Abstract

A utilização de galinheiro como modelo experimental na observação do comportamento de Psychodopygus intermedius, desenvolvida na região do Vale do Ribeira, Estado de São Paulo, Brasil, revelou uma estreita associação entre o flebotomíneo e biótopo artificial estudado. Sua maior densidade à margem da mata sugeriu a hipótese de estar adaptado ao efeito marginal. As investigações em ambiente florestal e extraflorestal demonstraram sua nítida preferência pelo último. Diversos aspectos discutidos explicam parcialmente a ocorrência de leishmaniose tegumentar nesse Estado.<br>The use of chicken roosts as experimental models for observing the behavior of Psychodopygus intermedius in the Ribeira River Valley region of the State of S. Paulo (Brazil), showed that there is a close association between the biotope studied and the phlebotomine sandfly. Its greater frequency along the edge of woods suggested the hypothesis of its adaptation to the edge effect. Investigation of forest and extraforest environments showed the fly's clear preference for the latter. Several of the aspects discussed in the paper partially explain the occurrence of cutaneous leishmaniasis in S. Paulo State
