Resumo

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.
