Aquatic weevil (Coleoptera: Curculionoidea) assembly response to the different ecological conditions in artificial lakes in central Serbia

Abstract

Artificial stagnant aquatic ecosystems such as reservoirs, are suitable for monitoring the succession of biocenoses because they are usually formed by rearrangement of the former current river ecosystems. The weevil assembly, as part of such a dynamic biocenose, develops following host macrophytes. In the frame of weevil fauna studies realized during 2001 and 2002 in wet habitats beside four artificial lakes in Central Serbia (Gruža, Grošnica, Šumarice and Bubanj), the aquatic adults from 13 species, divided into two families, Eryrhinidae (Tanysphyrus lemnae and Notaris scirpi) and Curculionidae (Bagous bagdatensis, B. collignensis, B. lutulentus, Pelenomus canaliculatus, P. comari, P. waltoni, Phytobius leucogaster, Rhinoncus castor, R. inconspectus, R. pericarpius and R. perpendicularis), were collected. The quantitative and qualitative picture of the studied aquatic weevil assemblies, as well as indices of similarity among them, are given and related to the dimensions and ecological characteristics of studied aquatic systems (particularly the level of eutrophication).
