Resumen:
Phlebotominae sand flies have been involved as vectors of Leishmania. In Argentina, Nyssomyia neivai andLeishmania. In Argentina, Nyssomyia neivai and
Nyssomyia whitmani are involved as the main vectors of American Tegumentary Leishmaniasis (ATL). In
the northeastern border of the country, an outbreak of ATL during 20042005 was associated with deforestation
and subsequent settlement of farmers close to the edge of the forest. The aim of this work was to
study the community composition of sand flies along time in farms located near primary and secondary
forest in two environments: houses and pigsties. The association of abundance with temperature and precipitation
was also evaluated for the most prevalent species. A total of 23,659 Phlebotominae belonging
to the genera Nyssomyia, Migonemyia, Pintomyia, Evandromyia, Micropygomyia, Sciopemyia, Dampfomyia,are involved as the main vectors of American Tegumentary Leishmaniasis (ATL). In

Psathyromyia and Brumptomyia were captured. Ny. whitmani, which was the most abundant species, andand Brumptomyia were captured. Ny. whitmani, which was the most abundant species, and
Migonemyia migonei, which was the second most abundant species, were present throughout the year.
Both species were positively associated with temperature, mostly up to 3147 days, and with precipitation
at 31 days before the sampling day. The abundance was higher in pigsties than in houses, but the
time pattern was positively associated between both environments. These results confirm that Ny. whitmani, which was the second most abundant species, were present throughout the year.

is the dominant species in the study area and its presence throughout the year indicates a potential
long period of ATL transmission. The presence of Mg. migonei as the second species in abundance is relevant,
because it has been described as a secondary vector of the parasites of ATL and a putative vector of
the agent of American Visceral Leishmaniasis. We discuss the role of the pigsty as the environment that
attract more sandflies, taking into account the number of sand flies captured there, the distance from the
home, and the association of sand fly abundance with each of the two environmentsMg. migonei as the second species in abundance is relevant,
