The present study aims to examine the role of photoreception by the compound eyes and ocelli in photoperiodism. An experiment with surgical removal of the compound eyes suggested that in Armadillidium vulgare the compound eyes are involved in the photoperiodism. Larvae of Leptocarabus kumagaii lost the sensitivity to photoperiod by ablation of the stemmata. However, the mortality after operation was high and the number of insects was not enough for conclusion.The role of the compound eyes in nymphs of Blattela nipponica and Poecilocoris lewisi is still unclear. In Plautia crossota stali, the compound eyes play a major role in the photoperiodism, although photoreceptors other than the compound eyes can also receive photic information for photoperiodism. Furthermore, Dianemobius nigrofasciatus and Protophormia terraenovae, in which the compound eyes have been shown to be the principal photoreceptor for photoperiodism, used both extraretinal photoreceptors and compound eyes for its entrainment of the circadian activity rhythm.Therefore, it is suggested that extraretinal photoreceptors in the brain is widely distributed and that compound eyes, extraretinal receptors or both types of photoreceptor are operative depending on the species.

本研究旨在探讨复眼和单眼的光感受在光周期现象中的作用。一项手术切除复眼的实验表明，在普通犰狳中，复眼参与了光周期现象。 Leptocarabus kumagaii 的幼虫通过茎的消融而失去了对光周期的敏感性。但术后死亡率较高，且昆虫数量不足以下结论。复眼在小蠊和Poecilocoris lewisi若虫中的作用尚不清楚。在Plautia crossota stali中，复眼在光周期中起主要作用，尽管复眼以外的光感受器也可以接收光周期信息。此外，Dianemobius nigrofasciatus 和 Protophormia terraenovae 的复眼已被证明是光周期的主要光感受器，它们同时使用视网膜外光感受器和复眼来控制昼夜节律。因此，表明大脑中视网膜外光感受器分布广泛，复眼， 视网膜外受体或两种类型的光感受器都起作用，具体取决于物种。
