(−)‐myrtenol and (−)‐α‐pinene: Aggregation pheromone components of the cypress bark beetle Phloeosinus aubei

Journal of Applied Entomology, Volume 148, Issue 4, Page 351-363, May 2024.
Abstract The cypress bark beetle, Phloeosinus aubei, is of increasing concern in the European market of scale‐leafed conifers. Neither the reproductive behaviour nor the chemical ecology have been studied in detail so far, and no specific attractant traps are available to monitor the flight of adults.

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 ...

A Population Genetic Model of Evolution of Host-Mate Attraction and Nonhost Repulsion in a Bark Beetle Pityogenes bidentatus

Psyche: A Journal of Entomology, 2012
Studies have shown that the bark beetle Pityogenes bidentatus (Coleoptera, Curculionidae, Scolytinae) avoids volatiles of nonhost trees (Norway Spruce, birch, and oak) and healthy host Scotch Pine when orienting to aggregation pheromone.

Putative ligand binding sites of two functionally characterized bark beetle odorant receptors

, 2021
Background: Bark beetles are major pests of conifer forests, and their behavior is primarily mediated via olfaction. Targeting the odorant receptors (ORs) may thus provide avenues towards improved pest control.

Non-target Bark Beetles in Ips duplicatus (Sahlberg) Pheromone Traps Baited with Host Volatiles

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2015
Response of several non-target bark beetles (Coleoptera: Curculionidae, Scolytinae) to different combinations of the northern spruce bark beetle’s synthetic pheromone with the monoterpenes (-)-alpha-pinene and (+)-limonene has been studied in choice ...

Spruce windfalls and cambioxylophagous fauna in an area with the basic and outbreak state of Ips typographus

Journal of Forest Science, 2006
In spruce windfalls incurred in the autumn and winter season the synusia of cambioxylophagous fauna was evaluated in the profile of a whole stem and crown branches according to the species spectrum, tree cover and intensity of attack.

Discovery of Phloeophagus Beetles as a Source of Pseudomonas Strains That Produce Potentially New Bioactive Substances and Description of Pseudomonas bohemica sp. nov.

Frontiers in Microbiology, 2018
Antimicrobial resistance is a worldwide problem that threatens the effectiveness of treatments for microbial infection. Consequently, it is essential to study unexplored niches that can serve for the isolation of new microbial strains able to produce ...
