- ample of this is when non-native tree species are planted and some of their associated insect species also manage to establish in the new area. In Sweden, different species of larch (Larix spp.) are non-native tree species which has been planted over increasing areas during the last 50 years. The aim of the present study was to investigate if non-native bark- and wood-boring insects on larch have established in Sweden and, if so, their area of distribution. We used felled larch trees in 17 larch stands as a survey method for a broad spectrum of bark- and wood-boring species and pheromone-baited traps in seven ports and 47 larch stands for the bark beetle Ips cembrae during the years 2009-2014. Two non-native species were recorded: the cerambycid Tetropium gabrieli and the bark beetle I. cembrae. Tetropium gabrieli dominated in the felled larch trees and is distributed in the south-eastern part of Sweden. Within its range of distribution it seems to be present in most larch stands with suitable breeding material. Prior to our study this species was only recorded in dead larch trees close to a port. Ips cembrae was caught in traps in nine larch stands in the most southern part of Sweden demonstrating for the first time that the species have established in Sweden. The first individuals were caught in two nearby stands in 2011 and inspections of the stands revealed that the species had reproduced already in 2007 or 2008 in standing killed trees. The trapping demonstrated that the population level of I. cembrae increased more than four times from 2012 to 2014. Both T. gabrieli and I. cembrae are potential pest species and should be considered in the management of larch stands.
