Gene silencing by period (per) and cycle (cyc) double-stranded RNA (dsRNA) injection in Riptortus pedestris. Northern blotting for per (left) and cyc (right) was performed using total RNA from the whole bodies of females at Zeitgeber time (ZT) 8 on day 5 (a), or on day 20 (b). Northern blotting for per was also performed using total RNA from the heads of cyc RNA interference (RNAi) females at ZT8 on day 5 (c). Ribosomal RNAs (rRNAs) are shown as references.
