Burrows of the gopher tortoise, Gopherus polyphemus Daudin, were sampled for Ornithodoros turicata (Dugès) infestation using carbon dioxide baits and vacuum extraction. Ticks were captured, marked, released, and recaptured, and population estimates were made using the Lincoln index. Estimated population ranged from 47 to 1,338 ticks per burrow. The tick population consisted predominantly of nymphs, with a significant increase in the larval population during the months of June and July. Adult sex ratio was slightly male-biased, but numbers of adults collected were consistently low. Ticks exhibited a low interburrow movement, but depth preferences fluctuated with season; more ticks occurred in the upper strata of the burrows during the hot, humid months.
使用二氧化碳诱饵和真空抽取法，对沙龟（Gopherus polyphemus Daudin）的洞穴进行采样，以检测感染土拉钝缘蜱（Ornithodoros turicata (Dugès)）的情况。蜱虫被捕获、标记、释放并重新捕获，然后使用林肯指数进行种群估计。每个洞穴的蜱虫估计数量在47至1338只之间。蜱虫种群主要由若虫组成，在6月和7月幼虫数量显著增加。成年蜱虫的性别比例略偏向雄性，但捕获的成年蜱虫数量一直较少。蜱虫在洞穴间的移动较少，但深度偏好随季节波动；在炎热潮湿的月份，洞穴上层出现的蜱虫更多。
