ABSTRACT
American cutaneous leishmaniasis (ACL) occurs in epidemic outbreaks and in sporadic cases with small annual variation in the Pontal of Paranapanema, SP. There is little research on the sandfly fauna of this region. The last outbreaks were related to the Movement of the Landless Workers (MST) and with the ecological tourism in preserved forest of the Parque Estadual do Morro do Diabo (PEMD). AIM:
identification of the sandfly fauna within the PEMD, mainly anthropophilic species already incriminated as vectors of ACL, as well as their seasonality, hourly frequency and data of the behavior. M&M The captures were undertaken with CDC light and Shannon traps from 600 pm to 1000 pm, monthly from May 2000 to December 2001. The temperature and relative humidity data were registered at hourly intervals.RESULTS:
The captured species were Brumptomyia brumpti, Nyssomyia neivai, Nyssomyia whitmani, Pintomyia fischeri and Pintomyia pessoai. The P. pessoai predominated (34.39 percent) and N. neivai was less found (0.74 percent), only being captured in CDC traps. Shannon trap captured more sandflies (63.01 percent) than the CDC traps (36.99 percent). Despite the environmental degradation anthropophilic species, indicates favorable bioecological conditions for persistence of vectors and potential transmission of leishmaniasis.RESUMO
LCA ocorre em surtos epidêmicos e casos esporádicos com pequena variação anual no Pontal do Paranapanema, SP. Há pouca pesquisa sobre a fauna flebotomínea na região. Os últimos surtos estão relacionados ao MST e turismo ecológico na floresta do Parque Estadual do Morro do Diabo (PEMD). OBJETIVO:
identificar a fauna flebotomínea no PEMD, principalmente as espécies antropofílicas já incriminadas como vetores da LCA, também, sua sazonalidade, horários e dados de comportamento. M&M As capturas foram feitas com armadilhas CDC e Shannon das 18 às 22h, mensalmente de maio de 2000 a dezembro de 2001. Dados de temperatura e umidade relativa foram registrados com intervalo de uma hora.RESULTADOS:
As espécies capturadas foram Brumptomyia brumpti, Nyssomyia neivai, Nyssomyia whitmani, Pintomyia fischeri e Pintomyia pessoai. A P. pessoai predominou (34,39 por cento) e a N. neivai foi a menos encontrada (0,74 por cento), capturada com a CDC. A Shannon capturou mais flebotomíneos (63,01 por cento) que a CDC (36,99 por cento). Apesar da degradação ambiental espécies, antropofílicas foram encontradas, indicando condições bioecológicas para persistência de vetores e potencial transmissão da leishmaniose.
