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.

本研究旨在检查复合眼和ocelli在光周期中的光感受的作用。通过手术去除化合物的实验表明，在Armadillidium v​​ulgare中，化合物的眼睛参与光周期。 Leptocarabus kumagaii的幼虫通过消融茎的敏感性失去了对光周期的敏感性。然而，手术后的死亡率很高，昆虫的数量不足以结论。复合眼在Blattela Nipponica和Poecilocoris Lewisi的若虫中的作用尚不清楚。在plautia crossota stali中，复合眼在光周期中起着主要作用，尽管除复合眼睛以外的其他光感受器也可以接收光周期性的光学信息。 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,视外受体或两种类型的光感受器取决于物种的作用。
