Bed bugs, Cimex lectularius L., are now considered a serious urban pest in the United States. Because they are small and difficult to find, there has been strong interest in developing and using monitoring tools to detect bed bugs and evaluate the results of bed bug control efforts. Several bed bug monitoring devices were developed recently, but their effectiveness is unknown. We comparatively evaluated three active monitors that contain attractants: CDC3000, NightWatch, and a home-made dry ice trap. The Climbup Insect Interceptor, a passive monitor (without attractants), was used for estimating the bed bug numbers before and after placing active monitors. The results of the Interceptors also were compared with the results of the active monitors. In occupied apartments, the relative effectiveness of the active monitors was: dry ice trap > CDC3000 > NightWatch. In lightly infested apartments, the Interceptor (operated for 7 d) trapped similar number of bed bugs as the dry ice trap (operated for 1 d) and trapped more bed bugs than CDC3000 and NightWatch (operated for 1 d). The Interceptor was also more effective than visual inspections in detecting the presence of small numbers of bed bugs. CDC3000 and the dry ice trap operated for 1 d were equally as effective as the visual inspections for detecting very low level of infestations, whereas 1-d deployment of NightWatch detected significantly lower number of infestations compared with visual inspections. NightWatch was designed to be able to operate for several consecutive nights. When operated for four nights, NightWatch trapped similar number of bed bugs as the Interceptors operated for 10 d after deployment of NightWatch. We conclude these monitors are effective tools in detecting early bed bug infestations and evaluating the results of bed bug control programs.
臭虫，Cimex lectularius L.，现在被认为是美国严重的城市害虫。由于它们体积小且难以发现，因此人们强烈希望开发和使用监测工具来检测臭虫并评估臭虫防治工作的结果。最近开发了几种臭虫监测设备，但它们的效果尚不清楚。我们比较评估了三种含有引诱剂的主动监测器：CDC3000、NightWatch 和自制干冰陷阱。被动监测器（不含引诱剂）Climbup Insect Interceptor 用于在放置主动监测器前后估计臭虫数量。还将拦截器的结果与主动监测器的结果进行了比较。在有人居住的公寓中，主动监测器的相对有效性为：干冰陷阱>CDC3000>NightWatch。在轻度感染的公寓中，拦截器（运行 7 天）捕获的臭虫数量与干冰陷阱（运行 1 天）相同，捕获的臭虫数量多于 CDC3000 和 NightWatch（运行 1 天）。与目视检查相比，拦截器在检测少量臭虫方面也更有效。CDC3000 和干冰陷阱运行 1 天与目视检查在检测极低水平的感染方面同样有效，而 NightWatch 运行 1 天检测到的感染数量明显低于目视检查。NightWatch 的设计目的是能够连续运行几个晚上。当运行四个晚上时，NightWatch 捕获的臭虫数量与在部署 NightWatch 后运行 10 天的拦截器捕获的臭虫数量相同。我们得出结论，这些监测器是检测早期臭虫感染和评估臭虫防治计划结果的有效工具。
