The climate change in the last decades have brought increased average annual temperatures all over the world. The north-eastern region of Transylvania is no exception to this trend. Under the influence of this phenomenon and of the way in which average daily temperatures are distributed across the year, we observed certain changes in the flight dynamic of the adult males of the codling moth Cydia pomonella (L.). The preliminary data collected by the use of pheromone traps (Atrapom), along the vegetative period of 2019, regarding the flight of the moths, showed an extended flight span with two to five weeks than the flight recorded in the same orchards between 2004 and 2006. There is also a significant increase of the number of moths caught in the pheromone traps in 2019 when compared to the number of moths caught between 2004 and 2006. In the next years the monitoring of the flight dynamic of Cydia pomonella (L.) will continue in order to confirm that the rising average temperatures lead to an environment that favour certain pests.
