The sex pheromone of the hibiscus flower borer Rehimena surusalis (Walker) (Lepidoptera: Crambidae) was analyzed by gas chromatography with electroantennographic detection (GC-EAD) and GC-mass spectrometry (GC/MS). Three EAD-active components were found in crude pheromone gland extracts of calling females. GC/MS and GC analyses using synthetic chemicals and derivatization of the extracts identified three components as (10E,12Z)-hexadeca-10,12-dienal (E10,Z12-16:Ald,), (10E,12E)-hexadeca-10,12-dienyl acetate (E10,Z12-16:OAc), and (3Z,6Z,9Z)-tricosa-3,6,9-triene (Z3,Z6,Z9-23:HC). In field tests, male moths were strongly attracted to a ternary blend of E10,Z12-16:Ald, E10,Z12-16:OAc, and Z3,Z6,Z9-23:HC at a ratio of 1:5:14, but single and binary blends showed only weak or no attraction.
采用气相色谱-触角电位检测联用技术（GC-EAD）和气相色谱-质谱联用技术（GC/MS）对木槿花蛀虫Rehimena surusalis（Walker）（鳞翅目：草螟科）的性信息素进行了分析。在处于求偶状态的雌虫的粗性信息素腺体提取物中发现了三种具有触角电位活性的成分。通过使用合成化学品以及对提取物进行衍生化处理后的GC/MS和GC分析，确定这三种成分分别为（10E,12Z）-十六碳-10,12-二烯醛（E10,Z12-16:Ald）、（10E,12E）-十六碳-10,12-二烯基乙酸酯（E10,Z12-16:OAc）和（3Z,6Z,9Z）-二十三碳-3,6,9-三烯（Z3,Z6,Z9-23:HC）。在田间试验中，雄蛾对E10,Z12-16:Ald、E10,Z12-16:OAc和Z3,Z6,Z9-23:HC以1:5:14的比例组成的三元混合物有强烈的趋性，但单一成分和二元混合物仅表现出微弱的趋性或无趋性。
