The development of Leishmania (Viannia) braziliensis in experimentally infected Lutzomyia intermedia, showed colonization of the hindgut from 48 h after the infective blood-meal, and the migration of flagellates to the foregut, with a massive infection of the cardia at the 5th day post infection. Up to 10 days following the infective blood-meal, very few parasites were seen in the pharynx and cibarium. The role of L. intermedia as a vector of cutaneous leishmaniasis is discussed according to the established criteria.
