To profile the proteome in porcine plasma, blood samples were collected from adult male barrows and those plasma were retrieved. For the depletion or pre-fractionation of high-abundance proteins, plasma samples were treated with commercial kits. Then, protein profiling was initiated using one and two-dimensional electrophoresis. Proteins were spotted and then identified by MALDI-TOF-TOF and LC-MS-MS. In the results, more than forty six proteins were identified and the reference map was constructed. The pre-treatment for the removal of high-abundance proteins caused the changes in 2-DE images and some of the proteins were newly uncovered after the most of high abundant proteins were removed. However, it is expected for further steps necessary to identify more low-abundance proteins that may contain potential bio-markers.

Here, we present an approach of blood plasma proteome profiling and their comparisons between the young and the adult pigs as prerequisite for the identification of bio-markers related to the health conditions, growth performance and meat quality. To profile the proteome in porcine plasma, blood samples were collected from 19 young piglets and 20 adult male barrows and the plasma was retrieved. Then, protein profiling was initiated using one and two-di-mensional electrophoresis. Proteins were spotted and then identified by MALDI-TOF-TOF and LC-MS-MS. In the re-sults, more than thirty-six and twenty eight protein spots were selected in young piglets and adult pigs, respectively and twenty three proteins were identified. The proteome profile images were compared between those ones using Image Master Version 7.0. The image of expressed proteome showed that most of proteins from plasma of young pig-let separated clearly and concentrated in 2DE display compared to ones from adult. Image analysis in detail was car-ried out to look for the specific proteins related to age progression. It demonstrated that the characteristics of proteome expression could be distinct to their age stages. Further investigations needed to proceed to understand the age de-pendent change of protein conformation and biological meaning of those differences in proteome expression between young and mature adult pigs.

The green pale plant bug, Apolygus spinolae was one of the main insect pests that damaged leaves and fruit in grapes and its damage status was firstly reported in 2000 in grape orchards. This research was conducted to evaluate the distribution and difference in damage rate depending in management type of grapevine orchards (domestic sale farm vs export farm) in the export complex area of Korea (Hwangsung in Gyeonggii, Sangju and Yeongcheon in Gyeongbuk, Namwon in Junbuk and Yeongdong in Chungbuk) from 2010 to 2012. Damage by A. spinolae occurred in all 62 survey farms and damage rate differed depending on locality and individual farms in the same area. Damage rate was lower in export farms than in domestic sale farms, and damage rate of leaves was highly correlated with damage rate of new shoots. 15 species of hemipteran insect were attracted to sticky traps and A. spinolae was the dominant species. The attracted number of A. spinolae in the sticky traps differed depending on locality, and more occurred in domestic sale farms than expert farms. A. spinolae was continually attracted to sticky traps in the harvest period in grapevine orchards.

This report is a part of research on pests occurring in grapevine orchards in export complexes (Hwangsung in Gyeonggi, Sangju and Yeongcheon in Gyeongbuk, Namwon in Junbuk and Yeongdong in Chungbuk) from 2010 to 2012. This research was conducted to evaluate the distribution and difference in damage rates depending on management types of grapevine orchards (domestic sale farm vs. export farm). Damage by Arbordia spp. occurred only in 2010 and differed depending on localities and individual farms in the same area. Numbers of orchards damaged by Arbordia spp. were one, two and four in Hwasung, Namwon and Sangju, respectively, and the damage rate was below 6.2%. There was no damage in the orchards in 2011 and 2012, however, Arbordia spp. were collected on sticky traps in the orchards. A. nigrigena and A. kakogawana were the dominant species in Yeongcheon and Yeongdong, respectively, in 2011. A. kakogawana, A. maculifrons and A. nigrigena were collected on sticky traps in 2012. Collected numbers of Arbordia spp. were different depending on localities and management types of the orchards (domestic sale vs. export). A. kakogawana was the dominant species in all the survey sites and the densities were higher in the domestic sale farms than in the export farms.
