Deer self-treatment devices ('4-posters') were evaluated for their efficacy in reducing populations of blacklegged ticks, Ixodes scapularis, and lone star ticks, Amblyomma americanum. At each of three locations in Maryland, 25 '4-posters' were operated in study areas of approximately 5.18 km2. Populations of host-seeking ticks were monitored by flagging of treated areas and similar untreated control areas without '4-posters.' From 1998 to 2002 the percent mortalities achieved were 69, 75.8 and 80 at the three study sites infested with I. scapularis nymphs, and 99.5 and 95.3 for A. americanum nymphs at the two sites where this species occurred.
对鹿用自我治疗装置(“四柱式”)减少黑脚蜱(肩突硬蜱)和孤星蜱(美洲钝眼蜱)数量的效果进行了评估。在马里兰州的三个地点,每个地点在约5.18平方公里的研究区域内设置了25个“四柱式”装置。通过在有处理装置的区域以及没有“四柱式”装置的类似未处理对照区域进行拖旗法来监测宿主寻找蜱的数量。1998年至2002年期间,在三个有肩突硬蜱若虫出没的研究地点,实现的死亡率分别为69%、75.8%和80%;在有美洲钝眼蜱若虫出现的两个地点,该物种若虫的死亡率分别为99.5%和95.3%。
