Acuatic Insects at Southeast of Wetlands in the Tres Palos Lagoon, Acapulco, Guerrero, Mexico

Abstract

Aquatic environment alteration is reflected in the biodiversity of the ecosystem, aquatic insects are used to evaluate the anthropogenic impact. In the dry season (May-June) the samples are taken in 13 collection sites in the area of wetlands. Low diversity (22 genera) is presented, the most abundant and widely distributed species corresponded to Notonecta undulata and Hetaerina americana (Hemiptera and Odonata, respectively). The Tipula sp (Diptera) recorded partial distribution and local distribution Potanamus rofous (Ephemeroptera). The 91 BMWP index corresponds to a moderate pollution degree with eutrophy.
