Spatial and temporal patterns of bark beetle and defoliator outbreaks, and their interactions, in the Pacific Northwest. [PDF]

open access: yesEcol Appl
Abstract The dynamics of many forest insects are changing in response to climate warming; however, patterns are not always consistent among or within taxa. Changes in outbreak dynamics for individual species have received much recent attention, but the potential for interactions among species has received less.

Limited tree mortality in unburned areas linked to bark beetle spillover from wildfires. [PDF]

open access: yesEcol Appl
Abstract Increased fire activity in the western United States since 2000 has produced an abundance of fire‐injured trees at risk to lethal attack by bark beetles. Large populations of bark beetles reproducing in fire‐injured trees may disperse (or spillover) from inside the fire perimeter to adjacent, unburned forests, potentially causing extensive ...

Water, not carbon, drives drought-constraints on stem terpene defense against simulated bark beetle attack in Pinus edulis. [PDF]

open access: yesNew Phytol
Summary Drought predisposes forest trees to bark beetle‐induced mortality, but the physiological mechanisms remain unclear. While drought‐induced water and carbon limitations have been implicated in defensive failure and tree susceptibility, evidence demonstrating how these factors interact is scarce.

Pine engraver beetle Ips acuminatus as a potential vector of Sphaeropsis sapinea

open access: yesForestry and Forest Melioration, 2020
The pine engraver beetle Ips acuminatus Gyll. is a potential vector of the Sphaeropsis tip blight pathogen according to Leach’s postulates. The specimens of I. acuminatus were associated with numerous fungi species, namely Sphaeropsis sapinea (Fr.) Dyko & B. Sutton and ophiostomatoid species.

Temporal variation in contamination of pine engraver beetles with Fusarium circinatum in native Monterey pine forests in California [PDF]

open access: yesPlant Pathology, 2008
The relative importance of beetle species associated with Fusarium circinatum ‐infected Monterey pines was investigated in three Monterey pine forests along the coast of central California, USA from April to November in 2004 and 2005. Fusarium circinatum

A comparative characteristic of fungal communities associated with Ips acuminatus in different regions of Ukraine

open access: yesНаукові праці Лісівничої академії наук України, 2019
Pine bark beetles are typically associated with complexes of fungi that could reveal different functional interaction. Thus, previously nonaggressive bark beetle Ips acuminatus is considering now to be among the most serious pests of pine forest in ...

Fungi associated with Ips acuminatus (Coleoptera: Curculionidae) in Ukraine with a special emphasis on pathogenicity of ophiostomatoid species

open access: yesEuropean Journal of Entomology, 2017
Conifer bark beetles are well known to be associated with fungal complexes, which consist of pathogenic ophiostomatoid fungi as well as obligate saprotroph species.

Parameters of Pinus sylvestris health condition and Ips acuminatus population in pure and mixed stands of Sumy region

open access: yesНаукові праці Лісівничої академії наук України, 2020
Outbreaks of bark beetles have increased in recent years in various regions. Pine engraver beetle (Ips acuminatus (Gyllenhal, 1827); Coleoptera: Curculionidae: Scolytinae) is most common in the pine forests of many European countries.
