Appropriate management of invasive fungi requires adequate understanding of their global diversities and movement histories. The fungus Leptographium procerum is associated with root-colonizing forest insects in pine forests throughout the world, and may have contributed to the aggressive behaviour ...

The ascomycete genus Ceratocystis (Microascales, Ceratocystidaceae) includes important fungal pathogens of trees, including Eucalyptus species. Ceratocystis species and their Thielaviopsis asexual states are typically associated with insects, such as nitidulid beetles, that spread them over long...

In Oman, the bark beetle Hypocryphalus mangiferae is closely associated with trees affected by mango sudden decline disease caused by Ceratocystis manginecans. Although it has previously been assumed that this beetle plays a role in the dispersal of the pathogen, this has not been established...

Fungi in the Ophiostomatales include important pathogens of trees as well as agents of wood stain, reducing the economic value of timber. They rely on insects, such as bark beetles, for dispersal and are commonly associated with wounds on trees. Although Ophiostoma spp. have been reported from...

Novel genotypes often arise during biological invasions, but their role in invasion success has rarely been elucidated. Here we examined the population genetics and behavior of the fungus, Leptographium procerum, vectored by a highly invasive bark beetle, Dendroctonus valens, to determine whether...

Recent studies have investigated the relationships between pairs or groups of exotic species to illustrate invasive mechanisms, but most have focused on interactions at a single trophic level. Here, we conducted pathogenicity tests, analyses of host volatiles and fungal growth tests to elucidate an ...

It is well recognised that pests and pathogens are increasingly threatening both natural woody ecosystems and plantation forestry world-wide. This threat is largely connected to the increasing movement of people and products globally, with concomitant introductions of pests and pathogens into new...

The white rot fungus, Amylostereum areolatum, is best known for its symbiotic relationship with various siricid wood wasp species. In this study, the relationship between isolates of A. areolatum associated with two wood wasp species, Sirex noctilio and S. juvencus, are considered to identify...

Three species of exotic bark beetles, Hylastes angustatus, Hylurgus ligniperda and Orthotomicus erosus, occur on Pinus spp. in South Africa. Although these bark beetles have been reasonably intensively studied in South Africa, little is known regarding their associated fungi. In this study, 1558...

Isolations for blue-stain fungi were made from Hylastes ater, H. opacus, Hylurgops palliatus and Tomicus piniperda trapped in Pinus sylvestris billets. Five Leptographium spp. including 1 of unknown identity and 2 apparently undescribed Graphium spp. were isolated. One of the Leptographium spp....
