Abstract

Locomotor activity rhythms of dark stock flies of Drosophila melanogaster kept in complete darkness for 700 to 1340 generations were examined. The stock was established by the late Prof. S. Mori in November 1954 to investigate long-term effects of darkness on organisms. The activity of flies was recorded under three types of light conditions: DD after LD12:12, and DD after exposure to a 3.5 h (P3) or 7.5 h (P7) light pulse. In all of these conditions, the experimental dark flies exhibited clear circadian rhythms similar to those of control light flies. We compare our results with those of various studies on troglobites.

摘要

对在完全黑暗环境中饲养700至1340代的黑腹果蝇暗系果蝇的运动活动节律进行了检查。该品系由已故的S. Mori教授于1954年11月建立，用于研究黑暗对生物体的长期影响。在三种光照条件下记录果蝇的活动：在LD12:12之后的DD，以及在暴露于3.5小时（P3）或7.5小时（P7）光脉冲后的DD。在所有这些条件下，实验暗系果蝇表现出与对照明系果蝇相似的清晰昼夜节律。我们将我们的结果与各种关于洞穴生物的研究结果进行了比较。
