The smaller European elm bark beetle, Scolytus multistriatus, has been the primary vector of the Dutch elm disease fungus, Ophiostoma novo-ulmi, in elm trees in Colorado since 1948. An exotic from Asia, the banded elm bark beetle, Scolytus schevyrewi, was found in Siberian elm, Ulmus pumila, in Colorado in April of 2003; this was the first report of S. schevyrewi in North America. S. schevyrewi is now found throughout much of Colorado and in at least 21 other states. The similarities in breeding and feeding habits between S. schevyrewi and S. multistriatus have raised concerns about the ability of S. schevyrewi to serve as a vector for O. novo-ulmi. The objective of this preliminary study was to determine if O. novo-ulmi could be isolated from adult S. schevyrewi emerging from diseased elm trees. S. schevyrewi and S. multistriatus were allowed to infest diseased stem segments of American elm, Ulmus americana. The infested stem segments were caged and isolations were made from the adult brood that emerged. O. novo-ulmi was isolated from most of the adults of both beetle species, showing that S. schevyrewi could acquire the pathogen as effectively as S. multistriatus. Future studies are needed to determine if S. schevyrewi can effectively transmit the pathogen to healthy trees.

The City

The first outbreak of Dutch elm disease in Manitoba was recorded in 1975 in Brandon, Selkirk, and Winnipeg (Hildahl 1977). The primary vector of the disease in Canada is the native elm bark beetle, Hylurgopinus rufipes (Eichh.). The smaller European elm bark beetle, Scolytus multistriatus (Marsh.), is considered the primary vector in most of the United States. In Canada, the latter species occurs throughout most of southern Ontario, parts of south-central Quebec, and has been recorded in New Bmnswick (Sterner et al. 1976).

AbstractTwig-feeding injuries by S. multistriatus in juvenile white (or American) elms occurred primarily (61%) in the upper 1/3 of the crowns. Preferred feeding sites were crotches formed by the previous year's and current year's twig growth (both spring and summer) and by leaf petioles from current year's twig growth (summer only). An index of twig feeding appeared to reflect S. multistriatus population trends and was closely correlated with Dutch elm disease rates in Syracuse, N.Y., from 1978 to 1982. Twig-feeding indices and catches on sticky traps baited with S. multistriatus pheromone were generally correlated, but disparate when competing natural pheromone sources were abundant. Twig sampling indicated that S. multistriatus populations and disease rates were reduced by mass-trapping and trap-tree techniques. The twig-sampling method presented appears to be useful in predicting Dutch elm disease rates and assessing the effectiveness of measures to control its beetle vector.

Current Incidence

Although many possible vectors of the Dutch elm disease, Ceratocystis ulmi (Buism.) C. Moreau, have been listed by Collins et al. (1936) and others, only two, Scolytus multistriatus (Marsh.), the European elm bark beetle, and Hylurgopinus rufipes (Eichh.), the native elm bark beetle, are known to transmit the disease with any regularity. In this capacity alone thcse two species of beetles are important pests of elm. The persistent spread of the Dutch elm disease in southern Ontario (Hord and Quirke, 1955) made it imperative that adequate surveys be maintained to indicate yearly changes in the occurrence of the introduced vector, and to ascertain more precisely the distribution of the native vector relative to the distribution of elm in Ontario. Consequently the Forest Insect Survey of the Forest Insect Laboratory, Sault Ste. Marie, intensified its elm bark beetle program in 1956, and from then to 1959, 138 positive samples of these two scolytid beetles have been received. An analvsis of these records and their relationihip to the current incidence of the Dutch elm disease in Ontario are presented in this paper.

Водородная связь (Н-связь) обеспечивает необходимую гибкость и устойчивость биологических систем, в том числе древесины. Для исследования энергии и концентрации Н-связей в древесине возможно применение ИК-спектроскопии. В этом случае судить о природе гидроксильных групп можно опираясь на величины длин и энергий Н-связей, известных для водородных связей в целлюлозе, лигнине и других компонентах древесины, которые были исследованы ранее [Иванов-Омский и др., 2017; Иванова и др., 2016]. Особенный интерес представляет решение задачи об изменении прочности и иных свойств древесины при отмирании дерева в случае повреждения биологическими агентами. В данном исследовании поставлена задача – исследовать влияние повреждений короедов на структуру водородных связей древесины. Объектом исследования выбран вяз Ulmusglabra Huds, заселённый струйчатым заболонником. Этот короед является вектором распространения голландской болезни ильмовых в Санкт-Петербурге. Срезы для спектрального анализа взяты с поверхности заболони вяза, заселённого короедом. Полученные результаты показали, что на повреждённых заболонником участках происходит разрушение наиболее сильной межмолекулярной связи, обеспечивающей соединение молекул целлюлозы и, соответственно, прочность ствола. Увеличивается и концентрация внутримолекулярных связей, что может означать принципиальные изменения в водном обмене клеток древесины, связанные с разрушением аквапоринов. Это явление может быть связано с ответной реакцией вяза на нарушение движения растворов по сосудам при механическом разрушении древесины во время питания короедов и/или попаданием ферментов их слюнных желёз, амилазы или других карбогидраз. Не исключено попадание в древесину и других ферментов, например продуцируемых симбионтами короедов. Hydrogen bond (H-bond) provides the necessary flexibility and stability of biological systems, including wood. It is possible to use Infrared spectroscopy to study the energy and concentration of H-bonds in wood. In this case, it is possible to assess the nature of the hydroxyl groups based on the lengths and energies of H-bonds, known for hydrogen bonds in cellulose, lignin and other wood components, which had been studied earlier [Ivanov-Omskiy et al., 2017; Ivanova et al., 2016]. Of special interest is the solution of the problem of changing the strength and other properties of wood when the tree dies in case of damage by biological agents. In this paper, the task was to study the effect of damage by bark beetles on the structure of hydrogen bonds of wood. The object of research was elm Ulmus glabra Huds infested by the European elm bark beetle Scolytus multistriatus. This bark beetle is the vector of Dutch elm disease in St. Petersburg. Sections for spectral analysis are taken from the surface of the elm sapwood inhabited by bark beetle. The obtained results showed that on the sites damaged by the sapwood, the strongest intermolecular bond (which binds the cellulose molecules together and ensures the strength of the trunk) breaks down. The concentration of intramolecular bonds also increases. This means a fundamental change in the water metabolism of wood cells, associated with the destruction of aquaporins. This phenomenon may be related to the response of the elm to the violation of the movement of solutions through vessels during mechanical destruction of wood during the feeding of bark beetles and/or the ingestion of enzymes from their salivary glands, amylase or other carbohydrases. It is also possible that other enzymes (such as those produced by the beetles’ symbionts) come into contact with wood.
