Field trials were conducted during 2016 in order to investigate the efficacy of clothianidin (500 g a.i./kg in WP formulation) in control of pear psylla (Cacopsylla pyri L.) at two localities: Radmilovac and Begaljica near Belgrade, Serbia. Experiments have been conducted in accordance with standard EPPO method. Results of the field trials indicate good efficacy of clothianidin in pear psylla control on pear. The efficacy of clothianidin preparation at 0.035% concentration at the locality of Radmilovac was good (92.9-97.9%). Same preparation at 0.026% concentration had a significantly lower level of efficacy (82.27- 85.71%), and had the lowest efficacy at 0.017% concentration (53.5-57.5%). The efficacy of clothianidin preparation, at the locality of Begaljica at 0.035% concentration was also good (92-98.4%), while significantly lower efficacy (81.5-83.4%) was determined at 0.026% concentration. Very poor efficacy (56.3-58%) was achieved at the lowest concentration (0.017%).
