Abstract

Leishmaniases are zoonotic diseases with outbreaks influenced by environmental factors that can alter their epidemiological profiles. They are transmitted to humans and other vertebrates through the bite of a female phlebotomine infected with parasites of the Leishmania genus. The aim of this study was to conduct an entomological survey of the phlebotomine fauna to determine the distribution of potential vectors of leishmaniases, as well as to diagnose Leishmania spp. and evaluate food content. A sample study on potential leishmaniases vectors was conducted in an Environmental Protection Area (EPA) and Tinguá Federal Biological Reserve (TFBR), Nova Iguaçu municipality, in Rio de Janeiro State. Light traps were used to collect insects in the two study areas from September 2019 to March 2020. The data were obtained from six monitoring stations (MSs): MS1, MS2 and MS3 (EPA), and MS4, MS5 and MS6 (TFBR). Traps were installed in intradomicile, peridomicile, and residual forests in the EPA, while they were set up in wild animal burrows and rock formations in the TFBR. Phlebotomine samples (Diptera, Psychodidae) obtained from different MS's were used to estimate the standardized index of species abundance (SISA), diagnose specimens as Leishmania spp., and analyse the blood food content of the female sand flies. Seven primary or potential vectors were detected in relation to the total number of collected sand flies. These included Nyssomyia intermedia in the intradomicile, peridomicile, and residual forests of the EPA. This species was not detected in the TFBR, but other potential vectors were observed in both areas. During the diagnosis of Leishmania spp. in the sand flies, one specimen of Psychodopygus hirsutus hirsutus was positive for Leishmania (Viannia) braziliensis in the peridomicile (MS3). A specimen of Psychodopygus davisi was observed feeding on Tamandua tetradactyla in MS5 (TFBR), a potential reservoir of Leishmania. The presence of primary vectors, potential vectors, L. (V.) braziliensis, and a natural reservoir indicated the possible existence of a sylvatic and domestic transmission cycle in the American tegumentary leishmaniasis region.

INTRODUCTION

Leishmaniases are characterized by a group of diseases defined as zoonoses caused by digenetically flagellated protozoa of the order Kinetoplastida and family Trypanosomatidae, whose etiological agents are parasites of the genus Leishmania Ross. They are widely distributed and occur in 98 countries in Central America, South America, Africa, India, East and Central Asia, and on the shores of the Mediterranean (Alvar et al., 2012; Ruiz‐Postigo et al., 2021; WHO, 2016). Due to the clinical complexity of the disease and the diversity of Leishmania species, vectors, and domestic or wild reservoirs, different transmission cycles can occur (Desjeux, 2004; Maia‐Elkhoury et al., 2018; OPS, 2023). The distribution of Leishmaniases is associated with poverty and social, economic, and environmental conditions that directly influence its epidemiology (Alvar et al., 2006; Franke et al., 2002; Maia‐Elkhoury et al., 2016). As a result, Leishmaniasis can be observed in urban areas of several large cities in Brazil. The Metropolitan Region of Nova Iguaçu, State of Rio de Janeiro, Brazil, where socio‐environmental degradation is linked to a long history of the inability to manage natural and social assets, leading to outbreaks of viral and parasitic diseases, can be included in this context. Outbreaks, in addition to behavioural issues, are also linked to a lack of public safety, sanitation, and educational policies (Prefeitura Municipal de Nova Iguaçu, 2021).

Over the past 30 years, several outbreaks of American tegumentary leishmaniasis (ATL) have been recorded in Brazilian municipalities. The presence of Nyssomyia intermedia has been highlighted in studies of potential vectors in the state of Rio de Janeiro, suggesting that it is the main vector of Leishmania (Viannia) braziliensis (Aguiar et al., 2014; Azevedo et al., 2015; Gouveia et al., 2012; Meneses et al., 2005; Pita‐Pereira et al., 2005; Rangel et al., 2018). However, other species, such as Migonemyia migonei (Pita‐Pereira et al., 2005; Rangel et al., 2018; Rangel & Lainson, 2009), Pintomyia fischeri (Aguiar et al., 2014; Pita‐Pereira et al., 2011; Rangel et al., 2018), Evandromyia edwardsi (Capucci et al., 2023; Serra e Meira et al., 2022) and Psychodopygus davisi (de Souza et al., 2016; Gil et al., 2003; Rangel et al., 2018), found in the State of Rio de Janeiro, have been mentioned as potential vectors for L. (V.) braziliensis and the latter, together with Ps. hirsutus hirsutus (Gil et al., 2003) and Ps. ayrozai (Rangel et al., 2018; Rangel & Lainson, 2009; Vilela et al., 2013) to L. (V.) naiffi. From 2007 to 2024, 1164 cases of ATL were reported in the State of Rio de Janeiro, of which the municipality of Nova Iguaçu was responsible for 1% of the records, being the tenth largest in number of cases. For AVL, 142 cases were recorded in the state in the same period, with Nova Iguaçu reporting one case (SINAN, 2025). The aim of this study was to describe the composition of sand fly fauna and detect potential vectors of Leishmania spp. in the Tinguá district, an ATL‐endemic area in the State of Rio de Janeiro, southeast Brazil.

MATERIALS AND METHODS

Study area

The study was carried out in the Tinguá District, located in the far north of the municipality of Nova Iguaçu, in the State of Rio de Janeiro. More than 27% of the territory is represented by Conservation Unit areas, characterized as the Atlantic Forest biome (Prefeitura de Nova Iguaçu, 2022).

The Environmental Protection Area (EPA) has rural and peri‐urban characteristics, as well as an important tourist flow due to its landscape, which forms a contiguous territory to the Tinguá Federal Biological Reserve (TFBR) and covers an area of approximately 5400 ha in the northern region of the municipality (Figure 1).

The TFBR is in the Serra do Mar Biodiversity Corridor, in the Atlantic Forest biome in the State of Rio de Janeiro, approximately 60 km from the capital. It is located between latitudes 22°22′20″S and 22°45′00″S, and longitudes 43°40′00″W and 43°05′40″W. It has 26,260 hectares distributed among the municipalities of Nova Iguaçu (56%), Duque de Caxias (37%), Petrópolis (4%), and Miguel Pereira (3%).

This reserve is extremely important for the conservation of fauna, flora, and abiotic resources. The forest formations are Submontane Dense Ombrophilous, Montane Dense Ombrophilous and Altomontane Dense Ombrophilous. The climate in the region is tropical highland according to the Köppen classification, characterized by an average temperature of the coldest month that is always above 18°C and a short dry season that is offset by high rainfall totals (IBAMA, 2006) (Figure 1).

The sand flies species were collected at the EPA and inside the TFBR between September 2019 and March 2020. The monitoring stations (MSs) were chosen according to the criteria established by the Ministry of Health (2017) (Table 1).

Phlebotomine collected

HP light traps were used (Pugedo et al., 2005) and the original nylon cages were adapted with plastic pots (Fuzari‐Rodrigues et al., 2013) containing 250 mL of 80% alcohol. Traps were installed between 3 and 4 p.m. on the first day and removed between 9 and 10 a.m. on the fourth day. Traps were installed at different collect sites and MSs. Seven traps were set in the EPA: one in MS1 in the peridomicile (backyard), three in MS2 and three in MS3 in the intradomicile (balcony), peridomicile (chicken coop or corral), and residual forest areas. Three traps were set up in the TFBR, i.e., one in each MS. These were set up inside the reserve in rock crevices, holes in trees and animal burrows.

Phlebotomine processing and taxonomic identification

After separating the sand flies from the other insects, they were subjected to clarification and diaphanization (Vilela et al., 2018). Species names were abbreviated according to Marcondes (2007) for taxonomic classification, and species were identified by observing morphological characteristics using the dichotomous key proposed by Galati (2024).

Detection of Leishmania spp. DNA

Female (not engorged) sand flies were identified taxonomically (the head and the last three abdominal segments were sectioned for mounting and specific identification with the rest of the body sent for molecular analysis), separated individually into Eppendorf tubes labelled according to the collect area, species and sex, and sent to the laboratory for molecular assays. Males were used as controls for all stages of the diagnostic test, and females were analysed individually for the parasite according to Lins et al. (2002) and Pita‐Pereira et al. (2005). The samples were processed in the lysis buffer (10 mM Tris–HCl pH 9.2 containing 10 mM EDTA and 100 μg/mL proteinase K) and stored (−20°C) until the total DNA was extracted. DNA was extracted from the lysates using the Wizard SV Genomic DNA Purification System (PROMEGA) according to the manufacturer's specifications. All stages of DNA extraction were monitored by including negative control samples (male insects collected in the field), and all materials used in this stage were properly decontaminated with chlorine and UV exposure.

For the Hot‐start PCR multiplex reaction, two pairs of primers that simultaneously amplify a 120 bp product, referring to Leishmania kDNA (in the case of positive female samples), and a 220 bp product, corresponding to sand fly DNA (in the case of all samples containing males and females), were used. The first pair amplifies the conserved kDNA minicircle region: primer A [5′ GGC CCA CTA TAT TAC ACC AAC CCC 3′] and primer B [5′ GGG GTA GGG GCG TTC TGC GAA 3′] (Passos et al., 1996); the second pair amplifies a phlebotomine‐specific constitutive gene (cacophony): 5Llcac [5′ GTG GCC GAA CAT AAT GTT AG 3′] and 3Llcac [5′ CCA CGA ACA AGT TCA ACA TC 3′] (Lins et al., 2002). All amplified products were visualized using 2% agarose gel electrophoresis and stained using Nancy‐520.

The amplified PCR product was also analysed using solid‐phase hybridization and the Dot‐Blot technique. A subgenus‐specific or species‐specific probe, marked with biotin at the 5' end, revealed using a chemiluminescence solution was used.

Food source detection

For the analysis of food content, female (engorged) collected and taxonomic identification (the head and the last three abdominal segments were sectioned for mounting and specific identification with the rest of the body sent for molecular analysis) were individually separated in Eppendorf tubes labelled according to the collect area, species and sex, and sent to the laboratory for molecular testing. Primers that amplify the cytochrome b gene (cyt b) were used: 3′ CCC CTC AGA ATG ATA TTT GTC CTC A 5′ and 3′ CCA TCC AAC ATC TCA GCA TGA GA AA 5′ (Peña et al., 2012) and the products obtained for this gene were purified using the Wizard SV PCR Clean‐up System kit (PROMEGA) and sequenced with the same primers used for PCR. Sequencing was carried out on an automatic sequencer (ABI PRISM BigDye Terminator Cycle Sequencing) at the Oswaldo Cruz Foundation (IOC) (Genomic Platform ‐ DNA sequencing, PDTIS‐FIOCRUZ). The obtained sequences were aligned and compared with those deposited in the NCBI nucleotide database [http://blast.ncbi.nlm.nih.gov/Blast].

Analysis of collected sand fly species caught in the EPA and TFBR

The abundance of species at the MSs was estimated using the standardized index of species abundance (SISA) (Roberts & His, 1979). The analysis considered samples from six MSs: intradomicile (MS2 + MS3), peridomicile (MS1 + MS2 + MS3), and residual forest (MS2 + MS3) in the EPA, and TFBR (MS4 + MS5 + MS6). Phlebotomines caught in a light trap were considered a single sample.

Shannon diversity index

To evaluate and compare differences in the composition of the sand fly community at each monitoring station, the Shannon‐Wiener diversity index (H') (Shannon, 1948) was used, and to assess whether there were significant differences between the diversity indices, the t‐test was applied, with a significance level of 5%, using the Past 3.16 software (Hammer et al., 2001).

Analysis of collected sand fly species in the EPA and TFBR

Thematic maps were drawn to show the spatial distribution of the potential vectors collected in the study areas. The data were obtained by georeferencing the sampling sites using geographical coordinates obtained in the field with a portable Global Positioning System (GPS) device. Cartographic bases were obtained from the IBGE geographic database [https://downloads.ibge.gov.br/], and when available, regional and local bases were obtained directly from the Nova Iguaçu Municipal Department of the Environment, Agriculture, Economic Development, and Tourism.

All analyses were conducted using R version 4.4.2 (R Core Team, 2024). To assess spatial autocorrelation, global Moran's I was computed for each species, using a k‐nearest neighbours approach with k = 5 to ensure full connectivity of the spatial weight matrix given the limited number of sites. Moran's I and associated p‐values were calculated with the spdep package version 1.3–10 (Bivand & Wong, 2018). To map sites with higher abundance of each species, interpolated surfaces were generated for each species based on Inverse Distance Weighting (IDW). A regular spatial grid with 100 × 100 cells was created, buffered by approximately 500 metres from the sampling sites to aid visualization. IDW interpolation was performed separately for each species using the gstat package version 2.1–3 (Gräler et al., 2016). Final maps were designed in QGIS version 3.34.12‐Prizren (Graser et al., 2025) using standard WGS84 datum. SISA values were mapped with a white‐to‐dark red colour ramp from 0 to 1 to highlight subtle differences in lower abundance. Values were categorized as low (0.01–0.24), medium (0.25–0.74) or high (0.75–1).

RESULTS

Were collected during the period of the 7‐month, 2162 specimens identified, 50.8% of which were females. Sixteen species belonged to the genera Psychodopygus (3), Nyssomyia (1), Psathyromyia (3), Evandromyia (2), Pintomyia (2), Micropygomyia (1), Migonemyia (1), and Brumptomyia (3). The genus Migonemyia did not occur in the EPA, whereas the genus Nyssomyia was not detected in the TFBR.

Psychodopygus hirsutus hirsutus was the species with the highest SISA (0.41), followed by Ps. davisi with a value of 0.37. The possible vectors Ps. hirsutus hirsutus, Ps. davisi, Ny. intermedia, Ps. ayrozai, Pi. fischeri, Ev. edwardsi and Mg. migonei were found in different MSs with SISA values ranging from 0.02–0.41. These species accounted for 96% of the total number of specimens collected from the two study areas (Table 2).

Possible vectors.

When analysing the collects in the different MSs, 75% (1622 specimens) of the specimens occurred in the EPA, a place with the highest number of collected specimens, and 25% (540 specimens) in the TFBR. The ratio between the total number of specimens and the number of collects was 33.8 specimens in the EPA and 30 in the TFBR.

Of the six MSs, only collections made at MS1 were negative, located in a peri‐urban area; at the other stations, 50.7%, 24.3%, 16%, 4.9% and 4.1% corresponded to the total number of specimens caught at MS2, MS3, MS4, MS5 and MS6, respectively.

Of the total number of specimens collected in the EPA, 50.7% were at MS2, where Ps. hirsutus hirsutus (0.36) exhibited the highest SISA, followed by Ps. davisi (0.24). Ps. ayrozai, Ny. intermedia, Pi. fischeri and Ev. edwardsi also occurred at this station, with SISA values varying from 0.04 to 0.07. At MS3, where 24.3% of all specimens were collected, the SISA values of Ps. davisi were highest (0.52), followed by Ps. hirsutus hirsutus (0.48) and Ny. intermedia (0.47), respectively. Ps. ayrozai (0.11) was also detected at this station. In TFBR, specimen collections in MS4 (16%) were more efficient than in MS5 (4.9%) and MS6 (4.1%) In MS4, there were five potential vectors with their respective SISAs estimated at 0.97 (Ps. hirsutus hirsutus), 0.78 (Ps. davisi and Ps. ayrozai), and 0.19 (Pi. fischeri and Ev. edwardsi). In MS5, there were five vectors: Ps. hirsutus hirsutus (0.42), Ev. edwardsi (0.16), Mi. migonei (0.09), Ps. davisi (0.06), and Ps. ayrozai (0.04), whereas in MS6 there were Ps. hirsutus hirsutus (0.50), Mi. migonei (0.17), and Ps. davisi and Ev. edwardsi (0.06) (Figure 2).

When estimating the SISA indices of potential vectors at the three collect sites in the EPA, values of 0.17, 0.35 and 0.09 were observed for Ny. intermedia in the intradomicile, peridomicile, and residual forests, respectively; 0.13, 0.14 and 0.70 for Ps. hirsutus hirsutus in the intradomicile, peridomicile and residual forest, respectively; 0.17, 0.27 and 0.79 for Ps. davisi in the intradomicile, peridomicile, and residual forest, respectively; while Pi. fischeri indices, in the peridomicile (0.05) and residual forest were 0.29 for Ps. ayrozai and 0.07 for Ev. edwardsi (Figure 3).

Psychodopygus davisi, Ps. hirsutus hirsutus, Ps. ayrozai, Pi. fischeri and Ev. edwardsi occurred in the EPA and the TFBR. Mg. migonei did not occur in the EPA, and Ny. intermedia did not occur in the TFBR. The highest estimated SISA value in the EPA was 0.38 (Ps. davisi) followed by 0.32 (Ps. hirsutus hirsutus) and 0.23 (Ny. intermedia), while it was 0.51 (Ps. hirsutus hirsutus) and 0.24 (Ps. davisi) in the TFBR (Figure 4).

The area that presented the highest specific richness (number of species) was MS5 (TFBR), with S = 11, followed by the forest areas of MS2 (EPA) and MS4 (TFBR), both with S = 9, with the forest in MS2 standing out for representing the highest number of collected individuals (N = 1100). The greatest diversity was found in the peridomicile in MS2 (H' = 1.609), despite the lower number of collected individuals. Next, MS5 (tree hollow) stood out, the area with the greatest richness, with H' = 1.596; and MS4 (bamboo grove) with H' = 1.246. The area with the lowest specific richness was the intradomicile of MS3 (EPA) (S = 3), while the lowest diversity was found in MS6 (rocky slope/ TFBR) (H' = 0.431). This low diversity is mainly due to the dominance of Ps. hirsutus hirsutus in relation to the other species collected in the area. The lowest numbers of individuals collected were recorded in the peridomicile of MS2 and in the intradomicile of MS3, with N = 5 and N = 26, respectively.

The t‐test was used to assess whether there were significant differences between the diversities of the collect points. The results indicated that there was a significant difference between the following population diversities of the stations, according to the t‐test for H′ at 5% probability: the peridomicile and the forest of MS2; the peridomiciles of MS2 and MS3; the forests of MS2 and MS3, intradomicile of MS3, peridomicile of MS3 differs from MS4 and MS5; MS4 differs from MS5; and MS6 differs from all other stations.

The results of the Moran's I for all species were not statistically significant, indicating that the limited number of sampling sites was insufficient to assess spatial autocorrelation. Despite this, notable spatial patterns emerged in species abundance distributions: Among the seven studied species, Ps. hirsutus hirsutus was the most widely distributed and abundant, followed by Ps. davisi and Ps. ayrozai, with higher abundances at MS4, and medium to low SISA values at MS2, MS3, and MS5. In contrast, the remaining species Ev. edwardsi, Mg. migonei, Ny. intermedia, and Pi. fischeri were detected at low abundances across most sites, except for Ny. intermedia, which exhibited medium abundance at MS3. All species were absent from MS1 (Figure 5).

In total, 201 specimens from five MSs were randomly selected and analysed for diagnosis of Leishmania spp. This included Br. brumpti (2) (MS5), Ny. intermedia (17) (MS3), Ps. ayrozai (6) (MS2,3,4,5), Ps. davisi (96) (MS2,3,4,5,6), Ps. hirsutus hirsutus (80) (MS2,3,4,5,6). Diagnosis of a single Ps. hirsutus hirsutus was positive for L. (V.) braziliensis in the peridomicile region (EPA, EM3), the positive sample was confirmed by hybridization with probes specific for Leishmania spp. Of this total, 25 females had visible blood residue: Ny. intermedia (1), Ps. ayrozai (3), Ps. hirsutus hirsutus (12), Ps. davisi (8) and Br. brumpti (1) were selected and analysed to determine the food sources. One specimen of Ps. davisi was diagnosed with the presence of blood from Tamandua tetradactyla (Tamanduá‐mirim) (GenBank access code: MW752259.1), collected in EM5 (TFBR). It is important to emphasize that a small sample of sandflies was analysed for both the Leishmania diagnosis and food sources.

DISCUSSION

This study, conducted in the municipality of Nova Iguaçu, in the district of Tinguá, in the EPA and TFBR areas, was scheduled to take place over 12 months, although it was interrupted in March 2020 due to the COVID‐19 pandemic. Over the course of 7 months (September 2019 to March 2020), seven collects were made, and data were obtained based on 67 samples from different MSs.

Although the survey of phlebotomine fauna was conducted over a short period, the number of species in the TFBR (forest) was close to that observed in other studies conducted over longer periods in other reserves located in the State of Rio de Janeiro (Aguiar et al., 1996; Aguiar & Soucasaux, 1984).

There was little difference in the number of species found in the EPA and TFBR. However, in the latter, as it is a more preserved forest area, species diversity tends to be higher, according to studies carried out by Arias and Freitas (1982), Ready et al. (1986) and Azevedo et al. (2008).

Psychodopygus hirsutus hirsutus was the species with the highest abundance index and was present in both areas, with indices ranging from 0.36–0.48 in the EPA and 0.42 to 0.97 in the TFBR. The species occurred in the residual forest (EPA) and forest (TFBR), as well as in the intradomicile and peridomicile areas (EPA). In the peridomicile (MS2), one specimen had L. (V.) braziliensis DNA detected. Psychodopygus hirsutus hirsutus has wild habits, but is strongly attracted to humans, as demonstrated in studies carried out in the Serra dos Órgãos National Park (Aguiar & Soucasaux, 1984). Ryan et al. (1987) found, in the same species, in the Serra de Carajás “flagellates identified as subspecies L. (V.) braziliensis subspecies”. In a study conducted by Rangel et al. (1985) in Além Paraíba, a municipality in Minas Gerais close to the border with the State of Rio de Janeiro, there was only one specimen of Ps. hirsutus hirsutus infected with Leishmania of the subgenus Viannia.

Psychodopygus davisi was the second species with the highest abundance index and also occurred in both areas, with indices ranging from 0.24–0.54 in the EPA and 0.06 to 078 in the TFBR. The species were collected in the residual forest (EPA) and forest (TFBR), as well as in the intradomicile and peridomicile areas (EPA). One specimen was found feeding on Tamandua tetradactyla in the TFBR (MS5). It is important to highlight that Tamandua tetradactyla is a possible host and reservoir of Leishmania sp. and is also important for the maintenance of transmission cycles in wild and synanthropic environments (Roque & Jansen, 2014). Studies carried out by Rotureau (2006), Lainson et al. (1981), and Mimori et al. (1989) showed that L. (V.) guyanensis was isolated from this species of anteater in Brazil and L. (Leishmania) amazonensis in Ecuador. As early as the 1970s, flagellates have been found in the digestive tract of Ps. davisi (Shaw & Lainson, 1972). The importance of Ps. davisi as a potential vector was discussed by Gil et al. (2003) in an endemic area of the State of Rondônia and by de Souza et al. (2016) in the State of Pará, where the species was predominant, highly anthropophilic and found to be infected with L. (V.) naiffi.

Nyssomyia intermedia is considered the main vector of L. (V.) braziliensis in southeastern Brazil and is widely distributed in the State of Rio de Janeiro (Andrade Filho et al., 2007). In this study, the species occurred at all three collect sites in the EPA, which confirmed its adaptation to home and peridomiciliary environments where there are domestic animals, accumulation of organic matter, and forests altered by humans (Afonso et al., 2005; Araújo Filho et al., 1981; Carvalho et al., 2014; Forattini, 1953, 1973; Forattini et al., 1976; Gomes et al., 1989; Pirmez et al., 1997; Rangel et al., 1986). It is important to note that ATL is endemic to the municipality of Nova Iguaçu, with Ny. intermedia the main species found in the areas where this disease occurs (Santana, 2003). In the Municipality of Mesquita (formerly a district of the Municipality of Nova Iguaçu) and the State of Rio de Janeiro, Rangel et al. (1990) observed a predominance of Ny. intermedia and Afonso et al. (2005) found that this species is anthropophilic in peridomiciliary environments. Epidemiological studies of potential vectors in areas where ATL occurs in Municipalities of Rio de Janeiro have shown anthropogenic changes and a higher frequency of Ny. intermedia in hot and humid months, in addition to the fact that it has already been found to be naturally infected by L. (V.) braziliensis, where the species stands out as the main vector carrying out a household cycle and is generally followed by Mg. migonei, which acts as a secondary vector during the colder and drier months (Aguiar & Soucasaux, 1984; Aguiar & Vilela, 1987; Aragão, 1922, 1927; Azevedo et al., 2015; Rangel et al., 1990; Sabroza et al., 1975). The absence of Ny. intermedia in the forest environment may suggest that transmission by this sand fly species occurs in the domestic environment.

Psychodopygus ayrozai is an anthropophilic species found in the mountainous regions of southeastern Brazil and is more frequent during hot and humid months (Aguiar & Soucasaux, 1984). In the present study, Ps. ayrozai was found in the residual forest (MS3) and inside the reserves (MS4 and MS5) between December and February, leading to this species having the highest abundance index in MS4. This species has been identified as a vector for L. (V.) naiffi in the State of Pará (Lainson & Shaw, 1998; Rangel & Lainson, 2009), although it is not an anthropophilic phlebotomine species in the Amazon region (Lainson & Shaw, 1998; Rangel & Lainson, 2009). Specimens of this phlebotomine have also been found in L. (V.) naiffi in the States of Amapá and Rondonia (Arias et al., 1985; de Souza et al., 2016). In the Cerrado (state of Tocantins), the species was naturally infected with L. (V.) braziliensis, although the frequency was low and the authors suggested that Ps. ayrozai may play a secondary role in local epidemiology (Vilela et al., 2013).

Pintomyia fischeri occurs both in forest areas and in the domestic environment, where it occurs in domestic animal shelters (Aguiar et al., 1989; Moschin et al., 2013; Vieira et al., 2015, 2022). The species is identified as a secondary vector of L. braziliensis and suspected as Leishmania (Leishmania) infantum in the metropolitan region of São Paulo and in Porta Alegre, in Rio Grande do Sul (Galvis‐Ovallos et al., 2020; Rêgo et al., 2020). In the current study, this species occurred with a low abundance index in the chicken coop (MS2) and MS4 at 1578 m from MS2. Aguiar et al. (1989) and Vieira et al. (Vieira et al., 2015; Vieira et al., 2022) highlighted that, Pi. fischeri was the species with the greatest dispersion, as they observed, based on the ratio of collected females and males, that the species probably maintains its breeding grounds in the forest; however, they appear in the anthropic environment for hematophagy, while Ny. intermedia and Mg. migonei could be the species most adapted to the peridomiciliary environment. Vieira et al. (2022) in a study in the State of Rio de Janeiro showed the presence of the species at three collecting sites (home, peridomicile, and forest). However, the distance between the forest and the anthropogenic area, around 300 m, suggested that it was the species with the greatest dispersal and that it could be participating as a maintainer of the wild and home cycles, due to the small number of males collected in the home and peridomicile and the high number of males in the forest. Lainson (1983) suggested that this species could be an example of a phlebotomine that has adapted to environmental changes caused by human activity, maintaining the ability to transmit L. (V.) braziliensis among wild animals in the remnants of secondary forests that are still preserved. Barretto (1943) recorded the occurrence of this species in 41 municipalities in the State of São Paulo and hypothesized that it adapted from the wild to the home environment.

Evandromyia edwardsi is associated with cave environments, rock formations, forests, and wild animal shelters (Capucci et al., 2023; Castellon et al., 1995). The species had a positivity rate of 7.1% in the research carried out by Capucci et al. (2023) with the application of the PCR technique directed at the ITS1 target to detect Leishmania DNA. Sucen (2005) and Serra e Meira et al. (2022), found the species infected with L. braziliensis and also mentioned the presence of DNA from L. amazonensis and L. infantum. No caves were observed close to the MSs in our study area; however, the region has several rock formations and a large number of wild animal burrows. These may be the factors determining the occurrence of Ev. edwardsi, even with a low abundance rate, or other species of sand flies with wild habitats.

Migonemyia migonei is a wild species, preferably found in areas with abundant vegetation, although it can occur in domestic animal shelters and less frequently in secondary forests and capoeiras (Araújo Filho et al., 1981; Rangel et al., 1986; Rangel et al., 2018). In the present study, this species was not observed in the peridomicile (animal shelter) or the residual forest of the EPA. In this study, the species occurred in MS5 and MS6 with low abundance levels at altitudes of 399 and 424 m, respectively. Aguiar et al. (1993) and Aguiar et al. (1996) in studies carried out in the municipality of Itaguaí (Serra do Mar), state of Rio de Janeiro, observed the predominance of Mg. migonei in drier areas without banana plantations at an altitude of 300 m. The occurrence of this species in domestic animal shelters was also not observed, perhaps because our collections were carried out during the hot and rainy seasons. Migonemyia migonei has been found naturally infected by flagellates in the State of São Paulo (Pessoa & Coutinho, 1941; Pessoa & Pestana, 1940) and also by L. (V.) braziliensis in the Municipality of Baturité, State of Ceará (Azevedo et al., 1990; de Queiroz et al., 1991) and in the State of Rio de Janeiro (Ilha Grande and Jacarepagua) (Carvalho et al., 2014; Gouveia et al., 2012; Pita‐Pereira et al., 2005; Rangel & Lainson, 2009). The species was also associated with American Visceral Leishmaniasis when studies used molecular techniques (PCR) to identify infection by L. (L.) infantum chagasi in the states of Pernambuco and Ceará (Carvalho et al., 2010; Rodrigues et al., 2016).

CONCLUSION

Finally, it is important to highlight the presence in the region of primary vectors, potential vectors, L. (V.) braziliensis and a natural reservoir in the APA and REBIO, drawing attention to the probability of a transmission cycle that could be both wild and domestic for ATL. The studied area has very few studies in the literature and the data obtained are of great importance for referencing and guiding managers of entomological and epidemiological surveillance on the importance of reinforcing and intensifying measures for the prevention and control of the disease, aiming at the protection of the resident population and tourists who visit the region.
