This studies was carried out to investigate the natural enemies of citrus red mite, pononychus citri and seasonal occurrence of its major beneficial insects in Yuzu groves (Chonnam province) from 1996 to 1998. Natural enemies against citrus red mite were 9 species including Oligota kashmirica benifica, 0. yasumatsui, Stethorus punctillum, Chrysopa pallens, Propylea japonica, Orius sauteri, Scolothrips takahashii, Amblyseius womersleyi and one unidentified species of thrips (Family: Phlaeothripidae). Among them, Oligota kashmirica benzficu and Stethorus punctillum were found to be dominant species. 0 . kushmirica henifica had 4-5 generations from middle May to middle November with peak in early September. S. punctillum had 3 generations from late May to late October with peak of late June to middle July. Population dynamics between predator ( 0 . kushmiricu benifica and S. punctillum) and prey (Panonychus citri) were quite well synchronized until September but predator density was decreased abruptly after October.

국립수목원은 열대유용식물의 BT산업 원천소재 확보 제공을 목적으로 열대자원연구센터를 건립하여, 열대 및 아열대 전시원을 관리하고 있다. 온실의 특성상 일반 재배환경과는 다르게 여러 종류의 식물의 혼합 식재되어 있는 특성이 있어서 농업환경과 달리 해충의 급격한 돌발에 의한 온실 전체적인 피해의 위험성이 적은 반면에 안정된 환경으로 인해서 해충의 취약한 몇몇 수목의 경우 해충이 급격히 늘어날 수 있다. 본 실험은 여러 종류의 식물이 혼재되어 있는 수목 온실 내에서 생물적 방제를 이용하여 주요 해충류인 진딧물류 및 가루 깍지벌레, 잎응애류 방제 가능성을 타진하고자 진행되었다. 진딧물이 집중적으로 발견된 열대식물 5종(Acalypha hispida, Justicia gendarussa, Hamelia patens, Ficus petersii, Hibiscus rosa-sinensis)을 중심으로 천적 방사 및 Banker plant 설치를 진행했다. 최초 조사일인 2015년 3월 10일, Tropical 1에 진딧물류의 발생이 많이 확인되어 포식성 천적인 미끌애꽃노린재를 투입했다. Tropical 2는 2015년 3월 17일 기생성 천적인 콜레마니진디벌과 선발된 Banker plant를 적용하여 방제 되었다. 철모깍지벌레가 발견된 열대식물 3종(Sanchezia parvibracteata, Brillantaisia lamium, Pseuderanthemum atropurpureum)을 중심으로 적용 천적으로 어리줄풀잠자리, 애홍점박이 무당벌레와 깍지무당벌레를 선별했다. 천적을 대상으로 철모깍지벌레에 대한 포식능력을 조사했으며 애홍점박이 무당벌레가 어리줄풀잠자리 보다 2.8배, 깍지무당벌레보다 2.9배 포식능력이 뛰어남을 확인했다. 잎응애류가 발견된 열대식물 2종(Acalypha wilkesiana, Erythrina caffra)은 천적으로 사막이리응애와 칠레이리응애를 적용하였다. 괭이밥응애 성충과 알의 포식력을 검증한 결과 사막이리응애가 괭이밥응애를 먹이로 증식이 가능한 것으로 확인되었다. 괭이밥, 괭이밥응애, 사막이리응애를 효과적으로 조합한 응애류 방제를 위한 새로운 Banker plant의 개발 가능성을 확인할 수 있었다. 연구는 열대온실의 열대식물 관리에 대한 생물학적 방제의 지속적인 모니터링을 통해 종합적 방제의 관리 자료로 이용되어 새로이 온실을 조성하는 경우 식재기반조성에 실질적인 도움을 줄 수 있으며, 추후 열대식물의 자원 식물로서의 활용성을 높일 수 있다.

Insect resources have been widely recognized that seven millions of insects exhibit it own biological activity by whole body or its metabolic intermediates. In order to investigate antioxidant activity and compare the cyclooxygenase-2 promoter activity from insect extract, we tested in vitro antioxidant assays and cyclooxygenase-2 promoter assay in Coccinella septempunctata Linne and Harmonia axyridis extracts have the anti-oxidant and cyclooxygenase-2 inhibition activities, we examined the anti-oxidant assays including DPPH, FRAP and linoleic acid, ana inhibition of cyclooxygenase-2 expression using a cyclooxygenase-2 promoter-inserted stable cell line. We found that Harmonia axyridis Pallas extract had potentials to anti-oxidant activity and inhibited about 25% of cyclooxygenase-2 transcription activity. These findings indicate that Coccinella septempunctata Linne and Harmonia axyridis Pallas extracts could be an useful insect resource for agrobiotechnological purposes.

Inflammation in the brain has known to be associated with the development of a various neurologiacal diseases. The hallmark of neuro-inflammation is the activation of microglia, brain macrophage. Pro-inflammatory compounds including nitric oxide(NO) are the main cause of neuro-degenerative disease such as Alzheimer's disease. In the study, we examined whether Harmonia axyridis extracts inhibit the NO production by a direct method using Griess reagent, western blotting and by RT-PCR(Reverse Transcription-Polymerase Chain Reactionin) the gene expression of inducible nitric oxide synthase(iNOS). Distilled water$(H_2O)$ and methanol(MeOH) extracts of H. axyridis inhibited the protein expression of TNF-a(Tumor Necrosis Factor) and IL-6(Interleukin) in LPS (Lipopolysaccharide) stimulated BV-2 cells at the concentration of 100 ng/ml. Incubation of BV-2 cells with the extracts of $H_2O$ of MeOH inhibited the LPS induced NO and iNOS protein. And this inhibition of iNOS protein is concordant with the inhibition of iNOS mRNA expression. These data suggested that H. axyridis extracts may play a crucial role in inhibiting the NO production.
