“…In the current study, the species richness recorded in the peridomiciliary environment (i.e., the least conserved area) of the NMPC was in accordance with those of previous observations in the peridomiciliary environment of the Atlantic Forest, State of Espṍrito Santo (Pinto et al 2010a(Pinto et al , 2012aVirgens et al 2008). However, when we included in our analyses, specimens captured in the forested environment (i.e., the most conserved area) of the NMPC, the species richness increased signiÞcantly.…”

We evaluated the ecological and epidemiological aspects of the sand fly fauna in an area of the Atlantic Forest biome with records of visceral and cutaneous leishmaniasis. Sand fly collections at three different localities at the National Monument of Pontões Capixabas, State of Espírito Santo, Southeastern Brazil, were conducted by using two Centers of Disease Control and Prevention automatic light traps in the peridomiciliary environment and eight Centers of Disease Control and Prevention automatic light traps in the forested environment. Collections occurred during four consecutive nights within each of the months and locations: São Luiz (December 2009, May 2010, July 2010, and December 2010), Córrego Palmital de Baixo (September 2010 and October 2010), and Córrego São Bento (February 2011 and May 2011). We collected 21,138 sand flies belonging to 31 species and 14 genera. Of this total, 12,412 sand flies were captured in the peridomiciliary environment and 8,726 in the forested environment. All of the vector species, Lutzomyia longipalpis (=Lutzomyia longipalpis, sensu; Young and Duncan), Migonemyia migonei (=Lutzomyia migonei, sensu; Young and Duncan), and Nyssomyia intermedia (=Lutzomyia intermedia, sensu; Young and Duncan), occurred in significantly higher numbers in the peridomiciliary environment than compared with the forested environment. Our results highlight the importance of conservation in the forest remains of the National Monument of Pontões Capixabas, because of higher species richness and diversity. Furthermore, they indicate the epidemiological role of Lu. longipalpis as the vector of Leishmania infantum within the study area, and the no evident role of Mg. migonei.

“…To establish the similarity among conservation units within the state of Espírito Santo, we used eight conservation areas as Operational Geographic Units (OGUs) (Crovello ) and sand fly species records were used as characters (Table ). The sand fly distribution data for the conservation units were compiled from Virgens et al (), Pinto et al (,), Pinto et al (,), Ferreira et al (), and Núcleo de Entomologia da Secretaria do Estado da Saúde do Espírito Santo (unpublished data). The conservation units can be grouped into three kinds using the elevation as a classification criterion: 1) highland conservation units (830 m a.s.l.])…”

“…The phlebotomine sand flies (Diptera: Psychodidae) are the main leishmaniasis vectors along the Brazilian states situated on the Atlantic coast, such as the state of Espírito Santo. Historically, almost all the studies of sand fly fauna in this state were conducted in disturbed areas of endemic leishmaniasis regions as a result of the medical and veterinary importance of these flies (Barros et al , Ferreira et al , Pinto et al , Pinto et al ). Only recently, some studies were conducted in conservation units next to leishmaniasis endemic (Pinto et al ) or non‐endemic (Pinto et al ) areas.…”

Most studies of the sand fly fauna in southeastern Brazil are conducted in the peridomiciliary environment of leishmaniasis endemic regions. Therefore, to increase the knowledge about diversity and richness of sand fly conservation areas, we describe here the sand fly fauna from the National Forest of Goytacazes (NFG), state of Espírito Santo, Brazil, and its surroundings areas. We also used sand fly fauna records from eight conservations units within the state of Espírito Santo to understand the similarity and relationships among them. The sand flies were simultaneously collected from June, 2008 to May, 2009 in two different environments: a preserved environment represented by the NFG and a modified environment represented by a peridomicile. To establish the similarity among the conservation units, we used a method very similar to parsimony analysis of endemism. We collected 2,466 sand fly specimens belonging to 13 species. Pressatia choti and Nyssomyia intermedia were the most abundant sand fly species. Ny. intermedia is a known vector of Leishmania braziliensis and epidemiological surveillance must be conducted in the area. We discuss aspects regarding the diversity of sand flies as well as the risk of transmission of Leishmania parasites in the area. We also provide for the first time a hypothesis of similarity relationships among conservation units within the state of Espírito Santo. Journal of Vector Ecology 40 (1): 28-35. 2015.

“…Among other animals, chickens live in close contact with man and are attractive food sources for sandflies in Teresina. In this city, it is common practice to raise chickens 27,28,32,59 . Therefore, the connection between the domestic and sylvatic cycle of disease transmission may be facilitated by these farm birds.…”

SUMMARYVisceral leishmaniasis (VL) has been known to occur in the state of Piauí since 1934. The typically rural disease began to appear in urban areas over time, being concentrated mainly in Teresina, the capital of Piauí. Teresina was also affected by the first urban epidemic of VL in Brazil. Over 1,000 cases of the disease were reported during urbanization (1981)(1982)(1983)(1984)(1985)(1986)). Human population growth and migration led to land occupation on the outskirts of Teresina. These factors have contributed to vector proliferation, increasing the incidence of VL. At present, the incidence of human and canine disease is quite high and uncontrolled in Piauí. It seems that some measures, such as the elimination of seropositive dogs, failed to significantly reduce the number of new VL cases in Teresina. Despite previously conducted studies, little is known about VL epidemiology in urban areas. The aim of this review is to reveal the situation of VL in Teresina during the last 40 years, focusing on the major factors that may contribute to the high incidence and persistence of VL infection.
