In recent years in pine stands of Eastern Polissya there is a group drying of trees by the top type. In the foci of drying, Ips acuminatus predominantly colonizes the trees resulting in a rapid loss of their vitality. The insects develop under thin bark of the top stem part, mainly focusing on a relative height of 0.5–0.8. Production of bark beetle in populated area reaches 100 specimens per dm2 of surface. In the winter period Ips acuminatus can survive at the stage of a larva or imago in the area of the transitional bark at a relative height of the tree of 0.2–0.5. The removal of freshly colonized pine trees in the foci of drying by sanitation felling in the autumn-winter period is an effective method for reducing the number of bark beetles before the beginning of its swarming and colonizing trees in the spring.
