Abstract

The insecticidal activities of the Eucalyptus dives and Thymus vulgaris oils were assessed against Plodia interpunctella and Tribolium castaneum in granary. Insecticidal activities of the E. dives oil showed 100 % mortality against P. interpunctella larvae for 72 h and P. interpunctella adults for 3 h. Moreover, the T. vulgaris oil was observed with 100 % mortality against T. castaneum larvae for 120 h and T. castaneum adults for 120 h. These results indicate that it may be possible to control P. interpunctella and T. castaneum through the application of E. dives and T. vulgaris oils in granary.

본 연구에서는 정부양곡창고내에서 유칼립투스 페퍼민트와 타임에서 추출한 정유성분을 이용한 화랑곡나방과 거짓쌀도둑거저리의 살충 실증실험을 진행하였으며, 정부양곡창고내에서 정유성분을 이용한 저곡해충 방제의 이용 가능성을 확인하였다. 그 결과, 유칼립투스 페퍼민트 정유성분에 의하여는 화랑곡나방 유충은 72시간 내에 100 % 사충율이 나타났으며, 성충은 3시간 내에 100 % 사충율이 나타났다. 타임에서 추출한 정유성분에 의하여는 거짓쌀도둑거저리 유충은 120시간 내에 100 % 사충율을 보였으며, 성충은 120시간 내에 100 % 사충율을 보였다. 이러한 결과는 정부양곡창고에서 화랑곡나방과 거짓쌀도둑거저리를 방제하기 위해서 친환경적이고 안전한 오일성분을 이용하여 정부양곡창고내 저곡해충에 대한 방제 가능성을 보여준다.
