In the period 2001-2004, experiments were conducted in the region of Backa (northern Serbia) to assess the efficiency of insecticide treatment of sugar beet seeds in controlling soil pests (larvae of Elateridae family) and reducing the damage caused by beet weevil (Bothynoderes punctiventris Germ.) and flea beetle (Chaetocnema tibialis Illig.). Several insecticides, mostly systemic ones (carbofuran, thiamethoxam, fipronil, imidacloprid and clothianidin), and their combinations with pyrethroids in different doses were tested in field conditions. Stand density, percentages of plants damaged by Bothynoderes punctiventris and Chaetocnema tibialis, injury level and weight of juvenile plants served as parameters for evaluation of insecticide efficiency. Most of the insecticides applied to seeds provided a significantly better stand density compared with the untreated control. Because of their systemic action, imidacloprid, thiamethoxam and their mixtures with pyrethroids provided very good protection of juvenile plants from Chaetocnema tibialis and in some cases from Bothynoderes punctiventris.
