Natural infections of Pintomyia verrucarum and Pintomyia maranonensis by Leishmania (Viannia) peruviana in the Eastern Andes of northern Peru.

ABSTRACT: The natural infection of sand flies by Leishmania was investigated in Andean areas located between the Central and Eastern Cordilleras of northern Peru where cutaneous leishmaniasis caused by Leishmania (Viannia) peruviana is endemic. Sand flies were captured at five locations along the Utcubamba River in the Department of Amazonas, and morphologically identified under a microscope. Among 422 female sand flies dissected, the most dominant species was Pintomyia verrucarum (320 flies), followed by Pi. maranonensis (83 flies), Pi. robusta (13 flies), and Lutzomyia castanea (6 flies). Genetic analysis of sand flies from these areas together with those from other areas revealed that individuals of Pi. verrucarum were closely related regardless of morphological variation of their spermathecae.
