Contribution to the knowledge of beech bark disease in the Magura working-plan area, West Carpathian mountains.
Abstract
Occurrence of beech bark necrosis, the beech scale insect (Cryptococcus fagi [Cryptococcus fagisuga]) and feeding by larvae of the butterfly Ectoedemia liebwerdella, and several site attributes, were evaluated for 1163 beech (Fagus sylvatica) trees in a 1800 ha area at Strážovských in the West Carpathian region of Slovakia. The influence of the various factors measured on the occurrence of beech bark necrosis was analysed. Neither the beech scale insect nor feeding by E. liebwerdella larvae had a significant influence on the presence of bark necrosis. Unfavourable site conditions, such as shallow soils, steep slopes and south to east exposures had some influence on the occurrence of the disease.
