^aFlies were kept at indicated temperatures (18°C, 25°C, 29°C) and exposed to 4 days of 12∶12 LD followed by 7 days of DD.

^bTotal number of flies that survived until the end of the testing period.

^cPercentage of flies with activity rhythms having a power value of ≥10 and a width value of ≥2.

^dMeasure of the strength or amplitude of the rhythm.
