“…Similar findings were obtained in previous studies in Brazil and Panama [ 19 , 21 ]. The microhabitat characteristics that are suitable for development of immatures of genus Lutzomyia and Brumptomyia seem to include an abundance of organic material derived from animal faeces, decomposing leaves and fruit, as well as structures such as trees with protected spaces that provide refuge from rain, wind, strong light and predators [ 19 - 21 , 42 ].…”

BackgroundThe location of the microhabitats where immature phlebotomine sand flies of the genus Lutzomyia develop is one of the least-known aspects of this group of medically important insects. For this reason strategies of source reduction approach for their control have not been possible in contrast to other insect vectors (such as mosquitoes), because their juvenile stages in terrestrial microhabitats is difficult to detect.MethodsDirect examination of soil samples, incubation of substrates and the use of emergence traps were the methods used to identify juvenile stages in 160 soil samples from urban and forest habitats within the foci of Leishmania transmission in Colombia. Immatures collected were identified subsequent from the rearing and emergence of adults using taxonomic keys or the analysis of the mitochondrial marker cytochrome oxidase I. Plant species associated with the natural breeding sites were identified and physicochemical properties of the soils were analyzed.ResultsA total of 38 (23.7%) sampling sites were identified as breeding sites, 142 phlebotomine sand flies were identified, belonging to 13 species of the genus Lutzomyia and two of Brumptomyia. The greatest numbers of immature were found within the tabular roots (51 immature sand flies from eight positive sites) and bases of trees (35 immature sand flies from 11 sites). The characterization and presence of the tree species (mainly Ceiba pentadra, Anacardium excelsum, Pseudosamanea guachapale) and the physicochemical properties (relative humidity and carbon/nitrogen ratio) of the soils associated with these breeding sites are significant factors in explaining the diversity and abundance of phlebotomine sand flies.ConclusionsImmature phlebotomine sand flies of the genus Lutzomyia in Colombia can be found in a wide variety of breeding sites rich in organic matter, high relative humidity and are associated with a typical vegetation of each locality. These results provide new perspectives for the study of the ecology of the genus Lutzomyia in Colombia and the development of vector control strategies.

“…This Þnding may be because of the alterations in the forest environments that have restricted the ecological spaces for phlebotomines, which forces these species to seek protection in peridomiciliary and intradomiciliary environments (Feitosa and Castellon 2004).…”

Ecology of Phlebotomines (Diptera: Psychodidae) in a Transitional Area Between the Amazon and the Cerrado in the State of Maranhão, Brazil

“…A tendência dos flebotomíneos de invadirem o ambiente antrópico, tem sido constatada em áreas das regiões Norte (Feitosa & Castellón 2004), devido a alterações de floresta, que provocaram a restrição de espaços ecológicos. Considerando a importância dos flebotomíneos e a localização da RFS e RFI nas proximidades da área metropolitana de São Luís, é aconselhável manter contínua vigilância na zona de entorno das referidas reservas.…”

Os flebotomíneos são naturalmente diversificados nas florestas tropicais úmidas (Ward et al. 1973, mas muitas espécies vêm invadindo os ambientes peridomiciliares de zonas rurais e urbanas em diversas áreas endêmicas para leishmanioses no Brasil. A capacidade de freqüentar ambientes artificiais e a ocorrência em alta densidade são condições que incriminam os flebotomíneos como vetores das leishmanioses (Gomes & Galati 1989).No Estado do Maranhão, são conhecidas mais de 30 espécies de flebotomíneos que se associam com áreas florestais (Rebêlo et al. 2000a, b) ABSTRACT. Phlebotomines (Diptera, Psychodidae) in forest reserves in the metropolitan area of São Luís, Maranhão, Brazil. This study deals with the diversity, relative abundance and seasonality of sandflies species in two modified primary forest fragments, situated at São Luís city, capital of the state of Maranhão. The sandflies were captured with the use of light traps, CDC (Center Control Disease) type, installed at the edge and in the center of the forest, at the height of 1.5 meter, being there from 6 p.m. up to 6 a.m., once per month, during a year time. An amount of 1,356 specimens from 23 species, which 21 belonged to genera Lutzomyia and two belonged to genera Brumptomyia, were captured. In the Sacavém forest reserve, 1,061 specimens were captured, resulting in a capture effort of 2.5 individuals/ hour/trap, most of them L. longipalpis (44.8%), followed by L. antunesi (36.4%), L. sordelli (5.9%), L. flaviscutellata (3.9%) and L. whitmani (2.1%). The highest concentrations of species (11) and individuals (60.1%) occurred during the rainy period. In the Itaqui forest reserve, 295 specimens were collected and the capture effort was 0.2 individuals/hour/ trap, most of them were L. flaviscutellata, (58.6%), L. sordelli (14.6%), L. longipalpis (7.1%), L. evandroi (6.4%), L. longipennis (3%), L. trinidadensis (2.7%) and L. whitmani (1.7%). The species were more frequent during the dry season (11) and specimens during the rainy spell (54.6%).KEYWORDS. Amazonia; Ecology; Forest fragments.RESUMO. Flebotomíneos (Diptera, Psychodidae) em reservas florestais da área metropolitana de São Luís, Maranhão, Brasil. Estudou-se a diversidade, a abundância relativa e a sazonalidade das espécies de flebotomíneos em duas reservas de floresta primária alterada, a reserva florestal do Sacavém (RFS) e reserva florestal do Itaqui (RFI), localizadas na área metropolitana de São Luís, capital do estado do Maranhão. Os flebotomíneos foram capturados com armadilhas luminosas tipo CDC, instaladas na borda e no centro da mata, a 1,5 metros de altura, das 18h00 às 6h00, uma vez por mês, durante um ano. No total foram capturados 1.356 indivíduos de 23 espécies dos gêneros Lutzomyia (21) e Brumptomyia (2). Na RFS foram capturados 1.061 espécimes, resultando num esforço de captura de 2,5 indivíduos/hora/armadilha e o predomínio de L. longipalpis (44,8%), seguida por L. antunesi (36,4%), L. sordelli (5,9%), L. flaviscutellata (3,9%) e L. whitmani (2,1%).
