Double plotted actograms of locomotor activity of intact (A), DsRed2 RNAi (B), opUV RNAi (C), opB RNAi (D), and opLW RNAi crickets (E-G). Light cycles were advanced (A-F) or delayed (G) by 6Â h on the day indicated by an arrow head. White and black bars above actograms indicate light (white) and dark (black) phases. Shaded areas in actograms indicate dark phases. DsRed2 (B), opUV (C), and opB (D) RNAi crickets showed re-entrainment to the advanced LD in almost similar time course to that of intact cricket (A). opLW RNAi crickets showed a re-entrainment with longer transient cycles (E) or a free-running rhythm without re-entrainment (F and G). Note all of the crickets showed intense activity bouts at lights-on after phase advance (orange arrow, A-E) or enhanced activity peak in the light phase (blue arrow, F, G) when the subjective night was exposed to light.
