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.
