随着土壤深度的增加，日温幅值逐渐减小，温度循环的相位延迟。葱蝇Delia antiqua（Meigen）（双翅目：花蝇科）在2-20 cm土层中化蛹，其羽化期随温度的降低而提前。这种“温度振幅响应”被认为允许位于任何深度的蛹在清晨羽化。本文研究了D.振幅在1 ° C和20 °C之间的反方形温周期。脓疱暴露的温度周期是方波温度周期，通常用于实验室实验，或伪正弦温度周期，更接近自然日温度周期，平均温度为25或20 °C。由方波周期中的突然温度升高引起的羽化爆发在伪正弦温度周期中显然受到抑制。羽化时间显示出一个明确的定量位移由5.9-8.6小时，在响应温度振幅，无论平均温度和温度周期的形状。羽化时间的变化在1 ° C和8 °C的幅度之间是明显的，但是在8 °C或更高的幅度之间是小的。迪利亚antibolamay可以进化以补偿在实际土壤环境中的温度幅度的可能范围内的温度变化的深度相关的相位延迟。
With increasing soil depth, the diel temperature amplitude gradually decreases and the phase of the temperature cycle is delayed. The onion flyDelia antiqua(Meigen) (Diptera: Anthomyiidae), which pupates at a soil depth of 2–20 cm, advances the eclosion phase of its circadian rhythm as the temperature amplitude decreases. This ‘temperature amplitude response’ is considered to allow pupae located at any depth to eclose in the early morning. The present study examines the temperature amplitude response ofD. antiquaunder thermoperiods with amplitudes ranging between 1 and 20 °C. The thermoperiod to which pupae are exposed is either a square‐wave temperature cycle, which is generally used for laboratory experiments, or a pseudo‐sinusoidal temperature cycle, which more closely resembles natural daily temperature cycle, at an average temperature of either 25 or 20 °C. Bursts of eclosion invoked by the abrupt temperature increase in square‐wave cycles are apparently repressed in pseudo‐sinusoidal temperature cycles. Eclosion time shows a clear quantitative shift by 5.9–8.6 h in response to temperature amplitude regardless of the average temperature and the shape of the temperature cycle. The change in the eclosion time is clearly noticeable between amplitudes of 1 and 8 °C but is small between amplitudes of 8 °C or more.Delia antiquamay evolve to compensate for the depth‐dependent phase delay of temperature changes within the possible range of temperature amplitudes in actual soil environments.
