Circadian rhythm of sperm movement in the male reproductive tract of the gypsy moth, Lymantria dispar

Several days before adult eclosion sperm starts being released from the testis of the gypsy moth in a daily rhythmic fashion. This rhythm has circadian endogenous nature since it free-runs in constant darkness, undergoes rapid phase-shifts and is temperature compensated. The rhythm can be initiated,...

More Information
Summary:Several days before adult eclosion sperm starts being released from the testis of the gypsy moth in a daily rhythmic fashion. This rhythm has circadian endogenous nature since it free-runs in constant darkness, undergoes rapid phase-shifts and is temperature compensated. The rhythm can be initiated, entrained by the photoperiod and free-run in isolated pupal abdomens. Two rhythmic events, the release of sperm from the testis and its transfer to seminal vesicles, are independently modulated by temperature and photoperiod.
