1979-1980 年夏季，在美国科罗拉多州拉里默县对安德氏蜱虫的季节性活动进行了研究。 80 次使用了 25 个 CO2 平台捕集器。 80 米网格用于监控寻找主人的活动。 1979 年捕获的蜱虫被荧光涂料点标记，每个月使用不同的颜色。第二年夏天，11% 的标记蜱虫被重新捕获。使用林肯指数通过标记重捕法确定种群密度，1979 年 5 月的估计值为每公顷 1139 只蜱。在这两年中，蜱活动均于 3 月初开始，4 月底达到顶峰，到 6 月底几乎停止。在冬眠中存活至少 2 个冬天的蜱虫的实际科罗拉多蜱热感染率为 129/1000，这表明作为幼虫或若虫感染的蜱虫会长时间保留感染。
Studies of the seasonal activities of adult D. andersoni ticks were conducted in Larimer county, Colorado, USA, during the summers of 1979-1980. Twenty-five CO2 platform traps were used in an 80 .times. 80-m grid to monitor host-seeking activities. Ticks were marked with a spot of fluorescent paint as they were captured in 1979, with a different color used for each month. Eleven % of the marked ticks were recaptured the following summer. Using the Lincoln Index to determine population density by the mark-recapture method, an estimate of 1139 ticks/hectare was obtained for May 1979. In both years tick activity began in early March, peaked in late April, and virtually ceased by the end of June. The actual Colorado tick fever infection rate of painted ticks surviving at least 2 winters in hibernation was 129/1000, indicating that ticks infected as larvae or nymphs retain the infection for extended periods.
