Induced terpene accumulation in Norway spruce inhibits bark beetle colonization in a dose-dependent manner [PDF]

, 2011
Background: Tree-killing bark beetles (Coleoptera, Scolytinae) are among the most economically and ecologically important forest pests in the northern hemisphere.

2-methyl-3-buten-2-ol: a pheromone component of conifer bark beetles found in the bark of nonhost deciduous trees [PDF]

, 2012
Volatiles from bark of aspen,Populus tremulaL. and two species of birch: silver birch (Betula pendulaRoth.) and common birch (B. pubescensEhrh.), were collected by direct solvent extraction and aeration of both newly cut bark chips and undamaged stems in

Tracking the spread of the northern bark beetle (Ips duplicatus [Sahlb.]) in Europe and first records from Switzerland and Liechtenstein [PDF]

Alpine Entomology, 2020
The northern bark beetle (Ips duplicatus), in Europe originally restricted to northern countries, expanded its distribution range to eastern Europe in the 20th century and is now causing considerable damage in spruce forests.

Semiochemical diversity in practice [PDF]

, 2012
Reduction of tree mortality caused by bark beetle attacks is not only important for forestry, but is essential for the preservation of biodiversity and forest carbon sinks in the face of climate change. While bark beetle mass trapping (a "pull" approach)

Multispectral Imagery Provides Benefits for Mapping Spruce Tree Decline Due to Bark Beetle Infestation When Acquired Late in the Season

Remote Sensing, 2022
Climate change is increasing pest insects’ ability to reproduce as temperatures rise, resulting in vast tree mortality globally. Early information on pest infestation is urgently needed for timely decisions to mitigate the damage.

Forest Disturbances Threatening Cypripedium calceolus Populations Can Improve Its Habitat Conditions

Diversity, 2023
Inappropriate forest management activities, above all clear-cutting, are recognized as the major threats to an iconic orchid species—the lady’s slipper orchid (Cypripedium calceolus), the flagship species of nature protection in Europe.

A bark beetle infestation predictive model based on satellite data in the frame of decision support system TANABBO

iForest - Biogeosciences and Forestry, 2020
The European spruce bark beetle Ips typographus L. causes significant economic losses in managed coniferous forests in Central and Northern Europe. New infestations either occur in previously undisturbed forest stands (i.e., spot initiation) or depend on

Non-host volatile blend optimization for forest protection against the European spruce bark beetle, Ips typographus. [PDF]

PLoS One, 2014
Conifer feeding bark beetles (Coleoptera, Curculionidae, Scolytinae) pose a serious economic threat to forest production. Volatiles released by non-host angiosperm plants (so called non-host volatiles, NHV) have been shown to reduce the risk of attack by many bark beetle species, including the European spruce bark beetle, Ips typographus.

Comparison of Deep Neural Networks in the Classification of Bark Beetle-Induced Spruce Damage Using UAS Images

Remote Sensing, 2023
The widespread tree mortality caused by the European spruce bark beetle (Ips typographus L.) is a significant concern for Norway spruce-dominated (Picea abies H.
