The validity of the oscillator-clock hypothesis for photoperiodic time measurement in insects and mites is questioned on the basis of a re-interpretation of available experimental evidence. The possible role of the circadian system in photoperiodism in arthropods is critically reviewed. Apart from the outcome of kinetic experiments, based on diel and non-diel light/dark cycles, evidence from various genetic and physiological experiments is discussed in relation to the oscillator-clock hypothesis. The conclusion is that photoperiodic time measurement in insects and mites is performed by a non-circadian 'hourglass' clock. Experimental evidence suggests a non-clock role for the circadian system in the photoperiodic mechanism of insects and mites.
基于对现有实验证据的重新解读，昆虫和螨类光周期时间测量的振荡器时钟假说的有效性受到质疑。对节肢动物昼夜节律系统在光周期现象中的可能作用进行了批判性综述。除了基于昼夜和非昼夜光/暗周期的动力学实验结果外，还讨论了来自各种遗传和生理学实验的证据与振荡器时钟假说的关系。结论是，昆虫和螨类的光周期时间测量是由一个非昼夜的“沙漏”时钟完成的。实验证据表明，昼夜节律系统在昆虫和螨类的光周期机制中具有非时钟作用。
