrows. Eleven species were captured in caves; although some might be troglophiles, the majority used these ecotopes as resting places. Nyssomyia intermedia, Nyssomyia neivai and Migonemyia migonei, implicated in the transmission of cutaneous leishmaniasis in the Southeastern Brazilian region, were all found, though in such low densities as to suggest minimal risk of the disease in the PEI. KEYWORDS. Atlantic forest; cave; leishmaniasis; vectors.RESUMO. Phlebotominae (Diptera, Psychodidae) na Província Espeleológica do Vale do Ribeira -1. Parque Estadual Intervales (PEI), estado de São Paulo, Brasil. A identificação da fauna flebotomínea e de alguns aspectos ecológicos de suas populações em áreas freqüentadas por turistas no PEI, situado em reserva de mata Atlântica, constituem-se nos objetivos deste estudo. As capturas foram mensais de janeiro/2001 a dezembro/2002, com armadilhas automáticas luminosas em 13 ecótopos, incluindo cavernas, matas e peridomicílio e aspiração em tocas de tatus. Sem intervalos regulares, foram realizadas capturas com armadilhas de Shannon na mata e ambientes antrópicos, aspiração em paredes de cavernas e entre raízes e folhedo e em membros da equipe quando picados por flebotomíneos. No total foram capturados 891 flebotomíneos pertencentes a 21 espécies. Com as armadilhas automáticas luminosas capturou-se 19 espécies e 600 espécimes, 215 em ambiente antrópico (2,24 insetos/armadilha) e 385 em ambiente natural (1,46 insetos/armadilha). Brumptomyia troglodytes foi a mais abundante, com o índice de abundância das espécies padronizado = 0,705. Pintomyia monticola predominou nas armadilhas de Shannon, mostrando-se...

“…In the Ribeira valley region, N. neivai seems to be more likely than N. intermedia to overcome adverse conditions in open cultivated areas and adapt to anthropic changes to the environment [ 27 ]. Thus, deforestation and changes in land use could have led N. neivai to occupy new areas and replace existing species in the Plateau area as observed by Odorizzi & Galati [ 28 ] and Casanova et al [ 29 , 30 ]. Both species have been found naturally infected by L. braziliensis in other Brazilian states [ 31 , 32 ]; in the Plateau areas of São Paulo state, N. neivai (named N. intermedia at that time) was found naturally infected by unidentified flagellates [ 33 , 34 ].…”

Geographical distribution of American cutaneous leishmaniasis and its phlebotomine vectors (Diptera: Psychodidae) in the state of São Paulo, Brazil

BackgroundAmerican cutaneous leishmaniasis (ACL) is a re-emerging disease in the state of São Paulo, Brazil. It is important to understand both the vector and disease distribution to help design control strategies. As an initial step in applying geographic information systems (GIS) and remote sensing (RS) tools to map disease-risk, the objectives of the present work were to: (i) produce a single database of species distributions of the sand fly vectors in the state of São Paulo, (ii) create combined distributional maps of both the incidence of ACL and its sand fly vectors, and (iii) thereby provide individual municipalities with a source of reference material for work carried out in their area.ResultsA database containing 910 individual records of sand fly occurrence in the state of São Paulo, from 37 different sources, was compiled. These records date from between 1943 to 2009, and describe the presence of at least one of the six incriminated or suspected sand fly vector species in 183/645 (28.4%) municipalities. For the remaining 462 (71.6%) municipalities, we were unable to locate records of any of the six incriminated or suspected sand fly vector species (Nyssomyia intermedia, N. neivai, N. whitmani, Pintomyia fischeri, P. pessoai and Migonemyia migonei). The distribution of each of the six incriminated or suspected vector species of ACL in the state of São Paulo were individually mapped and overlaid on the incidence of ACL for the period 1993 to 1995 and 1998 to 2007. Overall, the maps reveal that the six sand fly vector species analyzed have unique and heterogeneous, although often overlapping, distributions. Several sand fly species - Nyssomyia intermedia and N. neivai - are highly localized, while the other sand fly species - N. whitmani, M. migonei, P. fischeri and P. pessoai - are much more broadly distributed. ACL has been reported in 160/183 (87.4%) of the municipalities with records for at least one of the six incriminated or suspected sand fly vector species, while there are no records of any of these sand fly species in 318/478 (66.5%) municipalities with ACL.ConclusionsThe maps produced in this work provide basic data on the distribution of the six incriminated or suspected sand fly vectors of ACL in the state of São Paulo, and highlight the complex and geographically heterogeneous pattern of ACL transmission in the region. Further studies are required to clarify the role of each of the six suspected sand fly vector species in different regions of the state of São Paulo, especially in the majority of municipalities where ACL is present but sand fly vectors have not yet been identified.
