Two biologically active macrolides were isolated from Porapak Q-captured beetle and frass volatiles ofCryptolestes turcicus (Grouvelle) and identified spectroscopically as (Z,Z)-5,8-tetradecadien-13-olide (I) and (Z)-5-tetradecen-13-olide (II). Natural I was active alone and was synergized by inactive II. The pheromones were male-produced but attractive to both sexes. Pheromone production increased dramatically when insects were aerated on a food source. Pure (R)- and (S)-I were inactive, but mixtures of (R)- and (S)-I were active, the first reported instance of enantiomeric synergism in the Cucujidae.
从土耳其扁谷盗（Cryptolestes turcicus ）Porapak 捕获的甲虫和粪便挥发物中分离出两种具有生物活性的大环内酯，并通过光谱法鉴定为（Z,Z）-5,8-十四碳二烯-13-内酯（I）和（Z）-5-十四碳烯-13-内酯（II）。天然 I 单独具有活性，并与无活性的 II 协同作用。这些信息素是由雄性产生的，但对雌雄两性都有吸引力。当昆虫在食物源上通气时，信息素的产生会急剧增加。纯（R）-和（S）-I 没有活性，但（R）-和（S）-I 的混合物具有活性，这是 Cucujidae 中首次报道的对映体协同作用的实例。
