Z-scored flight activity shows multiple time differences between An. farauti and An. hinesorum mosquitoes at the onset of night and during other parts of the scotophase. a Flight activity of An. farauti (blue) and An. hinesorum (red) over 24 h under normal LD conditions. Values are mean of Z-scored activity. Day and night are indicated by horizontal white/black bars. b Dusk and early night-related flight activity. Values are mean ± SEM of Z-scored activity between ZT11 and ZT13 under normal LD cycle conditions. Time shown in Zeitgeber time (ZT) decimal format. Dusk progression shown by horizontal white/black bar. Student’s t-tests were performed, +P < 0.05, *P < 0.01
