Abstract
Peixoto de Azevedo is located in the north of State of Mato
Grosso, where environmental alterations led to an outbreak of American cutaneous
leishmaniasis in the 80s. The parasite from patients was characterized as
Leishmania (V.) braziliensis. The aim of this study is to contribute to
the sand fly ecology of Central-West Brazil. Captures were carried out monthly
using CDC light traps. Twenty-six species of sand fly were characterized;
among which Lutzomyia (Lutzomyia) spathotrichia, L. runoides and L. (Psychodopygus)
llanosmartinsi were recorded in the State of Mato Grosso for the first time.
L. (Nyssomyia) whitmani, L. (N.) antunesi, L. (L.) spathotrichia, L. (P.)
c. carrerai, L. (P.) complexa, L. (P.) lainsoni and L. (N.) umbratilis constituted
92.4% of the local fauna, among which L. (N.) whitmani and L. (N.) antunesi,
accounting for about 53% of the fauna at the stations of capture. On the
vertical distribution of sand flies on the Beira-Rio Farm, L. (N.) whitmani
and L. (N.) antunesi prevailed at ground level and in the canopy, respectively,
whereas on the BR-080, L. (P.) llanosmartinsi was prevalent on the ground
and L. (P.) c. carrerai, in the canopy. It is suggested that L. (N.) umbratilis
is the local vector.
