  • Integrated pest management system in Korean apple has significantly advanced for last few decades. However harmful effects of pesticides threats the ecosystem services of natural enemies and pollinators. Apple require cross-pollination and Insect pollination with diversity and abundance is one of the keys to profitable apple production in quantity and quality as well. Thus crop protection tools are to be administered in harmony to meet the pest suppression and protection of beneficial organisms such as natural enemies and pollinators. Adding onto the established IPM system, integrated pollinator-pest management (IPPM) concept is proposed as the future direction of apple IPM. For this, ecological enginnering of creating habitats for pollinators, landscape management and agroecosytem diversification as well as selective soft pesticide uses on time guided by pest monitoring and phenologyand targeted delivery are further proposed. Recent shift of agroecosystem from climate change and new pest outbreaks require new paradigm of pest management for sustainable agricultural production.

  • The purpose of this research is to analyze generation gap of positive effects on character strength for full life of adults in Korea and to verify mediating effect of volunteering from character strength in this roots. To test this effects, there was an investigated differences of perception on character strength, volunteering and full life from 1,405 Koreans. Then had set up the influence model of character strength on full life between generation, and verified the model through structural equation. Therethrough first, there was statistical significant between generations except the variables of trust, full life and meaning of life. Second, full life was positively influenced by character strength in early adulthood. Third, volunteering had fully mediated from character strength to full life in post middle aged adults, but had partially mediated in early adulthood. This will help acquaint us with importance of accompany with volunteering at character strength than character strength directly connects to full life. Based on these results, we are treated on importance of mediating volunteering effects and influences of character strengths on full life in Korean society.

Invention of the Portable Bark Remover for Control of Pine Wilt Disease by Disruption of Oviposition of Insect Vector (Monochamus alternatus) (소나무재선충병 매개충 솔수염하늘소(Monochamus alternatus) 방제를 위한 휴대용 수피제거기 개발 및 산란 방지 효과)

  • Pine wilt disease caused by pine wood nematode, Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle, has become the most serious threat to pine trees in Korea since 1988. Pine wood nematode is transferred to healthy trees by Monochamus alternatus (Coleoptera: Cerambycidae) during its maturation feeding and female oviposition. A typical control method against insect vectors in Korea is fumigation of the dead trees by using metam-sodium SL (25%). However, this method is not environment friendly because of the forest contamination by chemical application and destroying landscape by plastic cover. Portable Bark Remover (PBR) was invented to reduce these environmental problems. The vectors oviposit under the bark of the newly dead trees only. Debarking infested trees prevents the vectors from laying eggs and eventually, they can not complete their life cycle. The PBR is a modified debarking device that is attached on the top of the electrical chain saw, which allows ease and rapid debarking of the infested trees. The new method by PBR is expected to be more economic and effective than other conventional methods such as "crushing", "burning" and "fumigation".

  • The insect vector (Laodelphax striatellus) of rice black-streaked dwarf virus prefered rice plant to maize in feeding both in the cage and in the field, whereas the percent of infectious plants was much higher in maize than rice plants. The causal virus reduced the adult longevity, total number of hatching nymphs and maturity rate from nymphs of the insect vector. The percent of dry weight over fresh weight in rice from early to late growth stages was lower in diseased plants than in healthy plants but it was reversed on maize plant in early growth stage. In agarose gel-diffusion and microprecipitin serological tests, the intensities of antigen with antisera were in orders the preparation partially purified from infected maize leaves> rice stems> rice leaves> maize stems. The pholem galls in diseased plants developed well in the low temperature.
