摘要总结了昆虫光周期性的三个组成部分-光周期感受器、光周期钟和激素效应器的解剖位置，并在种间进行了比较。在光周期性光感受器中，视网膜型或视网膜外型或两者都是有效的，并且在视网膜发育和光感受器类型之间没有一般的关系。光周期时钟包括时间测量和计数器系统。目前，人们普遍认为昼夜节律振荡器参与了光周期时钟。最近的几项研究提出了一种可能性，即昼夜节律钟基因timeless在苍蝇的光周期时钟中发挥作用。背侧前脑是光周期控制的成虫、蛹和胚胎滞育的重要内分泌调节区域。在果蝇Protophormia terraenoenopsis中，已经证明了生物钟神经元和背侧前脑中滞育诱导的侧部中不可缺少的神经元之间的神经联系。该神经网络可以提供研究光周期时钟的神经组件所需的访问。
The anatomical locations of three components of insect photoperiodism—the photoperiodic photoreceptor, photoperiodic clock and hormonal effector—are summarized and compared between species. Among photoperiodic photoreceptors, either the retinal or extraretinal types or both are operative, and there is no general relationship between phylogeny and photoreceptor type. The photoperiodic clock comprises time measurement and counter systems. Currently, it is generally accepted that circadian oscillators are involved in the photoperiodic clock. Several recent studies have raised the possibility that timeless, a circadian clock gene, plays a role in the photoperiodic clock in flies. The dorsal protocerebrum has been identified as an important region regulating the endocrine system for adult, pupal and embryonic diapause controlled by photoperiod. In the blow fly Protophormia terraenovae, neural connections between circadian clock neurons and indispensable neurons in the pars lateralis for diapause induction in the dorsal protocerebrum have been demonstrated. This neural network may provide the access needed to investigate the neural components of the photoperiodic clock.
