RESUMO:

In order to know the phlebotomine fauna of Sítio Portão de Pedra, municipality of Sumidouro,
Rio de Janeiro, catches were made in 2009 and 2010, in a cave, around the cave and in the
Atlantic Forest in the region, with a view to a case report of American cutaneous leishmaniasis
was recorded in 2007. 1756 sandflies belonging to 14 species were captured, of which 11 were
Lutzomyia: Lutzomyia gasparviannai Martins, Godoy & Silva, 1962b, L. edwardsi
(Mangabeira, 1946), L. tupynambai (Mangabeira) , 1942b), L. hirsuta hirsuta (Mangabeira,
1942b), L. whitmani (Antunes & Coutinho, 1939), L. davisi (Root, 1934), L. migonei (France,
1920), L. microps (Mangabeira, 1942a). ), L. cortelezzii (Brethés, 1923), L. quinquefer (Dyar,
1929), L. sp. and three Brumptomyia species: Brumptomyia brumpti (Larrouse, 1920), B.
guimaraesi (Coutinho & Barreto, 1941a) and B. sp. L. gasparviannai was predominant in all
collection sites (67.3%), being more frequent in the forest (73.8%). Torrential rains and
landslides, which occurred from January 11 to 12, 2011, mainly on the mountain slopes of the
highland region of Rio de Janeiro state, would affect the ecology of sandfly species at the Portão
de Pedra site, municipality of Sumidouro, State of Rio de Janeiro, Brazil. The predominant
species, in 2009/2010, was L. gasparviannai with 67.3% of the collected specimens. This
research confirms the prevalence of this species, but with a marked difference (47.2%). L.
gasparviannai predominated in the collections made in the cave, around the cave and in the
Atlantic Forest. The fauna diversity was higher in the previous period, with 14 species collected,
while in the present study there were 9 species. The species of medical importance, L. whitmani,
L. migonei, L. hirsuta hirsuta and L. davisi were more quantitative (65) in 2009/10, while in
this period there were 38 specimens. 2323 sandflies belonging to 9 species were captured, being
8 of the genus Lutzomyia: L. gasparviannai, L. edwardsi, L. tupynambai, L. hirsuta hirsuta, L.
whitmani, L. migonei, L. intermedia, L. sp. and one species of Brumptomyia: B. brumpti. It is
reported that nematode-infected L. edwardsi found in 2009 and 2010, five years later, found
Wuchereria bancrofti infected L. gasparviannai, both species were collected in the cave. In
order to evaluate the relationship between climatic indices and the three most frequent species,
a Poisson regression was performed. The results showed that the relative humidity showed
significant differences (p <0.01) for L. gasparviannai, L. edwardsi and L. tupynambai. For
temperature only L. tupynambai was significant. In the cave and Atlantic Forest collections,
significant differences occurred in the three species (p <0.01). When comparing the Cave
Surroundings and the Atlantic Forest and the periods 2009 and 2010 with 2015 and 2016, the

X

species L. edwardsi and L. tupynambai showed significant results (p <0.01). To evaluate the
differences between the SISA results, an analysis of variance (ANOVA) was performed, which
found significant differences between the values SISA of the three species (p - value = 0.004).
