“…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). …”

“…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...

Abstract Abstract Abstract The phlebotomine sandfly fauna of a primary forest reserve at Morretes (eastern Paraná State) was studied, using CDC-like light traps, one night per month, at canopy and ground level, between April 1995 and March 1996. A total of 3,106 insects were collected, identified as belonging to nine species. Lutzomyia ayrozai and Lu. geniculata were predominant, seven other species also being present. Monthly mean temperature, rainfall and the temperature of the collection night significantly influenced the numbers of Lu. ayrozai while the two first factors influenced the numbers of Lu. geniculata, besides the collected quantities of females of the two species. The influence of the factors on Lu. ayrozai numbers was more immediate than in those of Lu. geniculata. Numbers of both species and of the females of Lu. geniculata collected in different seasons, but not at the different heights, varied significantly. Differences between the behaviour of Lu. ayrozai in Morretes and in other regions could be attributed to environmental differences and/or to regional variations in the species, which could constitute species complexes. Hourly variations of collections were different in the species and seasons. Key-words: Key-words: Key-words: Key-words: Key-words: Phlebotominae. Fauna. Seasonal variation. Psychodidae.

Resumo Resumo ResumoResumo Resumo A fauna de flebotomíneos de uma reserva de floresta primária em Morretes (leste do Estado do Paraná) foi estudada, utilizando armadilhas luminosas tipo CDC, uma noite por mês, no nível do solo e da copa, entre abril de 1995 e março de 1996. Um total de 3.106 insetos foi coletado. Lu. ayrozai e Lu. geniculata foram predominantes, além de outras sete espécies. A temperatura média mensal, a pluviosidade e a temperatura na noite de coleta influenciaram significativamente as quantidades de Lu. ayrozai e os dois primeiros fatores influenciaram Lu. geniculata, além das quantidades de fêmeas coletadas de ambas as espécies. A influência do aumento dos fatores nas quantidades de Lu. ayrozai foi mais imediata que nas de Lu. geniculata. As quantidades coletadas de ambas as espécies e das fêmeas de Lu. geniculata nas estações, mas não nas alturas, foram significativamente diferentes. As diferenças entre os comportamentos de Lu. ayrozai em Morretes e em outras regiões poderiam ser atribuídas a diferenças ambientais e/ou a variações regionais na espécie, que poderia constituir um complexo de espécies. As variações horárias nas coletas foram diferentes nas espécies e estações.
