WEEVIL COMMUNITIES (COLEOPTERA, CURCULIONIDAE) ON THE ROSACEOUS WOODY-PLANTS IN SW SLOVAKIA

In the periods of 1979-1981 and 1992-1994 the structure of weevil comm unities occurring: on four wild rosaceous woody plants (Crataegus mono gyna, Pyrus communis, Prunus spinosa and Rosa spp.) was studied in the Little Carpathians and Podunajska nizina lowland. Altogether we recor ded occurrence of 97 species belonging to 34 genera. The stratocoenose s on hawthorns exhibited the highest species number (70 species of 22 general and alpha-diversity. The communities on black thorn consisted of 44 weevil species of 19 genera and exhibited the lowest alpha-diver sity. On wild roses we recorded 41 species of 21 genera and on wild pe ar-trees 37 species of 16 genera, respectively.
