20.500.12556/DiRROS-30184 First record of the invasive bark beetle Polygraphus proximus Blandford (Coleoptera: Curculionidae, Scolytinae) in the Republic of Kazakhstan The four-eyed fir bark beetle, Polygraphus proximus Blandford, 1894 (Coleoptera: Curculionidae, Scolytinae), is an aggressive invasive species originating from Far East. Over the past two decades, it distributed across Siberia, traversed the Urals and invaded some regions of the European part of Russia. In the secondary range, the pest kills heathy tree stands of Siberian fir, Abies sibirica Ledeb. (Pinaceae), both in native forests and man-made plantings, resulting in profound ecological and economic consequences. Here we report the first documented occurrence of this invasive pest in the Republic of Kazakhstan. Infested Siberian fir trees were discovered in the forest nearby Karaguzhikha village (East Kazakhstan Region), approximately 43 km away from Novoaleiskoye village (Altai Territory, Russia), where the pest was detected in 2016. The presence of trees colonized by the invasive pest and dead trees with specific symptoms in the examined forest stand suggest that P. proximus has likely been present in northeastern Kazakhstan for around a decade. The illustrations of affected habitat, male and female beetles and their morphological features are provided, and the early data on the damage caused by P. proximus and the potential for range expansions are discussed. The monitoring would be required to define the actual frontier of the pest distribution in Kazakhstan. Furthermore, it is imperative to alert the relevant authorities in Kazakhstan about the potential threat posed by this invasive tree-killer to native fir stands in the country. alien pest four-eyed fir bark beetle invasion Siberian fir damaged forest northeastern Kazakhstan first record tujerodni škodljivci lubadarji sibirska jelka zdravje gozdov severovzhodni Kazahstan prva najdba true false true Angleški jezik Slovenski jezik Znanstveno delo 2026-06-16 15:03:14 2026-06-16 15:03:14 2026-06-17 03:46:53 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Opis vira z dne 16. 6. 2026; str. 1003-1022 Vol. 9 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*4 2412-1908 10.5281/zenodo.10199570 281839619 https://zenodo.org/records/10199570 1 bd2674e1-6983-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45696 Kirichenko_et_al_final_(1).pdf Kirichenko_et_al_final_(1).pdf 1 15C6A4AB31C02D0E5BA7D8D13F18B69F d116762d72d51fc83f005078c3e5e4abbca6578eabf8a5d0a71064bcb7763256 dde8d8f9-6983-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45697 Gozdarski inštitut Slovenije 0 0 0
