        Background: Somatic cell nuclear transfer (SCNT) is a prominent technology that can preserve superior genetic traits of animals and expand the population in a short time. Hematological characters and endocrine profiles are important elements that demonstrate the stability of the physiological state of cloned animals. To date, several studies regarding cloned camels with superior genes have been conducted. However, detailed hemato-physiological assessments to prove that cloned camels are physiologically normal are limited. In this study, We evaluated the hemato-physiological characteristics of cloned male and female dromedary camels (Camelus dromedaries). Methods: Therefore, we analyzed variations in hematological characteristics and endocrine profiles between cloned and non-cloned age-matched male and female dromedary camels (Camelus dromedaries ). Two groups each of male and female cloned and non-cloned camels were monitored to investigate the differences in hemato-physiological characteristics. Results: All the animals were evaluated by performing complete blood count (CBC), serum chemistry, and endocrinological tests. We found no significant difference between the cloned and non-cloned camels. Furthermore, the blood chemistry and endocrine profiles in male and female camels before maturity were similar. Conclusions: These results suggest that cloned and non-cloned camels have similar hematological characteristics and endocrine parameters.

        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.

        Euzophera batangensis (Lepidotera: Pyralidae) is seriously damaging trunks or branches of persimmon tree (Diospyros sp.). We tested the attractiveness of (Z)-9-tetradecen-1-ol (Z9-14OH) and (Z9,E12)-tetradeca- 9,12-dien-1-ol (Z9,E12-14OH) with single or blended baits at southern parts of Korea in 2014 and 2015. The monoene was not attractive at all at three places during the two years. In 2014, diene was equally or more attractive than the mixture in Jinju and Suncheon, respectively. In 2015 too, the attractiveness of diene and mixture was not different in Jinju and Munsan. Monitoring of the seasonal occurrence of E. batangesis with the sex pheromone components revealed that it occurred three times a year; the first occurrence from early April to mid May, the second from early Jun to mid July, and the third from late August to late September.

        In order to understand evolutionary characteristics of gene rearrangement in Lepidoptera, we collected all available complete mitogenome (mitogenome) sequences registered in GenBank (274 mitogenomes from 44 families in 23 superfamilies as of August 6, 2015). It turned up six rearrangements that differ from the arrangement of ancestral insects, including that of the gelechioid Mesophleps albilinella that we sequenced in this study. The M. albilinella mitogenome has a unique gene arrangement among the Gelechioidea: ARNESF (the underline signifies an inverted gene) at the ND3 and ND5 junction, as opposed to the ARNSEF that is found in ancestral insects. Most of the rearrangements can be explained by the tandem duplication-random loss model, but inversion, which requires recombination, is also found in two cases, including M. albilinella. Excluding the MIQ rearrangement at the A+T-rich region and ND2 junction, which is found in nearly all Ditrysia, most of the remaining rearrangements found in Lepidoptera appear to be independently derived in that they are automorphic at several taxonomic scales. Current mitogenomic data are limited, particularly for congeneric data. Thus, future research focused on congenerics could clarify evolutionary independency at the generic level also.

        Insect antennae play important roles in finding mates and in locating food source and oviposition sites. Riptortus pedestris is an important pest of soybean and sweet persimmon in Korea. The male R. pedestris adult produce the aggregation pheromone attracting the conspecific nymphs and both sexes of adults. The pheromone was known as a cue for food finding, but the 1st instar nymph can develop to the 2nd instar without food. This phenomenon may suggest that the 1st instar nymph may have different sensilla system from other instars. Thus, we investigated the morphology and distribution of antennal sensilla and antennal response to the aggregation pheromone (AG) of each nymphal stage using Scanning Electron Microscope (SEM) and Electroantennography (EAG). As expected, first instar nymph did not have sensilla trichodea 3 (T3) and chaetica 3 (Ch3) which existed in other instar nymphs. The antennae of the 1st instar nymph did not responded to AG, with no difference from control. For further elucidation of the functions of sensilla T3 and CH3, single sensillum recording to AG will be done.

        The change of quality characteristics with storage temperature (room (25°C), low (15°C) and cold (4°C) temperature) and period of unhulled foxtail millet (Setaria italica Beauv. cv. Samdame and Gyeongkwan 1), proso millet (Panicum miliaceum L. cv. Hwanggeum-gijang and Manhongchal) and sorghum (Sorghum bicolor (L.) Moench cv. Hwanggeumchal and Donganme) were evaluated. The 1,000 grain weight, lightness, redness, yellowness and moisture content with storage temperature and period of unhulled foxtail millet, proso millet and sorghum were not showed difference. Germination percent and milling recovery of foxtail millet, proso millet and sorghum decreased with increasing storage temperature and period. Fat acidity of stored foxtail millet, proso millet and sorghum was increased with increasing storage period, and the higher temperature increased more. The results of this study show that the storage of foxtail millet, proso millet and sorghum at the low and cold temperature is better than the room temperature. Especially, in mind of the economics, the storage method is good low temperature than cold temperature.

        This study was carried out to compare the physicochemical characteristics of vinegars fermented from cereal crops such as glutinous and nonglutinous foxtail millet, proso millet, sorghum and adlay, and Incalgyun. The crude protein, minerals and P2O5 contents of vinegars fermented from cereal crops and Incalgyun were higher than circulation brown rice vinegar. Brix degree, turbidity and pH of vinegar fermented from cereal crops and Incalgyun were higher, and total acidity was lower than circulation brown rice vinegar. The glucose content of circulation brown rice vinegar was 4.89 mg/mL, and vinegars fermented from cereal crops were 0.00-5.62 mg/mL. The total organic acid content of circulation brown rice vinegar was 41.92 mg/mL, and vinegars fermented from cereal crops were 12.14-42.31 mg/mL. The major organic acids were acetic acid, succinic acid and citric acid. The total polyphenol content of circulation brown rice vinegar was 0.023 mg/mL, vinegars fermented from cereal crops were 0.286-0.413 mg/mL, and vinegars fermented from cereal crops and Incalgyun were 0.266-0.396 mg/mL. The ABTS and DPPH radical scavenging activities of vinegars fermented from cereal crops were higher than circulation brown rice vinegar.
