Abstract
Aspects of phlebotomine behavior were investigated in the city ofCampoGrande, Mato
Grosso do Sul state. The insects were captured weekly during December 2003 to November 2005, with
Centers for Disease Control light traps at seven different sites including forests and residential areas.
In total, 11,024 specimens (7,805 males and 3,219 females) were collected, from which 9,963 (90.38%)
were identiÞed as Lutzomyia longipalpis, the proven vector of American visceral leishmaniasis agent.
The remaining 9.62% comprised 21 species. L . longipalpis was the most frequent species in all sampled
sites, and the Þrst in the ranking of standardized species abundance index. In residential areas this
species clearly predominated in the peridomicile (90.96%), in contrast to the intradomicile (9.04%);
in animal shelters, it was more numerous in hen houses and prevailed at ground level, inside, and at
forest edge around the residences; this aspect is worrying because this insect may remain sheltered
in forested environments during the use of insecticides in homes. In the forest environment, other
probable or proven vector of cutaneous leishmaniasis agents were also captured such as Lutzomyia
whitmani ( Nyssomyia whitmani, sensu Galati), Lutzomyia antunesi ( Nyssomyia antunesi, sensu
Galati), and Lutzomyia flaviscutellata ( Bichromomyia flaviscutellata, sensu Galati).
