مستخلص: Entomological investigations were conducted for the first time in urban forest remnants of Porto Velho, state of Rondônia, Brazil, to explore the transmission dynamics of Leishmania. Sand fly collections were carried out at ten sites, encompassing both canopy and ground strata, from October to December 2021. A total of 1,671 sand flies were collected, representing 42 species within 12 genera. Nyssomyia Antunesi (n = 384) and Psychodopygus davisi (n = 111) were the most abundant species. Molecular analyses targeting the V7V8 region (18S gene) unveiled the presence of sequences 100% identical to Leishmania infantum in females of Bichromomyia flaviscutellata (1), Nyssomyia Antunesi complex (6), Nyssomyia umbratilis (1), Nyssomyia sp. (1), Psychodopygus ayrozai (1), Ps. davisi (3), Psychodopygus paraensis (1), and Sciopemyia sordellii (1). Sequences 100% similar to Trypanosoma minasense were found in two samples of the Nyssomyia Antunesi complex, and two samples of Sc. sordellii presented 100% identity to a Trypanosoma sp. strain, previously identified in this same sand fly in Rondônia. Sequencing of Cytb fragment suggested Homo sapiens, Dasypus novemcinctus and Tamandua tetradactyla as the blood source for distinct sand flies. The identification of sequences similar to L. infantum in sand flies collected in urban forest fragments is noteworthy, correlating with the recent local and regional occurrence of autochthonous cases of human visceral leishmaniasis. However, further studies are imperative to ascertain the presence of hosts/reservoirs and evaluate the risk of L. infantum transmission to humans.
