식물기생선충은 식물에 기생하여 식물의 생장을 저하시키거나 심할 경우 식물의 고사를 일으키는 주요 병원 체의 하나이다. 이들 선충은 수입 식물을 통해 국내로 유입될 수 있으며, 이로 인해 식물의 생장이 저하되거나 식물이 죽는 등의 실제적 피해를 야기할 수 있다. 생강은 한국의 대표 음식인 김치를 비롯한 다양한 요리와 음료, 전통약재 등에 사용되는 중요한 식약재료이며, 그 가치와 수요가 매우 높다. 최근 10년(2014-2023년) 동안 종구로 써 사용되는 재식용 생강의 수입량은 총 31,740톤이었는데, 수입 생강 원산지의 대부분은 중국으로써 최근 10년 간 수입량의 99.99%를 차지했다. 동기간 검역처분 내역은 합격 수량이 1,090건(27,637톤), 폐기 수량은 222건 (4,102톤)이었다. 폐기 처분을 받는 주용 원인을 분석해보면, 관리급 선충 검출이 139건, 종구에 흙이 부착된 경우 가 26건 등이었다. 앞으로도 농림축산검역본부는 수입 재식용 생강에 대한 실험실정밀검역을 통해 우리나라의 농업과 자연환경에 위해를 가할 수 있는 식물기생선충의 차단을 위해 최선의 노력을 다하고자 한다.

Dysmicoccus brevipes (Cockerell), Dysmicoccus neobrevipes Beardsley and Pseudococcus longispinus (Targioni-Tozzetti) are widely-distributed pests that feeds on many economically important hosts, particularly tropical fruits and ornamentals. The potential distribution of these mealybug pests into South Korea remains a primary concern because of their high incidence in interceptions screened during inspection. Hence, these species prompted a modelling effort to assess their potential risk of introduction. Potential risk maps were developed for these pests with the CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s was projected based on the RCP 8.5 climate change scenario. Results show that D. brevipes, D. neobrevipes and P. longispinus have little potential for invasion in the exterior environment of South Korea due to high cold stress in the 2020s. However, for D. brevipes and P. longispinus, 3 and 86 locations in Jejudo, were predicted to be marginally suitable for this pest under future climate factors, respectively. In that respect, the results of these model predictions could be used to prepare a risk-based surveying program that improves the probability of detecting early D. brevipe, D. neobrevipes and P. longispinus populations.

We analyzed trends of ants intercepted on imported plants and lumber over the past 30 years, using data extracted from the Pest Information System (PIS). There were 1,629 cases of about 112 species (5 subfamilies, 45 genera) from planting plants such as Asparagales, Alismatales, and Saxifragales, and 2,217 cases of about 86 species (7 subfamilies, 42 genera) from lumbers such as square lumber, pellets, and solid wood. For intercepted trends by continent, Asia was the most frequently detected at 91%, followed by Europe at 1% and North America at nearly 1%. Among Asian countries, Malaysia (27%) represented the highest number of interceptions, followed closely by Indonesia at 26%.

The current inspection count for imported grains is 37,072. The scientific management of stored grain, which includes methodical pest identification and control procedures, is highly prioritized in the nations that export these grains. International documents on stored grain pests include a thorough description of all life phases, including mites and larvae, as well as methodical treatment techniques. They are more valuable than domestic manuals because of their comprehensive coverage and methodical management strategies. There is lack of genetic resources and photographs since the identification of stored grain pests in the domestic have been based on data from before 2017. During the course of 13 years(2010-2022) 1,469 incidences of stored grain pests were detected. Of these, 7 orders 34 families and 81 species had cases where the identification was confirmed down to the species level, for a total of 963 cases. This number shows that about 18% of the domestic quarantine site’s stored grain pests are not species-identified. Objectives in this study are to present genetic barcode data, high-resolution photoes for classification and identification, and information on international stored grain pest management techniques. Building on this, a new identification manuals for stored grain pests might be created, which would improve the site’s taxonomic identification levels.

With the increasing indroduction and spread of invasive quarantine pests, accurate diagnosis of pests detected in quarantine sites has become crucial. DNA barcoding, a standardized method that complements morphological analysis for rapid and precise species identification, is actively researched worldwide. In this study, we established a molecular biological identification system for major pests encountered during the import and export of agricultural and forestry products. By analyzing the DNA barcode sequences of pests collected domestically and those detected in quarantine inspections, we compiled genetic information for 1,292 individuals representing 472 species, 108 families across 11 insect orders. Among these, order Lepidoptera had the highest diversity, with 251 species across 27 families. We also secured barcodes for 52 species, 24 families in order Hemiptera, and 70 species, 20 families in order Coleoptera. By constructing a comprehensive biological foundation and database for various pests detected in quarantine sites, we aim to enhance the quarantine system by enabling rapid and accurate identification of invasive pests, thereby blocking early.

In countries without strong biosecurity systems, Khapra beetle, Trogoderma granarium poses a continuing threat to agriculture. Even when quarantine laws exist, the risk is greater if one of the world's most serious pests becomes introduced to imported stored grain. The rate of Khapra beetles introduced is rising sharply with increased transport, trade, travel, and tourism between countries and continents. Species identification is usually the key to success in Khapra beetle control programs. Countries that export/import grains, such as Australia, Canada, Russia, Korea and USA, must ensure that their ports, grain storage facilities, and transportation systems are free of khapra beetle. Researchers so far developed effective quarantine treatments and eradication strategies to deal with khapra beetle infestations that occur upon import at inland port. Khapra beetle introductions are likely to be impacted by a variety of factors, including trade flow and quarantine laws. In this study, we provide an overview of the current global quarantine laws, invasions of khapra beetle, and its control strategies.

최근 소셜미디어 이용이 심리적 웰빙에 미치는 영향이 부각되고 있으나 어떤 요소가 소셜미디어 상에서의 관계 의 질을 예측할 수 있는지에 대한 연구는 상대적으로 드물다. 본 연구는 머신러닝 기법을 이용하여 COVID-19로 인한 자가격리 동안 인스타그램 활동과 외로움, 우울 등의 심리 상태가 소셜미디어 상에서의 관계의 질을 예측할 수 있는지 알아보고자 하였다. 성인 95명을 대상으로 자가격리 중과 자가격리 해제 후 시점에서 외로움, 인스타그 램 활동, 소셜미디어 상에서의 관계, 우울 등에 대해 자기보고식 설문에 응답하도록 하였다. 그 후, 다차원 척도법과 표상유사성분석, 분류분석을 각 시점에 대해 수행하였다. 다차원척도법 결과, 1차원에서 인스타그램 이용 시간과 우울이 다른 변인들과 구별되었으며, 2차원에서 외로움과 수동적 이용이 다른 변인들과 구별되었다. 그 후 소셜미 디어 상에서의 관계의 질의 고,저 집단에 대해 표상유사성분석을 실시한 결과, 소셜미디어 상에서의 관계의 질이 높은 집단은 낮은 집단보다 자가격리의 영향을 더 많이 받는 것으로 나타났다. 분류분석 결과에서도 소셜미디어 상에서의 관계의 질 예측 변인이 사회적 고립의 여부에 따라 달라지는 것으로 나타났다. 따라서 본 연구의 결과는 사람들이 사회적 고립 상황에 있지 않을 때 인스타그램 이용 변인과 심리적 변인이 소셜미디어 상에서의 관계를 더 잘 예측할 수 있음을 시사한다.

2015년부터 2022년도까지 6개목(딱정벌레목, 노린재목, 나비목, 벌목, 파리목, 총채벌레목) 곤충들에 대해서 식물검역현장 검출실적과 국내 보고된 미기록종을 분석하였다. 해당기간 동안 국경검역에서 6개목 곤충은 총 45,084건이 검출되었다. 같은 기간 국내에서는 총 545종이 미기록종 으로 보고되었으며, 이중 9종은 국경검역에서도 검출된 것으로 확인되었다. 검역현장에서는 딱정벌레목, 총채벌레목, 노린재목이 높은 검출률을 보 였으며, 국내 미기록종 중에서는 벌목이 176종으로 가장 많이 보고되었다. 본 연구를 통해 침입압력(국경검역 검출)과 실제 침입(국내 미기록종 발 견) 사이에 비동시성이 확인되었다. 향후 보다 장기적인 분석이 필요할 뿐만 아니라 지속적인 식물검역시스템 개선이 필요할 것으로 판단된다.

Purpose: To determine whether artificial -intelligence quarantine robots can positively contribute to environmental management in medical institutions. We conducted in-depth interviews to understand the experiences of hospitalized patients receiving environmental management from such robots. Methods: Data were collected during March 20~May 20, 2023. individual in-depth interviews were conducted with 15 hospitalized patients, who could provide specific details of their experience of receiving environmental management from a quarantine robot. Results: Qualitative content analysis identified four themes, including “First encounter with an amazing and new quarantine robot,” “Efficiently performs non-face-to-face quarantine work in hospitals,” “Problems with quarantine robots,” and “Recommendations for improving the functionality of quarantine robots in medical institutions so quarantine robots and humans can coexist.” Conclusion: Currently, quarantine robots have limited functionality, and additional research is needed to identify various other functions in consideration of future infectious disease situations and the level of quarantine appropriate in a hospital.

We analyzed trend of plants (40 items) on imported seedlings using the Pest Information System (PIS) for the past 20 years. 530 species (9 order 336 genus) were found among 40 items on imported seedlings including Rosaceae, Arecaceae, Crassulaceae, and Fabaceae. Hemiptera were the most expected to be detected pest as 52%, followed by Coleoptera as 16%, Lepidoptera as 11%, and Diptera as 8% in potential detection rate. For prohibited pests, Tephritidae are the most common pests as 86% in approximately 60 prohibited species, including Bactrocera dorsalis, and Bactrocera tryoni in Diptera and Cydia pomonella in Lepidoptera.

The utilization of methyl bromide (MB) for quarantine purposes has been hampered by its designation as an ozone-depleting substance under the Montreal Protocol. The International Plant Protection Convention's (IPPC) call for alternatives to MB and a reduction in its usage. There is an urgent need to explore and implement substitutes. Despite some substitute agents like EDN being developed for wood, EDN has been limited due to various factors such as occupational risks. This study focuses on evaluating the efficacy of Sulfuryl Fluoride (SF) as a viable alternative fumigant against Reticulitermes speratus, one of major wood destroying pests. Experimental trials conducted at ambient temperature (23°C) revealed promising results, with SF demonstrating LCT50 and LCT99 values of 30.87 mg·h/L and 42.53 mg·h/L, respectively. Under low-temperature conditions (5°C), SF remained effective but with slightly higher LCT50 and LCT99 values of 151.62 mg·h/L and 401.90 mg·h/L, respectively. The penetration test, conducted using R. speratus-infested pine wood cubes, further highlighted SF's efficacy, with LCT50 and LCT99 values of 31.59 mg·h/L and 53.34mg·h/L at 23°C, indicating powerful penetration capabilities. When tested at a loading ratio of 90% (v/v) at 5.0mg/L for 24 hours in a 500L chamber as a middle-scale trial, SF achieved a 100% mortality, showing its potential as a suitable replacement for MB. These findings suggest that SF could open new markets as an MB substitute and enhance safety at quarantine sites when applied to imported and exported timber.

우리나라 식물방역법은 검역병해충으로부터 국내 농업 및 자연환경을 보호하고자 규제병해충(검역병해충, 잠정규제병해충, 규제비검역병해충) 관련 위험평가, 식물검역기술개발계획, 식물검역 절차 및 방법, 검역결과 에 따른 처분, 규제병해충 예찰 및 방제 등에 관한 다양한 법적 절차 등을 규정하고 있다. 하지만, 식물검역병해충 을 어떻게 취급하여야 할 지에 관한 내용은 없다. 따라서 식물방역법이 추구하는 목적을 달성하기 위하여서는 ① 검역병해충을 어떻게 취급하여야 할 지를 규정하여야 하며, ② 검역병해충을 취급하는 시설(검사, 연구, 운송, 보관 등) 기준을 설정하고, ③ 검역병해충 취급 시설을 인증하고, 주기적인 재인증 기준을 설정하여야 한다. 이를 위하여 먼저 식물방역법에 검역병해충 취급시설 등에 관한 규정을 신설하고, 시행령, 시행규칙에 반영한 후에 ① 검역병해충 취급요령 ② 검역병해충 취급시설 기준 ③ 검역병해충 취급시설 인증기준 등의 고시를 제정하여 야 한다. 이를 위하여 식물병해충 관련 학계의 의견 반영이 가장 중요하다.

Research on alternative fumigants to replace methyl bromide (MB), a harmful ozone-depleting substance and highly toxic pesticide, began in 2007. Initial tests focused on using ethyl formate for fruits and EDN for wood. Subsequently, alternative techniques were developed for a total of 94 plant types using ethyl formate, EDN, and phosphine, demonstrating Korea's superior performance compared to other countries, especially in practical applications. However, when it comes to wood products, the primary users of methyl bromide, EDN is scarcely used due to concerns about worker safety. An emerging alternative to MB is sulfuryl fluoride (SF), widely employed in North America to control wood-damaging pests like termites. SF's advantages include a lower boiling point and higher vapor pressure, making it effective against wood pests. Yet, certain bark beetle eggs require higher doses and longer treatment periods, resulting in established international standards (e.g., 120g/m3 for 48 hours at 20℃), posing challenges for field applications. Recently, the APQA initiated basic research to apply SF to wood. They are assessing SF's effectiveness against various wood-destroying pests, including termites, bark beetles, and long horn beetles, while also evaluating the feasibility of mixed treatments to reduce dosage. Once SF fumigation standards are established, it is expected to significantly reduce methyl bromide use in commonly used wood types, contributing to ozone layer protection and enhancing fumigation work safety.
