During 2012–2015, an entomological survey was conducted as part of a phlebotomine (Diptera: Psychodidae) monitoring program in an area influenced by the Santo Antônio do Jari hydroelectric system (Amapá State, Brazil). The purpose was to study aspects of Amazon/Guianan American cutaneous leishmaniasis (ACL) vectors subjected to stresses by anthropogenic environmental changes. For sampling, CDC light traps were positioned 0.5, 1, and 20 m above ground at five capture locations along the Jari River Basin. Fluctuations in phlebotomine numbers were analyzed to determine any correlation with rainfall, dam waterlogging, and/or ACL cases, from May 2012 to March 2015. We captured 2,800 individuals, and among 45 species identified, Bichromomyia flaviscutellata, Nyssomyia umbratilis, and Psychodopygus squamiventris s.l. were determined to be the main putative vectors, based on current knowledge of the Amazon/Guianan ACL scenario. Rainfall, but not complete flooding, was relatively correlated with phlebotomine fluctuation, mainly observed for Ps. squamiventris s.l., as were ACL cases with Ny. umbratilis. Behavioral changes were observed in the unexpected high frequency of Bi. flaviscutellata among CDC captures and the noncanopy dominance of Ny. umbratilis, possibly attributable to environmental stress in the sampled ecotopes. Continuous entomological surveillance is necessary to monitor the outcomes of these findings.

“…Gil et al 3 complement that the high number of L. davisi captured in Shannon-type traps reflects its anthropophilic habit, while Azevedo et al 19 reports that the high L. whitmani density may be associated with the changes in the original vegetation and the better adaptation to new environmental conditions. In the areas studied other vectors of ACL were identified, such as L. flaviscutellata, the main vector of Leishmania (Leishmania) amazonensis, which has been also found to be parasitized by Leishmania (Viannia) guyanensis in the French Guiana 24 ; L. umbiquitalis, the vector of Leishmania (Viannia) lainsoni in Brazil 25 ; L. complexa, species considered to be a Leishmania (Viannia) braziliensis vector 26 ; Leishmania carrerai is considered to be a Leishmania (Viannia) braziliensis vector according to Grimaldi et al 27 , who has characterized the parasite in phlebotomine sandflies as naturally infected in the Brazilian Amazon.…”

“…In contrast, the weaker presence of LRV along the coastal area was presumably due to the low density of vectors and reservoirs implying a low parasite transmission in this more urbanized area. 23,24 Ecologic and epidemiologic factors related to Amazon region might be involved in the repartition of Leishmania parasites susceptible to harbor the LRV. 18 Concerning the type of biological material used for the search of LRV in all previous studies, this search was performed on human biopsies containing low amounts of the amastigote form of the parasite.…”

Abstract. In South America, the presence of the Leishmania RNA virus type 1 (LRV1) was described in Leishmania guyanensis and Leishmania braziliensis strains. The aim of this study was to determine the prevalence distribution of LRV1 in Leishmania isolates in French Guiana given that, in this French overseas department, most Leishmania infections are due to these parasite species. The presence of the virus was observed in 74% of Leishmania spp. isolates, with a highest presence in the internal areas of the country.
