The emergence times of the following species of Carabid beetles were investigated in a long day of LD 18/6: Agonum assimile Payk., Pterostichus angustatus Dft., P. nigrita F., and P. oblongopunctatus F.The hatching of the beetles was examined by means of an automatically controlled photorecorder.In one series of experiments flash-light was used for taking photographs. In a second series photographs were taken only during the light phase by the light of a fluorescent tube of the same type as used for the illumination of the breeding chamber.Both series of experiments produced no evidence of the existence of a typical emergence rhythm in the four Carabid species. In each species the number of beetles hatched per hour is slightly greater during the phtophase than during the scotophase. This difference was statistically significant only for P. angustatus. From this it is concluded that some Carabid species have a latent capability for synchronization of emergence by a light dark change.The sexes of P. angustatus show no difference in the distribution of their emergence times.
在18/6的长日照条件下，对以下步甲科甲虫物种的羽化时间进行了研究：拟同色步甲（Agonum assimile Payk.）、狭翅步甲（Pterostichus angustatus Dft.）、黑步甲（P. nigrita F.）和长圆斑步甲（P. oblongopunctatus F.）。通过自动控制的光记录器检查甲虫的孵化情况。在一系列实验中，使用闪光灯拍照。在另一系列实验中，仅在光照阶段利用与饲养室照明所用相同类型的荧光灯管的光线进行拍照。这两个系列的实验均未提供证据表明这四种步甲科物种存在典型的羽化节律。在每个物种中，每小时羽化的甲虫数量在光照阶段略多于黑暗阶段。这种差异仅对狭翅步甲具有统计学意义。由此得出结论，一些步甲科物种具有通过明暗变化同步羽化的潜在能力。狭翅步甲的雌雄在羽化时间分布上没有差异。
