抽象的。采采蝇成虫羽化的时间，通常发生在下午三点左右，是由温度升高的每日周期调节的。如果维持一个温度循环，羽化的节奏在连续的光照或连续的黑暗下持续存在。人为地将温度峰值转移到暗相会导致羽化模式随之发生变化。每日温度变化小到0.4°C就足以建立这种节律。羽化活动跟踪温度峰值，即使脉冲持续时间短（4小时）或具有12或36小时的不规则频率。温度诱导的节律提供了一种简单的机制来区分雌性和雄性。在同一天化蛹的个体在25°C下在4-5天的时间内与成虫蜕皮，并且在这样的集合中，雌性是第一个蜕皮的。这种区别使得可以主要收集一种性别的样本，这一特征可能有助于收集雄性用于雄性不育技术。
Abstract. The timing of adult eclosion in tsetse, an event that normally occurs in mid‐afternoon, is regulated by the daily cycle of temperature elevation. If a temperature cycle is maintained, the rhythm of eclosion persists under continuous light or continuous darkness. Artificially shifting the temperature peak to the scotophase results in a concomitant shift in the eclosion pattern. Daily temperature variations as small as 0.4°C are sufficient to establish the rhythm. Eclosion activity tracks the temperature peak, even if the pulses are of short duration (4 h) or with irregular frequencies of 12 or 36 h. The temperature‐induced rhythm offers a simple mechanism for separating females and males. Individuals that pupariate on the same day eclose as adults over a 4–5 day period at 25°C, and in such collections, females are the first to eclose. This distinction makes it possible to collect samples of predominately one sex, a feature that may facilitate the collecting of males for use in the sterile‐male technique.
