鼓膜器官在蛱蝶科蝴蝶中广泛存在,这些耳朵的形态具有很大的变异性。这种变化如何反映听觉生理学的差异目前尚不清楚。这项研究提供了第一次检查的听觉器官在黄昏猫头鹰蝴蝶,卡利戈eurilochus。我们检查了C的调谐和灵敏度。应用激光多普勒测振仪和细胞外神经生理学方法,对耳蜗的一个听器(Vogel氏器)进行了研究。我们证明了C.如鼓膜的振动和相关神经分支的生理反应所证实的,eurilochusear对声音有反应,并且对1和4kHz之间的频率最敏感。与其昼夜活动的亲戚,Morphopeleides,C。eurilochus具有较窄的频率范围和较高的听觉阈值。解释这黄昏蝴蝶的听力功能的假设进行了讨论。
Tympanal organs are widespread in Nymphalidae butterflies, with a great deal of variability in the morphology of these ears. How this variation reflects differences in hearing physiology is not currently understood. This study provides the first examination of hearing organs in the crepuscular owl butterfly,Caligo eurilochus. We examined the tuning and sensitivity of theC. eurilochushearing organ, called Vogel’s organ, using laser Doppler vibrometry and extracellular neurophysiology. We show that theC. eurilochusear responds to sound and is most sensitive to frequencies between 1 and 4 kHz, as confirmed by both the vibration of the tympanal membrane and the physiological response of the associated nerve branches. In comparison to the hearing of its diurnally active relative,Morpho peleides,C. eurilochushas a narrower frequency range with higher auditory thresholds. Hypotheses explaining the function of hearing in this crepuscular butterfly are discussed.
