“…Our observations confirm the habit of this species coexisting preferably in the canopy of threes. The same findings were previously described in the Amazonian region , Azevedo et al 1993.Previous studies on natural infection made in Peixoto de Azevedo have demonstrated a possible association of that phlebotomine with L. (V.) braziliensis, the same parasite that has been isolated from patients. Tissue samples from the borders of lesions were inoculated into the feet of hamsters.…”

“…Their preference for mammals whose habitat are on the ground or at canopy level has contributed with information about the different cycles of leishmaniasis transmission. In the primary Amazonian forest in the North of Brazil, the species of Psychodopygus and Nyssomyia prevail, on the ground and in the tree canopy, respectively , Azevedo et al 1993. But this trend was not observed in Peixoto de Azevedo, for on the Beira-Rio Farm, Nyssomyia was prevalent on the ground and L. (N.) whitmani and L. (N.) antunesi, in the canopy.…”

“…The light trap CDC type has been systematically used in studies on sand flies in forest areas and/or in areas where there is leishmaniasis transmission , Aguiar et al 1985a, Gomes & Galati 1987, Dourado et al 1989, Azevedo & Rangel 1991, Azevedo et al 1993, Galati et al 1996, Brazil et al 2000, Barros et al 2000. In spite of the fact that this kind of collection does not allow access to the great number of species, which may constitute the local fauna (Shaw & Lainson 1972) Martins et al 1978, Young & Duncan 1994.…”

Key words: Lutzomyia umbratilis -Leishmania braziliensis -Phlebotominae -Mato Grosso -Brazil Environmental alterations in different regions of Brazil have been modifying the epidemiological profile of leishmaniasis for some decades. These changes have created high-risk areas for Leishmania infection (Lainson 1988, 1989, Walsh et al. 1993, Rangel 1995.The migration movements toward the Amazon Region that have taken place in the last three decades have been directly or indirectly supported by the Federal Government through colonization projects and road construction. Those migratory currents have produced considerable alterations in the environment and they have given rise to haphazard colonization models. Such environmental changes and new associations between man and nature have created new focuses of human disease: malaria and, especially of cutaneous leishmaniasis. Peixoto de Azevedo country, in the north of the State of Mato Grosso, is an area where such a chain of events has been recorded.The region was covered by primitive forest 25 years ago, but now there are over 100,000 inhabitants in the area, and their main interests have been agriculture and mining. These two activities account for the regions thriving economy followed by wood extraction and cattle raising. The economic development of the region has contributed to the changing in the environment and has brought the population into contact with vector sand flies and could explain the increase in the number of cases of (T Pereira, pers. commun.).This study aims to contribute to present knowledge on phlebotomine sand fly ecology the in the Central-West Region of Brazil. MATERIALS AND METHODSArea studied -Peixoto de Azevedo, a large country covering an area of 14,383 km 2 is located 661 km from Cuiabá, in the north of the State of Mato Grosso, at latitude 10 o 13'23"S and longitude 54 o 58'47"W (Fig. 1). The weather is hot and humid, with three dry months (equatorial climate), with an average yearly temperature of 26 o C, and annual rainfall ranging from 2,000 to 3,000 mm. The relief of the area presents a complex base made up of southern Amazon Plateau Residuals. Those plateaus, that interfluves with slopes at heights above 400 m are included in the Peripheral Amazon Basin, which also features mountain ridges carved in volcanic, sub-volcanic and metamorphic Precambrian rocks. The local vegetation is composed by an ecologically tense region, a small spot where two different vegetation types occur (Ama- zon Forest and savanna) (IBGE 1996). This region has been influenciated by human modifications (anthropic action). The local economy now is based on agricultural production (rice, corn, beans), cattle raising, timber extraction (cinnamon, jatobá and cedar), and lately, in less proportion on gold prospecting.Sand fly collections -In order to establish the two collection sites, some captures with Shannon trap were done. The station Beira-Rio Farm was approximately 22 km apart from station BR-080 (primary Forest). Sand fly collections were carried out mo...
