The European spruce beetle (Dendroctonus micans (Kug.)) is a xylophagus, a pest of coniferous trees. Its mass reproduction outbreaks can lead to whole forests dying on a large territory. Dendrocton damages both natural and artificially created forest plantations, especially growing in tense environmental conditions: beyond the main area, under the conditions of a non-optimal hydrological regime of soils, as well as forests, disturbed by intensive recreation or man-made impact. Since the mid-seventies of the 20th century, there has been a sharp activation of this pest in Western and Eastern Siberia. The mass foci of reproduction of this beetle, along with other forest insect pests, are regularly observed in the south of the Tyumen Region.

This article analyzes the state of forest cultures of Scots pine in two foci of European spruce beetle in the south of the Tyumen Region (the Aromashevsky and Omutinsky Districts). The assessment of the degree of damage to the trees by the beetle employs counting the number of entrance apertures on the trunks. The results show that the state of pine trees in forest cultures is determined both by pest influence and by natural processes of competitive thinning. The trees of the best and worst categories of vital state are the most susceptible to pest settlement, while average trees are damaged less frequently. The highest point of the beetle’s intrusion and the spread of the entrance apertures along the trunk height are characteristic for trees with weak invasion. There is no established connection between morphometric characteristics of trees and the degree of damage by their beetle.
