The possibility of controlling of Synanthedon myopaeformis Bkh. by mass‐trapping operations was investigated in Northern Italy from 1986 to 1991. In the experiments the effectiveness of 6 kinds of traps (3 sticky traps and 3 funnel traps), four doses of pheromone, the catching power of the traps changing their position on the trees, the interactions between pheromone traps placed along or across the mean wind direction and those between a central trap surrounded by four traps in a circle was considered. According to the results obtained during these preliminary experiments, and using an empirical method in 1990 and 1991, the effectiveness of controlling of 3 different trap densities per ha was considered: 6 traps/ha, 12 traps/ha, and 24 traps/ha. The results obtained with the empirical method suggest the possibility of operating with suitable performance in the trapping of 5. myopaeformis with 12 traps per ha. Comparing these values with those obtained in the preliminary tests reveal that the differences are small. Zusammenfassung Über die Möglichkeit des Massenfangs von Synanthedon myopaeformis Bkh. (Lep., Sesiidae ) Es wurde die Möglichkeit der Bekämpfung von S. myopaeformis mittels Massenfangs in Pheromonfallen 1986–1991 in Norditalien untersucht. Dabei wurden ermittelt: die Wirksamkeit von 6 Arten von Fallen (3 Leim‐ und 3 Trichterfallen‐Typen), 4 Dosen des Pheromons, die Fangkraft der Fallen in Abhängigkeit von ihrer Lage am Baum, der Windrichtung sowie ihrer Zahl und Anordnung im Bestand. Von 3 getesteten Fallendichten (6, 12 und 24 Fallen/ha) erbrachten 12 Fallen/ha die besten Ergebnisse, die den Pheromonfang als geeignetes Bekämpfungsmittel gegen S. myopaeformis erscheinen lassen.
