DISTRIBUTION OF THE SMALL SPRUCE BARK BEETLE <i>IPS AMITINUS</i> (EICHHOFF, 1872) IN WESTERN SIBERIA
Rossijskij žurnal Biologičeskih Invazij, 2021The data on 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 presented. Alien bark beetle species was recorded in the Siberian pine forests of the Tomsk, Kemerovo and Novosibirsk regions. According to the modern data the

Abstract In 1913, Fuchs described Ips amitinus var. montana as a race of Ips amitinus. The differences were based on the different host trees and on body size. The main hosts of I. amitinus is Picea abies and of I. amitinus var. montana are Pinus cembra and Pinus montana. Four populations of I. amitinus and two populations of I. amitinus var. montana

Abstract Invasive populations of small spruce bark beetle Ips amitinus were first registered in 2019 in the southeast of Western Siberia. In natural stands of Siberian pine (Pinus sibirica Du Tour), several hundred hectares of outbreak foci of the alien bark beetle were identified.

Zur Kenntnis des „Kleinen Buchdruckers”, Ips amitinus (Eichh.) (Col., Scolytidae)
Anzeiger Für Schädlingskunde, Pflanzenschutz, Umweltschutz, 1977On the knowledge of Ips amitinus (Eichh.) The authors compile some quantitative data on the “Smaller Spruce Bark Beetle”Ips amitinus, comparing it withIps typographus. In addition to well known values, differences were measured in diameter of entrance holes, distance between the egg niches, and size of the larvae's head capsules.

AbstractPheromone producing males of the two subspecies, Ips amitinus and Ips amitinus var. montana, respectively, are fully cross‐attractive to field populations of both subspecies and produce identical patterns of male‐specific terpene alcohols upon feeding in the phloem tissue of their respective host trees, Picea abies and Pinus cembra: major ...

The ascomycete fungus Metschnikowia typographi sp.nov. is described. It infects the spruce bark beetles Ips typographus L. and Ips amitinus Eichl. Masses of vegetative cells and navicular asci (I. typographus 13-17 x 2 microns; I. amitinus 17-22 x 2 microns) were found in cells of the midgut epithelium and in the body cavity of infected beetles.

The small spruce bark beetle Ips amitinus is a widespread species in many European countries that has been actively spreading into Northern Europe in the recent decades. In Russia, I. amitinus is present in the western, northwestern, and northern regions of the European part, with a tendency for range expansion. The species was first recognized in West
