Distribution of the small spruce bark beetle Ips amitinus (Eichhoff, 1872) in Western Siberia.
Data on the distribution of small spruce bark beetle Ips amitinus (Eichh.) (Coleoptera: Curculionidae: Scolytinae), a new invasive pest of European origin on the territory of Western Siberia, are given. The alien bark beetle species was found in the Siberian pine forests of Tomsk, Kemerovo, and Novosibirsk oblasts. According to the modern data, the total range of invasion is more than 30 000 km2 with a tendency for further expansion. I. amitinus forms outbreak foci, causing great harm to nature reserves and valuable commercial and breeding Siberian pine Pinus sibirica Du Tour stands near settlements.
