꽃노랑총채벌레 성충에 대한 4종 식물정유(muguet flower, patchouli, pennyroyal, spearmint)의 훈증효과를 조사하였다. 그들 중 100%의 훈증효과를 나타낸 정유는 pennyroyal oil과 spearmint oil 이었다. 두 정유에 대한 주요 구성성분을 GC와 GC/MS로 분석한 결과, pennyroyal oil은 pulegone(100.0%), spearmint oil은 ${eta}-myrcene(3.5%)$, limonene(12.1%), carvone(85.4%)이 주요 구성성분으로 나타났다. 이 성분의 훈증독성 시험결과 carvone과 pulegone은 $1{mu}{ell}/45m{ell}$ air의 약량에서 100%의 높은 훈증독성을 나타내었다.
Fumigant toxicity of four plant essential oils (muguet flower, patchouli, pennyroyal, spearmint) were tested against the adults of western flower thrips, Frankliniella occidentalis. Among them, pennyroyal and spearmint oils showed 100% mortality at $1{mu}{ell}/45m{ell}$ air dose. Through the constituent analysis using GC and GC-MS, we confirmed that main constituents of pennyroyal oil were pulegone(100.0%), and spearmint oil were $eta-myrcene(3.5%)$, limonene(12.1%), carvone(85.4%). Among them, carvone and pulegone showed 100% fumigation at $1{mu}{ell}/45m{ell}$ air dose, respectively. It can concluded that two oils are potential control agents against F. occidentalis.
