The recent decades' resurgence of bed bugs as a public health concern in industrialized countries has driven an increased interest on new sustainable insecticide-free methods to monitor and control these ectoparasites. Current methods of detection rely mainly on visual inspection or canine scent detection, which are methods that are time-consuming, require experience, are non-specific or require costly mission repetitions. Volatile organic compounds (VOCs) are considered an environmentally friendly alternative and a promising approach for bed bug detection. An overview of the released literature on VOCs, their chemical characteristics and their role in bed bugs' intra- and inter-species communications allowed us to highlight the identification of 49 VOCs in (23 molecules) and (26), which are emitted by both sexes during diverse compartments including aggregation (46), mating (11), defense (4), etc., and all life stages including exuviae or dead bed bugs as a principal indicator of infestation. The latter has a great importance for application of these semiochemicals in successful detection and control management of bed bugs and to prevent their further dispersion. This approach has the advantage of more reliability compared to conventional detection methods with no need for repeated inspections, household furniture moving or resident rehousing for bed bugs' VOC detection, which are commonly performed by active or passive sampling with absorbing tubes and analyzed by gas chromatography-based analytical platforms.
近几十年来，臭虫在工业化国家重新成为公共卫生关注的问题，这促使人们对新的可持续、无杀虫剂的监测和控制这些外寄生虫的方法产生了更大的兴趣。目前的检测方法主要依赖于视觉检查或犬类气味检测，这些方法既耗时，又需要经验，而且特异性差或需要昂贵的任务重复。挥发性有机化合物（VOCs）被认为是一种环保的替代品，也是臭虫检测的一种很有前途的方法。对已发表的关于 VOCs 的文献进行综述，包括它们的化学特性及其在臭虫种内和种间通讯中的作用，使我们能够突出识别出 49 种 VOCs，其中包括 （23 种分子）和 （26 种），这些 VOCs 由雌雄两性在不同的环境中释放，包括聚集（46）、交配（11）、防御（4）等，以及所有生命阶段，包括蜕皮或死亡的臭虫，作为虫害的主要指标。后者对于这些半化学物质在成功检测和控制臭虫以及防止其进一步扩散方面的应用非常重要。与传统的检测方法相比，这种方法具有更高的可靠性，无需进行重复检查、家庭家具移动或居民搬迁来检测臭虫的 VOC，这些方法通常是通过主动或被动采样用吸收管进行的，并通过基于气相色谱的分析平台进行分析。
