“…Animal shelters help to attract both male and female sand flies. While females frequent them for blood meals (Dias et al 2003, Oliveira‐Pereira et al 2008, Fonteles et al 2009), males seek females for copulation. In this case, backyards can be the breeding grounds for some of these species, at least the most abundant.…”

The richness and abundance of sand fly species were studied in northeastern Brazil in areas of leishmaniasis transmission. The study was carried out in two forest areas with different deforestation times for agricultural and livestock activities: one modified by long‐term settlement (more than 50 years of occupation) and another less impacted by short‐term settlement (10 years). The sand flies were captured with CDC light traps from 18:00 to 06:00 for three consecutive nights, once a month, from May, 2012 to April, 2014. The study captured 21,708 specimens and also 33 species of Lutzomyia and two of Brumptomyia. Species richness and abundance were higher in the more conserved area of short‐term occupation (31 species; 61.7%) than in the more degraded area with long‐term occupation (17 species; 38.3%). In the most conserved area, the species richness was higher in the forest fragment than in the rural settlement, whereas in the degraded area the richness was higher in the peri‐domicile than in the forest. The diversity was higher in the degraded area forest. There were significant statistical differences when comparing the means of total abundance with the intra‐domicile, peri‐domicile, and forest environments. The average abundance was statistically higher in the peri‐domicile compared to the forest (p = 0.009), but there were no statistically significant differences between intra‐domicile‐peri‐domicile (p = 0.11) and forest‐intra‐domicile (p = 0.87). In conclusion, a change in vegetation cover negatively affects the richness and abundance of sand flies in the natural environment.

“…Apresentaram alta capacidade de picar com avidez mamíferos de porte variado e aves, corroborando as observações de Costa et al (2013), obtidas na região dos Lençois Maranhenses. Tal comportamento é comum entre insetos nematóceros hematófagos, incluindo os lebotomíneos que foram estudados neste aspecto, também na ilha de São Luís (DIAS et al, 2003) e no interior do estado do Maranhão (OLIVEIRA-PEREIRA et al, 2008;FONTELES et al, 2009). …”

Submetido em 11/03/2014 Aceito para publicação em 15/12/2014 Resumo O conteúdo estomacal de fêmeas do gênero Culicoides foi estudado para determinar suas fontes alimentares sanguíneas e o grau de relações estabelecidas entre esses insetos e seus hospedeiros. Os espécimes foram capturados em armadilhas luminosas tipo CDC no período entre março de 2009 e fevereiro de 2010, em duas localidades rurais da ilha de São Luís-MA. Foram capturadas 930 fêmeas ingurgitadas, pertencentes a 12 espécies de Culicoides. Foi utilizado o exame da reação da precipitina, que revelou o sangue de sete tipos diferentes de vertebrados que haviam sido sugados, sendo os mais frequentes: ave (41,9%), roedor (21,2%), cão (15,4%) e ser humano (7,3%). Nas reações duplas predominaram ave/cão (20%) e cão/gato, cão/gambá, ave/roedor, gambá/roedor e gato/humano (13,3% cada). Dentre as espécies de Culicoides encontradas, C. paucienfuscatus Barbosa, 1947 destacou-se, por ter sugado apenas sangue de aves. As 11 espécies restantes sugaram sangue tanto de animais domésticos como de sinantrópicos, sendo que, destas, quatro também sugaram o sangue humano. Os resultados permitiram concluir que C. paucienfuscatus apresentou relações especíicas, foi considerada ornitóila e as outras espécies foram generalistas. A presença desses animais em ambiente peridoméstico é um fator que favorece a manutenção dos Culicoides nos povoados rurais e a presença do ser humano como um dos vertebrados mais sugados indica que além de fazer parte da dieta das fêmeas de Culicoides, pode participar de eventuais ciclos epidemiológicos de parasitas, devido ao hábito eclético desses insetos.

“…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.…”

Forty years of visceral leishmaniasis in the State of Piaui: a review

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.
