TL;DR
Action spectra were determined for lightinduced phase shifts of the circadian rhythm of adult emergence in Drosophila pseudoobscura, suggesting that the same photoreceptive pigment mediates both advance and delay phase shifts.
Abstract
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.

The theory of entrainment outlined here gives an explicit basis for interpreting the action of night interruptions; and, among other things, indicates that the concept of "scotophil" needs more rigorous definition.

The expression of a circadian rhythm of conidiation by timex, a strain of Neurospora crassa, is inhibited by growth in continuous white light, and the action spectrum suggests that a carotenoid or flavin compound may be the photoreceptor, but does not allow one to determine conclusively whether the receptor is indeed a carOTenoid, flavin, or some other unrelated pigment.

An empirical relationship is found between temperature steps and pulses and, to first approximation, the +A+ or - A+ generated by 12 hr pulses may be computed from the A# generated by the steps comprising that pulse, justifying the assumption that the A+ normally effected by the step is accomplished rapidly (within a few hours).

Activity observed in the far red region of the spectrum beyond the absorption maximum of chlorophyll a suggests that an additional pigment, present in small amounts, may also act as sensitizer for photoinhibition.

A circadian rhythm of egg hatching in the moth Pectinophora gossypiella can be initiated with a brief light pulse, and the action spectrum for this effect has a peak in the blue and near ultraviolet region of the spectrum.
