Тест был направлен на выявление независимой от переносчика специфичности нематод к разным растениям. Эксперимент проводили на саженцах в закрытом грунте в лабораторных условиях. Изоляты нематод хранились в банке живых культур Зоологического института РАН. Перед постановкой теста черви были размножены в стерильной культуре гриба Botrytis cinerea. В качестве инокулята для заражения саженцев использовали 200 особей нематод одного вида разных стадий развития на растение. Эксперимент проводился при температуре 21–23 °C на протяжении 45 дней. Параметр успешного размножения – превышение финальной численности нематод над инокулюмом. Вид B. willibaldi продемонстрировал выживаемость на всех трех видах экспериментальных растений, однако превышение численности нематод по сравнению с инокулюмом не было зафиксировано. Вид B. ulmophilus выжил на P. abies и A. platanoides. На F. excelsior вид B. ulmophilus не выжил. Вид B. michalskii через 45 дней после инокуляции не обнаружен ни в одном из зараженных растений. Это свидетельствует о том, что данный вид нематод не способен выживать на представленных видах растений. Вероятность возникновения независимой от переносчика специфичности трех представленных видов нематод к протестированному кругу растений является низкой.</p></abstract><trans-abstract xml:lang="en"><p>   The specificity of three species of nematodes of the genus Bursaphelenchus: B. willibaldi (Fungivorus), B. ulmophilus (Hoffmanni), B. michalskii (Eggersi) to three species of woody plants: Picea abies, Acer platanoides, Fraxinus excelsior was tested in laboratory conditions. The test was aimed at identifying the vector-independent specificity of nematodes to host plants. The experiment was conducted on indoor seedlings under laboratory conditions. Nematode isolates were stored in the live culture bank of the Zoological Institute of the Russian Academy of Sciences. The worms were cultured in a sterile culture of the fungus Botrytis cinerea before the test was set up. As an inoculum for infecting the seedlings, 200 individuals of the same species of nematodes at different developmental stages were used per plant. The experiment was conducted at 21–23 °C for 45 days. The parameter for successful reproduction is the excess of the final nematode population over the inoculum. The species B. willibaldi demonstrated survival on all three experimental plant species, but no excess of nematodes compared to the inoculum was recorded. B. ulmophilus survived on P. abies and A. platanoides. B. ulmophilus was not detected on F. excelsior. B. michalskii was not detected in any of the infested plants 45 days after inoculation. This indicates that this nematode species is not able to survive on the plant species represented. The probability of vector-independent specificity of the three submitted nematode species to the tested range of plants is low.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>род Bursaphelenchus</kwd><kwd>специфичность</kwd><kwd>фитотест</kwd><kwd>популяция</kwd><kwd>патоген</kwd><kwd>инокуляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>genus Bursaphelenchus</kwd><kwd>host range</kwd><kwd>phytotest</kwd><kwd>population</kwd><kwd>pathogen</kwd><kwd>inoculation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование поддержано грантом Российского научного фонда, проект № 24-16-00092 «Взаимосвязи насекомых-вредителей и патогенных организмов и ответные реакции древесных растений северо-запада европейской части России: мониторинг и методы контроля плотности популяций вредителей и патогенов».
