“… Nyssomyia shawi was found to be in low abundance in most studies conducted in Rondônia; however, Gil et al (2003) recorded a high abundance of this species, which is similar to two different reports in Acre State ( Araujo-Pereira et al 2021 , Brilhante et al 2021 ), which observed that this species is amongst the most frequent sand fly species predominantly occurring in primary forest environments. This species could be involved in the maintenance cycle of trypanosomatids, including Leishmania .…”

BackgroundSandflies are insects important for the transmission cycles of the leishmaniases. Despite being studied since the 1960s in the State of Rondônia (Brazil), several gaps exist regarding our working knowledge of these insects. This study aimed to construct an up-todate database of sandflies using complementary information from the speciesLink database and the scientific literature, as well as to elaborate integrated abundance maps. We identified 153,155 records of sandflies captured in Rondônia between 1965 after exclusion, 147,258 reports (speciesLink -3,408, Rondônia studies -143,850) associated with 15 genera and 140 species were mapped. The most abundant species observed were

Background:The American cutaneous leishmaniasis (ACL) is expanding in peri-urban environments.Methods: An entomological survey was conducted in the area of the occurrence of an autochthonous urban case of ACL. Sandflies and a parasitological slide of the human case were submitted for molecular diagnosis.Results: Nyssomyia whitmani and Ny. antunesi were the most frequently collected species. Ny. whitmani and Bichromomyia flaviscutellata were positive for Leishmania guyanensis and L. lainsoni, respectively. The human case tested positive for L. lainsoni. Conclusions:Sandflies and Leishmania parasites present in urban forest may occur frequently in nearby domiciliary environments; thus, these areas must be monitored.

“…The subfamily Phlebotominae is widely distributed in Brazil, and the Amazon biome presents the largest number of species recorded, including most of the genera Bichromomyia , Nyssomyia , Psychodopygus , and Trichophoromyia which includes incriminated vectors of the etiological agents of cutaneous leishmaniasis (CL) [ 1 , 5 ]. The state of Acre, located in the southwest of the Brazilian Amazon, has a great diversity of sand fly species associated to different habitats, reservoirs, and protozoans [ 6 – 8 ], totaling 116 species of these insects [ 9 ], which increases the relevance of correct entomological monitoring in these localities.…”

DNA barcoding of sand flies (Diptera, Psychodidae, Phlebotominae) from the western Brazilian Amazon

The subfamily Phlebotominae comprises important insects for public health. The use of complementary tools such as molecular taxonomy is necessary for interspecific delimitation and/or discovery of cryptic species. Here, we evaluated the DNA barcoding tool to identify different species in the southwestern Brazilian Amazon. For this, we collected sand flies in forest fragments along the highway BR-317, in the municipality of Brasiléia, state of Acre, Brazil. The specimens were DNA-barcoded using a fragment of the cytochrome c oxidase subunit I (COI) gene. The sequences were analyzed to generate K2P pairwise genetic distances and a Neighbour-joining tree. The sand fly barcodes were also clustered into Molecular Operation Taxonomic Units (MOTU) using Automatic Barcode Gap Discovery (ABGD) approach. A total of 59 COI sequences comprising 22 nominal species and ten genera were generated. Of these, 11 species had not been sequenced before, thus being new COI sequences to science. Intraspecific genetic distances ranged between 0 and 4.9%, with Pintomyia serrana presenting the highest values of genetic distance, in addition to having been partitioned into three MOTUs. Regarding the distances to the nearest neighbour, all species present higher values in relation to the maximum intraspecific distance, in addition to forming well supported clusters in the neighbour-joining analysis. The DNA barcoding approach is useful for the molecular identification of sand flies from Brasiléia, state of Acre, and was efficient in detecting cryptic diversity of five species which can be confirmed in future studies using an integrative approach. We also generated new COI barcodes for Trichophoromyia auraensis, Nyssomyia shawi, and Psychodopygus paraensis, which may play a role in the transmission of Leishmania spp. in the Brazilian Amazon.
