“…Más aún si a ello se agrega la posibilidad actual de aplicar nuevas técnicas de apoyo, como por ejemplo, microscopía de alta resolución, o análisis moleculares de ADN a los especímenes en cuestión. Gadgil et al (2003) identificaron a Nectria fuckeliana C. Booth asociado a cancros en troncos de P. radiata, en Nueva Zelanda, lo que constituyó el primer reporte de este hongo afectando en forma natural a plantaciones de esta especie y también el primer reporte de este agente en el Hemisferio Sur . En base a las características observadas en cultivos, y utilizando como sustrato Agar Malta al 2%, Gadgil et al (2003) señalaron a Cylindrocarpon cylindoides var.…”

“…The disease is caused by Sporothrix nothofagi, which is transmitted by three species of ambrosia beetle, Platypus apicalis (Fig. 5I), P. gracilis and Treptoplatypus caviceps (formerly P. caviceps) (Platypodinae: Platypodini) (8,53). The beetles attack healthy, as well as unhealthy trees, and use an aggregation pheromone to initiate mass attacks (116).…”

“…In these cases, substantial damage on the host tree would not develop without repeated insult by both the beetles and fungi. In the most extreme examples, single infections by the symbionts are capable of causing serious damage or host death (51,53,123,133). In the latter situations, continued infestation by the beetle and multiple infections by the symbiont may occur, but are not needed to kill trees.…”

Destructive Tree Diseases Associated with Ambrosia and Bark Beetles: Black Swan Events in Tree Pathology?

et al. 2013

Diseases that are associated with ambrosia and bark beetles comprise some of the most significant problems that have emerged on trees in the last century. They are caused by fungi in the Ophiostomatales, Microascales and Hypocreales, and have vectors in the Scolytinae (ambrosia and bark beetles), Platypodinae (ambrosia beetles) and Hylesininae (bark beetles) subfamilies of the Curculionidae (Coleoptera) (73,102,144). Some of these problems, such as Dutch elm disease (DED), have a long history, have been extensively researched, and are fairly well understood (23,56,70,113,149,168,169). In contrast, other similar diseases developed recently and are poorly or partially understood (2,3,42,51,73,89,94,98,114,127,137,154,158, 164,165). Significant data gaps may exist for the ecology, epidemiology and management of the latter diseases.The emergence and unexpected importance of these tree diseases are discussed in thisarticle. An underlying factor in most of these interactions is the absence of a coevolved history between the so-called "naïve" or "new encounter" host trees and the pathogens and/or beetles (27,128,174). For the ambrosia beetles, these interactions are associated with susceptibility to what are typically benign fungi and atypical relationships with healthy trees (ambrosia beetles favor trees that are dead or stressed). Interestingly, the pathogens for both the ambrosia and bark beetle-associated diseases often have symbiotic relationships with the insects that are not based on phytopathogenicity. Some of the most alarming and damaging of these diseases are considered below as "black swan events" (155).Black Swans. Before 1697, improbable events and situations in Europe were known as "black swans" (at the time, all swans known to Europeans were white) (134). In that year, the black swan, Cygnus atratus, was discovered in Western Australia (38). Thereafter, "black swan" developed as a metaphor for a supposed impossibility that is contradicted with new information.For example, John Stuart Mill used black swan logical fallacy when identifying falsification, a key component in the scientific method (68).In a recent book, Taleb (155) developed Black Swan Theory (BST). Unlike the "black swan" to which Mill referred (68), BST focuses on unexpected events of large magnitude and consequence (155). Taleb (155) recognized such events in diverse fields including finance, history, science and technology. He suggested that black swan events: 1) have extreme impacts; 2) lie outside the realm of regular expectations (they are rare); and 3) are unpredictable.Although all ambrosia and bark beetle-associated diseases are not black swan events, several do fulfill the above criteria since they have large impacts, are uncommon surprises and are unpredictable (2,3,51,56,73,89,94,98,114,137,154,158, 164,165) (Table 1). They are typically understood and appreciated only with the benefit of hindsight and subsequent research.The Beetles and Beetle-associated Tree Diseases.

Redefining common endophytes and plant pathogens in Neofabraea, Pezicula, and related genera

et al. 2016

View full text Add to dashboard Cite

Species in Neofabraea, Pezicula, and related genera have been reported as saprobes, plant pathogens or endophytes from a wide range of hosts. The asexual morphs of Neofabraea and Pezicula had been placed in Cryptosporiopsis, now a synonym of Pezicula, while Neofabraea was also linked to Phlyctema. Based on morphology and molecular data of the partial large subunit nrDNA (LSU), the internal transcribed spacer region with intervening 5.8S nrDNA (ITS), partial β-tubulin region (tub2), and the partial RNA polymerase II second largest subunit region (rpb2), the taxonomy and phylogenetic relationships of these fungi were investigated. Five new species were described in Pezicula based on morphology, while a further eight unnamed phylogenetic lineages revealed further diversity in the genus. Based on these results, the generic concept of Neofabraea was also emended. Phlyctema, which was previously associated with Neofabraea, formed a distinct clade, separate from Neofabraea s. str. Two new neofabraea-like genera, Parafabraea and Pseudofabraea were proposed, along with one new combination in Neofabraea s. str. To stabilise the application of these names, an epitype was designated for Pe. carpinea, the type species of Pezicula, and for N. malicorticis, the type species of Neofabraea.
