Effective bed bug (Cimex lectularius L.) monitors have been actively sought in the past few years to help detect bed bugs and measure the effectiveness of treatments. Most of the available active monitors are either expensive or ineffective. We designed a simple and affordable active bed bug monitor that uses sugar-yeast fermentation and an experimental chemical lure to detect bed bugs. The sugar-yeast mixture released carbon dioxide at a similar rate (average 405.1 ml/min) as dry ice (average 397.0 ml/min) during the first 8 h after activation. In naturally infested apartments, the sugar-yeast monitor containing an experimental chemical lure (nonanal, L-lactic acid, 1-octen-3-ol, and spearmint oil) was equally effective as the dry ice monitor containing the same lure in trapping bed bugs. Placing one sugar-yeast monitor per apartment for 1-d was equally effective as 11-d placement of 6-18 Climbup insect interceptors (a commonly used bed bug monitor) under furniture legs for trapping bed bugs. When carbon dioxide was present, pair-wise comparisons showed the experimental lure increased trap catch by 7.2 times. This sugar-yeast monitor with a chemical lure is an affordable and effective tool for monitoring bed bugs. This monitor is especially useful for monitoring bed bugs where a human host is not present.
在过去几年中，人们一直在积极寻找有效的臭虫（温带臭虫）监测器，以帮助检测臭虫并评估防治效果。现有的大多数主动式监测器要么价格昂贵，要么效果不佳。我们设计了一种简单且经济实惠的主动式臭虫监测器，它利用糖 - 酵母发酵和一种实验性化学引诱剂来检测臭虫。在激活后的前8小时内，糖 - 酵母混合物释放二氧化碳的速率（平均405.1毫升/分钟）与干冰（平均397.0毫升/分钟）相似。在自然滋生臭虫的公寓中，含有实验性化学引诱剂（壬醛、L - 乳酸、1 - 辛烯 - 3 - 醇和留兰香油）的糖 - 酵母监测器在捕获臭虫方面与含有相同引诱剂的干冰监测器效果相当。在每个公寓放置一个糖 - 酵母监测器1天，与在家具腿下放置6 - 18个Climbup昆虫拦截器（一种常用的臭虫监测器）11天在捕获臭虫方面效果相同。当存在二氧化碳时，两两比较显示实验性引诱剂使诱捕量增加了7.2倍。这种带有化学引诱剂的糖 - 酵母监测器是一种经济实惠且有效的臭虫监测工具。该监测器对于在没有人类宿主的地方监测臭虫特别有用。
