title: [Sandfly fauna (Diptera: Psychodidae) in a focus of American cutaneous leishmaniasis on the urban periphery of Manaus, State of Amazonas].
abstract: From August 2001 to July 2002, sand flies were collected from the bases of trees and, using CDC and Disney traps, from areas surrounding homes and forested areas in the São João community, on the urban periphery of Manaus, State of Amazonas. 4,104 specimens belonging to four subtribes, 13 genera and 49 species of the Phlebotominae subfamily were collected. The subtribe Psychodopygina predominated, with 3,403 (83%) specimens, especially of Nyssomyia umbratilis, Nyssomyia anduzei, Trichophoromyia eurypyga, Bichromomyia olmeca nociva and Bichromomyia flaviscutellata. The occurrences of Nyssomyia umbratilis and Nyssomyia anduzei, which have been incriminated as vectors for Leishmania (Viannia) guyanensis, and of Bichromomyia flaviscutellata and Bichromomyia olmeca nociva, for Leishmania (Leishmania) amazonensis, indicate that there is a risk of infection for people living in this area. Most (98.5%) of the sand flies were caught in the forested area. Nyssomyia anduzei and Bichromomyia olmeca nociva were collected from areas surrounding homes. The richness of vector species for Leishmania in this area shows the need for constant entomological surveillance.
