초록

현재 급속하게 퍼져가고 있는 외래해충이면서 돌발해충인 갈색날개매미충 유충 및 성충의 천연살충제를 개발하기 위하여 엽침지법과 직접분무법을 이용하여 쑥(Artemisia vulgaris), 딜(Anethum graveolens), 자몽(Citrus paradisi), 티트리(Melaleuca alternifolia), 카제풋(Melaleuca leucadendron), 네롤리(Neroli bigarade) 및 만수국(Tagetes erecta)에서 추출한 정유성분을 이용하여 살충효과를 실험하였다. 갈색날개매미충 유충에 대한 살충효과는 엽침지법을 이용하여 72시간에 7종 정유성분을 각각 처리하였을 때에 쑥, 딜, 자몽, 티트리, 카제풋, 네롤리 및 만수국 정유성분 순서별로 반수치농도($LC_{50}$)는 각각 251.02, 387.31, 286.21, 353.54, 275.64, 424.55, $165.68mg/cm^2$ 이며, 직접분무법을 이용한 갈색날개매미충 성충의 반수치사농도는 각각 278.31, 402.11, 306.11, 379.64, 298.22, 459.56, $183.21mg/cm^2$으로 살충활성을 보였다. 이러한 연구결과를 바탕으로 만수국의 정유가 갈색날개매미충 유충 및 성충에 대하여 친환경 살충제로써 적용 가능성을 보여주며, 더 나아가 식물체 정유성분을 이용한 외래해충 방제 기술을 응용한 제품의 다양화에 기여할 것이다.

The insecticidal toxicities of seven essential oils against Ricania sp. nymph and adults, newly recorded pest, were evaluated using leaf-dipping and spray methods. At 72 h exposure time, the $LC_{50}$ values of the essential oils of Artemisia vulgaris, Anethum graveolens, Citrus paradisi, Melaleuca alternifolia, Melaleuca leucadendron, Neroli bigarade and Tagetes erecta were 251.02, 387.31, 286.21, 353.54, 275.64, 424.55, $165.68mg/cm^2$ when using the leaf dipping method against Ricania sp. nymphs, and 278.31, 402.11, 306.11, 379.64, 298.22, 459.56, $183.21mg/cm^2$ when using the spray method against Ricania sp. adults, respectively. These results indicate that the essential oil of the Tagetes erecta can be potentially used as new natural insecticidal agents against Ricania sp. nymph and adults.
