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 (Gruza, Grosnica, Sumarice 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).
