Entrainability of the circadian rhythm of mosquito flight and locomotor activity was investigated by giving a 24-hr temperature cycle (28 degrees C for 16 hr, 23 degrees C for 8 hr) to the free-running rhythm or by shifting the temperature cycle. The phase angle difference between the entrained rhythm and the temperature cycle depended on the free-running period, but not on the circadian phase at which the temperature cycle started. The rhythm transients (advancing or delaying) to entrainment depended on phase, but did not depend on either the phase or the free-running period for their average speed. We postulate that flight and locomotor activity in the mosquito may be controlled by two circadian oscillators moving in different directions in response to the temperature cycle. It is likely that at least one of the oscillators is diphasic.
通过给自由运行节律施加24小时温度循环（16小时28摄氏度，8小时23摄氏度）或改变温度循环，研究了蚊子飞行和运动活动昼夜节律的可 entrainability。被 entrained 节律与温度循环之间的相位角差取决于自由运行周期，但不取决于温度循环开始时的昼夜相位。节律向 entrainment 的瞬变（提前或延迟）取决于相位，但其平均速度既不取决于相位也不取决于自由运行周期。我们推测，蚊子的飞行和运动活动可能由两个昼夜振荡器控制，这两个振荡器在响应温度循环时沿不同方向移动。很可能至少有一个振荡器是双相的。 （注：“entrainability”等词可能是专业术语，这里直接保留英文未翻译，因为不太明确其准确的中文术语，具体翻译可根据相关医学专业知识进一步调整。）
