    Description

    Several species of bark beetles occur frequently in the upland spruce forests of the Czech Republic; some of them are serious pests that may cause vast destruction of forest stands. In the last decade, a complex of several species from the genera Ips, Pityogenes and Polygraphus contributed to large-scale devastation of thousand hectares of spruce forest in the Sumava Mountains and in Northern Moravia. To understand the course of such outbreaks and to appreciate the role of natural enemies in bark beetle population dynamics, we investigated the importance of braconid parasitoids that attack several species of bark beetles.
