Daily rhythm of detachment of engorged larvae of Ixodes ricinus L. and Hyalomma anatolicum Koch is regulated by photoperiod. In photoperiodic conditions (16--20 hours of light p. d.) the maximum of detachment in H. anatolicum occurs at the beginning of photophase (the first 4--8 hours), but in I. ricinus it occurs at the second part of photo-phase (12--16 hours after the light is on). The rhythm of detachment is regulated according to the processes of endogenous circadian nature which are maintained in the continuous light and are species-specific. The phase entrainment of detachment in continuous light is also influenced by biorhythms of hosts.
蓖麻硬蜱和安纳托利亚璃眼蜱饱血幼虫的每日脱落节律受光周期调节。在光周期条件下（每天光照16 - 20小时），安纳托利亚璃眼蜱的最大脱落量出现在光照阶段开始时（最初4 - 8小时），但蓖麻硬蜱的最大脱落量出现在光照阶段的第二部分（开灯后12 - 16小时）。脱落节律是根据内源性昼夜节律过程调节的，这些过程在持续光照下得以维持且具有物种特异性。持续光照下脱落的相位调整也受宿主生物节律的影响。
