“…After consideration of the biology of nematodes associated with bark beetles, Polyanina et al [ 31 ] revealed several types of relations in the nematode–beetle–tree associations. Following this classification, several ecological groups of nematodes associated with bark beetles could be distinguished among the studied samples: obligatory ectophoronts, fungal and plant feeders ( Bursaphelenchus , Cryptaphelenchus , Aphelenchoides ); facultative phoronts and fungivores ( Laimaphelenchus ); facultative phoronts, bacterial and fungal spore feeders ( Diplogasteroides ); facultative phoronts and carnivores ( Micoletzkya ); gut bark beetles endoparasites ( Parasitorhabditis ); hemocoel parasites of larval insect stage ( Parasitaphelenchus ); hemocoel parasites of adult insect stage ( Deladenus and sphaerulariid nematodes).…”

Wood- and bark-inhabiting parasitic nematodes are of great economic importance. Nematodes can cause wilt diseases in conifers and deciduous trees. In 2014–2022, during nematology surveys conducted in different regions of Russia and Belarus, adults and dauer juveniles of nematodes were collected from wood, bark and beetle vectors. Using traditional morphological taxonomic characters integrated with molecular criteria, we identified in the studied samples the following nematode species: Aphelenchoides heidelbergi, Bursaphelenchus eremus, B. fraudulentus, B. michalskii, B. mucronatus, B. willibaldi, Deladenus posteroporus, Diplogasteroides nix and Laimaphelenchus hyrcanus, several unidentified species: Aphelenchoides sp.1 and sp.2, Cryptaphelenchus sp.1, sp.2 and sp.3, Laimaphelenchus sp.1, Micoletzkya sp.1, Parasitaphelenchus sp.1, Parasitorhabditis sp.1, three unidentified tylenchid nematodes and a new species, Bursaphelenchus zvyagintsevi sp.n. Morphological descriptions and molecular characterization are provided for B. zvyagintsevi sp. n. belonging to the Abietinus group and B. michalskii belonging to the Eggersi group. Findings of Aphelenchoides heidelbergi, Bursaphelenchus eremus, B. michalskii, Deladenus posteroporus, Diplogasteroides nix and Laimaphelenchus hyrcanus are new records for Russia. Phylogenetic positions of studied species were reconstructed using D2–D3 expansion segments of 28S rRNA gene sequence analysis. The data obtained in this study may help to detect the refugia of opportunistic plant pests and find possible native biocontrol nematode agents of insect vectors causing diseases.

“…in a single tree. Several insect species can carry Bursaphelenchus nematodes acting as vectors, mainly longhorn beetles (Cerambycidae), bark beetles (Curculionidae-Scolytinae), and jewel beetles (Buprestidae) [8,70,91,92]. For example, B. mucronatus was found to be associated with Ips sexdentatus Börner 1776, while B. sexdentati was associated with Orthotomicus erosus Wollaston 1857, Acanthocinus aedilis Linnaeus 1758, and Arhopalus rusticus Linnaeus 1758 [93].…”

In the context of plants or plant products protection by harmful organisms, measures have been taken by EU countries in order to prevent their introduction and establishment into the EU, and also limit their expansion in case they do enter. Such a case is Bursaphelenchus xylophilus (Parasitaphelenchidae, Nematoda), already recorded in Portugal and Spain. So, Member States should take all the appropriate steps in order to monitor and confine if necessary susceptible plants and/or plant products. Such measures include annual surveys even in countries where pine wilt disease does not occur yet. Therefore, national survey programs are widely established, sampling and examining samples from pine trees showing suspicious symptoms that could potentially be attributed to B. xylophilus. In this direction, such a network has also been established in Greece collecting and examining wood samples nationwide. In total, 123 wood samples were collected from conifer trees of Northern and Central Greece. Though B. xylophilus was absent from all samples examined, four other Bursaphelenchus species were identified. In addition, other nematode taxa were also recorded, including several phytophagous, microbivorous as well as predatory nematode species. This highlights the fact that besides preventing the introduction of B. xylophilus in Greece, national survey programs can significantly contribute to and enhance our knowledge of the indigenous nematode species.
