One generation of Amblyomma coelebs life cycle under experimental conditions was evaluated. Ten tick pairs were allowed to feed on rabbits under laboratory conditions (LC), resulting six engorged females with a mean weight of 1,403.9 mg. Two females were maintained in a forest reserve under natural conditions (NC), and four were maintained in incubators (LC). The engorgement period lasted 10.33 days. Pre-oviposition periods were 10.75 (NC) and 22 days (LC). The mean egg-mass weight was 514.76 mg, and the blood meal conversion index was 36.67% (LC). Incubation period under NC and LC were 91 and 56.33 days and hatching rates were 50% and 28.33%, respectively. Larval engorgement period ranged from 4 to 10 days, with average weight of 1.1 mg. Engorged larvae were incubated under NC and LC, with a premolt period of 27 to 36 days and molting rate of 7.1% and 28.7%, respectively. Nymphal engorgement period ranged from 5 to 7 days, with a mean weight of 18.8 mg and a recovery rate of 54.54%. In LC, the ecdysis mean period was 24.5 days, and molting rate was 44.44%, resulting in 24 adult A. coelebs. Our results show a life cycle of 187.45 (NC) and 149 (LC) days.
在实验条件下评估了一代草原花蜱的生命周期。在实验室条件下（LC）让十对蜱虫叮咬兔子，得到六只饱血雌蜱，平均体重为1403.9毫克。两只雌蜱置于自然条件下（NC）的森林保护区，四只置于培养箱中（LC）。饱血期持续10.33天。产卵前期分别为10.75天（NC）和22天（LC）。平均卵块重量为514.76毫克，血餐转化率为36.67%（LC）。在NC和LC条件下的孵化期分别为91天和56.33天，孵化率分别为50%和28.33%。幼虫饱血期为4至10天，平均体重为1.1毫克。饱血幼虫在NC和LC条件下孵化，若虫前期为27至36天，蜕皮率分别为7.1%和28.7%。若虫饱血期为5至7天，平均体重为18.8毫克，回收率为54.54%。在LC条件下，蜕皮平均期为24.5天，蜕皮率为44.44%，得到24只成年草原花蜱。我们的结果显示生命周期在NC条件下为187.45天，在LC条件下为149天。
