Distribution of conifer beetles (Scolytidae, Curculionidae, Cerambycidae) and wood nematodes (Bursaphelenchus spp.) in European and Asian Russia

Abstract

The objective of this paper is to compare, between regions of Russia, conifer beetles found in Scolytidae, Curculionidae and Cerambycidae. Of the 220 species of bark beetles which were found in Russia, 108 species are associated with conifers. Sixty‐three species of bark beetles are established in the European region of Russia and 94 species have been found in the Asian region. In Western Siberia 50 species are found. Eastern Siberia — 54 species, Russian Far East — 79 species. Forty‐nine species of bark beetles (such as Dendroctonus micans, Ips duplicatas, I. sexdentatus and I. typographus) are widely distributed throughout all Russian regions. There are 12 species of Pissodes found in all or various parts of Russia. Six weevil species (Pissodes gyllenhali, P. harcyniae, P. castaneus, P. pini, P. piniphilus and P. validirostris) are found throughout Russia and Western Europe. Five weevil species have only been found in the Asian region of Russia (Pissodes cembrae, P. insignitus, P. irrogatus, P. nitidus, P. nemorensis). Information concerning surveys of Russian conifer forests for wood nematodes, Bursaphelenchus spp., and their vectors is analysed. There is no evidence that B. xylophilus has ever occurred in Russia. Only B. mucronatus has been found. Six species of Monochamus beetles are found in Russia.
