Abstract: In 25 to 40-years-old stands damaged by snow in the Beskids, the fauna of cambioxylophages was analyzed both on standing breaks and lying break-off stems. Breaks are characterized by the gradually drying phloem, watered phloem and secondary fauna (Hylurgops palliatus, Hylocoetes dermestoides, Dryocoetes sp., Monochamu sp.), which does not represent any danger to spruce stands. The phloem on lying breaks withered and died till the end of the growing season. The competing species Pityogenes chalcographus (L.) (46-52% cov-er) and species of the genus Dryocoetes (20% cover) colonized the breaks in particular. The upper and the lower side of the lying breaks-off differ in the intensity of attack and the degree of cover of these species. In young broken and open stands with the unprocessed wood of lying breaks-off there occurs a risk of the creation of bark beetle circles in the subsequent year after the damage.
