Host-targeted technologies provide an alternative to the use of conventional pesticide applications to reduce the abundance of Ixodes scapularis Say, the vector for an array of tick-associated human diseases. We compared the ability of Damminx Tick Tubes (Damminix) and SELECT Tick Control System (Select TCS) bait boxes to control host-seeking I. scapularis nymphs in a wooded residential environment. Small mammals accepted and used Select TCS bait boxes with greater frequency compared to Damminix tubes over the course of the 2-yr trial. Nymphal tick infestation prevalence and intensity on captured mice and chipmunks provided no conclusive evidence of a treatment effect during May-June of both years. However, both treatments had a measurable effect on larval tick burdens in July-August and the magnitude of the effect was greater at the Select TCS-treated area and reflected the fact that Select TCS effectively treated chipmunks, while Damminix did not. Deployment of Damminix resulted in 27.6 and 20.3% control of questing nymphs in treated areas at 1 yr and 2 yr postintervention, while Select TCS bait boxes provided 84.0 and 79.1% control, respectively. The economics of residential tick control using these products in wooded residential landscapes is discussed.
宿主靶向技术为减少传播多种蜱相关人类疾病的伊蚊数量提供了替代传统农药应用的方法。我们比较了 Damminx 蜱管（Damminix）和 SELECT 蜱控制系统（Select TCS）诱捕盒在林地居住环境中控制宿主寻找的 I. scapularis 若虫的能力。在 2 年的试验过程中，与 Damminix 管相比，小型哺乳动物更频繁地接受和使用 Select TCS 诱饵盒。在 5 月至 6 月期间，捕获的老鼠和花栗鼠上的蜱幼虫感染率和强度并没有确凿的证据表明治疗有效。然而，两种处理方法都对 7 月至 8 月的幼虫蜱虫负担产生了可衡量的影响，在 Select TCS 处理区域的影响更大，这反映了 Select TCS 有效治疗了花栗鼠，而 Damminix 则没有。在干预后 1 年和 2 年，Damminix 的部署使处理区域中觅食的若虫分别控制了 27.6%和 20.3%，而 Select TCS 诱捕盒分别控制了 84.0%和 79.1%。讨论了在树木繁茂的居住环境中使用这些产品进行住宅蜱控制的经济性。
