The plant's development near the soil characterizes the sugar beet agrosystem. Soil pests are important in crop evolution, and less so the foliar ones. Research carried out at the Agricultural Research and Development Station Secuieni Neamț consisted of inventorying the species that attacked sugar beet plants from the emergence period to the formation of the leaf rosette. The results showed that eight species attacked the sugar beet crop, belonging to the Coleoptera, Lepidoptera, and Homoptera orders. The highest densities of pests specific to sugar beet crops were recorded for the species Chaetocnema spp. (30 specimens), Bothynoderes punctiventris L. (26 specimens) and Opatrum sabulosum L. (18 specimens). In sugar beet crops, attacks by Agriotes larvae at seed germination were 30%, and during the vegetation period, the plants were attacked by B. punctiventris L. and Tanymecus spp. (30%), Chaetocnema spp. (15%), A. gamma L. (9%) and Aphis fabae (23%).
