DORNFELD, Carolina Buso  e  FONSECA-GESSNER, Alaide A.. Chironomidae (Diptera) fauna associated to Salvinia sp. and Myriophyllum sp. in a Corrego do Espraiado reservoir, São Carlos, São Paulo, Brasil. Entomol. vectores [online]. 2005, vol.12, n.2, pp. 181-192. ISSN 0328-0381.  http://dx.doi.org/10.1590/S0328-03812005000200005.

The presence of vegetation in aquatic ecosystems often results in a substantial increase in the available area for colonization. Several studies have demonstrated a positive relationship between the presence of macrophytes and the abundance and diversity of Chironomidae. Environmental parameters and Chironomidae larvae associated with both macrophytes Salvinia sp. and Myriophyllum sp. were studied in a small reservoir in the state of S. Paulo, Brazil. Tanytarsus, Monopelopia and Labrundinia were dominant in abundance on Salvinia, however Cricotopus and Tanytarsus have alternated dominance on Myriophyllum. In addition the structure functional feeding groups were discussed.
