Factors that influence fungal communities in ambrosia beetle mycangia are poorly understood. The beetle that is responsible for spreading laurel wilt in SE USA, Xyleborus glabratrus, was examined at three sites along a 500 km N–S transect in Florida, each populated by host trees in the Lauraceae. Fungal phenotypes were quantified in mycangia of individual females that were collected from a site in Miami-Dade County (MDC), 25.8N, with swamp bay (Persea palustris), one in Highlands County (HC… 

Presence and Prevalence of Raffaelea lauricola, Cause of Laurel Wilt, in Different Species of Ambrosia Beetle in Florida, USA

Ambrosia beetle species that have been associated in Florida with Raffaelea lauricola, the primary symbiont of Xyleborus glabratus Eichhoff and cause of laurel wilt, are summarized and the potential effects of R. luricola's promiscuity are discussed.

New Raffaelea species (Ophiostomatales) from the USA and Taiwan associated with ambrosia beetles and plant hosts

The results of this study show that Raffaelea and associated ophiostomatoid fungi have been poorly sampled and that future investigations on ambrosia beetle mycosymbionts should reveal a substantially increased diversity.

Response of swamp bay, Persea palustris, and redbay, P. borbonia, to Raffaelea spp. isolated from Xyleborus glabratus

Compared the response of two laurel wilt suspects to five species, another undescribed Raffaelea sp.

Laurel Wilt in Natural and Agricultural Ecosystems: Understanding the Drivers and Scales of Complex Pathosystems

The rapid spread of laurel wilt in the United States is due to an efficient vector, X. glabratus, and the movement of wood infested with the insect and pathogen, which severely constrain the disease’s management in forest ecosystems and avocado production areas.

No rest for the laurels: symbiotic invaders cause unprecedented damage to southern USA forests

It is proposed that a single founding event is responsible for the laurel wilt epidemic in the United States and that numerous native shrub and tree species in the Lauraceae are susceptible and threatened in the Western Hemisphere.

Partnerships Between Ambrosia Beetles and Fungi: Lineage-Specific Promiscuity Among Vectors of the Laurel Wilt Pathogen, Raffaelea lauricola

Yeasts (Ascomycota, Saccharomycotina) were found consistently in the mycangia of the examined beetles, and distinct, putatively co-adapted populations of these fungi were associated with each beetle species.

Flexibility in the ambrosia symbiosis of Xyleborus bispinatus

Xyleborus bispinatus could exchange its fungal symbionts, survive, and reproduce on different fungal diets, including known fungal associates and phylogenetically distant fungi, which are plant pathogens and primary symbiont of other invasive ambrosia beetles.

Genetic Variation in Native Populations of the Laurel Wilt Pathogen, Raffaelea lauricola, in Taiwan and Japan and the Introduced Population in the United States.

It is suggested the importance of preventing a second introduction of R. lauricola to the United States, which could introduce the opposite mating type and allow for genetic recombination.

Raffaelea lauricola (laurel wilt).

Abstract Laurel wilt is responsible for the death of hundreds of millions of redbay (Persea borbonia sensu lato) trees throughout the southeastern USA, and the disease is also having significant

Ophiostomatalean fungi associated with wood boring beetles in South Africa including two new species

Five species of ophiostomatalean fungi associated with ambrosia beetles occurring in a native forest area in South Africa were isolated and identified using both morphological characters and DNA sequence data.

Isolations from the redbay ambrosia beetle, Xyleborus glabratus, confirm that the laurel wilt pathogen, Raffaelea lauricola, originated in Asia

The results support the hypothesis that R. lauricola was introduced into the USA in the mycangium of the redbay ambrosia beetle, Xyleborus glabratus, which is native to Asia and suggest that the X. glabRatus population established in USA originated in another part of Asia.

Quantification of propagules of the laurel wilt fungus and other mycangial fungi from the redbay ambrosia beetle, Xyleborus glabratus.

The laurel wilt pathogen is a fungal symbiont of the redbay ambrosia beetle, Xyleborus glabratus, which was believed to have brought R. lauricola to the southeastern United States and was isolated in the highest numbers, up to 30,000 CFU/beetle.

Xyleborus glabratus, X. affinis, and X. ferrugineus (Coleoptera: Curculionidae: Scolytinae): Electroantennogram Responses to Host-Based Attractants and Temporal Patterns in Host-Seeking Flight

An electroantennography (EAG) method developed for assessment of olfactory responses in ambrosia beetles is presented and used to quantify EAG responses of X. glabratus, X. affinis, and X. ferrugineus to volatiles from three host-based attractants.

Lateral transfer of a phytopathogenic symbiont among native and exotic ambrosia beetles

Results indicate flexibility in the lateral transfer of a non-native ambrosial fungus to other ambrosia beetles, and for the first time documents the transmission of a laterally transferred phytopathogenic symbiont by new ambrosian beetle species.

Raffaelea lauricola , a new ambrosia beetle symbiont and pathogen on the Lauracea .

An undescribed species of Raffaelea earlier was shown to be the cause of a vascular wilt disease known as laurel wilt, a severe disease on redbay (Persea borbonia) and other members of the Lauraceae

Phylogeny of ambrosia beetle symbionts in the genus Raffaelea.

Strong host preference of ectomycorrhizal fungi in a Tasmanian wet sclerophyll forest as revealed by DNA barcoding and taxon-specific primers.

It is demonstrated that strongly host-preferring, though not directly specific, ECM fungi may dominate the below-ground community, similar to that in the Holarctic realm.

New combinations in Raffaelea, Ambrosiella, and Hyalorhinocladiella, and four new species from the redbay ambrosia beetle, Xyleborus glabratus

Phylogenetic analyses of LSU rDNA sequences placed these mycangial inhabitants and other species of Raffaelea, as well as some species of Ambrosiella associated with ambrosia beetles, into a monophyletic, asexual clade within Ophiostoma.

Abundance and dynamics of filamentous fungi in the complex ambrosia gardens of the primitively eusocial beetle Xyleborinus saxesenii Ratzeburg (Coleoptera: Curculionidae, Scolytinae).

The data suggest that two mutualistic, several commensalistic and one to two pathogenic filamentous fungi are associated with X. saxesenii, which cultivates fungi in tunnels excavated within dead trees.

An Uncertain Future for American Lauraceae: A Lethal Threat from Redbay Ambrosia Beetle and Laurel Wilt Disease (A Review)

The current understanding of the insect vector, the mycopathogen, and the susceptible host tree species are summarized and elements of disease management and limitations are addressed with current detection methods for redbay ambrosia beetle, which rely on manuka oil lures.
