The principal active component produced by highly attractive senesced host banana leaves, Musa spp., for the banana weevil, Cosmopolites sordidus, is shown by coupled gas chromatography-electroantennography (GC-EAG), coupled GC-mass spectrometry (GC-MS), chemical synthesis and coupled enantioselective (chiral) GC-EAG to be (2R,5S)-theaspirane. In laboratory behaviour tests, the synthetic compound is as attractive as natural host leaf material and presents a new opportunity for pest control.
高度吸引性衰老寄主香蕉叶（Musa spp.）为香蕉象鼻虫（Cosmopolites sordidus）产生的主要活性成分，通过气相色谱-触角电位联用（GC-EAG）、气相色谱-质谱联用（GC-MS）、化学合成以及对映选择性（手性）GC-EAG 联用表明为（2R,5S）-theaspirane。在实验室行为测试中，该合成化合物与天然寄主叶片材料一样具有吸引力，为害虫防治提供了新的机会。
