研究了角蛾性信息素主要成分[(Z，E)-9，11，13-十四碳三烯醛]的模拟物[(Z，E)-7，9，11-十二碳三烯基甲酸酯]的行为和电生理活性。风洞生物测试表明，甲酸盐与自然腺体提取物一样有效，但在唤起源头接触方面明显高于三烯醛或与两种次要信息素成分混合的三烯醛。当以相同剂量放置在枣园的诱捕器中时，含有甲酸盐的分配器在吸引雄性方面与含有三烯醇类的混合诱饵一样有效。单细胞记录显示，至少有两个嗅觉神经元位于角果蛾触角上的长毛状毛中，它们的区别是尖峰幅度。剂量-反应关系表明，从装有至少0.1杯甲酸盐或三烯醛的药筒中喷出，对于引起感受器内的小尖峰细胞或大尖峰细胞的尖峰是必要的。交叉适应研究表明，这两种化合物刺激的是同一个大尖峰细胞。当0.1杯、1杯或10杯甲酸酯或三烯醇发射物刺激大细胞时，诱发的尖峰频率没有显著差异，表明甲酸盐是触角感受器细胞水平上的三烯醛的有效模拟物。
The behavioral and electrophysiological activity of a mimic [(Z,E)-7,9,11-dodecatrienyl formate] of the major sex pheromone component [(Z,E)-9,11,13-tetradecatrienal] of carob moth was assessed. Wind-tunnel bioassays demonstrated that the formate was as effective as natural gland extracts, and significantly more effective than the trienal alone or than the trienal blended with two minor pheromone components, in evoking source contact. Dispensers containing the formate were as effective as trienal-containing blend lures in attracting males when placed at the same dosage in traps in date gardens. Single-cell recordings showed that at least two olfactory neurons, differentiated by spike amplitude, are located in the long trichoid hairs on male carob moth antennae. Dose-response relationships indicated that puffs from cartridges loaded with at least 0.1 mug of the formate or of the trienal were necessary to elicit spiking by either the small- or the large-spiking cell within a sensillum. Cross-adaptation studies demonstrated that both compounds stimulated the same large-spiking cell. The frequencies of spikes evoked from the large cell when stimulated by emissions from 0.1-mug, 1-mug, or 10-mug cartridges of either the formate or the trienal were not significantly different, suggesting that the formate is an effective mimic of the trienal at the antennal receptor cell level.
