The research was carried out within SCDP Iaşi, in two lots with a different crop technology. The observations concerned the entire entomofauna of arthropods from a walnut orchard where a conventional cultivation technology was applied and in a walnut orchard where ecological methods of protection against diseases and pests were applied. The research was carried out during 2018-2019, when the method of soil traps Barber type was used, while the flight curve of the pest Cydia pomonella was followed with help of synthetic pheromones traps, AtraPom type. The observations were made throughout the vegetation period, from May to September, having as research material 4 walnut genotypes, in the seventh year after planting, being grafted on Juglans regia. In the case of the conventional variant, phytosanitary treatments with fungicides and insecticides were performed, and in the ecological walnut variant, no phytosanitary treatments were performed, pest control being performed using biotechnical means, using only traps with synthetic sex pheromones AtraPom. During this period, climatic factors were also analyzed, which influence the biology of useful and harmful species. Following the monitoring and determination of all species collected, data were recorded on the abundance and dynamics of existing fauna.
