In order to accumulate the ecological information of Drosophila suzukii for export negotiations of domestic strawberry, we weekly monitored occurrence of D. suzukii at three strawberry fields located in Gok-seong, Dam-yang and Hwa-sun using the best combination of trap and attractant from November 2017 to May 2018, the period of strawberry production. Monitoring was carried out at three sites (a hill located 150 meter distant to greenhouse, outside greenhouse and inside greenhouse) in Gok-seong. Drosophil suzukii was trapped at three short periods from November to the beginning of December, from the end of December to the beginning of January, and from April in a hill. At outside greenhouse, D. suzukii was trapped at two short periods from November to the early December and the beginning of May. In inside greenhouse, it occurred once after May 24th. Gok-seong data can be summarized as more occurrence for longer period as the distance to greenhouse increases. Dam-yang occurred once in a short period inside greenhouse and hill, respectively on May. In case of Hwa-sun, D. suzukii did not trapped in whole trapping sites during trapping period, except for the surrounding grape and peach cultivation areas at the end of November. Summarized, no occurrence periods are from November 20th, 2017 to May 14th, 2018 inside greenhouse; from December 11th, 2017 to May 3rd, 2018 outside greenhouse; and from January 8th, 2018 to April 12th, 2018 on a hill. In connection with strawberry culture, the D. suzukii tends to occur at the beginning and the end of the strawberry production period. We expect this result can serve as a helpful data for export negotiation for quarantine.

The nerippe fritillary butterfly, Argynnis nerippe , is listed as an endangered species in Korea. Establishment of effective conservation strategies can be aided by the development and application of molecular markers that can be used to investigate the population genetics of the butterfly. Therefore, in this study, we identified ten microsatellite markers specific to A. nerippe using the Next-Seq 500 platform, and applied these markers to investigate the characteristics of five South Korean butterfly populations. Genotyping of 48 A. nerippe individuals from five localities showed that at each locus the number of alleles ranged from 4 to 14, and that the observed and expected heterozygosities were 0.324–0.863 and 0.138–0.985, respectively. Significant deviation from the Hardy–Weinberg equilibrium was not observed at any locus. Population structure analysis indicated that there are two genetic groups in Korea, but no population-based gene pool assignments were found. Analysis of FST, RST, and a principal coordinates analysis suggested that the Gureopdo and Yaecheon populations were isolated from other populations. Genetic isolation of the Gureopdo population may be a consequence of unequal population change between Gureopdo and inland populations and to the offshore habitat of Gureopdo. Genetic isolation of the Yaecheon population may be a consequence either of the southernmost location of the population or of the limited sample size available. Further studies with increased sample sizes will be necessary to draw robust conclusions on population isolation and to devise conservation strategies.

Bumblebee, Bombus ardens ardens (Apidae: Hymenopera), is an important resource for pollination that is most widely distributed in Korea. This study utilized microsatellite markers for investigation of genetic diversity and geographic relevance of the B. a. ardens populations in Korea. Through Next Generation Sequencing analysis, we identified 10 microsatellite markers and genotyped for 107 individuals of B. ardens collected from 10 populations. At each locus the number of alleles ranged from 10 to 23; the observed and expected heterozygosities ranged from 0.8909 to 1.0000 and 0.6641 to 0.8422, respectively; and inbreeding coefficient(FIS) ranged from –0.5053 to –0.0891. Significant deviation from the Hardy–Weinberg equilibrium was not observed at any locus. Population structure analysis indicated that there are three genetic groups in Korea with each Jeongseon and Ulleung-do composed of different gene pool from the remaining other populations. Similarly, Principal coordinates analysis also showed the same pattern. FST and RST analyses showed that each Jeongseon and Ulleung-do population had a significant genetic distance from other populations. Considering these results, genetic isolation of Ulleung-do may be explained by “Oceanic island” status and Jeongseon, which showed the positive FIS (0.069) and genetic isolation may be caused by its location on the east side of Baekdudaegan and by on-going inbreeding with a small population size.

The yellow-legged hornet, Vespa velutina nigrithorax (Hymenoptera: Vespidae), invaded into South Korea in 2003. Currently, V. velutina is distributed throughout South Korean regions,. A genetic trait of invasive species provides important data for environmental risk assessment. In this study, we analysed the genetic variation of the V. velutina among the populations of South Korea and other foreign countries using partial sequences of mitochondrial COI, CytB and 16S rRNA. We further developed intergenic spacers (IGS2 and IGS3) to detect genetic variation among Korean populations. Each single haplotype was recovered from the domestic V. velutina from each coding gene sequence. Korean individuals shared the haplotype with that of Japan and China. Phylogenetic analysis (excluding 16S rRNA) using available sequences and ours showed the presence of two groups: the Indonesia and Malaysia group and another group (Korea, Japan, China, France, Vietnam and Thailand). The newly developed IGS2 and IGS3 markers resulted in each seven and four haplotypes, providing better resolution than coding gene sequences. Analysis of Molecular Variance using the combined sequences of IGS2 and IGS3 showed that the majority of variance was allocated to each population and only minority of variance is allocated to among-populations. This result may indicate that the V. v. nigrithorax invaded in Korea shows a single panmictic population and this possibly suggest that Korean population may have originated from small founder individuals.

동남아시아에 발생하던 등검은말벌은 최근 국내 뿐만 아니라 프랑스와 일본, 유럽 전역으로 확산되어 전 세계 양봉 산업에 극심한 피해를 주고 있다. 등검은말벌을 방제하기 위해 다양한 방제 방법들이 연구되고 있으며, 그 중 말벌 유인제에 대해 국제적으로 많은 연구가 진행되어 왔으나 이 역시 지속적인 개발이 필요한 실정이다. 따라서 본 연구에서는 시판 유인제와 최근 (주)다목에코텍에서 새롭게 개발한 신규 개발 유인제에 대한 효능 검정을 수행하였 고 양봉장에 출현하는 국내 발생 말벌속의 발생양상을 조사하였다. 담양 1개소와 곡성 2개소에 기존 유인제과 신규 유인제를 장착한 포획기를 각 3쌍씩 설치하여 2016년 9월부터 11월말까지 주 1~2회 관찰하였다. 그 결과 국내 발생 말벌속 중 등검은말벌(7,787 개체)이 가장 많이 포획되었고, 다음으로 장수말벌, 말벌, 좀말벌, 꼬마장수말벌, 털보말벌 순으로 포획되었다. 두 유인제의 포획력 검정 결과, 신규 개발 유인제가 통계적으로 유의하게(P < 0.01) 등검은말벌 포획력이 높음을 보였다.

The Acoptolabrus changeonleei Ishikawa et Kim, 1983 (Coleoptera: Carabidae), has been listed as an endangered insect in South Korea. The complete mitochondrial genome of the species was 16,831 bp with a typical set of genes (13 protein-coding genes [PCGs], 2 rRNA genes, and 22 tRNA genes) and one non-coding region, with the arrangement identical to that observed in most insect genomes. Phylogenetic analyses with concatenated sequences of the 13 PCGs and 2 rRNA genes, using the Bayesian inference (BI) and maximum-likelihood (ML) methods, placed A. changeonleei as a sister to the within-subfamilial species Damaster mirabilissimus in Carabinae, with the highest nodal support by both analyses.

Previously, a partial mitochondrial COI and CytB gene sequences have been used to infer genetic diversity and gene flow of the species. In this study, we additionally collected C. tripartitus from one previous and two new localities, sequenced the COI and CytB genes. Sequence divergence of current samples showed slightly lower values, but nearly equivalent to previous study. Haplotype diversity was still high and nucleotide diversity indicating that Seogwi-dong showed the highest estimates in both gene sequences. Gene flow among populations is high, but a significance difference was detected between Gulupdo and Anmado; and between Gulupdo and Seogwi-dong only in COI sequences (P < 0.05). Considering the high genetic diversity and gene flow in C. tripartitus populations, one of the major issues regarding conservation seems not to be the recovery of genetic diversity as has been suggested before.

The red-spotted apollo butterfly, Parnassius bremeri Bremer, 1864 (Lepidoptera: Papilionidae), has been listed as an endangered species in Korea. We developed microsatellite markers by nest-generation sequencing (NGS), selected 12 markers, and applied the markers to available South Korean populations to understand population genetic characteristics. The genotyping of 40 P. bremeri individuals from three localities in South Korea showed that at each locus, the observed number of alleles ranged from 17 to 43, the observed and expected heterozygosities were 0.84722-0.90556 and 0.76045-0.79208, respectively, and FIS was –0.155 to –0.121. STRUCTURE analysis supported the presence of two genetic pools in all three populations, although an immediate reason for this subdivision is not known. The population based FST, RST, and front wing length collectively suggest that at least Samchuk population in Gangwon Province has a significant distance. Further scrutinized analysis is undergoing.

Despite of a substantial effort, the phylogeny of Lepidoptera still has unstable taxa and unresolved relationships particularly form Apoditrysia to Ditrysia (e.g. phylogenetic position and familial relationships of Gelechioidea, the monophylies of Tineoidea and Zygaenoidea and so on). We performed phylogenetic analysis using ~13,000-bp length of mitogenome sequences form 50 species (with seven species in two superfamilies form this study) representing 13 superfamilies to improve the lepidopteran phylogeny from Apoditrysia to Ditrysia. A close relationship of Gelechioidea to Obtectomera than to apoditrysian taxa was noteworthy, although the nodal support is very weak (ML, 23%; BI, BPP = 0.94). Monophyly of Zygaenoidea without Epipyropidae (Epipomponia nawai) was also noteworthy in spite of weak nodal support (ML, 64%; BI, 1.0). Scrutinized analysis is currently underway.

We sequenced the complete mitochondrial genome (mitogenome) of Vespa velutina nigrithorax and V. ducalis (Hymenoptera: Vespidae). The genomes were 16,475-bp and 15,779-bp long and contained typical sets of genes. The V. velutina and V. ducalis A+T-rich region was 132-bp long and 166-bp long and was the shortest of all sequenced Vespoidea genomes. Start and stop codons in several Vespa species—including V. velutina and V. ducalis—were diversified, despite these species belonging to the same genus. In comparison with the ancestral mitogenomes, Vespa mitogenomes showed substantial gene rearrangement; however, we detected no gene rearrangement among Vespa species. We conducted phylogenetic reconstruction based on concatenated sequences of 13 PCGs and two rRNAs in available species of Vespoidea—22 species in six subfamilies in two families (Vespidae and Formicidae). The Bayesian inference and maximum likelihood (ML) methods revealed that each family formed strong monophyletic groups.

The number of reported mitochondrial genomes (mitogenomes) from the monotypic Lasiocampoidea has been limited until recently. In this study, we sequenced the complete mitogenome of the lappet moth, Kunugia undans (Lepidoptera: Lasiocampidae), and compared it to those of other lasiocampid species and macroheteroceran superfamilies (59 species in six superfamilies). The 15,570-bp long K. undans genome had the typical set of genes found in animal mitogenomes, with the exception of one additional trnR that are located between trnA and trnN loci. Considering that the two trnR copies are located in tandem with proper secondary structures and identical anticodons, a gene duplication event might be responsible for the presence of the two tRNAs. In summary, the general mitogenome characteristics of Lasiocampoidea did not differ greatly from the remaining macroheteroceran superfamilies, but it did exhibit some unique features.

Currently, only limited number of mitochondrial genomes (mitogenome) is available from Odonata. In order to extend current mitogenome data for comparative biology and phylogeny we sequenced complete mitogenomes of two endangered dragonfly species, Libellula angelina and Nannophya pygmaea (Ododana: Libellulidae). The whole genomes were 15,233 bp in L. angelina and 15,112 bp in N. pygmaea and included a typical set of genes (13 protein-coding genes, two rRNA genes, and 22 tRNA genes) and one major non-coding A+T-rich region. The arrangement of the genomes was identical to typical one found in insects. Phylogenetic reconstruction using concatenated sequences of 13 PCGs and two rRNAs of Odonata (17 species in eight families in three suborders) using both Bayesian Inference (BI) and Maximum Likelihood (ML) methods have shown a strong support for monophyletic Zygoptera (BI, BPP = 1 and ML, 100%). Currently, further scrutinized analysis is under progress.
