• The phase of locomotor activity of the onion fly, Delia antiqua, in LD12:12 advanced at a low temperature(20℃) as compared with that at a high temperature(25℃). The free-runningp eriod(τ) in constant darkness (DD) at 20℃ became shorter than that at 25℃, suggesting that the phase advance of locomotor activity in LD cycles at 20℃ was caused by the decrease in τ. In constant light(LL), the locomotor activity was arrhythmic at a constant temperature. In both DD and LL, the locomotor activity was entrained to a 12 hr 25℃:12hr 20℃ temperature cycle; the activity occurred in the thermophase and its peak delayed with age. However, the delay in LL was smaller than that in DD. At a cycle of 12hr cool(20℃) light and 12hr warm(25℃) dark, the fly showed a similar activity pattern to that in LD 12:12 at a constant temperature (20℃ or 25℃); the activity occurred in the light phase. This suggests that LD cycle is a stronger zeitgeber than a temperature cycle to entrain the locomotor activity of D.antiqua.
