肉蝇（石蛉）有明显的光周期反应；它们在很长的时间里发育成成虫，而在很短的时间里，它们在蛹阶段就停止了发育。尽管在这个物种中，生物钟参与了光周期时间测量，但负责时间测量的生物钟神经元的解剖位置尚不清楚。我们在幼虫的大脑中检测到两个周期免疫反应细胞簇；一组位于背前区，另一组位于内侧区。我们进一步研究了它们的周期免疫反应性的时间变化，并比较了它们在不同光周期下的模式。
The flesh flySarcophaga similisshow a clear photoperiodic response; they develop into adults under long days, whereas they arrest their development at the pupal stage under short days. Although the involvement of a circadian clock in photoperiodic time measurement is suggested in this species, the anatomical location of the clock neurons responsible for the time measurement has been unknown. We detected two PERIOD-immunoreactive cell clusters in the larval brain; one cluster was located at the dorsoanterior region and the other at the medial region. We further investigated their temporal changes in PERIOD-immunoreactivity and compared their patterns under different photoperiods.
