在实验室条件下[（27 +/- 1 ℃），70% RH，6 L：18 D]，森林革蜱Olenev的最小生命周期平均持续时间为87.5天（范围74-102天）。卵的孵化期为15.3天，幼虫和蛹的取食前、取食和蜕皮前的平均时间分别为5.5、4.0和7.3天和5.2、5.0和14.6天;雌成虫取食前期、取食期、产卵前期和产卵期分别为7.8d、4.5d、4.3d和14.0d。雌虫饱腹体重与产卵量呈极显著正相关（r=0.9877，p < 0.001）。雌性的生殖效率指数（REI）和生殖适合度指数（RFI）分别为11.09和9.58。未观察到若虫饱腹体重与结果性别之间的关系。雌虫存在延迟取食和不产卵现象（6月和7月），低温（-10 ℃）处理45 d可解除产卵滞育。但滞育后雌虫产下的卵块显著小于3、4、5月饱食雌虫产下的卵块。
The minimum life cycle of Dermacentor silvarum Olenev had a mean duration of 87.5 days (range 74-102 days) under laboratory conditions [(27 +/- 1 degrees C), 70% RH, 6 L: 18 D]. The mean time in (days) for the different stages of its cycle was as follows: incubation period of eggs was 15.3 days; prefeeding, feeding and premoulting periods of larvae and nymphs averaged 5.5, 4.0 and 7.3 days, and 5.2, 5.0 and 14.6 days, respectively; prefeeding, feeding, preoviposition and oviposition periods of female adults lasted for 7.8, 4.5, 4.3 and 14.0 days, respectively. There existed a highly significant correlation between engorged body weight of females and egg masses laid (r=0.9877, p < 0.001). The reproductive efficiency index (REI) and reproductive fitness index (RFI) in females were 11.09 and 9.58, respectively. No relationship between nymphal engorged body weight and resultant sexes was observed. Delayed feeding and non-oviposition (in June and July) existed in females, and low temperature (-10 degrees C) treatment for 45 days could terminate oviposition diapause. However, the egg masses laid by post-diapause females were significantly smaller than those laid by females engorged in March, April and May.
