The sex pheromone of Scrobipalpula absoluta (Meyrick) (Lepidoptera: Gelechiidae) was identified as a 92:8 mixture of (3E,8Z,11Z)-3,8,11-tetradecatrienyl acetate (1) and (3E,8Z)-3,8-tetradecadienyl acetate (2) through mass spectrometric investigation of the dimethyl disulphide derivatives of excised sex pheromone glands. It is the first time that this method was used for triple unsaturated straight chain
真叶假单胞菌(Meyrick)(鳞翅目:鞘翅目)的性信息素被鉴定为(3 E,8 Z,11 Z)-3,8,11-十四碳三烯基乙酸酯(1)和(3 E, 8 Z)-3,8-十四碳二烯基乙酸酯(2)通过质谱研究切除的性信息素腺体的二甲基二硫化物衍生物。这是第一次将这种方法用于三重不饱和直链分子。化合物(2)被鉴定为新的信息素组分。两种鉴定出的化合物的合成混合物在风洞实验中被证明具有吸引力。
