ABSTRACT
The objective of this study was to determine the abundance and diversity of the species and their presumed vectorial role in the transmission of Cutaneous Leishmaniasis (CL). Research on sand flies (Diptera Psychodidae) was carried out in two municipalities in the Ribeira River Valley in the State of Paraná, southern Brazil. One, Adrianópolis, is an endemic area of CL and the other is a recent outbreak area (Cerro Azul). A total of 432 specimens were collected from residential, peri-domestic and wild environments. According to the data obtained, for each ecotope studied, the statistical analysis has shown that two lines of the Lutzomyia intermedia population coexist and that the quantity of specimens from L. intermedia s.l. is significantly different from L. intermedia s.s. in all environments (χ2=9.943; DF=2; p=0.07). The prevalence of L. intermedia (93.28%) in the ecotopes studied suggests that it is the main vector of leishmaniasis. The succession of vector species and their involvement in the epidemiological cycle of L. braziliensis is discussed in this article(AU)
RESUMEN
El objetivo de este trabajo fue determinar la abundancia y diversidad de las especies y su supuesto papel vectorial en la transmisión de Leishmaniasis Cutánea (LC). La investigación sobre flebótomos (Diptera Psychodidae) se llevó a cabo en dos municipios en el Valle del Río Ribeira en el Estado de Paraná, sur de Brasil. Las regiones estudiadas fueron Adrianópolis, área endémica de LC, y Cerro Azul, que se reporta como zona de brote reciente. Se recolectaron un total de 432 especímenes de ambientes residenciales, peri-domésticos y silvestres. El análisis estadístico realizado, a partir de los datos obtenidos para cada ecotopo estudiado, mostró que coexistían dos linajes de la población de Lutzomyia intermedia y que la cantidad de especímenes de L. intermedia s.l. fue significativamente diferente de L. intermedia s.s. en todos los entornos (χ2=9,943; GL=2; p=0,07). La prevalencia de L. intermedia (93,28%) en los ecotopos estudiados sugiere que es el principal vector de la leishmaniasis. La sucesión de especies de vectores y su participación en el ciclo epidemiológico de L. braziliensis se discute en este artículo(AU)
