20.500.12556/DiRROS-30181 Confirming the presence of the invasive moth Ypsolopha chazariella (Lepidoptera: Ypsolophidae) in Siberia insights into the species biology and molecular genetics Ypsolopha chazariella (Mann, 1866) (Lepidoptera: Ypsolophidae) is a European moth species known to feed on Tatar maple (Acer tataricum L.), a tree species naturally present in Europe. In 2009–2023, characteristic damage provisionally attributed to Y. chazariella was documented in botanical gardens in Novosibirsk, Krasnoyarsk (Russia, Siberia), suggesting the occurrence of a new pest. In 2024, significant damage was observed in an arboretum in Krasnoyarsk (Eastern Siberia) on the introduced A. tataricum and East Asian Acer ginnala Maxim. Two adult specimens of Y. chazariella were reared from larvae collected on both maple hosts and identified using genital morphology. Seven DNA barcodes (mitochondrial COI gene fragments) obtained for the specimens from Krasnoyarsk (6 specimens) and Novosibirsk (1) analyzed together with available DNA barcodes from Belarus and Finland showed low intraspecific divergence (0.7%). Among six haplotypes detected, two of them were formed solely by the Siberian specimens connected with the haplotypes recorded in Europe through two mutation steps. Genetic distance analyses revealed clear differentiation from closely related species (Y. dorsimaculella, Y. arizonella, and Y. rubrella) in the Barcode of Life Database (BOLD), with pairwise minimal distances between Y. chazariella and above-mentioned species ranging from 10.6% to 12.9%. A brief species essay was compiled, providing a note on the species biology, molecular genetics, present species range, and impact in ornamental plantings. Photographic documentation includes characteristic feeding damage and images of adult moths, along with detailed illustrations of male and female genitalia. alien pest moth maple Acer tataricum damage DNA barcoding Asian Russia tujerodni škodljivci vešča javor Acer tataricum poškodbe drevja črtno kodiranje DNK Rusija true false true Angleški jezik Slovenski jezik Znanstveno delo 2026-06-16 13:51:20 2026-06-16 13:51:20 2026-06-17 03:46:52 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 16. 6. 2026; str. 1177-1193 Vol. 11 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*4 2412-1908 10.5281/zenodo.17529793 281813507 https://zenodo.org/records/17529793 1 b2c8b4b9-6979-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45688 Kirichenko_et_al_final.pdf Kirichenko_et_al_final.pdf 1 876317FFE58A9C0DC66D30ECE27CA86B 8e61fa152e3ce8905c505b664d68717f7aaf850c52ded0dc8b90694c5da8baf8 bfbb6ca2-6979-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45689 Gozdarski inštitut Slovenije 0 0 0
