Fig. 2

Daily activity profile of R. robustus II and R. prolixus under 12:12 LD. Average locomotor activity of R. robustus II (blue lines, N = 30) and R. prolixus (green lines, N = 65), depicted by average values of five days of recording. The horizontal white bar represents the light phase and the black bar indicates the dark phase. ZT = Zeitgeber Time within a light/dark cycle experiment. ZT 0 corresponds to the lights-on event and ZT 12 to the lights-off event
