“…At BR-080, Psychodopygus was predominant, whereas L. (P.) llanosmartinsi had the highest rate on the ground and L. (P.) c. carrerai, in the canopy. This evidence may can corroborate the existence of a qualitative and quantitative imbalance in the regional phlebotomine fauna.Among the local sand fly fauna, some species are referred to by Young and Duncan (1994) and Lainson and Grosso, Brazil (1997-1998 L. (N.) whitmani was present at both collecting stations; however, its density was lower at BR-080, than on the Beira-Rio Farm, where species of the sub-genus Nyssomyia prevailed.The relationship between the primary forest and the density of the Psychodopygus species has also been observed in Bolivia (Le Pont & Desjeux 1986) and in Brazil (Biancardi et al 1982, Aguiar & Soucasaux 1984, Aguiar et al 1985b, Ready et al 1986). …”

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...

“…subgenera Psychodopygus (46,7%) em nossas coletas, é semelhante aos resultados encontrados por vários pesquisadores em áreas de floresta primária na Amazônia Brasileira Fraiha et al, 1978;Arias & Freitas, 1982;Ready et al, 1986), assim como a sua tendência a predominar em coletas com isca humana. No entanto, Ready et al (1986) Fraiha et al (1978) Freitas (1982) reportaram uma diminuição na fauna de flebotomíneos deste subgênero durante a estação de menor precipitação, em áreas ecologicamente similares, utilizando as mesmas técnicas de coleta. Porém, os autores não mencionam se algumas das coletas por eles realizadas foram após ligeiras chuvas durante esta estação.…”

“…Em outras áreas da Amazônia Brasileira foi coletada apenas com armadilhas luminosas CDC e em número reduzido (Arias & Freitas, 1982;Biancardi et al, 1982;Castellón et al, 1994). As exceções foram os estudo de Barrett et al (1996) no município de Tefé -Amazonas, onde esta espécie ocupou o terceiro lugar em ordem de abundância, e de Ready et al (1986) no município de Jarí -Pará, onde esta espécie predominou em floresta úmida.…”

Um total de 1030 flebotomíneos, pertencentes a 14 espécies, foram coletados com armadilha tipo Shannon e isca humana, nos meses de Julho e Agosto de 1991, nos horários das 18:00 h. às 21:00 h., nas localidades de San Juan, San Pedro e 25 de Diciembre localizadas na Amazônia Peruana. As fêmeas foram mais abundantes do que os machos (96,98% e 3,02% respectivamente). Os subgêneros Psychodopygus (49,27% e 7 spp. coletadas) e Nyssomyia (48,79% e 4 spp. coletadas) comportaram o maior número de espécies e indivíduos. As espécies Lutzomyia richardwardi (48,4%) e L. carrerai (29,2%) foram as mais abundantes. Na localidade de San Juan foi coletado o maior número de indivíduos (55,2%), porém o maior número de espécies foi obtido na localidade de 25 de Diciembre. Quanto a estratégia de coleta, o mesmo número de espécies (12 spp.) foram obtidos com ambas as armadilhas, porém um maior número de indivíduos foi capturado com a técnica de isca humana.

“…gomezi are poorly registered in the western Amazonian areas of the state (Rebêlo et al 2000a,b), being the presence of these species fi rst recorded in the eastern section of Maranhão. These species also occur in other regions of the Brazilian legal Amazonia (Biancardi et al 1982, Castellón et al 1994. Lutzomyia saulensis was already reported to the cerrado region of Tocantins state (Andrade Filho et al 2001).…”
