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

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

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 ...

Ophiostomatoid fungi isolated from fallen shoots of Scots pine pruned by Tomicus species in Poland [PDF]
Acta Mycologica, 2013 Ophiostomatoid fungi are known to be associated with Tomicus spp. on Pinus sylvestris. However, very little is actually known about the fungi present in the pine shoots damaged by these insects. The aim of this study was to survey species of Ophiostoma s.

Differential patterns of ophiostomatoid fungal communities associated with three sympatric Tomicus species infesting pines in south-western China, with a description of four new species [PDF]
MycoKeys, 2019 Bark beetles and their associated fungi, which cause forest decline and sometimes high mortality in large areas around the world, are of increasing concern in terms of forest health. Three Tomicus spp. (T. brevipilosus, T. minor and T.

Forest Pathology, Volume 53, Issue 6, December 2023., 2023 Abstract The forest pathogen, Heterobasidion irregulare, is a serious threat to conifers in North America including Minnesota. Fungi native to Minnesota were isolated and tested in laboratory and field assays to evaluate their antagonism towards H. irregulare. One management strategy for plant pathogens, and especially H. irregulare, is to use fungi as

Journal of Applied Entomology, Volume 147, Issue 10, Page 941-952, December 2023., 2023 Abstract As walnut trees (Juglans spp.) are of high economic importance, considerable attention has been given to invasive pests of these trees in Europe. In 2016, Dryocoetes himalayensis Strohmeyer, 1908, an alien bark beetle originating from the Himalayas region of India, already present in several European countries, was confirmed to have attacked ...
