There has been a substantial controversy on the phylogenetic relationships among butterfly families and several competing phylogenetic hypothesis have been suggested. Among them the relationships of (((Nymphalidae + Lycaenidae) + Pieridae) + Papilionidae) has been further widely accepted. In this study, we sequenced EF1-α, COI, and 16S rRNA from 62 species belonging to four true butterfly families, Papilionoidea. Phylogenetic analyses using BI, ML, and MP showed that the traditionally recognizable families were strongly supported as monophyletic groups, with the exception of Nymphalidae, wherein the singly included species of Danainae was placed as basal lineage of the Nymphalidae + Lycaenidae group. Phylogenetic relationships among families supported the sister group relationship of Nymphalidae and Lycaenidae strongly by all analyses and placed Papilionidae as the most basal lineage of the Papilionoidea. On the other hand, the relationships of Nymphalidae and Lycaenidae group to Pieridae were either unresolved, revealing trichotomy, or the relationships of (((Nymphalidae + Lycaenidae) + Pieridae) + Papilionidae) as previously supported by several morphological and molecular works supported. Detailed within-family relationships among some genera also are shown in the presentation.

Phylogenetic relationships among 53 accessions of D.glomerata collected from 5 continents were investigated using simple sequence repeat (SSR) markers. 15 SSR primer pairs generated a total of 127 alleles, with an average of 8.5 alleles per locus. The average polymorphic rate (P) was 95.21 %. The genetic similarity (GS) among all accessions ranged from 0.43 to 0.94, with an average of 0.63. Analysis of molecular variance (AMOVA) indicated that larger proportions of variability existed within geographical regions (73.75%). High degree of genetic diversity was observed in Asia (P, 90.55%) and Europe (P, 86.61%) groups. Based on the cluster and principal component analysis, 53 accessions could be divided into five groups (GS=0.64) according to the nearest phylogenetic relationship.

These experiments were carried out to determine the optimal culture conditions for nine collected strains of Lyophyllum decastes(Fr.:Fr.)Sing. Bottle cultivation was used as a technique to characterize and develop new substrates as possible substitutes of sawdust. Nine kinds of Lyophyllum decastes were selected SPA 202 and SPA 205 fungus that mycelium grow fast and have high density. All cultures were incubated on Burke compost for 20 days. Growth of hyphae was optimal at temperatures between 20-25℃ and pH of 5.0-6.0. The best nutrient additives tested were lactose, yeast extract and MgSO4- 7H2O as carbon source, nitrogen source and mineral salt respectively. Collected strains of Lyophyllum decastes were incubated for 7 to 20 days after inoculation on agar medium followed by 45 to 75 days on sawdust substrate. The ideal optimal moisture percentage in sawdust media was 65%. The optimal species used was Quercus aliena , followed by Populus deltoides. Addition of 10% of Rice bran to Quercus aliena sawdust makes mycelial growth fast. Spawn running on the fermented sawdust media required 50 days at 20 to 25℃ and another 7 more days after covering the media with soil for promoting formation of fruitbodies. This was followed by cultivation for 10 to 11 days at 17 to 18℃ for initiation and 7 to 8 days for development of fruitbodies. The length of pilei and stipes which were harvested in optimal stage showed 60㎜ and 67㎜, respectively. Yields of strain SPA 202 grown on fermented sawdust medium could be up to 130g. The yields of strain Lyophyllum decastes used for fermented composition sawdust was the most appropriate recording 86% among them especially in SPA 202 artificial cultivation. Among 14 pleurotus eryngii , to identify the similarity ITS sequences and RAPD polymorphism are analyzed. ITS region sequences of 14 strains ,which have similar reqion sequences SPA 100, 101, 102 belong to Hypsizygus . 11strains belong to Lyophyllum decastes group. After classify 3 subgroup genus relationships among is analyzed. To analyzing diversity of artificial cultivated mushroom, after RAPD analysis excellent strains SPA 202 and SPA 203 show 75% similarity and pleurotus eryngii of Lyophyllum decastes SPA 103 and SPA 104 show 65%. As a result , SPA 202 which is cultivated in nature is estimated to Lyophyllum decastes by molecular biology method.

We have determined the complete mitochondrial genome of the yellow-spotted long horned beetle, Psacothea hilaris (Coleoptera: Cerambycidae), an endangered insect species in Korea. The 15,856-bp long P. hilaris mitogenome harbors gene content typical of the animal mitogenome and a gene arrangement identical to the most common type found in insect mitogenomes. As with all other sequenced coleopteran species, the 5-bp long TAGTA motif was also detected in the intergenic space sequence located between tRNASer (UCN) and ND1 of P. hilaris. The 1,190-bp long non-coding A+T-rich region harbors an unusual series of seven identical repeat sequences of 57-bp in length and several stretches of sequences with the potential to form stem-and-loop structures. Furthermore, it contains one tRNAArg-like sequence and one tRNALys-likes equence. Phylogenetic analysis among available coleopteran mitogenomes using the concatenated amino acid sequences of PCGs appear to support the sister group relationship of the suborder Polyphaga to all remaining suborders, including Adephaga, Myxophaga, and Archostemata. Among the two available infraorders in Polyphaga, a monophyletic Cucujiformia was confirmed, with the placement of Cleroidea as the basal lineage for Cucujiformia. On the other hand, the infraorder Elateriformia was not identified as monophyletic, thereby indicating that Scirtoidea and Buprestoidea are the basal lineages for Cucujiformia and the remaining Elateriformia.

Eumenis autonoe belonging to a lepidopteran family Nymphalidae (superfamily Papilionoidea) is an endangered species in Korea. Historically, the species was distributed in Europe and Asian region including a wide region in Korean peninsula. However, in Korean peninsula, the species is found only in two isolate dregions: South in a remote island Jeju, where altitude is higher than1, 400 meter on Halla Mt. and North in far northern Korean peninsula around Mt. Bekdu. In this study, we report the complete mitochondrial genome of the endangered E. autonoe collected from Mt. Halla. The 15,489-bp long E. autonoe genome has a typical gene content found in animal mitochondrial genomes and contains the gene arrangement identical to all other sequenced lepidopteran insects, which differs from the most common type found in insects, as the result of the movement of tRNAMet to a position 5’-upstream of tRNAIle. As seen in many other lepidopteran insects, no typical ATN codon for COI gene is available. Thus, we tentatively designated the CGA (arginine) found at the beginning of the COI gene, as has been suggested for lepidopteran COI starter. The intergenic spacer sequence located between tRNASer (UCN) and ND1 of E. autonoe mitogenome also contains the ATACTAA motif which is conserved in all sequenced lepidopteran species. The 678-bp long A+T-rich region, which is longest in sequenced lepidopteran insects contains ten identical tandem repeats composed of 27 bp plus one 13-bp long identical incomplete final repeat. Such repeat sequence is rare in the lepidopteran mitogenomes known so far. The E. autonoe A+T-rich region also contains a poly-T stretch located at the end of the region as 19 bp and also contains the downstream conserved motif ATAGA that were previously suggested to serve as a structural signal for minor-strand mtDNA replication. Phylogenetic analysis using the concatenated 13 amino acid sequences of PCGs among available six lepidopteran superfamilies (Tortricoidea, Pyraloidea, Papilionoidea, Bombycoidea, Geometroidea, and Noctuoidea) rooted with three dipteran species with BI and ML analyses supported the following topology: ((((Bombycoidea + Geometroidea +Noctuoidea) + Papilionoidea) + Pyraloidea) + Tortricoidea). Within Papilionoidea, a closer relationship between Lycaenidae and Pieridae, excluding Nymphalidae was observed. Further fruitful information will be available after more analysis is done.

Halacarid mites inhabit mainly in the bottom of the sea and their body lengths are approximately 0.5 mm. Few biological information about halacarids have been obtained. The phylogenetic study of halacarid mites has not been progressed and the phylogenetic relationship within the family Halacaridae is still unknown. Particularly there is no molecular study to infer phylogenetic relationship within the family. In the annual meeting of Acarological Society of Japan 2007, we developed the method for molecular analysis of 28S nuclear ribosomal gene in haracarid mites. Subsequently, we have further progressed the technique of the molecular analysis to infer the phylogenetic relationship of haracarids. The aim of the present study is to elucidate the phylogenetic position of the subfamily Rhombognathinae on the bases of molecular data. Halacarid specimens which were obtained from seaweeds and sandy segment at Japanese seacoasts, consist of eight genera in five subfamilies: Halacarinae (Halacarus sp., Agauopsis spp., Thalassarachna spp.), Halixodinae (Badyagaue sp., Agaue sp.), Copidgnathinae (Copidognathus spp.), Actacarinae (Actacarus spp.) and Rhombognathinae (Rhombognathus spp.). The template DNA was extracted and 28S nuclear ribosomal gene of the DNA was amplified by PCR reactions. And we determined approximately 400 base pair length of the gene. To construct phylogenetic trees by neighbor-joining method we calculated genetic distances of each operational taxonomic unit considering 1) transversions and 2) transitions and transversions based on Tamura - Nei model by using MEGA ver. 4 (Tamura et al. 2007). As a result, we got two trees both showing two main clusters. One of them includes only one subfamily Rhombognathinae and another consist of Halacarinae, Copidgnathnae, Actacarinae and Halixodinae. Rhombognathinae was greatly differentiated from the other subfamilies. Thus, Rhombognathinae possibly is a distinct taxon phylogenetically and this result supports the monophyletic nature obtained previously by morphological analysis.

In the preceding symposium, we presented the result of the phylogenetic analysis of Stigmaeopsis spider mites (Acari: Tetranychidae) in Japan using sequence data of the Cytochrome Oxidase subunit I (COI) region of mitochondria DNA. We analyzed haplotypes representing S. longus, S. celarius, S. takahashii and S. saharai, which inhabit bamboo species of the genera Sasa and Phyllostachys (Poaceae; Bambusoideae), and two forms of S. miscanthi (HG and LW) living on Miscanthus sinensis (Poaceae; Panicoideae). Both neighborjoining and maximum-likelihood methods revealed that Stigmaeopsis consists of seven monophyletic groups, in which two forms of S. miscanthi form two distinct monophyletic groups, whereas four species of bamboo-inhabiting species comprise a polyphyletic assembly. These results imply a mismatch between diagnostic morphological characters (i.e. the length of dorsal setae) and their phylogenetic lineages for bamboo-inhabiting species, requiring re-evaluation of the use of these characters. In addition, our results indicate that plural lineages coexist in a single habitat at various regions, suggesting that differentiated lineages secondarily encounter around southwestern Japan. Interestingly, the result of phylogenetic analysis on mitochondrial COI and nuclear ITS1 region was, in part, inconsistent in internal branches. In this symposium, I re-analyzed more these data by phylogenetic network analysis. Based on the results, I make some inference about the process of habitat expansion of these mites.

The 15,338-bp long complete mitochondrial genome (mitogenome) of the Japanese oak silkmoth, Antheraeayamamai (Lepidoptera: Saturniidae) was determined. This genome has a gene arrangement identical to those of all other sequenced lepidopteran insects, but differs from the most common type, as the result of the movement of tRNAMet to a position 5’-upstream of tRNAIle. No typical start codon of the A. yamamai COI gene is available. Instead, a tetranucleotide, TTAG, which is found at the beginning context of all sequenced lepidopteran insects was tentatively designated as the start codon for A. yamamai COI gene. Three of the 13 protein-coding genes (PCGs) harbor the incomplete termination codon, T or TA. All tRNAs formed stable stem-and-loop structures, with the exception of tRNASer(AGN), the DHU arm of which formed a simple loop as has been observed in many other metazoan mt tRNASer(AGN). The 334-bp long A+T-rich region is noteworthy in that it harbors tRNA-likestructures, as has also been seen in the A+T-rich regions of other insect mitogenomes. Phylogenetic analyses of the available species of Bombycoidea, Pyraloidea, and Tortricidea bolstered the current morphology-based hypothesis that Bombycoidea and Pyraloidea are monophyletic (Obtectomera). As has been previously suggested, Bombycidae (Bombyxmori and B.mandarina) and Saturniidae (A.yamamai and Caligula boisduvalii) formed a reciprocal monophyletic group.

In this study, we determined the complete mitochondrial genome of the jewel beetle, Chrysochroa fulgidissima (Coleoptera: Buprestidae), from four overlapping fragments. The 15,592-bp long C. fulgidissima mitogenome exhibits a gene arrangement and content identical to the most common type in insects. The start codon of the C. fulgidissima COI gene is unusual, in that no typical ATN codon is available. The 875-bp A+T-rich region is the shortest among the coleopteran mitogenomes that have thus far been sequenced in their entirety. The most unusual feature of the genome is the presence of three tRNA-like sequences within the A+T-rich region: two tRNALeu(UUR)-like sequences and one tRNAAsnlike sequence. These sequence stretches evidence the proper anticodon sequence and the potential to form secondary structures, but also harbor many mismatches in the stems. Phylogenetic analysis using a concatenation of 13 amino acid sequences of protein-coding genes among the available sequenced species of coleopteran superfamilies (Buprestoidea and Elateroidea belonging to the infraorder Elateriformnia, and Chrysomeloidea and Tenebrioroidea belonging to the infraorder Cucujoiformia) by Bayesian inference, maximum-parsimony analyses, and maximum-likelihood analysis unexpectedly revealed a lack of support for monophyletic Elateriformia.

A phylogeny of the tribe Aphidini (Hemiptera: Aphididae) was reconstructed using three molecular gene fragments: partial mitochondrial tRNA-leucine + cytochrome oxidase II (tRNA/COII), partial mitochondrial 12S + tRNA-valine + 16S (12S/16S), and nuclear elongation factor-1 alpha (EF1α) for a total of 41 species consisting of 37 representative species in Aphidini and 4 outgroup species in the tribe Macrosiphini. Also, to compare with the molecular analyses, a second phylogenetic reconstruction was performed using 41 morphological characters for equally weighted analysis. Minimum evolution, maximum parsimony, maximum likelihood, Bayesian phylogenetic analyses, and Bremer support test were performed for the phylogenetic construction. As our phylogenetic results were compared with the classical taxonomy based on morphological characteristics and biological data, we newly confirmed the following phylogenetic relationships within Aphidini: (1) each monophyletic subtribe of Aphidina and Rhopalosphina was supported by significant P values in the combined analysis, (2) contrary to the classical taxonomic position, Cryptosiphum should be moved to Macrosiphini because it is more closely related to Lipaphis and Brevicoryne in the myzine group of Macrosiphini, (3) The genus Toxoptera was possibly considered as a non-monophyletic group because three species were separately positioned in Aphidina, (4) In Rhopalosiphina, the genus Melanaphis was relatively divergent from three genera, Rhopalosiphum, Schizaphis and Hyalopterus, clustered in a strongly supported clade, (5) in the relationships among four the Aphis species-groups, which are accepted by most aphid taxonomists, most species except for some morphologically distinct species were separated to the two main lineages; the fabae-group was confirmed to be closely related with the spiraecola-group and craccivora-group, but the gossypii-group diverged as a monophyly from those three group.

We cloned seven genes encoding chitin synthases (CHSs) by PCR amplification from genomic DNAs of four strains of the genus Sporobolomyces and of Bensingtonia subrosea using degenerated primers based on conserved regions of the CHS genes. Though amino acid
