Аннотация: Совместное культивирование офиостомовых грибов на агаровой среде с водным экстрактом луба пихты показало, что грибы-ассоцианты черного пихтового усача из рода Ophiostoma могут ограничивать рост и развитие гриба Ophiostoma aoshimae, связанного с уссурийским полиграфом на пихте сибирской. Взаимоотношения изолятов O. aoshimae и Leptographium sibirica при совместном росте на агаровой среде указывают на возможность сосуществования этих грибов в природе.

A new Leptographium species from Russia
[Text] / K. . Jacobs [et al.] // Mycol. Res. - 2000. - Vol. 104. - P1524-1529, DOI 10.1017/S0953756200002689. - Cited References: 39

Аннотация: Species of Leptographium are well-known inhabitants of conifers in the Northern Hemisphere, in which they cause a blue-stain. They are also known to be associated with insects, especially bark beetles (Coleoptera: Scolytidae). Surveys of dying stands of Siberian fir (Abies sibirica) have resulted in the consistent isolation of an unknown Leptographium from the galleries of the fir sawyer beetle, Monochamus urussovi (Coleoptera: Cerambycidae). This fungus is responsible for the blue-stain in living trees. Comparison with known species of Leptographium led to the conclusion that it had not been previously described, and the name Leptographium sibiricum sp. nov, is introduced here.

Аннотация: Effect of tannin and non-volatile components of lesion resin on the growth of blue-stain fungi - Ceratocystis laricicola, C. polonica, Ophiostoma minus, Leptographium sp. and Ophiostoma sp. - the primary invaders of conifers in Siberia (Russia), has been studied. The fungi under study exhibited tolerance to plant's defensive substances in bioassays. The cultures of Leptographium sp., C. polonica, and Ophiostoma sp. proved to be the most tolerant to tannin. In the range between 0.05 and 0.15% tannin concentration their growth tended to stabilize. Less tolerant to tannin were C. laricicola and O. minus. With an increase in tannin concentration their biomass gradually decreased. The fungi more tolerant to tannin regulated the medium pH about 5.0 and higher, white the species which were less tolerant preferred lower pH values. Lesion resins of conifers differed in their inhibitory effect on fungal growth. Fir resin had the greatest inhibitory effect of all the conifer resins tested, causing reduction to 50-60% in fungal growth. When fungi were grown on the resin of any other conifer, the reduction in the linear growth rate did not exceed 20 to 30%. The assumption that fungi are more tolerant to the resin of a host plant than to that of a non-host plant has not been confirmed.

Аннотация: Effect of defoliation on resistance response of Siberian fir, Abies sibirica Ledeb., to fungal inoculation was investigated within three even-aged fir stands damaged by Siberian moth, Dendrolimus superans sibiricus Tschetw., and located in the Krasnoyarsk Territory (Central Siberia). Histological changes in tissues, accompanying the resistance response were examined in 30 fir trees (90-130 years old) of different defoliation degree (50, 75, 100 %) six weeks after single inoculation with Leptographium sp, vectored by Monochamus urussovi Fisch. (Coleoptera: Cerambycidae). It was recorded that the rate and intensity of defence response of phloem and xylem tissues to inoculation as well as percent of trees infested by the insect-vector differed significantly in dependence of defoliation degree. Trees of 50 percent defoliation significantly differed from trees of more severe defoliation in all parameters of defence response and percentage of colonisation by the beetle. The trees defoliated to 75 and 100% did not differ significantly in defence response activity and the number of the trees attacked by M. urussovi Strong difference in resistance to inoculation and colonisation by the beetle was recorded between trees defoliated in the current year and in the previous year. All infested by M, urussovi trees were characterised by the epidemic level of frequency of blue-stain fungi associated with this insect. The tendency was recorded to a decreased frequency of the pathogenic Ophiostoma sp. and a more frequent occurrence of the saprophyte O. curvicollis in trees defoliated in previous year which lost ability to defend against wounding and fungal infection.

Перенос офиостомовых грибов уссурийским полиграфом Polygraphus proximus(Coleoptera, Scolytidae) в Сибири
[Текст] : материалы временных коллективов / Н. В. Пашенова [и др.] // Известия Санкт-Петербургской лесотехнической академии. - 2012. - Вып. 200. - С. 114-120. - Библиогр. в конце ст.
Аннотация: Введение. В природном ареале (российский Дальний Восток, Китай и Япония) уссурийский полиграф распространяет офиостомовые грибы, поражающие сосудистые ткани хвойных. Ophiostoma aoshimae и O. subalpinum указаны, как наиболее важные фитопатогенные ассоцианты вредителя. В последние годы инвазийные популяции полиграфа отмечены в Сибири. Цель данной работы заключалась в изучении видового состава офиостомовых грибов, связанных с уссурийским полиграфом в двух популяциях вредителя в Красноярском крае и Томской области. Материалы и методы. Сбор материала в очагах размножения полиграфа проводили в июне 2010 г. (Красноярский край) и апреле 2011 г. (Томская обл.). Образцами являлись высечки из стволов пихты сибирской, содержащие ходы вредителя. Рост и развитие грибов наблюдали в образцах, помещенных во влажные камеры. Офиостомовые грибы изолировали в чистую культуру, стерильно перенося споровый материал на агаровую среду. Идентификацию грибов выполняли по морфологическим признакам. Частоту встречаемости оценивали по отношению числа образцов с офиостомовыми грибами к общему количеству образцов в исследуемых партиях. Результаты. В изучаемых популяциях полиграфа общая частота встречаемости офиостомовых грибов варьировала от 76 до 100 %. Из пяти обнаруженных видов наиболее часто регистрировались грибы Ophiostoma sp. А (48–100 %) и Leptographium sp., (около 50 %). Встречаемость трех остальных видов (Ophiostoma sp. B, Graphium sp. 1 и Graphium sp. 2) была менее 50 %. Морфологические исследования показали высокую вероятность принадлежности Ophiostoma sp. А и Ophiostoma sp. B к видам O. aoshimae и O. rectangulosporium, соответственно. Leptographium sp. проявил сходство с видом L. sibirica. Обсуждение. Грибы O. aoshimae и O. rectangulosporium описаны как ассоцианты уссурийского полиграфа в Японии, но не были известны в Сибири. L. sibirica, напротив, описан как типичный обитатель ходов Monochamus urussovi (Fisch.) на пихте сибирской, но сведения об его связи с полиграфом отсутствуют. Обсуждается возможность формирования нового комплекса офиостомовых грибов, связанного с полиграфом в Сибири, как результат сочетания видов, занесенных вредителем из Дальневосточного региона, и аборигенных сибирских грибов. Вспышечная активность proximus в лесах Сибири указывает на необходимость изучения связанных с ним грибов и оценки их агрессивности в отношении местных хвойных пород.

Ophiostomatoid Fungi Associated with the Four-Eyed Fir Bark Beetle on the Territory of Russia

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.
