“…Similar symbiotic associations have been extensively reported among microbial associates and wood-boring beetles (Cardoza et al 2006, Adams et al 2011, Six et al 2011, Sun et al 2013. For example, mycangial symbiotic fungi enhance the diet of Dendroctonus frontalis larvae by contributing to the acquisition of N and P (Ayres et al 2000); the yeasts isolated from Phoracantha semipunctata feeding on Eucalyptus could degrade saccharose, maltose, amidon, and pectin (Dowd 1992).…”

Abstract. Invasive pathogen-insect symbioses have been extensively studied in many different ecological niches. Whether the damage of symbioses in different introduced regions might be influenced by other microorganisms has, however, received little attention. Eight years of field data showed that the varied levels of the nematode and beetle populations and infested trees of the invasive Bursaphelenchus xylophilus-Monochamus alternatus symbiosis were correlated with patterns in the isolation frequencies of ophiostomatoid fungi at six sites, while the laboratory experiments showed that the nematode produced greater numbers of offspring with a female-biased sex ratio and developed faster in the presence of one native symbiotic ophiostomatoid fungus, Sporothrix sp. 1. Diacetone alcohol (DAA) from xylem inoculated with Sporothrix sp. 1 induced B. xylophilus to produce greater numbers of offspring. Its presence also significantly increased the growth and survival rate of M. alternatus, and possibly explains the prevalence of the nematode-vector symbiosis when Sporothrix sp. 1 was dominant in the fungal communities. Studying the means by which multispecies interactions contributed to biogeographical dynamics allowed us to better understand the varied levels of damage caused by biological invasion across the invaded range.

“…The patterns of continued, complex, and increasingly rapid rates of introduction are not unique to S. noctilio but, unfortunately, represent a general trend for many invasive species (41,84,87,93,97). All findings indicate that we face a future with much greater pressure due to a diversity of pests in natural woody ecosystems and in planted forests.…”

The Sirex woodwasp, Sirex noctilio, and its fungal mutualist, Amylostereum areolatum, together constitute one of the most damaging invasive pests of pine. Despite a century of research and well-established management programs, control remains unpredictable and spread continues to new areas. Variable success in managing this pest has been influenced by complex invasion patterns, the multilayered nature of biological interactions, the varying local ecologies, and microevolutionary population processes in both the biocontrol organisms and in the wasps. Recent research findings are challenging the historical perspectives on methods to manage the Sirex woodwasp, calling for management programs to incorporate the variable local dynamics affecting this pest complex. In this regard, the Sirex woodwasp provides a superb model to illustrate the need for a different approach to develop efficient and sustainable management tools to deal with the growing and global nature of pest invasions in forests and plantations.

“…Their increased prevalence has often been associated with activities that facilitate encounters of new or naïve host trees. Anthropogenic expansion of the geographic ranges of the pathogens and their vectors are responsible for most of the disease outbreaks (147), and movement of infested materials via international trade may be most important (59).…”

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

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. The order Coleoptera contains more species than any other or...
