), the ratio of activity phase to rest phase (α/ρ) and the total activity per cycle (TAPC) for males of the haH strain and the laH strain of D. helvetica entrained by natural LD 14.1:9.9 cycles in the naturally fluctuating temperature (NFT) regime and in constant temperature (CT) regime (20 ± 0.5°C) at the altitude of origin in the field.
