Sand fly vectorial ecology in the state of São PauloGomesAlmério de Castro Universidade de São Paulo, Faculdade de Saúde Pública, Departamento de Epidemiologia São Paulo Brasil 091994893457460Ecological aspect of sand fly distribution in the state of São Paulo, Brazil are described. The main man-biting species are Lutzomyia whitmani, Lu.pessoai, Lu.intermedia, Lu.migonei and Lu.fischeri. Their primary habitat is the forest but latter three of the above species are also encountered in domiciliary environment. Sylvatic species such as Lu.flaviscutellata bite man only rarely and Psychodopygus ayrozai seems to be more anthropophilic. The survival of sand flies in the residual forest and in cultivated areas where man has nearly destroyed the forest almost completely is analyzed. Over the last ten years the incidence of human American cutaneous leishmaniasis (ACL) has been increasing: human cases occurring within several municipalities in which there is overlapping with the distributon of domiciliary Lu.intermedia. New ACL microfoci are appearing in the state of São Paulo and these call for further study.American cutaneous leishmaniasissand flyecologyLutzomyiaFull text available only in PDF format.Texto completo disponível apenas em PDF.
