Calling song and walking activity patterns of the Australian field cricket Teleogryllus commodus were simultaneously recorded in LD and LL at constant temperature. The results were analysed with respect to their circadian structure: (1) Circadian properties were expressed more clearly in singing than in walking, with cases approaching arrhythmicity in the latter. Still, (independent) circadian control was proven for walking as in most cases the phase response of the recorded data was different from that of synthetic data produced by a model using the calling song as the only circadian source. (2) The phase angle difference between singing and walking rhythm (psi SIN/WAL) was usually smaller in LD than in LL, where values in the range of 180 degrees prevailed (Fig. 7). However deviations often occurred, during which the slopes of the instantaneous phase positions of singing and walking were different for several cycles, indicating individual periods. (3) Internal dissociation was also found following the exposure to 6-h pulses of low temperature. (4) After unilateral blinding of one compound eye during the last larval instar, which leads to splitting of the calling song rhythm, internal desynchronization was found between singing and walking. Additional removal of one optic lobe resulted in a common period and an abnormal psi SIN/WAL close to zero. (5) We interpret the results as follows: temporal calling song and walking activity patterns are controlled by the same compound circadian mechanism. Its bilaterally distributed pacemakers (Wiedenmann 1983) may dissociate under certain experimental conditions revealing their individual oscillatory properties in either singing or walking.
在恒温条件下，同时记录了澳大利亚田野蟋蟀Teleogryllus commodus的鸣叫歌声和行走活动模式，记录条件为12小时光照/12小时黑暗（LD）和持续光照（LL）。针对其昼夜节律结构对结果进行了分析：（1）昼夜节律特性在鸣叫中比在行走中表现得更明显，后者存在接近无节律性的情况。不过，仍证明行走受（独立的）昼夜节律控制，因为在大多数情况下，记录数据的相位响应与仅将鸣叫歌声作为唯一昼夜节律源的模型生成的合成数据不同。（2）鸣叫和行走节律之间的相位角差（ψSIN/WAL）在LD条件下通常比在LL条件下小，在LL条件下180度左右的值占主导（图7）。然而，经常会出现偏差，在此期间，鸣叫和行走的瞬时相位位置斜率在几个周期内不同，表明存在个体周期。（3）在暴露于6小时低温脉冲后也发现了内部分离。（4）在最后一龄幼虫期单侧摘除一只复眼后，鸣叫歌声节律出现分裂，发现鸣叫和行走之间存在内部分步。额外摘除一个视叶导致出现共同周期，且ψSIN/WAL异常接近零。（5）我们对结果的解释如下：鸣叫歌声和行走活动的时间模式受同一复合昼夜节律机制控制。其双侧分布的起搏器（Wiedenmann，1983）在某些实验条件下可能会分离，从而在鸣叫或行走中揭示其个体振荡特性。
