This paper deals with the results of field trials of domestically produced pheromone preparations for a dangerous quarantine pest - the brown marmorated stink bug, Halyomorpha halys Stal, 1858 (Hemiptera: Pentatomidae). In 2017, the domestically produced pheromone preparations for H. halys were first synthesized. In 2018, large-scale field trials of pheromone preparations for H. halys were conducted in the quarantine phytosanitary zone in Sochi (Southern Russia) and the Republic of Abkhazia. According to the study results, the highest attractiveness both for adult insects (imago) and nymphs of H. halys was demonstrated by the preparation consisting of (3S,6S, 7R, 10S)-10,11-epoxy-1-bisabolen-3-ol, (3R,6S, 7R, 10S)-10,11 -epoxy-1-bisabolen-3-ol, and methyl-(E, E, Z)-2,4,6-decatrienoate. This preparation is recommended for the use in pyramidal pheromone traps for pest monitoring at a dose of 4 mg/dispenser, and for mass pest trapping at a dose of 12 mg/dispenser.
