Аннотация: Ceratocystis laricicola and C. polonica are fungal symbionts of bark beetle species of the genus lps that attack species of Larix and Picea, respectively, across Eurasia. Earlier studies found that these fungal species were morphologically identical, had similar isozymes patterns, and had identical internal transcribed spacer (ITS) sequences of the rDNA operon. We analyzed 27 isolates from Europe, southwestern Siberia (Russia) and Japan, representing the known geographic ranges of the two species. Phylogenetic analysis of the DNA sequences of a portion of the MAT-2 idiomorph showed these species to be distinct, with the Japanese isolates of C. laricicola having a sequence slightly different (5 bp) from those of the Russian and European isolates of C. laricicola. Sexual compatibility tests showed full interfertility among isolates of C. polonica from Europe, Russia and Japan, but isolates of C. polonica were not fully interfertile with isolates of C. laricicola. A Russian and a European isolate of C. laricicola mated with each other but not with the Japanese isolates of C. laricicola. Mature L. sibirica and P. obovata were inoculated with isolates of C. laricicola and C. polonica from Europe, Russia, and Japan, and measurement of lesions in the inner bark/cambium region demonstrated strong host specialization. The data suggest that the two fungal species are very closely related and are distinguished primarily by their physiological specialization to the hosts of their bark beetle vectors.

Аннотация: В работе приведены результаты датировки начала инвазии уссурийского полиграфа Polygraphus proximus Blandford (Coleoptera, Curculionidae, Scolytinae) на территорию Томской обл. Датировку производили методами дендрохронологии на материале, собранном в пяти погибших от полиграфа древостоях в окрестностях Томска. Наиболее ранний случай гибели дерева, на котором найдены ходы полиграфа, датирован 2000 г. Для достижения численности короедов, необходимой для преодоления защитных свойств дерева, инвайдеру требуется не менее 5–6 лет. Таким образом, время его инвазии в Томскую обл. необходимо отнести к середине 1990-х гг.

In Russia, beetles were collected by S. Krivets and I. Kerchev (West Siberia and Primorsky Krai); G. Yurchenko (Khabarovsk Province); Yu. Gninenko (Sakhalin Island); K. Tchilahsayeva and L. Seraya (Moscow Province and suburbs); and D. Demidko (Khakasiya). H. Masuya kindly collected beetles in Japan.

Аннотация: 1 The four-eyed fir bark beetle Polygraphus proximus Blandf., native in Far Eastern Eurasia and nearby islands, is an invasive pest of fir trees in Siberian and European parts of Russia. Its invasion has been overlooked and was only finally appreciated in 2008. 2 Subsequently, the scale and area of damage to the forests has increased catastrophically. Thus, extensive monitoring and population control are required to localize and stop any further spread of the invasion. 3 We used mitochondrial DNA markers to analyze the genetic diversity and population structure of invasive and aboriginal populations of P. proximus, aiming to establish the main sources and corridors of its spread and to infer the history of colonization. 4 Eighteen haplotypes clustered in five groups were identified. The aboriginal populations had the highest degree of haplotype variability, including almost all haplotypes found in the areas of invasion. The Siberian introduced populations had a sufficient reduction of genetic variation, and a strong geographical partitioning. The European populations mostly had the same haplotypes as the invasive Siberian populations. 5 The results of the present study support the scenario of P. proximus spreading from the Far East of Russia westward via timber transport along the major Russian railway network.

Аннотация: The study is aimed at investigation of ophiostomatoid fungi, associated with the four-eyed fir bark beetle (Polygraphus proximus Blandford, Coleoptera, Curculionidae)—an invasive pest of Siberian fir Abies sibirica. In the Russian Far East, eight fungal species are associated with this bark beetle. All of these fungi (except Leptographium taigense and Grosmannia europhioides) were brought by P. proximus to its secondary range (Southern Siberia and Moscow oblast). In the secondary range, a complex of ophiostomatoid fungi connected with P. proximus consists mainly of the Far Eastern species adapted to new habitats. Phytopathogenic activity of the fungi associated with bark beetle was studied. G. aoshimae and Ophiostoma nikkoense demonstrated high phytopathogenic activity after inoculation into phloem of Siberian fir. The culture of G. aoshimae and O. subalpinum produced extensive necroses in stems of Siberian larch Larix sibirica. In general, G. aoshimae is the main fungal associate of P. proximus, considering the frequency and stability of its occurrence in samples, as well as its aggressiveness toward coniferous species of Southern Siberia. It demonstrated high aggressiveness toward Siberian fir and Siberian larch; Scots pine Pinus sylvestris is also susceptible to this fungus. Siberian spruce Picea obovata and Siberian pine Pinus sibirica are resistant. There is a high possibility of P. proximus mycobiota enrichment with a complex of fungi connected with fir sawyer beetle Monochamus urussovi Fisch., an aboriginal pest of fir in Siberia. © 2018, Pleiades Publishing, Ltd.
