Induced Terpene Accumulation in Norway Spruce Inhibits Bark Beetle Colonization in a Dose-Dependent Manner [PDF]

PLoS ONE, 2011
Tree-killing bark beetles (Coleoptera, Scolytinae) are among the most economically and ecologically important forest pests in the northern hemisphere. Induction of terpenoid-based oleoresin has long been considered important in conifer defense against ...

Meteorological and climatological triggers of notable past and present bark beetle outbreaks in the Czech Republic [PDF]

Climate of the Past, 2022
Based on documentary evidence, a chronology of bark beetle outbreaks in the Czech Republic from 1781 to 1963 CE was created, continuing from 1964 through 2021 by bark beetle salvage felling data.

Physiological and biochemical indicators in Norway spruces freshly infested by Ips typographus: potential for early detection methods

Frontiers in Forests and Global Change, 2023
IntoductionThe bark beetle Ips typographus currently represents the primary pest of Norway spruce (Picea abies) in Central Europe. Early detection and timely salvage cutting of bark beetle-infested trees are functional management strategies for ...

Response of moth communities (Lepidoptera) to forest management strategies after disturbance

European Journal of Entomology, 2023
Spruce forests face many threats such as climate change and bark beetle outbreaks. Yet, bark beetle dynamics have a long co-evolutionary history strongly linked to spruce forest structural dynamics.
