        The objective of this study was to investigate the non-thermal sterilization effect of methods such as high hydrostatic pressure (HHP) and UV-irradiation (specifically with regard to the storage stability and shelf-life of carrot juice. The microbial counts of the non-sterilized product increased from 5.51 to 7.34 log CFU/mL up to the fifth day, and then decreased to 5.46 log CFU/mL at six days. UV-irradiation was increased from 2.37 to 4.92 log CFU/mL. HHP was maintained under the 3 log CFU/mL. The pH of UV-irradiation and HHP was maintained withing the range of 6.29~6.30 and 6.20~6.22 during storage. However, the pH arising from non-sterilization decreased from 6.31 to 4.49. The color of non-sterilization changed significantly during storage, but UV-irradiation and HHP were similar during storage. The β- carotene content of non-sterilization was noted to have decreased from 269.45 to 65.19 μg/mL during storage. The UV- irradiation and HHP decreased from 263.46 and 268.35~281.16 μg/mL to 243.42 and 244.09~269.29 μg/mL, respectively. In conclusion, these findings suggest that HHP can be used for the pasteurization, or sterilization, of carrot juice and the optimal condition is two minutes.

        This study was conducted to determine the effect of six different leguminous seeds a) cowpea, b) white kidney bean c) soybean (Cheongja) d) soybean (Daepung) e) mung bean and f) azuki bean on the nymphal development, mortality, adult longevity, fecundity and hatchability of Riptortus pedestris (F.) (Hemiptera: Alydidae). Total developmental time ranged from 18 to 25 days; R. pedestris fed on white kidney bean took the longest time. There was no difference in mortality among the bugs fed on the legumes except those fed on white kidney bean which had the highest mortality (94%). Also, adult bugs fed on white kidney bean showed the shortest longevity. Total number of eggs laid by adult female and the hatchability of the eggs were highest from the bugs fed on cowpea. Higher reproductive success of R. pedestris fed on cowpea suggests that cowpea could be very suitable legume for the bug and it can be used as a trap crop against the bean bug.

        Several pentatomids and an alydid are reported inflicting losses in several host plants ranging from leguminous crops to fruit orchards in Korea. Understanding their visual preference would help develop mass trapping or efficient monitoring device. Visual preference of the major pentatomids and an alydid bugs to different colors and light emitting diodes (LED) of different wavelengths were observed. Adults of pentatomid such as Halyomorpha halys Stål, Plautia Stali Scott, and Nezara sp., and an alydid Riptortus pedestris (F.) were exposed to seven different colors (black, yellow, green, blue, white, cream, orange) in a multiple choice tests. Also, adult and second instar nymphs of the bugs were released inside a hexagonal LED boxes consisting of LED lamps of six different wavelengths (375 to 630 nm). Most of the pentatomids showed highest preference to blue color followed by yellow and 530 nm LED. However, R. pedestris showed higher preference to the yellow color followed by blue and black. Second instar nymphs of all the tested species also showed higher preference to 530 nm. Their color and LED lamp preference would help in development of mass trapping device.

        Borami' is a new sweetpotato cultivar with light purple flesh developed at the Mokpo Experiment Station, The National Honam Agricultural Experiment Station, RDA. This cultivar was selected from the cross between 'Yamakawamurasaki' and 'Shinmi' in 1994, Se
