Bed bugs, (Cimex lectularius L.), are difficult to find because of their nocturnal and secretive behavior. In recent years, a number of monitors containing carbon dioxide (CO2), chemical lures, heat, or both, to attract bed bugs have been developed for detecting bed bugs. Ineffective trap design, lack of attraction of chemical lures, high cost of the CO2 delivery system, or insufficient CO release rates are some factors that limited the wide adoption of these monitors. To develop an affordable and effective monitor, we conducted a series of laboratory and field tests. Specifically, we tested a new pitfall trap design, a chemical lure mixture, different CO2 release rates, and a sugar and yeast mixture as CO2 source. Results show the new pitfall trap design was significantly more effective than Climbup insect interceptor, the most effective passive monitor available in the market for bed bugs. The experimental chemical lure mixture increased Climbup insect interceptor catch by 2.2 times. Results exhibit a distinct positive relationship between the CO2 release rates and bed bug trap catches. There were no significant differences between CO2 derived from cylinders and CO2 generated from sugar and yeast mixture in their attractiveness to bed bugs. The findings suggest an effective and affordable monitor can be made incorporating the new pitfall trap design, a sugar and yeast mixture, and a chemical lure.
臭虫（Cimex lectularius L.）因其夜间和隐秘的行为而难以发现。近年来，为了检测臭虫，已经开发出了许多含有二氧化碳（CO2）、化学引诱剂、热量或两者结合的监测器来吸引臭虫。监测器设计效果不佳、化学引诱剂缺乏吸引力、CO2 输送系统成本高或 CO2 释放率不足等因素限制了这些监测器的广泛应用。为了开发一种经济实惠且有效的监测器，我们进行了一系列实验室和现场测试。具体来说，我们测试了一种新的陷阱设计、一种化学引诱剂混合物、不同的 CO2 释放率以及糖和酵母混合物作为 CO2 源。结果表明，新的陷阱设计比市面上最有效的被动臭虫监测器 Climbup 昆虫诱捕器更有效。实验用的化学引诱剂混合物使 Climbup 昆虫诱捕器的捕获量增加了 2.2 倍。结果表明，CO2 释放率与臭虫诱捕器的捕获量之间存在明显的正相关关系。来自钢瓶的 CO2 和糖和酵母混合物产生的 CO2 对臭虫的吸引力没有显著差异。这些发现表明，一种有效的、经济实惠的监测器可以通过采用新的陷阱设计、糖和酵母混合物以及化学引诱剂来制造。
