Ecological aspects of Pintomyia fischeri and Migonemyia migonei in municipalities with Canine Visceral Leishmaniasis, State of São Paulo, Brazil.

The objective was to study the composition of sand fly species, the seasonal activity of the dominant species and correlation with average rainfall, sex association of the dominant species with domicile habitats and analyze different landscape scenarios for the two study sites in the municipalities of Itapevi and Mogi of the Crosses. Sandflies were captured with CDC(s) traps installed in three households at each study site for a period of 24 hours, biweekly for two years. A total of 2970 specimens were collected. The dominant species were P.fischeri and M.migonei. A statistically significant difference was registered between males and females of the two species in relation to the intra and peridomicile. The seasonal activity of both species showed a weak significant positive correlation with rainfall. The species P.fischeri and M.migonei may be potential vectors of CVL in the studied sites.

O objetivo foi estudar a composição das espécies de flebotomíneos, a atividade sazonal das espécies dominantes e a correlação com médias pluviométricas, associação de sexo das espécies dominantes com habitats domiciliares. Também analisar diferentes cenários da paisagem para os dois sítios de estudo nos municípios de Itapevi e Mogi das Cruzes. Os flebotomíneos foram capturados com armadilhas CDC(s) instaladas em três domicílios de cada sítio de estudo por um período de 24 horas, quinzenalmente por dois anos. Um total de 2.970 espécimes foram coletados. As espécies dominantes foram P.fischeri e M.migonei. Foi registrada diferença estatística significante entre machos e fêmeas das duas espécies em relação ao intra e peridomicílio. A atividade sazonal das duas espécies apresentou fraca correlação positiva significante com a chuva. As espécies P.fischeri e M.migonei podem ser potenciais vetores de LVC nos locais de estudo.(AU)
