Abstract in Portuguese
As observações ecológicas sobre Psychodopygus intermedius desenvolvidas no Vale do Ribeira. Estado de São Paulo revelaram que este flebotomíneo teve dominância absoluta com nítida preferência por ecótopos artificiais. Nesse particular, o galinheiro experimental situado à margemoda mata apresentou sempre maior densidade, além de servir como abrigo a ambos os sexos. Por outro lado, a população mostrou ter comportamento eurítopo com densidades variáveis nos três ecótopos cuja pluviometria pareceu ter papel importante. Finalmente, se Ps. intermedius tem a capacidade de frequentar as habitações humanas e seus anexos, é lícito admitir sua tendência à domiciliação. Consequentemente, assume a condição de vetor principal da leishmaniose tegumentar no ambiente modificado neste Estado, onde se ressalta a existência de matas residuais encerrando focos ativos da doença.

Abstract in English
The ecological observations on Pychodopygus intermedius carried out in the Ribeira River Valley, State of São Paulo, Brazil, revealed absolute dominance of the sandfly and its clear preference to artificial biotopes. In this particular, the experimental chicken roost located border of woodlands showed always higher density and on the served as a breeding site for both sexes. On the other hand, the populations showed a eurotype behaviour with a variable density in three biotopes where the quantity of rainfall seemed to have an important role. Finally, as Ps. intermedius have been captured within human habitations and those of domestic animals with a high density, it is quite valid to admit that there is a tendency towards domiciliation of the insect. Consequently, it assumes the condition of being the main vector in modified environments in this State where the residual woodlands contain active foci of cutaneous leishmaniasis.
