Phylogenetic relationships between the European and Asian eight spined larch bark beetle populations (Coleoptera, Scolytidae) inferred from DNA sequences and fungal associates

The aim of this study was to establish the phylogenetic relationships of eight spined larch bark beetles. Beetles were collected from European and Asian populations, and from hosts and geographic areas where the species were first found. A region of the mitochondrial gene was analyzed and the blue-s...

Summary:The aim of this study was to establish the phylogenetic relationships of eight spined larch bark beetles. Beetles were collected from European and Asian populations, and from hosts and geographic areas where the species were first found. A region of the mitochondrial gene was analyzed and the blue-stain fungi associated with Ips cembrae in Europe were compared with those recorded as associated with the larch bark beetle in Japan. The European populations differed by 4.3 % from the Asian populations. The phylogenetic analysis placed the European and Asian haplotypes in significantly distinct clusters. This distinction was supported by the finding of an insertion/deletion in a non-coding region of the mitochondrial DNA. Furthermore, there are differences in the fungi associated with the eight spined larch bark beetles in Europe and Japan. The results suggest that the I. cembrae complex contains at least two taxa: I. cembrae infesting larch in Europe and I. subelongatus infesting larch in Asia.
