Fifteen insect species have been identified as olive pests through a survey conducted in olive orchards on Jeju island from 2019 to 2022. The occurrence and fruit damage caused by Lepidopteran and hemipteran were significant severity. Among the moths, the order in which the population was large was as follows: Alpita nigropunctalis, Aterpia circumfluxana, Homona magnanima, and Adoxophyes honmai. These lepidopteran species primarily caused damage to leaves, but P. nigropunctalis inflicted severe damage to the fruits by feeding on the inside. Three stink bugs, namely Plautia stali, Halyomorpha halys, and Chinavia hilaris, were commonly observed and responsible for damaging olive furits. Chrysomphalus bifasciculatus and Pseudaulacaspis pentagona were found to occur and damaged fruit in non-controlled orchard. Prociphilus oleae, which is being recognized for the first time in Korea, and Ricania shantungensis discovered for the first timein olive orchard. Saissetia olea, a quarantine pest, was found in one farm, but subsequent pesticide spraying resulted in their elimination. Although severe damage was inflicted upon the olives, no perforated pests were found during the survey.
2019년부터 2022년까지 제주도 올리브(olive, Olea europaea)에서 발생하는 해충을 조사한 결과, 총 15종의 해충이 확인되었다. 이중 나방류와 노린재류의 발생과 과실 피해가 매우 심했다. 나방류는 수수꽃다리명나방(Palpita nigropunctalis), 큰점애기잎말이나방(Aterpia circumfluxana), 차잎밀아나방(Homona magnanima), 차애모무늬잎말이나방(Adoxophyes honmai) 순으로 많이 발생하였다. 나방류 해충은 주로 잎을 가해했지만, 수수꽃다리명나방은 과실피해도 심하게 유발하였다. 노린재류로는 갈색날개노린재(Plautia stali), 썩덩나무노린재(Halyomorpha halys), 풀색노린재(Chinavia hilaris)가 주로 발생하여 과실 피해를 유발하였다. 깍지벌레류인 갈색깍지벌레(Chrysomphalus bifasciculatus)와 뽕나무깍지벌레(Pseudaulacaspis pentagona)는 무방제 시 과실에도 발생하여 피해를 주었다. 진딧물과 해충은 국내 미기록종인 올리브면충(신칭, Prociphilus oleae)만이 발생하였고, 갈색나무매미충(Ricania shantungensis)도 올리브에 처음 발생이 확인되었다. 국내 미기록종인 올리브철모깍지벌레(신칭, Saissetia olea)은 발견되었으나 방제후 더이상 발생하지 않았다. 이외 천공성 해충이 올리브에 심각한 피해를 유발하였으나, 종은 확인되지 않았다.
