Abstract

The old-growth endemic Imeretian oak [Quercus robur subsp. imeretina (Steven ex Woronow) Menitsky, 1968] is a protected relict Tertiary period tree still preserved in Ajameti Managed Reserve (Republic of Georgia). For a long time, these forests were experienced to the strong anthropogenic influence. The old-age oak trees and the development of root and stem rot have promoted the settlement of great capricorn beetle [Cerambyx cerdo Linnaeus, 1758 (Coleoptera: Cerambycidae)]. Both of species are protected under the EU Habitats Directive and listed in the IUCN Red List of Threatened Species. The investigation of settling degree of C. cerdo was conducted at two areas, Ajameti and Vartsikhe, on the edge and in the middle of oak forests in June and October 2014. On both the areas, the number of trees with fly exit holes of great capricorn beetle was higher on the margin of forests where plantations suffer greater of human impact. The number of fly exit holes of imago is significantly increased due to deterioration of sanitary condition of forests. The measures of management conservation at Ajameti Managed Reserve were proposed.
