A female-produced sex pheromone for the pecan nut casebearer, Acrobasis nuxvorella Neunzig, has been identified from pheromone gland extracts of calling female moths. The compound (9E,11Z)-hexadecadienal [(9E,11Z)-16:Ald] was identified by coupled GC-EAD and retention time matches with a synthetic standard on four capillary GC columns of different polarities. Corroboration of the identification of (9E,11Z)-16:Ald by other analytical chemistry methods was not possible due to the minute quantities of pheromone extracted (< 1 picogram/female). In field studies, gray rubber septa impregnated with 100 micrograms of synthetic (9E,11Z)-16:Ald were attractive to male moths, whereas higher and lower doses were less attractive. The homologous (9E,11Z)-15:Ald was also slightly attractive while the more highly conjugated analogues, (9E,11Z,13Z)- and (9E,11Z,13E)-16:Ald, were not.
从处于求偶期的雌性山核桃果蛀蛾（Acrobasis nuxvorella Neunzig）的性信息素腺体提取物中，已鉴定出一种由雌性产生的性信息素。通过气相色谱-触角电位联用技术（GC-EAD）以及在四根不同极性的毛细管气相色谱柱上与合成标准品进行保留时间匹配，鉴定出该化合物为（9E,11Z）-十六碳二烯醛[（9E,11Z）-16:Ald]。由于提取的性信息素量极少（<1皮克/雌性），无法用其他分析化学方法对（9E,11Z）-16:Ald的鉴定结果进行确证。在田间研究中，用100微克合成的（9E,11Z）-16:Ald浸渍的灰色橡胶隔片对雄性蛾具有吸引力，而更高和更低剂量的吸引力较小。同源的（9E,11Z）-15:Ald也有轻微吸引力，而共轭程度更高的类似物（9E,11Z,13Z）-和（9E,11Z,13E）-16:Ald则没有吸引力。
