Abstract

To understand the relationship between environmental factors and black fly (Simuliidae) species’ distributions, we sampled immature individuals in Pedra Branca State Park, Rio de Janeiro, Brazil, during the dry season in June 2018. We then correlated environmental variable values with black fly larvae abundances via redundancy analyses. The abundances of Simulium pertinax Kollar 1832, Simulium subpallidum Lutz 1910, Simulium (Thyrsopelma) spp., Simulium (Psaroniocompsa) spp., and Simulium (Inaequalium) spp. were negatively correlated with light and temperature, while Simulium (Hemicne tha) spp.’s abundance correlated positively with these variables. The abundances of Simulium pertinax Kollar 1832, Simulium (Hemicnetha) spp., and Simulium (Thyrsopelma) spp. were positively associated with altitude, while the abundances of the other species revealed negative correlations with this factor. Species richness was determined using pupae in a linear regression with the Ephemeroptera, Plecoptera Trichoptera (EPT) index. This analysis showed that the most deteriorated sites have a higher species richness than more conserved sites within Pedra Branca State Park. Our results suggest that simuliid species richness reflects habitat integrity, thus becoming a reliable indicator of habitat conservatio status.
