Automated Optimal Motion Sequence of a 9-Bar Linkage

Frontiers in Built Environment, 2020
Automated optimization-driven analyses may lead to an emersion of innovative design approaches, while investigating the potentials in design, analysis and control of high-performance engineering structures, and adaptive architecture. In the present study,

Potential applicability of SPLAT® Verb for management of European spruce bark beetle, Ips typographus (L.)

Journal of Applied Entomology, Volume 148, Issue 10, Page 1157-1171, December 2024.
Abstract The European spruce bark beetle, Ips typographus (L.), is the most important forest pest in Europe due to the profound impacts of periodic outbreaks on ecosystem goods and services. Herein, we evaluated the responses of I. typographus to different doses of verbenone (SPLAT® Verb, 10% (−)‐verbenone by weight; ISCA Inc., Riverside, CA, USA) in ...

Bark beetles on logging residues of European larch: Effects of shading and diameter of logging residues on infestation density

Agricultural and Forest Entomology, Volume 26, Issue 4, Page 457-469, November 2024.
Abstract Ips cembrae, an important pest of European larch (Larix decidua), has caused local outbreaks in the last two decades and is becoming increasingly important as the proportion of European larch in forests increases. In 2021–2023, larch logs and piles of branches were placed into shaded forest and sunlit areas every month to study bark beetle ...

Host tree and insect genetic diversity on the borderline of natural distribution: a case study of Picea abies and Pityogenes chalcographus (Coleoptera, Scolytinae) in Greece

Silva Fennica, 2011
Picea abies (L.) Karst. and Pityogenes chalcographus constitute a commonly observed host tree–insect association in Eurasia, with the natural distribution of the bark beetle overlapping that of Norway spruce.

Debarking harvesters simultaneously combat the European spruce bark beetle (Ips typographus) and conserve non‐target beetle diversity

Ecological Solutions and Evidence, Volume 5, Issue 3, July–September 2024.
The European Spruce Bark Beetle can be effectively reduced by using the debarking head for harvesters and the bark gouging device for motor manual bark treatment. The new methods do not reduce non‐target beetle species and do not rely on transport capacities for successful pest control.

Mitochondrial phylogenies in the light of pseudogenes and Wolbachia: re-assessment of a bark beetle dataset

ZooKeys, 2010
Phylogenetic studies based on mtDNA become increasingly questioned because of potential pitfalls due to mitochondrial pseudgenes and mitochondrial selective sweeps.

Genetic variation reveals complex population structuring of Tomicus piniperda L. (Coleoptera, Scolytidae) in the UK: Implications for management of this important pest

Agricultural and Forest Entomology, Volume 26, Issue 2, Page 249-261, May 2024.
Abstract Tomicus piniperda is a common pest of pine trees responsible for significant economic damage. Although the impact of T. piniperda on forestry is likely to increase in the future due to climate change, little is known about its dispersal within the United Kingdom (UK) or between continental Europe and the UK.

Effect of culture media on radial growth and fructification of ophiostomatoid fungi isolated from bark beetles

Folia Oecologica
Ophiostomatoid fungi are important associates of bark beetles (Scolytinae) and cause sapstain and tracheomycosis in trees. We examined the growth and fructification of seven species from the genera Ophiostoma, Graphilbum, Leptographium, and Grosmannia ...
