“…One‐third of the species were found exclusively in the short‐term area. Richness was high in the conserved forest fragment, comparable to that found in the dense rainforest (Marinho et al 2008, Rebêlo et al 2019) and open (Campos et al 2013, Moraes et al 2015), being almost two times greater than in the degraded forest and quite different from the anthropogenic environment. Nine species were absent in both the peri‐domicile or the intra‐domicile environments of the short‐term area.…”

“…In this case, backyards can be the breeding grounds for some of these species, at least the most abundant. Shelters installed without the necessary hygiene and protection are important factors that justify the greater abundance of sand flies in the backyards of houses (Pereira‐Filho et al 2015, Bandeira et al 2017). In these shelters, sand flies were found containing the blood of domestic animals, including dogs, pigs, horses, chickens, and synanthropic rodents and marsupials (Dias et al 2003, Oliveira‐Pereira et al 2008, Fonteles et al 2009, Guimarães‐e‐Silva et al 2017, Pereira‐Filho et al 2018, Fonteles et al 2018).…”

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.

“…Studies carried out in the state of Maranhão have shown that altered primary forest areas [3,5,19,20] and even secondary forests in metropolitan areas [21], contribute immensely to the greater local diversity of sandflies. In these environments, a large number of species with different degrees of abundance normally occur.…”

O presente estudo analisa a variação na riqueza e abundância de flebotomíneos em assentamentos rurais, com diferentes graus de degradação florestal, na Amazônia do Estado do Maranhão. Os flebotomíneos foram capturados nos municípios de Santa Luzia (área moderadamente degradada), Senador La Rocque (muito degradada) e Governador Nunes Freire (completamente degradada), durante três noites consecutivas, uma vez por mês, de maio/2012 a abril/2014. No computo geral, foram capturados 6.810 espécimes de 35 espécies de flebotomíneos, distribuídas em 13 gêneros. O mais diversificado foi Evandromyia (9 espécies), seguido por Psathyromyia (5), Pressatia (3) e Psychodopygus (3). As espécies mais abundantes foram Nyssomyia whitmani (32,33%), Evandromyia evandroi (14,89%), Lutzomyia longipalpis (12,45%), Brumptomyia avellari (6,73%), Pintomyia damascenoi (6,59%) e Migonemyia migonei (6,46%). Em todas as áreas a riqueza de espécies foi maior nos fragmentos florestais do que nos peridomicílios rurais, exceto naquela, cujo fragmento florestal estava muito degradado. A abundância de indivíduos foi maior em todos os peridomicílios. A degradação crescente da cobertura vegetal natural vem reduzindo as florestas e a riqueza de espécies de flebotomíneos. Entretanto, os fragmentos de florestas secundárias remanescentes ainda mantêm um número considerável de espécies, as quais frequentam em maior ou menor grau os assentamentos rurais adjacentes. Esses novos ambientes oferecem aos flebotomíneos oportunidades (abrigos e fontes de alimento) necessárias para a reprodução e proliferação. Como consequência, as leishmanioses passam a mudar o seu perfil epidemiológico, incidindo nas populações humanas suscetíveis.
