Biological techniques are used where no possibility for chemical spraying occurs. Rumex confertus Willd. is an example of a plant-eater which is potentially more important than chemical compounds. The objective of the study was to evaluate population dynamics and the development of l-fypera rumicis L. ( Coleoptera, Cucurlionidae) on Rumex confer/us Willd. as well as to determine effects of the injuries on growth of a plant.}, type={Article}, title={The occurrence of Hypera rumicis L.
