title: [Study of the vectorial competence of Lutzomyia intermedia (Lutz & Neiva, 1912) for Leishmania (Viannia) braziliensis, Vianna, 1911].
abstract: This paper investigated the vectorial competence of Lutzomyia intermedia (Diptera: Psychodidae) in Vale do Ribeira (SP) to strains of Leishmania (Viannia) braziliensis (Kinetoplastida: Trypanosomatidae), by means of a search for natural infection; exposure of wild and colonized females (F1) to the lesions of experimentally infected hamsters and transmission tests by bite. The natural infection and the transmission tests were negative. In the exposures of Lu. intermedia to infected lesions we found rates of 74% (123+/166 dissected) and 70% (115+/164 dissected) for the wild and colonized females respectively. The development of the parasites was compatible with the development model of Peripilaria. The susceptibility of the tested strains associated with the epidemiological indicators contribute to the vectorial role suspicion of Lutzomyia intermedia in the studied region.
