Flebotomíneos do Estado de Tocantins, Brasil (Diptera: Psychodidae)

Abstract

Between 1997-1998, the authors carried out sporadic collection of sand flies in the municipalities of Paraíso de Tocantins, Monte do Carmo, Porto Nacional and Monte Santo all in the Tocantins State of northern Brazil. Human bait was used in Monte Santo and a battery operated light trap in other municipalities. The ecotypes chosen for the traps were in the peridomiciles, inside the houses, in the forest and the orchard. We identified 2,677 sand flies, belonging to 32 species. The most abundant species of sand flies were Lutzomyia whitmani, Lutzomyia longipalpis, Lutzomyia carmelinoi, Lutzomyia evandroi, Lutzomyia longipennis and Lutzomyia antunesi. Collections from the forest showed greater diversity of species, while the largest number of sand flies were caught around the houses. Several species known or suspected to be vectors of Leishmania in other regions of Brazil were captured.

Fauna of phlebotomine sand flies (Diptera, Psychodidae) in areas with endemic American cutaneous leishmaniasis in the State of Mato Grosso do Sul, Brazil

“…whitmani and Ny. antunesi, the latter presenting a highly anthropophilic behavior (Andrade Filho et al 2001) and they were found naturally infected by flagellates in the State of Pará (Ryan et al 1984;Silveira et al 2002). Bichromomyia flaviscutellata, a species involved in the transmission of Leishmania (Leishmania) amazonensis in several regions of Brazil, including Mato Grosso do Sul Dorval et al 2010), was also captured.…”

Diversidade e abundância de flebotomíneos do gênero Lutzomyia (Diptera: Psychodidae) em áreas de mata do nordeste de Manacapuru, AM

“…No Novo Mundo, o gênero Lutzomyia é o de maior importância, com algumas espécies implicadas na transmissão dos agentes causais das leishmanioses, bartoneloses e arboviroses. Na América Latina, a leishmaniose tem sido historicamente associada a ambientes fl orestais (Andrade-Filho et al 2001, Peterson & Shaw 2003.…”
