Abstract: The effectiveness of pheromone lures for Grapholita molesta (Busck 1916) from Propher (Czech Republic) and Pherobank (Netherlands), the attractiveness of green and transparent pheromone traps and the representation of non-target species were evaluated in three study areas of southern Moravia (Czech Republic) in 2019-2021 (24 traps per year). A total of 6 536 Grapholita molesta and 946 individuals of 17 non-target species were collected. Grapholita molesta was frequently captured in green delta traps with a Pherobank pheromone lure. Therefore, pheromone lures from different manufacturers have different efficacy and require the independent setting of harmfulness thresholds. An overview of non-target species recorded by other authors was compiled. Among the non-target species, morphologically similar species of Tortricidae dominated, causing considerable problems in the signalling of control measures of the target species.
