Bed bug aggregation pheromone

The **bed bug aggregation pheromone** is a chemical blend produced by adult and juvenile bed bugs (*Cimex lectularius*) to signal the presence of a safe shelter and promote aggregation behavior[1][5][7]. The canonical composition includes five volatile components—**dimethyl disulfide**, **dimethyl trisulfide**, **(E)-2-hexenal**, **(E)-2-octenal**, and **2-hexanone**—which attract bed bugs, as well as one less-volatile component, **histamine**, which causes arrested movement and encourages bed bugs to remain in the area[1][2][5][7][9]. Synthetic aggregation pheromone blends have been developed to mimic these cues, primarily for pest surveillance, detection, and control via trapping[1][2][5][7][10]. These synthetic blends are not biological targets in the classical pharmacological sense (e.g., not a receptor, ion channel, or enzyme), but rather function as behavioral lures or environmental modulators. The identification and use of this pheromone blend have improved bed bug detection and may aid in population control strategies, though it is not a therapeutic drug target[2][5][8]. There is no recognized abbreviation for this blend, and it is best referenced by its full chemical or behavioral description. No therapies, drugs, diagnostic biomarkers, or safety profiles are directly associated with this semiochemical blend beyond its application in insect control measures[1][5][10].
