“…Pramual and Kuvangkadilok (2009) and Pramual and Wongpakam (2010), reported an average of 2.5 and 2.2 species per stream site, respectively, from the northeastern region of Thailand, and an average species number of 2.2-3.3 was reported from Brazil, in South America (Hamada et al, 2002;Landeiro et al, 2009;McCreadie et al, 2006).…”

“…Other environmental changes that are associated with enrichment, i.e., alteration of the flow regime and changes in streamside vegetation, can influence the distribution and abundance of black flies (Pachón and Walton, 2011). Several studies on black fly communities associated with environmental factors have been reported from various parts of the world, though, mostly from America, Europe and Africa (McCreadie et al, 2006;Landeiro et al, 2009;Pachón and Walton, 2011;Figueiró et al, 2012;Rabha et al, 2013). Similar studies have been carried out on the planes of northeastern Thailand (Pramual and Kuvangkadilok, 2009;Pramual and Wongpakam, 2010).…”

This is the first study on the seasonal biodiversity of black flies and evaluation of ecological factors influencing their distribution at Doi Pha Hom Pok National Park, northern Thailand. Larvae were collected from six fixed-stream sites in relation to altitude gradients from May 2011 to April 2013. The water temperature, water pH, conductivity, total dissolved solids (TDS), salt, water velocity, stream width and depth, streambed particle sizes, riparian vegetation, and canopy cover were recorded from each site. Monthly collections from the six sites yielded 5475 last-instar larvae, belonging to 29 black fly species. The most frequently found species from all sites were Simulium asakoae (100%) followed by Simulium yuphae (83.3%), and Simulium chiangdaoense, Simulium gombakense, Simulium phahompokense, Simulium fruticosum, Simulium maeaiense and Simulium fenestratum (66.6%). Of the 5475 last-instar larvae, S. maeaiense (19.3%), S. chiangdaoense (15.8%) and S. asakoae (14.8%), were the three most abundant species. The Shannon diversity index (H) at the six sites with different altitudes of 2100m, 2000m, 1500m, 1400m, 700m, and 500m above mean sea level, were 2.042, 1.832, 2.158, 2.123, 1.821 and 1.822, respectively. The Shannon index and number of taxa in the cold season were higher than those in the rainy and hot seasons. Principal component analysis (PCA) indicated that at least three principal components have eigen values >1.0 and accounted for 93.5% of the total variability of ecological factors among sampling sites. The Canonical correspondence analyses (CCA) showed that most species had a trend towards altitude, canopy cover, riparian vegetation and water velocity.

“…The present study, together with the work of Landeiro et al (2009), stands as one of the first contributions to the literature about the ecological traits of the Brazilian cerrado black flies. Although biotic factors can influence community structure in lotic systems, abiotic factors probably play a dominant role in defining species assemblages (Allan 1995).…”

“…Another issue raised in Hamada et al (2002) is that most of the studies on Neotropical black flies approach the ecology of the individual species population (e.g., Hamada & McCreadie 1999), rather than the whole black fly community. In recent years, some authors attempted to research the ecology of the black fly community (Hamada et al 2002, McCreadie et al 2004, Pepinelli et al 2005, Figueiró et al 2006, 2008, Landeiro et al 2009); however, contributions to this particular field of Neotropical black fly ecology are still very limited. The cerrado is a savanna biome characterized by low pH dystrophic soils, little availability of calcium and magnesium and high aluminium content (Furley & Ratter 1988).…”

Black flies have medical importance because some species are vectors of the Onchocerciasis and Mansonelosis, nevertheless, their ecology and potential use as bioindicators is still poorly studied in the Neotropical Region. In Brazil, bioindicators use is strongly focused in a multimetrical ecological index approach; this way, we investigated the black fly spatial distribution, in relation to abiotic factors correlated to water quality, to provide baseline information for their utilization as standalone indicators of lotic systems integrity. We have tested the hypothesis that environmental changes related to urbanization, lead to decreased abundance and loss in the number of species of the black fly fauna. The sampling was conducted in 10 urban and 10 preserved streams during the dry season (August-September) of 2012, in the mountainous region of Teresópolis, State of Rio de Janeiro, Brazil. The streams were characterized for their environmental integrity conditions and physico-chemical properties of water. In each stream, five different rapid points were sampled in a section of 50 meters, 10 meters apart from each other. The black flies were sampled with a kick-net sampler on rocky substrates. The material was separated and the larvae were sorted in morphotypes, and later, the final instar specimens were dissected and identified with the help of taxonomical literature at species level. A total abundance of 488 larvae from nine species were collected, 5 (1.02 %) in extremely impacted streams, 470 (96.31 %) in intermediate streams and 13 (2.66 %) in preserved streams. The visual evaluation (HII) differed in relation to the water physico-chemical evaluation, in which more variation in the characterization of the sampling sites was observed. In Canonical Correspondence Analysis Simulium subpallidum, S. inscrustatum and S. pertinax were significantly associated with intermediate values of most of the variables, and then to intermediate impacted sites. On the other hand, Lutzsimulium hirticosta, S. subnigrum and Simulium sp. A were associated to low values of chemical variables, and then to more preserved sites. Most studies on the bioindicator potential of Simuliidae have suggested an approach to agricultural impacts, while our results, on the other hand, showed that Simuliidae species were present in streams with intermediate urban pollution impacts, but absent in heavily impacted sites. Thus, our data suggested that some species are associated to more pristine breeding sites, such as L. hirticosta and Simulium sp. A, while others may be good bioindicators of moderately impacted streams, such as S. pertinax, S. subnigrum and S. subpallidum. Rev. Biol. Trop. 63 (3): 683-693. Epub 2015 September 01.
