The preoviposition period of the tick Rhipicephalus evertsi Neumann maintained under laboratory conditions at 26 C was 6.1 +/- 0.38 days. The average number of eggs produced during the oviposition period was 10,400 +/- 397 (max. 13.307, min. 7,558). The greatest daily egg production was recorded on the 3rd day (1.107 eggs/female). The incubation period of eggs at 26 C was 24.8 +/- 1.37 and the feeding time of the larvae and nymphs (a two-host tick) was 17.2 +/- 0.14 days at 26 C. This tick represents the two-host type of cycle and the percentage of larvae, pharate nymphs, and nymphs on the host at various intervals after attachment was recorded. The changes in the weight of the immature stages during the feeding period was examined daily. Nymphs which produce males were lighter in weight (10.3 +/- 0.28 mg), than those which produce females (15.6 +/- 0.33) and males emerge (13.7 +/- 0.10 days of premolting period) before females (14.1 +/- 0.11 days).
在26摄氏度的实验室条件下饲养的埃氏扇头蜱（Rhipicephalus evertsi Neumann）的产卵前期为6.1±0.38天。产卵期平均产卵数为10400±397枚（最多13307枚，最少7558枚）。第3天的日产卵量最高（1107枚/雌蜱）。26摄氏度时卵的孵化期为24.8±1.37天，幼虫和若虫（二宿主蜱）在26摄氏度时的取食时间为17.2±0.14天。这种蜱代表二宿主型周期，并记录了附着后不同时间间隔在宿主上的幼虫、准若虫和若虫的百分比。每天检查取食期未成熟阶段的体重变化。产生雄蜱虫的若虫体重（10.3±0.28毫克）比产生雌蜱虫的若虫轻（15.6±0.33毫克），雄蜱虫在雌蜱虫之前出现（预蜕皮期13.7±0.10天）（雌蜱虫为（14.1±0.11天））。
