	abstract = {We examined the genetic structure of populations of an ambrosia beetle, Xylosandrus brevis (Eichhoff) (Curculionidae: Scolytinae), to understand its colonization dynamics. We collected specimens from 20 sites in Japan and studied the genetic structure of these populations using portions of the mitochondrial cytochrome oxidase I gene (COI). A phylogenetic analysis showed three distinct lineages (clades A, B, and Q within X. brevis. Clade A had 65 haplotypes from all the populations, except for populations from Nagano (Chiisagata-gun) and the Ryukyu Islands (Ishigaki), whereas clade B had 14 haplotypes from nine populations (Yamagata, Saitama, Shimo-Minochi-gun, Chiisagatagun, Toyota, Watarai-gun, Wakayama, Tottori, and Kochi), and clade C had 6 haplotypes from the Ryukyu Islands (Ishigaki) population (and nowhere else). Nested clade phylogeographic analysis showed 65 clade A haplotypes and 14 clade B haplotypes geographic-ally structured ill two clades, respectively. A contact zone was identified in the Chubu and Tokai areas. Our results suggest that gene flow and individual movement of X. brevis between the Ryukyu Islands and the other three main islands of Japan has been rare, and X. brevis may be divided into two populations, eastern-central and northern-western, with little gene flow between the four areas of western Japan (Kinki, Chugoku, Shikoku, and Kyushu).},

	abstract = {We examined the genetic structure of populations of an ambrosia beetle, Xylosandrus crassiusculus. Specimens were collected from 22 sites in Japan and their genetic structure was studied using a portion of the mitochondrial cytochrome oxidase I gene. Phylogenetic analysis revealed three distinct lineages (clades A, B and C), each of which was divided into two subclades (A1, A2, B1, B2, C1 and C2). Subclade A1 had 17 haplotypes from Hokkaido, Honshu and Kyushu populations, subclade A2 5 haplotypes mainly from Shikoku populations, subclade B1 15 haplotypes from central and western Honshu and Amami populations, subclade B2 2 haplotypes only from Naha population, subclade C1 4 haplotypes from Amami and Naha populations, and subclade C2 5 haplotypes only from Ishigaki population. Analysis of molecular variance detected genetic differentiation among populations. The data imply that the genetic structure of Japanese populations of X crassiusculus has been affected by the geological history of the Japanese islands. but that the mtDNA phylogeographic pattern is so complex that we could not infer any simple scenario of population history in X crassiusculus.},

We isolated fungi from adult S. birosimensis in nine different localities in Japan to assess their potential association and predict their contribution to the success of the beetle. Results from morphological identification of associated fungi showed that the beetle was associated with Fusarium solani and Candida spp. Furthermore, molecular analysis showed that F. solani was most closely related to the plant pathogenic fungus F. solani f. sp. mori. Fungal isolation from surface-sterilized, dissected beetles and scanning electron miscroscope (SEM) observation of the body surface suggested that the associated fungi were carried in the pits on the beetles{\textquoteright} elytra. These findings contribute to the understanding of the relationships between S. birosimensis and its associated fungi.},
