As a result, 9 species of Scolytinae were recorded.

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).10aXylosandrus brevis1 aIto, Masaaki1 aKajimura, Hisashi  uhttps://weevil.myspecies.info/genetic-structure-japanese-populations-xylosandrus-brevis-curculionidae-scolytinae01037nas a2200169   4500008004100000020001400041245010400055210006900159260001300228300001200241490000600253520042600259100001700685700001800702700002200720856012500742       2007                        eng d  a0916-440500aAmbrosia beetles captured with ethanol traps in Takatori-yama Preservation Forest, Kochi Prefecture0 aAmbrosia beetles captured with ethanol traps in Takatoriyama Pre  cDecember  a245-2480 v63 aIn order to elucidate the beetle fauna in natural forests of Shimanto River Basin of Kochi Prefecture, southwestern Japan, we captured ambrosia beetles (Coleoptera: Scolytidae) with ethanol traps from March to October 2006 in Takatori-yama Plant Community Preservation Forest, which was one of old-growth natural mixed forest of conifers and broadleaved trees on low mountains.

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.10aXylosandrus crassiusculus1 aIto, Masaaki1 aKajimura, Hisashi  uhttps://weevil.myspecies.info/phylogeography-ambrosia-beetle-xylosandrus-crassiusculus-motschulsky-coleoptera-curculionidae-scolyt02066nas a2200313   4500008004500000020001400045245011600059210006900175260001100244300001200255490000700267520097600274653002701250653002801277653002401305653002601329653002601355653002601381653002501407653001701432653003101449653002501480653002501505653002501530100002201555700002201577700001801599856013501617       2008                        Engldsh    a0387-573300aTaxonomic changes and new records of Japanese bark and ambrosia beetles (Coleoptera, Curculionidae, Scolytinae)0 aTaxonomic changes and new records of Japanese bark and ambrosia   cNov 22  a231-2390 v363 aIn this study of some Japanese species of scolytine bark and ambrosia beetles, the following new synonymy is proposed: Arixyleborus malayensis (SCHEDL) (=Xyleborus yakushimanus MURAYAMA, syn. n.), Coccotrypes longior (EGGERS) (=Dryocoetes naidaijinensis MURAYAMA, syn. n.), Microperus perparvus (SAMPSON) (= Xyleborus tsukubanus MURAYAMA, syn. n.).

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' elytra. These findings contribute to the understanding of the relationships between S. birosimensis and its associated fungi.10aScolytogenes birosimensis1 aMasuya, Hayato1 aKajimura, Hisashi1 aTomisawa, Naohiro1 aYamaoka, Yuichi  uhttps://weevil.myspecies.info/fungi-associated-scolytogenes-birosimensis-coleoptera-curculionidae-infesting-pittosporum-tobira
