Fig. 4

Locomotor activity/rest behavior of R. robustus II and R. prolixus under 12:12 LD followed by constant darkness (DD). Double-plotted actograms for R. robustus II (a; N = 23) and R. prolixus (b; N = 50) depicting five consecutive days under 12:12 LD followed by 23 days under constant darkness and reverting to another five days under 12:12 LD. c Smoothed double-plotted actograms of both species under constant darkness. The shaded dark grey areas indicate dark phase and light grey areas indicate the subjective days in constant darkness. d Acrophase of R. robustus II (red dotted lines) and R. prolixus (black dotted lines) during the 33 days of experiment. Dashed lines represent the transition from LD to DD (top) and from DD to LD (bottom). e-g Free running period length of R. robustus II (circles) and R. prolixus (squares), based on the whole 23-day period under DD (e), the first 10 days (f) and the last 13 days (g). Solid lines represent the average ± SEM. Dotted lines mark the 24-h period length
