用频率为1~33赫兹的双组分信息素脉冲处理棉铃虫、棉铃虫和甜菜夜蛾的雄性触角，时间为20ms。电子触角图的傅立叶分析解决了棉铃虫和甜菜夜蛾以高达33赫兹的频率传递信息素细丝的时间结构，而棉铃虫的信息素细丝以25赫兹的频率传递。对每个物种单独测试的信息素成分在完成混合的灯丝分辨率方面通常是相同的。18、23和28摄氏度的环境温度对灯丝分辨率的影响很小，对18摄氏度的快速脉冲信号的辨别能力较差。这些频率在外周神经系统之外是如何保存的，或者是否保存，这个问题仍然存在。(C)2002爱思唯尔科学有限公司。保留所有权利。
Male antennae of Cadra cautella, Pectinophora gossypiella, and Spodoptera exigua were presented with 20-ms-duration pulses of their two-component pheromone at rates of 1 to 33 Hz. Fourier analyses of electroantennograms resolved the temporal structure of trains of pheromone filaments delivered at up to 33 Hz for C. cautella and S. exigua and 25 Hz for P. gossypiella. Pheromone components tested separately for each species were generally equivalent in filament resolution to complete blends. Ambient temperatures of 18, 23 and 28 degreesC affected filament resolution only slightly, with poorer ability to discriminate rapidly pulsed signals at 18 degreesC. The question of how, or indeed if, such frequencies are conserved beyond the peripheral nervous system, remains. (C) 2002 Elsevier Science Ltd. All rights reserved.
