“…(E)-2-hexenal and (E)-2-octenal were reported to be essential components of bed bugs’ aggregation pheromones. The latter was confirmed in further investigations carried out by Gries et al [ 65 ], Dery et al [ 69 ] and Olson et al [ 70 ]. Additionally, the bed bugs’ feces were reported to contain a variety of compounds which serve as a component of their aggregation pheromones [ 71 ].…”

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 Cimex lectularius (23 molecules) and C. hemipterus (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.

“…Cimex adjunctus (Barber) (Hemiptera: Cimicidae) came from a single laboratory population and were kept in plastic jars and fed on rabbit blood (HemoStat) every 2 wk through an artificial feeding system (Gaire et al 2022). Cimex hemipterus F. (Hemiptera: Cimicidae) (Greenlane and Kuala Lampur strains) were reared in plastic jars and fed on defibrinated rabbit blood (HemoStat, Dixon, CA, USA) every 10 days through an artificial feeding system (Dery et al 2020). Rhodnius prolixus (Stål) (Hemiptera: Reduviidae) (single laboratory population established at NMSU) and Triatoma rubida (Hemiptera: Reduviidae) (Strain from Anthony, New Mexico) were reared in plastic containers and fed monthly on human blood (BioChemed Services, Winchester, VA, USA) containing the anticoagulant sodium citrate (BioChemed Services), through an artificial feeding system (Montes et al 2002).…”

Histamine is a biogenic amine that regulates multiple physiological functions in diverse organisms, specifically playing a central role in the mammalian immune response. The common bed bug, Cimex lectularius L. (Hemiptera: Cimicidae), excretes histamine in large amounts in its feces as a component of its aggregation pheromone, which contaminates homes. The potential health risks associated with the presence of indoor histamine are unclear, but to predict future exposure risks, it is critical that we understand if other arthropods excrete histamine in any discernible phylogenetic pattern. In the present study, we evaluated histamine excretion by various arthropods; specifically those commonly found in large numbers indoors, other hematophagous species, and other species in the order Hemiptera. To evaluate arthropods for histamine excretion, rearing containers for each arthropod were swabbed and/or the harborage substrates were collected. Samples were then analyzed for the presence of histamine using gas chromatography–mass spectrometry. For those arthropods where histamine was present above the method detection limit, total histamine excretion was quantified over a period of 2 wk. Our results indicate that histamine excretion is limited to hematophagous hemipterans (bed bugs, bat bugs, tropical bed bugs, and kissing bugs), suggesting that indoor histamine contamination in the United States can be primarily linked to bed bugs.
