Microbiota‐Mediated Sequential Gallery Colonization by Adults and Larvae of an Invasive Bark Beetle

Integrative Zoology, EarlyView.
Dispersing adult beetles harbor more pinitol‐degrading microbes to colonize novel host pines with high levels of pinitol stress. These microbes from the beetle's exoskeleton and gut will be transmitted into the gallery via adults’ feeding and frass, whose proliferation in the gallery contributes to the formation of a low‐pinitol microhabitat.

Spatial Genetic Structure of the Insect-Vectored Conifer Pathogen Leptographium wageneri Suggests Long Distance Gene Flow Among Douglas-fir Plantations in Western Oregon

Frontiers in Forests and Global Change, 2021
Many fungi in the Ophiostomatales are vectored by bark beetles that introduce these fungi directly into their tree hosts. Most of these fungal associates have little effect on their hosts, but some can cause serious diseases.

Temperature interacts with jack pine host defences to influence the growth of mountain pine beetle‐associated fungi

Agricultural and Forest Entomology, Volume 28, Issue 4, Page 525-534, November 2026.
Optimal growing temperatures varied with mountain pine beetle‐associated fungal species. There was only a marginal impact of temperature on the response of fungi to defensive monoterpenes of novel host pine. Interspecific facilitation occurred for Leptiographuim longiclavatum when grown in Ophiostoma montium‐induced treatments at optimal temperatures ...

In California's Changing Climate, Latent Pathogens Drive Novel Woody Plant Diebacks on a Large Geographic Scale

Plant Pathology, Volume 74, Issue 9, Page 2697-2714, December 2025.
Novel plant diebacks are emerging in association with reoccurring droughts in California. Field isolations and greenhouse trials show that latent pathogens and drought together, and not drought alone, cause the most severe diebacks. ABSTRACT The detection of emergent biotic and abiotic threats to plant health is challenging in an interconnected world ...

Grosmannia and Leptographium spp. associated with conifer-infesting bark beetles in Finland and Russia, including Leptographium taigense sp. nov.

Antonie van Leeuwenhoek, 2012
Species of Grosmannia with Leptographium anamorphs include important forest pathogens and agents of blue stain in timber. They are commonly found in association with forest pests, such as bark beetles. During a survey of ophiostomatoid fungi in eastern parts of Finland and neighboring Russia, species belonging to the genus Grosmannia were isolated from

Special delivery: A hardwood‐killing bark beetle vectors its unusual symbiote among host trees

Ecosphere, Volume 16, Issue 5, May 2025.
Abstract In mutualistic symbioses with fungi, herbivorous insects such as bark beetles (Coleoptera: Curculionidae: Scolytinae) gain access to resources that are unavailable in the absence of fungal mutualists, while fungi benefit from insect‐vectored dispersal. The most well‐studied mutualists of tree‐killing bark beetles in conifer systems are certain

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 ...
