Application of Bark Beetle Semiochemicals for Quarantine of Bark Beetles in China [PDF]
Journal of Insect Science, 2006 This article describes the use of bark beetle semiochemicals for quarantine in China. Using traps with two isomeric compounds of α-pinene, ethanol, trans-verbenol, verbenone, camphene and isononylaldehyde, insects of four families (Scolytidae, Platypodidae, Bostychidae and Cleridae) were trapped, including eight genera of Scolytidae, (Xyleborus ...

, 2023 AbstractBark beetles often feed on dead or dying plant tissues, serving as primary decomposers. However, some bark beetle species kill healthy trees, although at the time of attack, these healthy trees are often experiencing stressful conditions, such as drought or lightning strikes.

Turkish Journal of Agriculture: Food Science and Technology, 2020 Bark beetles (Coleoptera: Curculionidae) are among the important pests of forest in the world and in Turkey. Pine-feeding bark beetles interact chemically with their host tree via the behavioral, physiological, and biochemical effects of one class of ...

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

iForest - Biogeosciences and Forestry, 2011 In natural spruce stands, a change of generation is usually initiated by wind or bark beetle disturbances. We combined semi-temporary monitoring plots, remote sensing, and GIS in order to understand and model these processes.

Chiral escape of bark beetles from predators responding to a bark beetle pheromone [PDF]
Oecologia, 1989 Two species of predatory beetles that locate their prey, Ips pini, by responding to its aggregation pheromone have different chiral preferences to ispdienol than does the herbivore. This suggests that chiral disparity may provide some escape for bark beetles from predation, and that geographic variation in herbivore communication systems may be ...

Frontiers in Microbiology, 2021 Bark beetles (sensu lato) colonize woody tissues like phloem or xylem and are associated with a broad range of micro-organisms. Specific fungi in the ascomycete orders Hypocreales, Microascales and Ophistomatales as well as the basidiomycete Russulales ...

Host tree preference and performance of the Eurasian spruce bark beetle (Ips typographus) on Scots pine. [PDF]
Pest Manag SciIps typographus showed lower reproductive output in an occasional host (Pinus sylvestris) under laboratory conditions, and did not prefer its main host (Picea abies) over P. sylvestris in two‐choice bioassays. Abstract BACKGROUND The Eurasian spruce bark beetle, Ips typographus, is one of the most serious pests of Norway spruce (NS, Picea abies), with ...
