THE EFFECTIVENESS OF PHEROMONES OF BROWN MARMORATED STINK BUG HALYOMORPHA HALYS (STåL, 1855) AND TRAPS OF VARIOUS CONSTRUCTIONS IN SATSUMA MANDARIN AGROCENOSES IN ABKHAZIA

The brown marmorated stink bug Halyomorpha halys (Stål, 1855) is a dangerous invasive pest of agricultural plants on the Black Sea coast of the Caucasus. The research was carried in a mandarin orchard, in Sukhum region of the Republic of Abkhazia, in 2020. Pheromone traps were hung on June 15 and removed on October 13. Two options were studied: cylindrical Italian traps and aggregation pheromone produced by the Plant Quarantine Centre (Russia); adhesive plates and the aggregating pheromone PHEROCON® manufactured by Trécé Inc (USA). Both Russian and American pheromones have been shown to be effective in attracting brown marmorated sting bugs. In total, during the observation season, 1 720 individuals were caught on the adhesive plates, and 1 923 individuals were caught in the cylindrical traps, which is 11.8 % more. The adhesive plates turned out to be more effective in trapping the initial stages of the pest's life cycle (nymphs of II and III instars). Up to 154 specimens were caught on the adhesive plates, and up to 102 brown marmorated sting bugs per week were caught in the cylindrical trap. It was found that the efficiency of the adhesive plates is higher at the initial stage of the pest colonization on mandarin plantations, and cylindrical traps were more effective- in the autumn period (the period of fruit ripening).
