During 2018 and 2019 in the IPM apple orchard Obreska (County of Zagreb) suppression terms of the codling moth were investigated. Pheromone traps were placed on three locations (T 1/6, T 3/3 and T 4/3) to monitor the flight of pest in the orchard. The suppresion terms of codling moth were determined bassed on the degree days. The results of the research showed that the pest on some locations (T 3/3 and T 4/3) developed in critical populations that could cause economic damage in the production of apples and should be suppressed. During the years 2018 and 2019, the pest had to be suppressed on average once or twice during the growing season, which was done in practice. In the orchard Obreska, the pest control is based on the principles of integrated protection, which gives the producer multiple economic and environmental benefits. Less insecticides are used in production, which ultimately affects production quality, human health and the environment.
