The cyclamen mite, Phytonemus pallidus (Banks) (Acari: Tarsonemidae) has been considered as a lower priority pest compared to broad mite, Polyphagotarsonemus latus mostly because the cyclamen mite had rarely occurred in economic plants in Korea. This is the first report of field occurrence of the cyclamen mite on economic crop, strawberry. From the summer cultivation of strawberry in Samcheok, Gangwon province, infestation of the cyclamen mites was confirmed in 2010. Infested leaves and sepals turned discolored on the tip and stunted growth producing blotched appearance, distorted leaves, and malformed fruits. Infestation was found on late July and spreaded quickly until mid September, but only in imported Sharott variety not in domestic Goha variety. Released Amblyseius swirkii survived and were found in the damaged fruits even 1 month after release.

A simulation study on SCR (Steam Carbon dioxide Reforming) process in gas-to-liquid (natural gas to Fischer-Tropsch synthetic fuel) process was carried out in order to find optimum reaction conditions for GTL (gas-to-liquid) process reaction. Optimum SCR operating conditions for synthesis gas to FT (Fischer-Tropsch) process were determined by changing reaction variables such as feed temperature and pressure. During the simulation, overall synthesis process was assumed to proceed under steady-state conditions. It was also assumed that physical properties of reaction medium were governed by RKS (Redlich-Kwong-Soave) equation. SCR process was considered as reaction models for synthesis gas in GTL proess. The effect of temperature and pressure on SCR process H₂/CO ratio and the effect of reaction pressure on SCR reaction were mainly examined. Simulation results were also compared to experimental results to confirm the reliability of simulation model. Simulation results were reasonably well matched with experimental results.

김정환,변영웅,김용헌,김황용,Kim, Jeong-Hwan,Byoun, Young-Woong,Kim, Yong-Heon,Kim, Hwang-Yong 한국응용곤충학회 2007 한국응용곤충학회지 Vol.46 No.1

아메리카잎굴파리 외부기생봉인 굴파리좀벌의 온도별 알, 유충, 번데기 발육기간과 성충의 산란수, 기주체액 흡즙수, 성충수명, 저온 저장력 등을 조사하였다. 굴파리좀벌의 알기간, 유충기간, 번데기 기간은 $25^{\circ}C$에서 각각 1.3일, 4.5일, 6.3일이었다. 성충의 산란수, 기주체액 흡즙수, 성충수명은 $25^{\circ}C$에서 각각 305.3마리, 657.0마리, 25.1일이었다. 아메리카잎굴파리 유충 영기별 굴파리좀벌의 산란선호성과 흡즙선호성을 조사한 결과 각각 90.2%와 82.8%가 3령 유충에 집중되었다. 굴파리좀벌의 저온저장에 따른 50% 생존기간은 꿀물 20%희석 용액을 제공할 경우 $5^{\circ}C,\; 10^{\circ}C,\;15^{\circ}C$에서 각각 180일, 150일, 90일이었다. 굴파리좀벌 저온저장 후 산란수는 저장기간 30일, 70일, 140일에서 각각 190.8개, 104.0개, 89.4개였다. Experiments have been performed to investigate biological characteristics of Diglyphus isaea (Walker), an ectoparasite of Liriomyza trifolii (Burgess). At $25^{\circ}C$, development time of D. isaea was estimated as 1.3 days for eggs, 4.5 days for larvae and 6.3 days for pupae. Adult longevity was 25.1 days, and a female adult could lay 305.3 eggs throughout its lifetime. Number of L. trifolii parasitized or killed by the wasp was 962.2 individuals/adult. Most of all parasitized or killed larvae were identified as third instar. With 20% honeyed water as food source, half of the adults could survive 180 days at $5^{\circ}C$, 150 days at $10^{\circ}C$, and 90 days at $15^{\circ}C$. After storing at $10^{\circ}C$ with absolute honey for 30 days, 70 days and 140 days, a female adult in room temperature laid eggs 190.8 individuals, 104.0 individuals and 89.4 individuals, respectively.

김정환,변영웅,김용헌,박창규,Kim Jeong-Hwan,Byeon Young-Woong,Kim Yong-Heon,Park Chang-Gyu 한국응용곤충학회 2006 한국응용곤충학회지 Vol.45 No.1

시설재배 꽈리고추, 피망에 발생하는 꽃노랑총채벌레와 오이에 발생하는 오이총채벌레의 생물적 방제를 위하여 작물별로 천적인 으뜸애꽃노린재(Orius strigicollis) 방사구, 오이이리응애(Amblyseius cucumeris) 방사구, 무방사구를 두어 총채벌레 밀도억제 효과를 조사하였다. 으뜸애꽃노린재에 의한 총채벌레의 밀도억제효과 산출 식은 (무처리구 밀도-처리구 밀도)/무처리구 밀도 ${\times}$ 100으로 하여 조사시기별로 각각 구한 결과, 꽈리고추에서 으뜸애꽃노린재 방사구는 최하 14.3%에서 최고 99.5%, 오이이리응애 처리구는 $12.9{\sim}38.3%$였고, 피망에서 으뜸애꽃노린재 처리구는 $21.6{\sim}98.3%$, 오이이리응애 처리구는 $17.1{\sim}87.0%$였다. 오이에서 으뜸애꽃노린재 처리구는 $61.2{\sim}74.4%$, 오이이리응애 처리구는 $90.4{\sim}97.4%$를 보였다. 따라서 봄 작기 꽈리고추와 피망에 발생하는 꽃노랑총채벌레는 발생 초기 으뜸애꽃노린재를 주당 $5{\sim}6$마리를 $3{\sim}6$회로 나누어 방사하고, 가을 작기 오이에 발생하는 오이총채별레는 발생초기 오이이리응애를 주당 100마리씩 4회 정도 방사하면 효과적임. Effectiveness of Orius strigicollis (Poppius) and Amblyseius cucumeris (Oudemans) as natural enemies against thrips were evaluated on greenhouse green pepper, sweet pepper and cucumber respectively. Control efficacy was calculated by the formula, $(D_{control}-D_{treatment})/D_{control}{\times}100$, where $D_{control}$ is the average density of thrips on the plots in which any natural enemy was not released and $D_{treatment}$ is the average density of thrips on the plots in which natural enemies were released respectively. As a result, control efficacies of O. strigicollis against Frankliniella occidentalis (Pergande) on green pepper and sweet pepper were $14.3{\sim}99.5%$ and $21.6{\sim}98.3%$, respectively. In addition, control efficacy of it against Thrips palmi Kany on cucumber was 61.2-74.4%. Control efficacies of A. cucumeris against F. occidentalis on green pepper and sweet pepper were $12.9{\sim}38.3%$ and $17.1{\sim}87.0%$, respectively. Control efficacy of it against T. palmi on cucumber was $90.4{\sim}97.4%$. Field evaluation showed that the prompt applications of natural enemies were effective to reduce the density of thrips. In detail, to control F. occidentalis effectively on green pepper and sweet pepper in spring season, five to six individuals of O. strigicollis per crops should be released three to six times continuously. To control T. palmi effectively on cucumber in autumn, more than 100 individuals of A. cucumeris per crop should be released four times repeatedly.

최만영,김정환,변영웅,김황용,김용헌,Choi, Man-Young,Kim, Jeong-Hwan,Byeon, Young-Woong,Kim, Hwang-Yong,Kim, Yong-Heon 한국응용곤충학회 2010 한국응용곤충학회지 Vol.49 No.4

담배나방 알(HAs)을 기주로 사육된 명충알벌(TC)을 담배나방(HAs-HAs)과 왕담배나방(HAs-HAr) 알에, 줄알락명나방(CC) 알을 기주로 사육된 TC를 왕담배나방(CC-HAr) 알과 담배나방(CC-HAs)에, 왕담배나방(HAr) 알을 기주로 사육된 TC를 왕담배나방(HAr-HAr)과 담배나방(HAr-HAs)에 대한 기생률, 발육기간, 우회율, 번식량을 실험실 조건(온도 $25{\pm}2^{\circ}C$; 습도 50~70%; 광기간 16L-8D)에서 조사하였다. TC는 직전에 어떤 기주에 사육했는가에 따라 시험 기주에서 나타나는 발육반응이 다르다는 것을 알 수 있었으며, 흔히 직전기주와 시험기주의 크기에 의해 발육기간 우회율, 기생률, 번식량이 차이를 보였으며, 가장 큰 차이를 보인 것은 기생률과 번식량인 것으로 나타났다. 기생률은 가장 낮은 CC-HAr의 $10.1{\pm}2.05%$에서 가장 높은 HAr-HAs의 $47.0{\pm}2.09%$로 나타나 처리 간에 유의한 차이를 보였으며, 우회율에서도 유사한 경향을 보였다. 발육기간은 직전기주의 크기가 가장 작고 시험기주의 크기가 가장 큰 CC-HAr처리에서 가장 짧았다. 처리에 따른 TC의 번식량은 HAr-HAs에서 가장 높았으며($93.9{\pm}6.87$마리), 가장 낮은 처리는 CC-HAs($18.4{\pm}6.36$마리)였다. The parasitism, development time, hatchability, and progeny production of Trichogramma chilonis(TC) females developed in eggs of Helicoverpa assulta (HAs), Cadra cautella (CC), and Helicoverpa armigera (HAr), respectively, were compared with those developed in reciprocal eggs at constant temperatures of $25{\pm}2^{\circ}C$ and relative humidity of 50~70% under 16L-8D. Developmental performances of TC reared in each of the three hosts on the following hosts(host tested) appeared differently, and were affected most by the size of the proceeding hosts and test host. Among the parameters parasitism and progeny production were affected more than others. Parasitism was significantly different between the treatments, lowest in CC-HAr($10.1{\pm}2.05%$) and highest in HAr-HAs($47.0{\pm}2.09%$), and the hatchability showed similar pattern. Development time as well was shortest in the CC-HAr where previous host is smallest and test host is biggest. The highest number of progeny production of TC was observed in HAr-HAs($93.9{\pm}6.87$ wasps), and the lowest was CC-HAs($18.4{\pm}6.36$ wasps).

With the comparison of native Orius strigicollis (Poppius) to European O. laevigatus (Fieber), we investigated biological characteristics such as developmental period, fecundity, life span, predation ability, and augmentation after release. Experiments were carried out at five temperature condition, $15^{\circ}C\;20^{\circ}C,\;25^{\circ}C\;30^{\circ}C$, and $35^{\circ}C$. In the case of O. strigicollis, egg period was $3.1{\sim}14.9$ days (hatchability: $46.7{\sim}88.2%$), and developmental period of nymphs was $9.4{\sim}42.8$ days (survival rate: $2.4{\sim}96.5%$). Fecundity at each temperature was 28.1, 107.9, 123.6, 127.3, and 18.1, respectively. Life span of adults was 63.4, 40.1, 22.1, 18.3, and 11.0 days, respectively. In the case of O. laevigatus, egg period was $3.1{\sim}13.5$ days (hatchability: $65.0{\sim}89.9%$), and developmental period of nymphs was $9.3{\sim}42.0$ (survival rate: $4.3{\sim}80.6%$) days. Fecundity at each temperature was 101.8, 218.6, 224.5, 219.5, and 15.7. Life span of adults was 70.6, 66.4, 32.6, 34.5, and 7.3 days, respectively. In long-day condition (16L:8D), fecundity of O. strigicollis and O. laevigatus was 105.8 $(18^{\circ}C){\sim}142.4(25^{\circ}C)$ and 109.5 $(18^{\circ}C){\sim}191.5(25^{\circ}C)$, respectively. In short-day condition (10L:14D), fecundity of them was 1.0 $(18^{\circ}C){\sim}31.8(25^{\circ}C)$ and 63.0 $(18^{\circ}C){\sim}198.8(25^{\circ}C)$, respectively. Daily prey consumption of second instar Frankliniella occidentalis was 14.3 and 10.9, respectively. In greenhouse, density of O. strigicollis begins to increase from mid May and peaked about early July (1.8 individual/flower), while that of O. laevigatus begins to increase from mid March and peaked about early June (6.6 individual/flower).

김황용,김정환,손병관,조점래,이용휘,김용헌,최만영,Kim, Hwang-Yong,Kim, Jeong-Hwan,Son, Byeong-Gwan,Cho, Jum-Rae,Lee, Yong-Hwi,Kim, Yong-Heon,Choi, Man-Young 한국응용곤충학회 2009 한국응용곤충학회지 Vol.48 No.2

살충제를 사용하지 않고 성페로몬을 활용한 대량포획기술만으로, 10,000 $m^2$ 규모의 대형 토마토 유리온실에서 단위면적 당 60원/$m^2$의 방제비용으로 담배거세미나방을 효과적으로 방제하는데 성공하였다. 대량포획을 위해 온실 내부에 500 $m^2$당 1개씩 성페로몬 트랩을 설치하고, 담배거세미나방 유입을 막기 위해 온실 외각에 20 m 간격으로 성페로몬 트랩을 설치하는 방법을 이용하여 담배거세미나방을 방제할 수 있었다. 시험기간 동안 트랩당 평균 400마리 이상의 담배거세미나방이 유살되었다. Without pesticide applications, mass-trapping by sex pheromone was successful to control Spodoptera litura (Fabricius) in a large scale tomato glasshouse (10,000 $m^2$) at a low cost of 60 won/$m^2$. Pheromone traps were placed both inside and outside of the glasshouse. Inside the glasshouse traps were installed in a regular space, one trap per 500 $m^2$, to catch the moths that were present in the glasshouse, and traps were also set outside of the glasshouse, at intervals of ca. 20 m, to prevent the moths from invading the glasshouse. In the experiment, more than 400 S. litura were captured per trap.
