P. xylostella males exhibit better rhythm than females under 20 °C. (a) Locomotor activity rhythms of P. xylostella under 14L: 10D and 20 °C conditions. Double-plotted actograms show the locomotor activity patterns of the different days (left panel). Each row contains two consecutive days of locomotor activities (counts per 30 min), and the last day is repeated to ensure that the next day is always the beginning of the next row. The x-axis shows the time of day under LD conditions. Mean activity plots were used to show the activity patterns (middle panel). The blue dots on the plots are SEM. The gray shadings in the plots denote light-off conditions. Autocorrelation plots are used to determine the rhythm index (RI) (right panel). (b) Locomotor activity rhythms of the P. xylostella under the changing condition from 14L:10D to DD at 20 °C.
