The research was carried out in two commercial plantations located in Suceava and Neamț counties, using standard entomological sampling methods: chromotropic traps, pheromone traps, visual observations, and plant material sampling. Throughout the growing season, 12 harmful insect species were identified, the most common being Byturus tomentosus, Drosophila suzukii, Amphorophora agathonica, and Aphis idaei. A significant correlation was observed between climatic conditions (temperature and humidity) and the population dynamics of the pests, particularly during the months of May to July. Altitude and plantation exposure were also found to influence the structure of entomological communities and the level of infestation. The results contribute to a better understanding of current phytosanitary risks and can serve as a basis for the development of effective integrated pest management strategies, tailored to the ecological conditions of the mountainous area of the Eastern Carpathians.EnglishinsectsbiodiversityraspberrydynamicsArticle2069-8275
