“…The PSHB is capable of colonizing living tissues of angiosperm hosts, which may help explain the beetle's unique semiochemical ecology (Kendra et al, 2017). However, data of Li et al (2016) did not suggest that the beetle is an aggressive colonizer of living and healthy trees, since nearly all individuals were collected in that study from weak, diseased, or dead host plants. Cooperband et al (2017) identified two pheromone compounds, 2-heneicosanone and 2tricosanone, for the three members belonging to the E. fornicatus species complex present in North America.…”

“…For example, in the United States, camphor trees seemed to be more resistant to vascular wilt disease caused by Raffaelea lauricola, native to areas of the fungal host Xyleborus glabratus, than American species of Lauraceae (Fraedrich et al, 2014). Native Xyleborini in turn attack live exotic tree species as demonstrated in the case of Euwallacea perbrevis in Sri Lanka (mentioned as Xyleborus fornicatus, Danthanarayana, 1968;Walgama, 2012) or Euwallacea fornicatus (Coleoptera: Curculionidae: Scolytinae) in India (Mote and Tambe, 1991), China (Li et al, 2016), and in Vietnam (Anon., 2014). This phenomenon was also evident in other groups of ambrosia beetles; for example, Megaplatypus mutatus (Platypodinae) native to Argentina that causes serious wilting of exotic Casuarina cunninghamiana in Argentina and Populus spp.…”

This study examined the polyphagous shot hole borer (PSHB) Euwallacea fornicatus (Coleoptera; Scolytinae) native to Southeast Asia and concentrated on its wide host range in two of the invaded areas, California and Israel. Among the 583 examined tree species, 55.9% were characterized as “non-reproductive hosts” and only 13.8% were characterized as “reproductive hosts,” suitable for the E. fornicatus reproduction. Families that included ≥20 species and genera with ≥10 were considered for further analysis. The highest percentage of tree species suitable for reproduction was obtained for Salicaceae and Sapindaceae, whereas the lowest percentage of tree species belonging to this category were within the Rosaceae, Myrtaceae, and Magnoliaceae. The genera Acer, Quercus and Acacia displayed the highest percentage within the “reproductive host” category, with the former significantly higher from all seven of the studied genera. We found that all Brachychiton and Erythrina were attacked and none of the examined 20 Eucalyptus spp. were suitable for E. fornicatus reproduction. The results suggest discordance between host tree phylogeny and susceptibility to the E. fornicatus, indicating that trait correlation of susceptibility of different tree species to the E. fornicatus are the results of convergent evolution and not of a common descent. A theoretical model, suggesting the different possibilities of potential tree species becoming attractive or non-attractive to E. fornicatus attack, is described. It is suggested that the beetle reproduction success rate over a wide host range, as well as the long list of species belonging to the “non-reproductive host” category, is the outcome of interactions between the beetle fungal symbiont, F. euwallaceae, and sapwood of the attacked tree. The model suggests that a tree selected by the E. fornicatus may fall in one of three groups, (i) those in which F. euwallaceae is unable to develop, (ii) those tree species that slow the development of the fungus, and (iii) those that enable F. euwallaceae to thrive. Hence, the host range suitable for beetle reproduction is determined by development of F. euwallaceae. In general, PSHB does not distinguish between host species of the “non-reproductive host” and “reproductive host” categories.

“…Fungi constitute a hyperdiverse kingdom representing an array of ecological lifestyles, including human pathogens, ectomycorrhizae, lichens, and many more (Burgess et al, 2006; Blackwell, 2011; Li et al, 2016; Medeiros et al, 2017; Crossay et al, 2018; Chang et al, 2019; Mujic et al, 2019).

Due to their fundamentally microscopic nature and their usually ephemeral reproductive structures (e.g., mushrooms, apothecia, etc.), the identification of fungi has historically been exceptionally difficult, relying on often artificial groupings based on limited morphological features. The advent and maturation of molecular approaches has revolutionized mycology; in the past two decades, a significant number of new orders, classes, and even phyla have been described (

“…In Asia, Euwallacea species usually infest dead or dying trees. There are only a few observations of damage on healthy living trees (Li et al ., 2014, 2016; Lynn et al ., 2020). In North America, five species of Euwallacea , E. fornicatus (Eichhoff), E. kuroshino Gomez and Hulcr, E. perbrevis (Schedl), E. interjectus (Blandford), and E. validus (Eichhoff), are established and some are becoming significant economic and ecological threats (O'Donnell et al ., 2016).…”

1 Extensive boring damage into trunks of living poplar trees in the urban forest of Shanghai, eastern China, was investigated in 2017. 2 In order to determine the taxonomic identity of the pest, we used morphological identification and sequenced mitochondrial COI gene. Based on both morphology and molecular data, it was concluded that the pest boring into the poplars was the ambrosia beetle Euwallacea interjectus (Blandford). 3 Its occurrence and damage on poplar across Shanghai were also investigated. In the Pudong District, a total of 104.52 ha of urban forest were investigated thoroughly, and 16.22% of surveyed forests were found to be infested. This insect species is an important native pest capable of causing damage across the Shanghai area. 4 Observations in the field suggested that the damage may be related to distance to water sources. Our statistical analysis confirmed this hypothesis, as the close distance to water bodies correlated with higher levels of damage. We conclude that E. interjectus prefers host trees stressed by an occasional excessive abundance of water, and acts as a parasite on living trees without killing them.
