测定了拟果蝇成虫羽化昼夜节律的光致相移作用谱。提前相移和延迟相移的作用谱相似；最有效的波长在蓝色区域，在500纳米以上有一个明显的截止。这种相似性表明，相同的感光色素介导了提前相移和延迟相移。
Action spectra were determined for lightinduced phase shifts of the circadian rhythm of adult emergence in Drosophila pseudoobscura. The action spectra for advance and delay phase shifts are similar; the most effective wavelengths are in the blue region, with a sharp cutoff above 500 nanometers. This similarity suggests that the same photoreceptive pigment mediates both advance and delay phase shifts.
