Bark Beetles, Pityogenes bidentatus, Orienting to Aggregation Pheromone Avoid Conifer Monoterpene Odors When Flying but Not When Walking [PDF]

open access: goldPsyche: A Journal of Entomology, 2012
Previous studies and data presented here suggest that odors from healthy host Scotch pine (Pinus sylvestris) and nonhost Norway spruce (Picea abies), as well as major monoterpenes of these trees at natural release rates, significantly reduce the ...

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

open access: goldPsyche: 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.

Bursaphelenchus pinophilus Brzeski & Baujard, 1997 (Nematoda: Parasitaphelenchinae) associated with nematangia on Pityogenes bidentatus (Herbst, 1783) (Coleoptera: Scolytinae), from the Czech Republic [PDF]

open access: bronzeNematology, 2012
The occurrence of Bursaphelenchus species in the Czech Republic is poorly known, the first report of the genus being made by Kubátová et al. (2000) who reported the association of B. eremus with the hyphomycetous microfungus, Esteya vermicola, and the bark beetle, Scolytus intricatus, collected from Quercus robur, in central Bohemia.

Symbiosis and pathogenicity of Geosmithia and Talaromyces spp. associated with the cypress bark beetles Phloeosinus spp. and their parasitoids. [PDF]

open access: yesEnviron Microbiol, 2022
Summary Fungi associated with cypress bark beetles are practically unknown in the Eastern Mediterranean. Our study focused on the fungi associated with the body parts and galleries of two indigenous cypress bark beetles, Phloeosinus armatus and P. bicolor, sampled from Cupressus sempervirens trees in different regions in Israel. Arbitrarily primed PCR,

List of non-EU Scolytinae of coniferous hosts. [PDF]

open access: yesEFSA J, 2020
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health prepared a list of non‐EU Scolytinae spp. (Coleoptera: Curculionidae) affecting coniferous hosts. A literature review and search of databases, conducted up to January 2019, identified 804 Scolytinae species and subspecies of coniferous hosts. These Scolytinae were

Divergent Trends in Insect Disturbance Across Europe's Temperate and Boreal Forests. [PDF]

open access: yesGlob Chang Biol
Across temperate and boreal Europe, tree mortality caused by insects has risen during the 21st century, yet interactions among insect species and their host trees are complex. While mortality from wood‐boring insects in conifers has increased, defoliation caused by multiple moth species has declined.
