A review of the literature on the circadian activity rhythms in cockroaches led Vancassel (1968) to suggest that both the eyes and the ocelli play a role in the induction of rhythms in previously arrhythmic cockroaches. Experiments involving eye‐opaquing or cauterizing techniques were performed to test this hypothesis. The results imply that both kinds of photoreceptors are involved in the setting up of a rhythm, and that light transmitted via the peri‐antennal cuticle may be as well. The role of these forms of photoreception in the entrainment of free‐running circadian rhythms was not examined.
