| Tartalmi kivonat: | During the 1960s, the pear psyllid (Cacopsylla pyri) became the most significant pest of pear in many European countries. This pest is particularly problematic in intensive pear orchards due to its rapid development of resistance to insecticides and its production of large amounts of honeydew, which complicates control efforts. Changes in production technology and orchard structure led to the emergence of ecologically unstable agricultural systems that favored the development of R-selected organisms, including the pear psyllid. Attempts to control this pest using insecticides showed limited effectiveness, prompting research to focus on their application strategies. Therefore, a comprehensive strategy that involves novel insecticides and developing more effective control methods is necessary to reduce the impact of this pest on pear production. In this article susceptibility of C. pyri to chlorantraniliprol and deltamethrin was investigated in order to assess their efficacy. Experiments were conducted in accordance with standard OEPP/EPPO methods, in field trials on test site in the Republic of Serbia (Kula), during 2021. Results of the field trials indicate good efficacy for all variants in pear psyllid control in pear orchards. The high efficacy ranging from 86 to 93%, was achieved 7 and 14 days after treatment, for both insecticides. Based on the obtained results it can be concluded that the high efficacy of the researched insecticides is a good indicator of C. pyri susceptibility in pear orchards. |
