2015년부터 2022년도까지 6개목(딱정벌레목, 노린재목, 나비목, 벌목, 파리목, 총채벌레목)에 대해서 식물검 역현장 검출실적과 국내 미기록종을 분석 하였다. 총 45,078건이 검역현장에서 검출되었으며, 545종이 새롭게 국내에 보고되었다. 이중 9종은 검역현장에서도 검출된 것으로 확인되었다. 검역현장에서는 딱정벌레목, 총채 벌레목, 노린재목이 높은 검출률을 보였으며, 국내 미기록종 중에서는 벌목이 176종으로 가장 많이 보고되었다. 본 연구는 검출실적과 미기록종과의 관계를 살펴볼 때, 동시간대의 침입압력으로는 설명이 어렵다는 것을 보여 주고 있으며, 이는 지속적인 식물검역시스템 개선이 필요성을 제시한다.

Due to rapid increase of international trade, many invasive and exotic pests have been introduced in Korea. One of typical example is Solenopsis invicta found in harbor and nearby areas unexpectedly triggering alerts of invasive and exotic pests. Practically, critical limitation to identify these species based on morphology exists because of lack of experts, so that it is very important to develop fast and accurate methods to identify these species. Molecular marker is one of candidates for satisfying these requirements of invasive and exotic pests: usually COI gene has been used for identifying insect species efficiently. Here, we developed web-based integrated platform for identifying invasive and exotic pests. As a first step, we collected 71,146 COI sequences from 529 species which are potentially invasive and exotic pests in Korea. In addition, we are collecting their complete mitochondrial genome sequences for evaluating additional marker regions which can be more effective for identifying species. Web-based interfaces are under development to access these raw data as well as bioinformatic analysis function to identify species based on mitochondrial sequences. Our platform will be a fundamental resources not only to identify invasive and exotic pests effectively but also to understand ecology of these species to find anticipative policies to prevent invasion of these species.

The movements of unwanted pests between different continents are being accelerated by the global climate change and ever-increasing international trades, which has also been facilitated by the recent increase of FTA and other trade agreements. Many invasive pests cause serious economic losses and ecological disturbance in invaded rural and natural areas. Since the uncertainty of potential impact of invasive pests, it would be extremely useful if the priority of invasive quarantine pests can be predicted for the efficient surveillance and eradication processes. We are initially analysed national and foreign examples to evaluate the current system of pest prioritization of national quarantine pests. Also here we suggests evaluation platforms for selecting high priority exotic pests.

Korea has been importing large quantities of plant materials from countries annually all over the world. Accordingly,various kinds of pests have been also detected during import inspections. In addition, these days the weather in Koreahas been getting warmer and a number of imported subtropical and tropical crops are being cultivated in greenhouses.In these regards, conducting a monitoring survey by using pheromone traps is required in order to prevent introductionand settlement of invasive species to Korea. we provide a list of insects collected from five types of pheromone trapscollected while monitoring exotic pests over the last seven years. Data from the monitoring surveys of pheromone trapsfrom 2010 to 2016 was extracted from database of the Plant Quarantine Integration System (PQIS) developed by theAnimal and Plant Quarantine Agency (APQA). As a result of our review on the PQIS database, 119 species were identified.The families forming the main groups are Tephritidae, Tortricidae, Camillidae and Cosmopterigidae. We believe that researchersand inspectors in charge of quarantine need to be well aware of the species collected from monitoring traps.

Interception data pertaining to Coleoptera, Hemiptera, Lepidoptera, Diptera, Thysanoptera, and Hymenoptera collected at the Korean quarantine border were cross-checked with incursion data from 1996–2014. Overall, 114,636 interception records of 1,075 species belonging to the six orders were detected, while 33 species were confirmed as incursion species in Korea. Among the 33 species, only 14 (42.42%) were recorded as being intercepted at the quarantine border. These results indicate recent incursion species in Korea are not subject to inspection at Korean border. Among the 33 incursion species, 30 (90.90%) are agricultural pests, and 10 species (30.30%) are Hemiptera. Two factors, green house cultivation and parthenogenesis of exotic species, are suggested as reasons for successfully mounting an incursion into Korea. Taken together, the results of this study revealed that border inspections do not provide useful information to protect against occurrences of exotic species incursion and the current quarantine system needs improvement. In addition, it is necessary to consider how interception data might be collected in the future to improve its predictive power with respect to predicting incursion risk.
