The amount of Metcalfa pruinosa was higher in Cheonan and Geumsan, which are adjacent to Chungbuk province and in Taean, Dangjin, Asan, Cheonan adjacent to Gyeonggi province. These results demonstrate that M. pruinosa has spread from Chungbuk and Gyeonggi to Chungnam.
As a result of investigating the spatial distribution characteristics of M. pruinosa eggs using SADIE, in 2017, the aggregation index(Ia) of 1.406 was close to the concentration distribution but in 2018, Ia of 1.102 was close to the random distribution. These results confirm that pests have spread throughout Chungnam.
As a result of investigating the hosts that M. pruinosa larvae preferring, the results showed that most host preference with 38 species and 30 species in Asteraceae and Rosaceae, respectively. When the degree of occurrence was divided into four stages, the plants with the highest occurrence degree of 4 were Aralia elata, Styrax japonica, Ziziphus jujuba, Prunus cerasifera and Robinia pseudoacacia, in woody plant, and Rhododendron indicum, Rumex japonicus, Helianthus annuus, Humulus japonicus, and Cirsium japonicum in herbaceous plant. These plants can be used as a chemical substance that can attract larvae and adults before the laying of eggs. Therefore, we plan to utilize these plants to select incentives by studying behavioral responses of M. pruinosa.

The citrus flatid planthopper, Metcalfa pruinosa is one of the invasive insect species in South Korea. M. pruinosa is a broad polyphage damaging over 200 plant species including ginseng, although there is a difference in preference. We selected six insecticides that showed high mortality in ginseng field such as emamectin benzoate EC, sulfoxaflor SG, etofenprox EW, cypermethrin EC, thiacloprid SC and pyrifluquinazon SG. In addition, a method to attract and kill M. pruinosa by treating pesticides on attractive plants (e.g., corn, perilla) with high preference was also tested. The control effect varied from 10 to 80% depending on the distance between forest and farmland. These methods can be used for the control of M. pruinosa in the ginseng farm when the PLS (Positive List System) is fully implemented in 2019.

갈색날개매미충은 기주 범위가 넓고, 효과적 방제가 어려운 해충으로 알려져 있으며, 향후 더 큰 피해를 유발할 수 있는 해충으로 지목되고 있다. 경북지역의 안동과 의성에서 3월부터 9월까지 4개 지점을 선정하여 갈색날개매미충의 월동란이 산란된 월동기주를 중심으로 월동란 부화 시점 및 부화 후 약충에서 성충까지 그리고 다시 월동란 산란까지의 패턴을 모니터링하였다. 각 지점의 환경조건 및 수목류 군락의 조성은 조금씩 차이가 있으나 충분한 산란흔이 있었다. 1령 약충은 5월 중하순부터 하순까지 나타났고 산수유나무, 매실나무에서 가장 먼저 확인되었으며, 이후 수목류에서의 밀도증가 양상은 매실나무에서 더 빠르게 진행되었다. 그리고 2령 약충 까지는 기주식물에 인접한 수목류로의 이동한 모습도 일부 관찰되었다. 그러나 6월 중순경에는 3령 약충의 기주식물 주변 초본류로의 이동이 관찰되었으며, 월동란에서의 부화 후 1회차 이동분산으로써, 주로 상부에서 하부로의 점프를 통한 이동으로 판단된다. 이는 새순 부위가 경화된 월동 기주식물에서 경화되지 않은 초본류의 새순으로의 이동으로써, 특정한 초본류에 집중되지 않고 넓은 범위에 산재하여 분포하였다. 4령 약충 시기에는 주변 특정 초본류와 목본류 새순에 집중적으로 분포하는 패턴을 보이기도 하였다. 7월경에는 성충이 관찰되었으며, 이는 2회차 분산이 진행되는 시점으로 판단된다. 이후 8월 중순까지 지속해서 밀도 감소가 이뤄지던 월동 기주에서의 밀도 감소 상태가 증가 추세로 전환되었다. 그리고 9월 상순경에는 2018년 월동기주에서의 성충밀도 증가와 교미 행동 및 1년생 가지에서의 산란흔이 관찰되었다. 산란흔의 집중도는 산수유나무와 매실나무가 다른 수목류보다 높았으며, 이는 모니터링이 진행된 모든 지점에서 공통된 패턴임을 확인할 수 있었다.

For the setting of control timing, the number of overwintering eggs on host plants and population density of Metcalfa pruinosa nymphs and adults was surveyed in the three peach orchards. According to a survey of the overwintering eggs density (∅2~3㎝, 20㎝ branches) of M. pruinosa on host plants, 221.8 in Mugunghwa trees, 189.3 Oak trees, and 152.7 Acacia trees, and 57.0 Peach showed the number of eggs laid. Examined peach branches within the 50cm (∅1~5cm) was not found population densities of M. pruinosa nymphs and adults, and it was also very low in the sticky trap. The peak density of the adult was highest at 5.4 per trap on August 7 after being first investigated on July 16 in a string wrap survey, and then decreased.
In the peach orchard, it is judged that the control of the M. pruinosa is due to be 20 days after the end of the insect hatching, and that distribution of host plants is more important in the outside region than inside region.

붉은불개미는 세계 100대 침입외래 해충 중의 하나로 우리나라에서는 관리 해충으로 1996년도에 지정되었다. 2017년 9월28일 부산항 감만 부두에서 국내 최초로 발견된 후, 2018년에 부산항, 평택항 과 인천항에서 발견이 되었고, 9월18일에 대구의 아파트 공사장에서 내륙에서는 처음으로 발견이 되었다. 대구에서 발견된 붉은불개미도 아파트 건설을 위하여 중국에서 수입한 석재에 혼합되어 수입된 토양과 식물체와 같이 혼입된 것으로 추측이 된다. 그러므로, 현재까지 국내에서 붉은불개미가 번식을 하여 토착화되었다는 증거는 없다. 현재까지 붉은불개미에 대한 종 판명은 전문가에 의한 형태적인 분류가 대부분이다. 그래서, 붉은불개미에 대한 확증을 위해서는 채집된 개체를 검역기관으로 이송하여 분자진단을 실시해야 하므로, 최소 이틀의 시간이 필요하다. 현재 항원항체 반응을 이용한 붉은불개미 진단 키트가 해외에서 개발되어 판매되고 있지만, 낮은 민감도로 최소 3~5개의 충체가 필요한 실정이다. 현재 판매되고 있는 진단키트가 가지는 문제점은 이를 대신할 새로운 키트의 개발이 필요함을 보여주고 있다. 신속한 붉은불개미의 검역현장에서 진단을 가능하게하기 위한 노력 중의 하나로 우리는 붉은불개미의 복부에서 발현되는 유전체에 대한 연구를 수행하였다. 본 발표에서는 그에 대한 현재까지의 연구 진행과 결과를 설명하도록 하겠다.

Climatic similarity between a native region and a target area is the first step to be considered for judging an invasive risk of alien species. In this study, we compared climate of the origin of Solenopsis invicta with that of South Korea. Match Climate application in CLIMEX software was used to simulate Composite Match Index (CMI) which quantitatively evaluated climatic similarity between two locations. We selected a native city (Cordoba in Argentina) of Solenopsis invicta and compared its climate with the current climate in South Korea. Result showed that climatic similarity is higher in Gyeongsangbuk-do area including Andong and Pohang, When only comparing climate during April to October, CMI was generally increased, but areas with the highest CMI was decreased.

Whitefly (Hemiptera: Aleyrodidae) pests, including the tobacco whitefly, Bemisia tabaci, and the greenhouse whitefly, Trialeurodes vaporariorum, are economically important in agriculture. With the annual growth of the domestic fresh fruit export market, various quarantine treatment methods are being used to export strawberries of better quality. The objective of the present study was to evaluate the effects of gamma rays on the development and reproductive sterility of B. tabaci and T. vaporariorum. In both species, the eggs were completely inhibited from hatching at 50 Gy, and the emergence of 3rd instar nymphs was completely suppressed at 150 Gy. Some adult B. tabaci and T. vaporariorum spawning occurred at 100 Gy and 70 Gy, respectively; however, at these irradiation levels, F1 hatchability was completely inhibited. Dosimetry results showed that the penetrating power of gamma ray in the strawberry-filled box was the lowest at the mid-box position. Therefore, B. tabaci and T. vaporariorum were placed in the middle of the strawberry-filled box and irradiated. A gamma-ray irradiation of 100 Gy suppressed the development and reproduction of eggs and adults in both B. tabaci and T. vaporariorum. However, the development of 3rd instar nymphs was inhibited at 300 Gy for B. tabaci and 200 Gy for T. vaporariorum. Our data suggest that at least 300 Gy should be used for the control of these two types of whitefly for strawberry export.

Red imported fire ant (Solenopsis invicta) is a notorious pest which has caused damage of human life. Recent expansion of its habitat due to climate change has threatened where it cannot live before. South Korea has been exposed to its invasion, alerting early assessment of potential distribution of Solenopsis invicta. The objective is, hence, to predict potential distribution of Solenopsis invicta in South Korea based on climatic suitability. CLIMEX software was used for predicting Solenopsis invicta distribution in 2020 under RCP 8.5 climatic change scenario. Result showed that climates in coastal areas, Daegu, and Jeju island would be suitable for inhabitation of Solenopsis invicta. This results suggested that the risk of Solenopsis invicta invasion might be increased with the current climate change.

This study investigated the fumigant activity of phosphine (PH3) on 2 kinds of mealybug (Pseudococcus longispinus and P. orchidicola (Hemiptera: Pseudococcidae)) adults and nymphs. All of the two mealybugs adults showed higher LCT99 values than nymphs, and P. longispinus showed higher tolerance than P. orchidicola in a 12 L desiccator. The absorption of phosphine on 13 nursery plants showed 12.2~41.5% difference depending on the plant. All of the mealybugs treated with phosphine 2 mg/L in 0.5 m3 fumigation chamber for 4 h showed 100% fumigant activity, except P. longispinus adult (approximately 90% at bottom part). However, when the exposure time was increased to 24 h, all of them showed 100% mortality. In the treatment of 10 m3 container, the 24 h treatment of phosphine showed 100% mortality to P. longispinus and P. orchidicola adults and nymphs. In all the experiments, no phytotoxicity of phosphine observed on 13 plants until 1 month after treatment.

We conducted quarantine insect species diversity monitoring using DNA barcoding with 517 lepidopteran samples that were obtained from quarantine inspections of foreign vessels entering Korea. The DNA barcode of each sample was treated as a molecular operational taxonomic unit (MOTU). For species delimitation and species identification of the analyzed samples, we applied a 2% cutoff rule and then identified with using BLAST of NCBI GenBank and BOLD System ver. 3.0. Consequently, 517 analyzed samples were delimited as 214 putative species across 20 families. Of these 214 putative species 145 (368 samples) were considered taxonomically identified if the closest BLAST match was no more than 2% different. Therefore the number of samples that were identified to the species level was relatively low, at approximately 71%. 115 of the 145 species were known in Korea. Of the 30 species that were not known in Korea, three, i.e., Noctua pronuba (Noctuidae), Orthosia hibisci (Noctuidae), and Pieris brassicae (Pieridae), were checked as ‘Regulated pests’ in Korea. We suggest that the three regulated pest species could be prevented from being introduced to Korea if monitoring of the vessels that pass the navigation route that contains these three species is performed consistently. Therefore, we suggest that the monitoring of quarantined insect pest enables the prevention of the introduction of alien species.

선박이나 컨테이너로 수출입되는 곡류 및 박류는 검역용 훈증제인 메틸브로마이드(이하 MB)와 인화수소(이하 PH3)를 사용하는데, 처리 온도/수용비/선적방식에 따라 충분한 배기시간을 필요로 한다. 현장에서 배기시간 미설정으로 검역관 및 방제기술자에게 훈증제 TLV(Threshold Limit Value)-TWA(Time Weighted Average) 기준 이상의 농도에 노출될 위험이 있으므로, 소독 전, 후 작업자 안전을 고려하여 각 훈증제 별 작업자 안전기준에 적합한 배기시간이 설정되어야 한다. 따라서, 실내 훈증상에서 곡류(쌀, 대두) 및 박류(대두박, 주정박)를 대상으로 현행 소독처리기준으로 소독 후 탈착되는 가스농도를 측정해 MB 1 ppm, PH3 0.3 ppm 수준 이하로 감소되는 배기시간을 조사하였다. 조사결과 TLV-TWA 기준이하의 수준으로 감소되는데 필요한 배기시간은 주정박/대두박/대두에 MB가 처리된 경우는 모두 30시간, 쌀에 PH3가 처리된 경우는 30분이 소요되는 것을 확인하였다.

It is uncommon to fumigate the live plants in quarantine. Ethyl formate (EF) fumigation was carried out in a 0.275 m3 chamber in laboratory for 12 h (over-night) to evaluate the mortality of 4 insect pests and to evaluate the phyto-toxic effect on their host plants. The tested doses were 1, 1.5 and 2 mg/L EF with or without nitrogen gas (N2). The phytotoxicity was evaluated 7 days post-fumigation based on the damage index (DI) scaling 0-4. Mortality >80% were recorded against thrips, whitefly and aphid in all the EF or EF + N2 treatments. Two-spotted spider mite was highly tolerant (<20% mortality at the highest dose tested) to EF. Except for perilla and sesame (DI = 4), EF was non-toxic to other vegetable crops at 1.5 mg/L EF. However, 1.5 mg/L EF+N2 increased DI by 3 for tomato, watermelon and green pumpkin. This new method fumigating live plants certainly demands lots of further experiments to ensure its practical application in farm level. (Supported by PJ0133562018, RDA)

Ethyl formate (EF) fumigation under green house condition is a new concept. Its concentrations inside and surrounding of the glass house (GH) and vinyl house (VH) were evaluated for 4 h (during daytime) and 12 h (during nighttime) after fumigation along with the evaluation of post-fumigation EF concentrations. The cumulative EF concentration × time (Ct) value of the 6 sampling positions in VH were 22.67 and 17.53 g·h/m3, respectively for day and night fumigation, which were 2.62 and 4.53 g·h/m3 respectively for day and night application in GH. The EF level (PPM) outside the VH and GH as well as after 20-min post fumigation were < 50 ppm revealing its safety level as its’ threshold limit value (TLV) is 100 ppm. The new technology using liquid EF fomulation could be a key option in smart-farm technologies in future. (Supported by PJ0133562018, RDA)

우드펠렛은 가정용, 상업용, 산업용 등으로 사용되며 특히 화력발전소에서 석탄 대용으로 수입량이 급증하여 연간 약 2,400만톤 가량 수입되고 있는 상황이다. 우드펠렛 검역훈증제로 기존에는 메틸브로마이드(이하 MB)가 최근까지 사용되어져 왔으나, MB의 높은 흡착률과 우드펠렛의 과도한 수용비로 인해 최종가스농도 기준에 미치지 못하여 재투약하는 사례가 빈번히 발생해 문제가 되어져왔다. 이를 해결하기 위해 농림축산검역본부에서는 올해 초 MB와 포스핀을 병행으로 처리하는 방식의 소독처리기준을 신설하였다. 새로운 소독처리기준이 설정됨에 따라 배기시 안전한 배기시간 수준을 설정하기 위해 병행처리 후 수착과 탈착되는 가스농도를 조사하였다.
실내 훈증상에 우드펠렛을 채우고 약제 처리한 결과 각 훈증제의 TLV(Threshold Limit Value)-TWA(Time Weighted Average) 기준이하로 농도가 감소되는 배기시간은 25℃일 때 MB는 120시간, 포스핀은 6시간으로 측정되었고 15℃일 때 MB는 186시간, 포스핀은 19시간으로 측정되었다.

In order to accumulate the ecological information of Drosophila suzukii for export negotiations of domestic strawberry, we weekly monitored occurrence of D. suzukii at three strawberry fields located in Gok-seong, Dam-yang and Hwa-sun using the best combination of trap and attractant from November 2017 to May 2018, the period of strawberry production. Monitoring was carried out at three sites (a hill located 150 meter distant to greenhouse, outside greenhouse and inside greenhouse) in Gok-seong. Drosophil suzukii was trapped at three short periods from November to the beginning of December, from the end of December to the beginning of January, and from April in a hill. At outside greenhouse, D. suzukii was trapped at two short periods from November to the early December and the beginning of May. In inside greenhouse, it occurred once after May 24th. Gok-seong data can be summarized as more occurrence for longer period as the distance to greenhouse increases. Dam-yang occurred once in a short period inside greenhouse and hill, respectively on May. In case of Hwa-sun, D. suzukii did not trapped in whole trapping sites during trapping period, except for the surrounding grape and peach cultivation areas at the end of November. Summarized, no occurrence periods are from November 20th, 2017 to May 14th, 2018 inside greenhouse; from December 11th, 2017 to May 3rd, 2018 outside greenhouse; and from January 8th, 2018 to April 12th, 2018 on a hill. In connection with strawberry culture, the D. suzukii tends to occur at the beginning and the end of the strawberry production period. We expect this result can serve as a helpful data for export negotiation for quarantine.

Cymbidium flower is mainly grown for exportation to China and Japan, but detection of a few pests including the cotton aphid, Aphis gossypii (Hemiptera: Aphidae), necessitated post-harvest treatment for casual exportation. Thus, we irradiated electron beam to cotton aphids occurring in cymbidium to establish post-harvest method for casual exportation of the flowers. For cymbidium, six categories of product quality were examined after eight different doses were irradiated (100, 200, 300, 400, 500, 600, 800 and 1,000 Gy). One thousand Gy to cymbidium caused an extreme deterioration only in vase life in both colors compared to control (0 Gy). In the case of cotton aphids, adult longevity decreased from 11.23 (100 Gy) to 4.70 (400 Gy) when four different doses were irradiated (100, 200, 300, and 400 Gy), with control being an average of 20.89 days. The numbers of total first instar nymph produced per adult was not significantly differed among five doses (2.21 ~ 2.74 individuals), but was substantially lower compared to control (an average of 51.46; P < 0.0001). Live F1 nymphs did not develope to adults at all five doses, except for a single nymph at 100 Gy, which was dead right after emergence. The results of probit analysis indicated that majority of adults required 3.33 ~ 7.55 days for 90% mortality at 200 Gy and higher, but at 100 Gy it required 41.56 days. Therefore, higher than 100 Gy might be required for complete control of adult cotton aphids and their F1.
