Abstract
Leishmaniasis is a group of diseases caused by protozoa of the genus Leishmania and is transmitted by the bite female sand fly. The present work is characterized as a descriptive study in two areas: a forest area located in the Parque Estadual do Rio Doce, and another urban area located in the municipality of Timóteo-MG, with the objective of identifying the presence of Leishmania spp. and the blood source of the collected female sand flies. Part of the females were obtained from the Parque Estadual do Rio Doce, and part was collected using 19 ligth traps distributed in residences of Timóteo. For molecular studies of Leishmania spp. DNA, the ITS1 gene was used, and in the search for blood source, the CytB gene was used and positive samples were sequenced. The study demonstrated that there are at least three species of Leishmania circulating in the study areas: Leishmania (Viannia) braziliensis, Leishmania (Leishmania) amazonensis, and Leishmania (V.) guyanensis. Nyssomyia whitmani was the predominant sand fly species in the urban area of Timóteo with a positive diagnosis for the presence of Leishmania braziliensis DNA. We found the presence of blood from Gallus gallus (Chicken) and Sus scrofa (Pig) in sand flies. The present study demonstrates that Leishmania braziliensis is the main agent of cutaneous leishmaniasis in the study area, with the effective participation of Nyssomyia whitmani as the vector and both Gallus gallus and Sus scrofa acting as a food source for female sand flies, and helping maintaining the sand fly life.

Abstract
Phlebotomines (Diptera: Psychodidae) are vectors of protozoa of the genus Leishmania and distributed throughout Brazil, formerly restricted to rural areas, have expanded including to periurban and urban regions, been recorded in different habitats. This study aimed to understand the dynamics of sand flies in different ecotopes in the municipality of Pains. Sand flies were captured during thirty samplings using HP light traps installed in seven different ecotopes for two consecutive nights, once a month, from August 2018 to July 2019. A total of 1,352 sand flies were captured, representing 24 species belong to ten genera. Evandromyia edwardsi was the most abundant species, followed by Evandromyia lenti and Micropygomyia quinquefer. Leishmania DNA was detected in seven female sand flies in four ecotopes, for an infection rate of 0.9%. Sand flies were collected in all seven ecotopes, although forest (23.04%), cave (20.88%) and pasture (17.75%) had higher abundance and richness. Similarity was found among ecotopes, indicating that they are all important for the maintenance of the sand fly community. Spatial analysis indicated high densities of sand flies in areas with natural characteristics. All ecotopes in the municipality were evidenced to have an adequate and harmonious epidemiological profile for the transmission and expansion of leishmaniasis throughout the territory. Because of the increasing environmental changes and deforestation in the municipality, the risk of generating ecological imbalance and increased cases of leishmaniasis is imminent, which highlights the importance of developing preventive and control strategies.

Abstract
Background: The present study was carried out in the rural and urban area of Diamantina/Minas Gerais (MG), an endemic municipality for visceral leishmaniasis (VL) in Brazil. Methods: Patient notification records, canine prevalence, and phlebotomine fauna were evaluated. Results: In the period from 2016 to 2018, eight human cases were confirmed, with three deaths, predominantly in males. In the same period, a total of 1,388 dogs resided in the rural and urban area of the municipality were submitted to the DPP® and ELISA, with a percentage of confirmed canine cases of 29.9% and 29.4%, respectively. The entomological study conducted in the municipality revealed the presence of 10 species of sand flies, with a predominance of Lutzomyia longipalpis (55.75%), mainly in the rural area. Conclusions: Unlike what is happening in urban centers, the results of this study suggest that the VL in Diamantina is in the process of urbanization, given the high percentage of confirmed canine cases and the high density of Lu. longipalpis in the rural area of the municipality. These risk factors warn about the need for continuous surveillance and the need to control actions of VL in this area.

Abstract
BACKGROUND Leishmaniasis is a rapidly expanding zoonosis that shows increasing urbanization. Concern exists regarding the role of wildlife in visceral leishmaniasis (VL) transmission, due to frequent natural or anthropogenic environmental changes that facilitate contact between wildlife, humans and their pets. The municipality of Campinas, in southeastern Brazil, initially recorded VL in 2009, when the first autochthonous case was confirmed in a dog living in an upscale residential condominium, located inside an environmentally protected area (EPA). Since then, disease transmission remains restricted to dogs inhabiting two geographically contiguous condominiums within the EPA. METHODOLOGY/PRINCIPAL FINDINGS We conducted a cross-sectional study of the VL focus to investigate Leishmania spp. infection in domestic dogs, wild mammals and sand flies using molecular tools and recommended serological techniques. Canine seroprevalences of 1.5% and 1.2% were observed in 2013 and 2015, respectively. Six insect species, confirmed or suspected vectors or potential transmitters of Leishmania, were identified. Two specimens of the main L. (L.) infantum vector in Brazil, Lutzomyia longipalpis, were captured in the EPA. Natural infection by L. (L.) infantum was recorded in one Expapillata firmatoi specimen and two Pintomyia monticola. Natural infection by L. (L.) infantum and Leishmania subgenus Viannia was also detected in two white-eared opossums (Didelphis albiventris), a known reservoir of VL. Geographical coordinates of each sampling of infected animals were plotted on a map of the EPA, demonstrating proximity between these animals, human residences, including the dogs positive for VL, and forest areas. CONCLUSIONS/SIGNIFICANCE The EPA, which is inhabited by humans, has an active VL focus. The risk of establishing and maintaining disease transmission foci in similar scenarios, i.e. wild areas that undergo environmental modifications, is evident. Moreover, different epidemiological profiles of VL must be included to elaborate prevention and control measures that consider the particularities of each transmission area.

Abstract
The Aquidauana municipality is considered an endemic area of leishmaniasis and an important tourist site in Mato Grosso do Sul State. The aim of this study was to investigate the sand fly fauna in the city of Aquidauana. Captures were carried out twice a month, from April 2012 to March 2014 with automatic light traps and active aspiration, in the peridomicile and domicile of six residences. A total of 9,338 specimens were collected, 3,179 and 6,159 using light traps and active aspiration, respectively. The fauna consisted of: Brumptomyia brumpti, Evandromyia aldafalcaoae, Ev. evandroi, Ev. lenti, Ev. orcyi, Ev. sallesi, Ev. termitophila, Ev. walkeri, Lutzomyia longipalpis and Psathyromyia bigeniculata. The most abundant species captured was Lutzomyia longipalpis, present in all the ecotopes, predominantly in peridomicile areas, and mainly males. Leishmania DNA was not detected in the insects. It was observed the abundance of the sand fly fauna in the region, as well as the high frequency of Lu. longipalpis, the main vector of L. infantum. The results of this study show the need to increase the monitoring and more effective control measures. It is noteworthy that the studied region presents several activities related to tourism and recreation, increasing the risk of transmission of leishmaniasis to this particular human population.

Abstract
In the New World, the leishmaniases are primarily transmitted to humans through the bites of Leishmania-infected Lutzomyia (Diptera: Psychodidae) phlebotomine sand flies. Any or both of two basic clinical forms of these diseases are endemic to several cities in Brazil—the American cutaneous leishmaniasis (ACL) and the American visceral leishmaniasis (AVL). The present study was conducted in the urban area of a small-sized Brazilian municipality (Jaboticatubas), in which three cases of AVL and nine of ACL have been reported in the last five years. Jaboticatubas is an important tourism hub, as it includes a major part of the Serra do Cipó National Park. Currently, no local data is available on the entomological fauna or circulating Leishmania. During the one-year period of this study, we captured 3,104 phlebotomine sand flies belonging to sixteen Lutzomyia species. In addition to identifying incriminated or suspected vectors of ACL with DNA of the etiological agent of AVL and vice versa, we also detected Leishmania DNA in unexpected Lutzomyia species. The expressive presence of vectors and natural Leishmania infection indicates favorable conditions for the spreading of leishmaniases in the vicinity of the Serra do Cipó National Park.

Abstract
This work is characterized by an entomological research and an investigation on whether seasonal behaviours can be associated to the phlebotomine fauna found in the urban area of Timóteo-MG - an endemic focus of tegumentary leishmaniasis (TL). The analysis of the seasonal behaviour of sand flies has taken into account the following climatic variables: rainfall, relative humidity and temperature. Automatic light traps were installed in households between 2009 and 2010. The sand fly species with the highest number captured was Lutzomyia whitmani (66.5%), a TL vector species, whose abundance has provided strong evidences that this species is the main vector of TL in the municipality of Timóteo, with its cycle of transmission developing in its urban area. Amongst the results observed in the analyses of seasonal behaviour, only temperature conveyed particular association between seasonal occurrence of sand flies and climate variables. The findings of this study may assist the local epidemiological surveillance agency in defining strategies and directing efforts for controlling these insects.

Abstract
Background Sand fly collections were performed to study ecological aspects of the Phlebotominae fauna of the Xakriabá Indigenous Reserve, an area with endemic cutaneous leishmaniasis, located in the state of Minas Gerais, Brazil. Methods The collections were performed in peridomicile areas and along trails previously selected for the study of wild and synanthropic Leishmania hosts. Differences in the distribution patterns of the sand fly species as well as in species richness and abundance between the different ecotopes were investigated during both rainy and dry seasons over the course of the study period. Results A total of 8,046 sand flies belonging to 11 genera and 28 species were collected. Lutzomyia longipalpis and Nyssomyia intermedia were the most abundant species in peridomicile areas, whereas Martinsmyia minasensis and Lutzomyia cavernicola were the most abundant species among the different trail ecotopes. Conclusion The different composition of the sand fly fauna observed in the peridomicile areas and in the trails during the study, reinforces the importance of sampled different areas in a phlebotomine fauna survey. The presence of Lutzomyia longipalpis and Ny. Intermedia most abundant in peridomicile can be important to Leishmania infantum and Leishmania braziliensis transmission in the Imbaúbas native village.

Abstract
The aim of this study was to evaluate the sand fly fauna of American visceral leishmaniasis (AVL) endemic areas within the Central Atlantic Forest Biodiversity Corridor, State of Espírito Santo, southeastern Brazil. The sand fly captures were performed between January, 1989 and December, 2003 in localities where autochthonous cases of AVL were recorded, as well as in their boundary areas. Sand flies were collected from surrounding houses and domestic animal shelters using two to five CDC automatic light traps, and manual captures were also performed using mouth aspirators in one illuminated Shannon trap during the first four hours of the night. We used cladistic analysis to determine the geographic relationships among the collected sand fly species as well as the index species for the occurrence of other sand flies. A total of 62,469 sand flies belonging to 17 species and eight genera was collected in 164 localities from nine municipalities with AVL records. The richness (S=17) and diversity (H=0.971) of sand flies were lower than in conservation areas and similar to modified environments in the Atlantic Forest of Espírito Santo. Lutzomyia longipalpis was identified in 79 localities. The cladistic analysis identified Evandromyia lenti as the index species for Lutzomyia longipalpis. The latter seems to be the main vector of AVL in the Central Atlantic Forest Biodiversity Corridor due to its high abundance and distribution matching the disease occurrence. Therefore, Evandromyia lenti may be used as an index species for the occurrence of Lutzomyia longipalpis.

Abstract
Nyssomyia intermedia (Lutz & Neiva 1912) and N. neivai (Pinto 1926) are possible vectors of tegumentary leishmaniasis in some regions of Brazil. Further, the latter was until recently, considered a junior synonym of the former. This study has the purpose of updating our knowledge of the geographical distribution of these species, based on specimens deposited at the collection of the Centro de Pesquisas René Rachou-Fiocruz, Faculdade de Saúde Pública-Universidade de São Paulo, and on data presented by literature as also to associate this distribution with the cutaneous leishmaniasis cases reported. It has been reported that N. intermedia occurs in the states of the Northeastern Region, in Rio de Janeiro, Espírito Santo, on the northern coast of São Paulo, in eastern Minas Gerais, Mato Grosso do Sul, and Goiás, close to the border with Minas Gerais and Bahia. N. neivai occurs in the Southern Region, southern coast and in western São Paulo, southern and western Minas Gerais, southern Goiás, and southern Pará, beyond Argentina, Bolivia, and Paraguay. It is important to highlight that N. intermedia and N. neivai occur in sympatry in Minas Gerais and São Paulo. N. intermedia or N. neivai are predominant or are captured abundantly in several cutaneous leishmaniasis foci in the Southeastern and Southern regions of Brazil.

Na localidade do Brejo do Mutambal, situado no município de Varzelândia (MG), área endêmica para leishmaniose tegumentar, foram realizadas capturas mensais sistemáticas utilizando-se armadilhas luminosas do tipo CDC durante o período de janeiro a dezembro de 2000. Foram capturadas 19 espécies de flebotomíneos, totalizando 6.756 exemplares. Lutzomyia intermedia (5,1%), L. migonei (0,4%) e L. whitmani (0,1%), relacionadas com a transmissão de leishmaniose tegumentar, foram capturadas em número reduzido. Lutzomyia longipalpis foi a espécie predominante (34,8%), sugerindo também um risco de transmissão da leishmaniose visceral. A proporção de insetos capturados no peridomícilio foi de 91,7% enquanto no intradomicílio foi de 8,3%. A interferência de fatores climáticos (temperatura, umidade relativa do ar e pluviosidade) sobre a dinâmica populacional de flebotomíneos foi avaliada.

Abstract
In the period from November of 2000 to November of 2001, a study of sand flies was realized in the municipalities of Alto Caparaó and Caparaó with the objective of determining their seasonal variation, comparing the points of study related to the occurrence of these insects and detecting their ideal environments. Monthly collections were carried out, with Falcão light traps at nine points, four traps per point, in the following environments: of animals shelter, forest (bush), coffee plantation and the external walls of houses. Lutzomyia intermedia (Lutz & Neiva, 1912) was the predominant species, and animal shelter the environment with the largest occurrence of sand flies. A significant difference in the composition of sand fly species was found in the studied points. Lutzomyia intermedia is the species suspected of transmitting Leishmania in the region.

Abstract
A study of the phlebotomine sand fly fauna was carried out in an endemic area of American visceral leishmaniasis (AVL) in the municipality of Porteirinha, in the Brazilian state of Minas Gerais. Captures were performed with CDC light traps in 7 districts, 5 days per month, during 2 consecutive years (January 2000 to December 2001). A total of 3240 sand flies were captured and identified. Sixteen species were found, among which 15 belonged to the genus Lutzomyia and one to the genus Brumptomyia. Lutzomyia longipalpis, a proven vector of AVL, was the predominant species (71.85%) throughout the time period. The interference of climatic factors (temperature, humidity, and rainfall) over the populational dynamics of the sand flies was determined. Statistical analysis of the data showed a significant correlation among the number of phlebotomine sand flies collected, rainfall, and humidity, whereas the effect of temperature was negligible, in that particular region. The amount of collected phlebotomine, the number of human cases, and the prevalence of canine AVL in the districts of Porteirinha are discussed.

Abstract
In 1997, 1998 and 1999 we performed several captures in the State of Piauí, in the counties of Barro Duro, Campo Maior, Castelo, Floriano, Picos, São Raimundo Nonato and Teresina. We used CDC light traps inside houses, in a primary forest and in one cave. Seventeen species were collected being Lutzomyia longipalpis, Lutzomyia samueli, Lutzomyia whitmani and Lutzomyia lenti the most captured species. The genus Brumptomyia, L. whitmani, Lutzomyia sordellii, Lutzomyia carmelinoi, Lutzomyia termitophila, Lutzomyia peresi and Lutzomyia quinquefer are reported for first time in Piauí. We call the attention for the presence of L. whitmani and L. longipalpis, important vectors of leishmaniasis in various regions of South America.

Abstract
The family Psychodidae includes the medically important phlebotomine sand flies and four other subfamilies that have been little studied in the Neotropics. The authors here report the results of a trip to collect psychodids in Parque Estadual do Rio Doce, a national park in Minas Gerais that contains one of the largest surviving areas of Atlantic Forest in Brazil. Collections made by Malaise and CDC light traps as well as from diurnal resting sites included 15 species of Psychodinae and Trichomyiinae, among them Trichomyia dolichopogon sp. nov., T. riodocensis sp. nov. and 13 other species new to science but represented by females only. Twelve species of phlebotomine sand flies (Lutzomyia spp.) were also collected. Collections from an undisturbed area of the park were much richer faunistically than those from an area that was destroyed by fire in 1967 but had since regenerated, suggesting that recovery after environmental disturbances of this type may be prolonged. This pattern was not seen for phlebotomine sand flies, whose greater abundance and species richness in the disturbed section of the park may be related to their dependence on small mammal hosts, known to be more diverse in this type of habitat.

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.
