Leishmaniose tegumentar americana: flebotomíneos de área de transmissão, no município de Pedro de Toledo, região sul do Estado de São Paulo, Brasil

Abstract

Resumo

Phlebotomine sand flies (Diptera, Psychodidae) in an American tegumentary leishmaniasis transmission area in northern Espírito Santo State, Brazil

“…The high frequency of phlebotomine sand flies in the disturbed habitat confirms observations by other authors in different regions of Brazil 2,14,15,16,17 . In Espírito Santo, Barros et al 2 suggested that the construction of human dwellings in the middle of banana groves creates a favorable environment for these insects by providing both shelter and abundant blood meal sources.…”

Phlebotomines (Diptera: Psychodidae) in forested areas of the Serra da Bodoquena, state of Mato Grosso do Sul, Brazil

“…So of the 23 species found on the Serra da Bodoquena, 22 were captured by this technique. The density obtained in this present study is not very different from that of the forested areas, using the same technique, as occurred on the Serra de Maracaju (3.6 insects/ trap) (Galati et al 1996), the vegetation of which is closely similar to that of the Serra da Bodoquena and also to that of Campo Grande city (1.02 insects/trap) (Oliveira et al 2003), both situated in the state of Mato Grosso do Sul (MS), as well as in the Atlantic vegetation domain of São Paulo, situated in the river basin of the Ribeira de Iguape (4.4 insects/trap) (Domingos et al 1998). On the other hand, this density (i.e., of 2.4 insects/trap) is much lower than that observed in the Amazon forest in the northern region of Mato Grosso (ca.…”

Distribution of sand flies (Diptera: Psychodidae) at different altitudes in an endemic region of American cutaneous leishmaniasis in the State of Espírito Santo, Brazil

“…Lu. intermedia is abundant in many endemic areas of ACL, where it has adapted to habitats modified by human activity, showing an increased predisposition to enter houses and bite both man and dogs (Falqueto 1995, Marzochi & Marzochi 1997, Domingos et al 1998). There are also records of natural infection with Leishmania (Forattini et al 1972, Rangel et al 1984.…”

“…Tropical climatic conditions and altitudes of up to 800 m above sea level (asl) favor transmission of Leishmania (Viannia) braziliensis (Mogollón et al 1977, Bonfante-Garrido 1983, Añez et al 1988, including in Brazil (Forattini et al 1972, Aguiar et al 1987, Azevedo & Rangel 1991, Passos et al 1993, Hermeto et al 1994, Domingos et al 1998, Gomes & Neves 1998, Rangel et al 1999.…”
