Seventeen species (Artemisia argyi, Areca catechu, Auckulandia lappa, Atractylodes lancea, Cassia obtusifolia, Cyperus rotundus, Carthamus tinctorius, Dryopteris crassirhizoma, Eugenia caryophyllata, Lonicera japonica, Prunus mume, Piper nigrum, Quisqualis indica, Sophora flavescens, Taraxacum mongolicum, Torreya nucifera, and Zanthoxylum piperitum) in 12 families herbal hot and cold water extracts were evaluates to control pine wood nematode, Bursaphelenchus xylophilus in laboratory. Among them, hot and cold water extract of A. lancea with concentration of 10 fold showed 100% mean mortality rate against B. xylophilus at 1 day of exposure time in petri dish. With 10 fold concentration of cold water extracts of P. nigrum, Q. indica, S. flavescens and T. mongolicum and hot water extract of C. tinctorius showed 100% mean mortality rate against B. xylophilus at 1 day of exposure time too. Cold water herbal extracts with 1,000 fold concentration killed nematodes, but low efficacy to B. xylophilus. Hot water extract of P. nigrum with 500 fold concentration was the highest efficacy to B. xylophilus.

Purpose: The resonant frequency to improve the quality of the traffic card terminal through Six Sigma problem solving methodology. Methods: The improve the quality of the resonant frequencies to find the optimal conditions of a two-lev-el experiments to discover the cause relating to the absorber that affects the resonance frequency of the traffic card terminal. Results: Was adopted as the thickness of the absorber is the magnetic permeability and loss factor as a factor affecting the resonance frequency of the traffic card terminal thickness 0.3 [mm], the mag-netic permeability 30 [μ], to determine the optimal conditions of 1.4% as loss rate capability resonant frequency the improvement in the 3.04σlevel 4.19σ level. Conclusion: It was appropriate to utilize Six Sigma methodology of judging quality improvement roadmap to improve the resonance frequency, and quality of traffic card terminal activity results through a step-by-step DMAIC Six Sigma problem solving methodology.

이동운(Dong Woon Lee) 한국잡초학회 2021 Weed & Turfgrass Science Vol.10 No.3
검거세미나방과 포충나방은 골프장 잔디를 가해하는 주요 나방류 해충이다. 본 연구는 골프장에서 검거세미나방과 포충나방의 발생 경과를 알아보기 위하여 성페로몬트랩을 이용하여 조사하였다. 검거세미나방과 포충나방의 유인수는 년도 별로 차이가 있었으며 지역 간에도 차이가 있었다. 전체적으로 검거세미나방은 5월 하순에서 6월 초순과 6월 하순에서 7월 중순, 8월 중순에서 9월 중순 사이에 발생 피크를 보였으며 포충나방은 6월 하순에서 7월 초순, 7월 중순, 9월 하순에서 10월 중순에 발생 피크를 보였다. 검거세미나방은 델타트랩보다 콘트랩에서 유인수가 많았다. 검거세미나방은 2화기의 발생량이 많았으며 포충나방은 3화기의 발생량이 많았다. 골프장에서 두 해충의 효율적 방제를 위해서는 정확한 예찰을 통한 관리방법 강구가 필요할 것으로 생각된다. The black cutworm (Agrotis ipsilon) and sod webworm are the main lepidopteran pests that injure the turfgrasses of golf courses. This study was conducted using the sex pheromone trap to find out the seasonal phenology of the black cutworm and sod webworm in the golf course. The attracted number to the traps of the black cutworm and sod webworm varied by year, and there were also differences between regions. Overall, black cutworm occurrence peaked between late May to early June, late June to mid-July, and mid-August to mid-September. In addition, sod webworm showed peak occurrence from late June to early July, mid-July, and late September to mid-October. Black cutworms were more attracted to the cone trap than the delta trap. Black cutworm had a higher incidence of 2nd generation, and sod webworm had a large amount of 3rd generation. Effectively control the two pests on the golf course, it is thought that it is necessary to devise a management method through accurate monitoring.
녹색콩풍뎅이(Popillia quadriguttata)의 화학적 방제와 골프장의 금잔디(Zoysia matrella) 및 새로운 기주의 피해
이동운(Dong-Woon Lee),추호렬(Ho-Yul Choo),신흥균(Hong-Gyun Shin),최병귀(Byung-Gui Choi),이근식(Kun-Sik Lee) 한국잡초학회·한국잔디학회 2003 Weed & Turfgrass Science Vol.17 No.1
녹색콩풍뎅이(Popillia quadriguttata)는 우리나라 골프장의 중요 해충 중의 하나이다. 녹색콩풍뎅이 성충은 활엽수나 초본류의 잎을 먹고 유충은 잔디의 뿌리를 가해한다. 녹색콩풍뎅이 성충의 화학적 방제를 위하여 골프장 잔디 해충방제용으로 고시된 earbarl+phosalone WP,chlorifob+) diflubenzuron WP, chlorpyrifos-methyl EC,deltamethrin EC, ethofenprox WP. etofenprox + diaBinon WP. etofenprox +tebufe<br/> nozide EC, fenitrothion EC, imidacloprid SC, pyraclofos WP, tralomethrin EC의 녹색콩풍덩이 성충에 대한 효과를 실내와 온실, 야외에서 조사한 결과, 실내와 온실실험에서 carbary+phosalone WP, chlorpyrifos+diflubenzuron WP, etofenprox + diaBinon WP, fenitrothion EC가 기준량에서 녹색콩풍뎅이 성충에 대하여96% 이상의 치사율을 보였고 field 실험에서는 carbaryl 40+phosalone 20% WP와 fenitrothion 50% EC 처리에서 녹색콩풍뎅이 성충의 보정사충율이 각각 95.2%와 80.9%였다. 전착제 첨가는 carbaryl+phosalon 20% EC를 제외하고는 약효의 증대와 상승을 나타내었다. 경남 진해 용원골프장의 조경수인 칸냐(Canno generolis)와 경기도 군포의 안양 베네스트골프장에의 조경수인 살구나무(Prunus ameriaca var. ansu)와 자두나무(P. salicina)에서 녹색콩풍뎅이에 의한 피해가 확인되어 녹색콩풍뎅이의 기주식물은 총 19과26속 29종이 된다. 2002년 10월과 2003년 3월에 안앙베네스트골프장 페어웨이와 러프의 금잔디(Zoysia matrella)에서는 녹색콩풍뎅이의 유충에의하여 피해를 받는 것이 확인되었다. 녹색콩풍뎅이 유충의 피해를 받은 금잔디는 황화되거나 시들음 증상이 있었고, 이듬해 봄에는 잔디의 회복이 지연되었다. <br/> Popillia quqdriguttata is a serious insect pest in Korean golf courses. The adult feeds on leaves of latifoliate trees and herbaceous plants while the larva feeds on roots of turf grass. Thus, control of P. quadriguttata adults was tried with registered insecticides in golf courses in Korea. The insecticides used in the experiments were carbaryl + phosalone WP, chlorpyrifos + diflubenzuron WP, chlorpyrifos-methyl EC, deltamethrin EC, ethofenprox WP, etofenprox + diazinon WP, etofenprox+tebufenozide EC, fenitrothion EC, imidacloprid SC, pyraclofos WP, and tralomethrin EC. Mortalities of P. quadriguttata were over 95% in carbaryl + phosalone WP, chlorpyrifos+diflubenzuron WP, etofenprox+ diazinon WP, and fenitrothion EC at petri dish and in greenhouse. In the field test, corrected mortality of P. quadriguttata was 95.2% and 80.9% in carbaryl 40% + phosalone 20% WP and fenitrothion 50% EC, respectively. Spreading agent enhanced toxic effect of used insecticides to P. quadriguttata adults except carbaryl + phosalon 20% EC.<br/> P. quadriguttata adult was firstly observed to feed on leaves of Canna generalis at the Yongwon golf club in Jinhae, Gyeongnam and Prunus ameriaca var. ansu and P. salicina at the Anyang Benest golf club in Gunpo, Gyeonggi. Therefore, host plants of P. quadriguttata became 29 species of 26 genera in 19 families. Zoysia matrella at the fairway and roughs of Anyang Benest golf club was damaged by P. quadriguttata larvae in Octomber, 2002 and not recovered in April, 2003. Damaged turfgrass became yellowish and wilted and that retarded recovering in the following spring.
