Synanthedon myopaeformis (Borkhausen, 1789) (Lepidoptera: Sesiidae) is a prominent pest of commercial apple orchards in Europe. the sex pheromones of S. myopaeformis and food attractants based on apple juice, beer and red wine were evaluated as tools for monitoring and control the populations of S. myopaeformis in apple orchards in the Czech Republic. For monitoring S. myopaeformis flight activity, trap designs were also evaluated, and the results indicated that wing traps were more suitable than delta traps because of their high efficacy even at low population densities of S. myopaeformis. The flight activity patterns of S. myopaeformis showed high intrapopulation variability and variability between years. The use of pheromones as a mating disruption technique led to a decrease of tree injury in comparison to untreated controls during the three years of the experiment. The reduction of the number of S. myopaeformis larvae per tree on a 14-ha plot treated subjected to the mating disruption technique reached 56 % in the third year of the experiment. In the three-year experiment using food attractants for the mass trapping of S. myopaeformis, catches of S. myopaeformis in traps using a combination of beer and apple juice (50:50) at a density of 4 traps/ha on a 4-ha plot increased more than 4-fold.
