- Abstract
Distribution of entomofauna associated with aquatic macrophytes in the reflux of the Correntoso river, Pantanal do Negro, Mato Grosso do Sul State, Brazil. This work aimed ato research the distribution of insects associated with aquatic macrophytes and the similarity among collection sites during the reflux period in a stretch of Correntoso river, Pantanal do Negro, Mato Grosso do Sul State, Brazil. The collection sites were determined by changes in the riparian formation structure, characterized as open when there is communication with flooded fields and intermediary and closed when there is not any communication with flooded fields. Three collections were taken at six sample sites, during reflux periods. The organisms were collected using a D net, 300 μm mesh, with samples from five nets thrown in roots of aquatic macrophytes. Family richness, absolute and relative abundance of the insects found, and similarity of collection sites were analyzed using Euclidian distance and complete connection, Shannon-Wiener diversity index, with log2. Sixty-four families from 10 orders of Hexapoda class were registered, totaling 2,525 individuals - 2,405 of them aquatic and semiaquatic, and 120 terrestrial. The collect sites did not present a fixed model of similarity, and the formation of groups occurred in distinct forms at each collection.
