Amblyomma mixtum is a tick species in the Amblyomma cajennense complex. The known geographic range of A. mixtum extends from Texas in the USA to western Ecuador and some islands in the Caribbean. Amblyomma mixtum is a vector of disease agents of veterinary and public health importance. The objective of this study was to describe the life cycle of A. mixtum under laboratory conditions. Bovines, rabbits and sheep were infested with larvae, nymphs, and adult ticks under controlled conditions to assess several biological parameters. Eggs, larvae, nymphs and adults were kept in an incubator (27 °C temperature and 80% relative humidity) when they were off the host. The average life cycle of A. mixtum was 88 and 79 days when fed on rabbits and cattle, respectively. Sheep were found to be unsuitable because no ticks attached. The rabbit is a more practical host to maintain a colony of A. mixtum under laboratory conditions. The data from this study can be considered as an example for the life cycle of A. mixtum. However, caution must be exercised when making comparisons to the biology of A. mixtum in its natural habitat.
混色花蜱是卡晏花蜱复合种中的一种蜱类。混色花蜱已知的地理分布范围从美国得克萨斯州延伸至厄瓜多尔西部及加勒比地区的一些岛屿。混色花蜱是对兽医和公共卫生具有重要意义的疾病病原体的传播媒介。本研究的目的是描述混色花蜱在实验室条件下的生命周期。在可控条件下，用幼虫、若虫和成年蜱感染牛、兔和羊，以评估若干生物学参数。卵（蛋）、幼虫、若虫和成虫在脱离宿主时置于培养箱中（温度27℃，相对湿度80%）。以兔和牛为宿主时，混色花蜱的平均生命周期分别为88天和79天。发现羊不适合，因为没有蜱附着。在实验室条件下，兔是维持混色花蜱种群更实用的宿主。本研究的数据可被视为混色花蜱生命周期的一个实例。然而，在与混色花蜱在其自然栖息地的生物学特性进行比较时必须谨慎。
