Isolation of fungi associated with ambrosia beetles with pre-oral mycangia v1
, 2021 This protocol describes how to extract fungi from ambrosia beetles that have pre-oral mycangia. Note: This protocol is specific for ambrosia beetles with pre-oral mycangia and may not be useful for beetles with different mycangia types. This protocol is part of the Bark Beetle Mycobiome (BBM) Research Coordination Network. For more information on the

Three genera in the Ceratocystidaceae are the respective symbionts of three independent lineages of ambrosia beetles with large, complex mycangia [PDF]
Fungal Biology, 2015 The genus Ambrosiella accommodates species of Ceratocystidaceae (Microascales) that are obligate, mutualistic symbionts of ambrosia beetles, but the genus appears to be polyphyletic and more diverse than previously recognized. In addition to Ambrosiella xylebori, Ambrosiella hartigii, Ambrosiella beaveri, and Ambrosiella roeperi, three new species of ...

Ecological and Evolutionary Determinants of Bark Beetle —Fungus Symbioses
Insects, 2012 Ectosymbioses among bark beetles (Curculionidae, Scolytinae) and fungi (primarily ophiostomatoid Ascomycetes) are widespread and diverse. Associations range from mutualistic to commensal, and from facultative to obligate.

Insects, 2018 Like other members of the tribe Xyleborini, Xyleborus bispinatus Eichhoff can cause economic damage in the Neotropics. X. bispinatus has been found to acquire the laurel wilt pathogen Raffaelea lauricola (T. C.

Mycoscience, 1995 A fungus was found to be stored in the mycangia of a horntail,Tremex longicollis, as hyphal fragments. All fungal isolates from the mycangia of 31 adult females of the horntail produced the same colonies on PDA. Basidiocarps ofCerrena unicolor occurred near the emergence hole of the horntail on a dead hackberry tree (Celtis sinensis).

Advances in research on autophagy in the maintenance of insect–microbe symbiosis
New Plant Protection, Volume 3, Issue 3, September 2026.Autophagy plays a dual regulatory role in insect–microbe symbiotic relationships. Beneficial symbiotic bacteria in insects participate in nutrient exchange via the TOR pathway, whereas pathogenic microbes induce immune defense through the AMPK pathway. Autophagy‐related genes regulate development and pathogen clearance during this process.

Forest Pathology, Volume 56, Issue 2, April 2026.ABSTRACT Oak wilt, caused by Bretziella fagacearum, is a destructive vascular disease of oaks in North America, yet fine‐scale spatial localisation of the pathogen in host tissues and on insect vectors remains poorly characterised. In this study, we developed and validated a species‐specific fluorescence in situ hybridisation (FISH) probe targeting the

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 49-60, February 2026.Abstract Wood boring ambrosia beetles play a central role in the spread of Ceratocystis wilt of ‘ōhi‘a, a fungal disease caused by Ceratocystis lukuohia that kills the bioculturally important ‘ōhiʻa (Metrosideros polymorpha) tree. Beetles contribute to the spread of the disease by extruding fungus‐infected wood particles (frass). Disease mitigation can

Commodity risk assessment of oak and walnut logs from the US
EFSA Journal, Volume 24, Issue 1, January 2026.Abstract The European Commission submitted to the EFSA Panel on Plant Health a Dossier from the United States proposing the use of a vacuum–steam–heat treatment as a stand‐alone phytosanitary measure to mitigate the risk of entry of Bretziella fagacearum, Geosmithia morbida and its vector Pityophthorus juglandis (thousand cankers disease complex) into ...

Forest Pathology, Volume 55, Issue 4, August 2025.ABSTRACT Woodwasps of the genus Sirex are known to have an obligatory symbiotic relationship with Amylostereum fungi. During oviposition, these wasps inoculate arthrospores of the fungus along with a toxic mucous secretion. As a result, attacked conifer trees can exhibit symptoms of decline and death. The aim of this study was to evaluate the diversity
