Cacopsylla pyri (Hemiptera: Psyllidae) is one of the most significant pests threatening pear production in Türkiye, particularly in Antalya province, where pear cultivation is highly concentrated. This study aimed to determine the distribution, infestation rates, and population fluctuations of C. pyri in eight major pear-growing districts of Antalya between 2022 and 2024. To determine the infection rate, one hundred shoots from all four sides of pear tree were examined. Shoots with individuals or honeydew in the examined trees were evaluated as infested. In addition, yellow sticky traps were hung in three pear orchards to Elmalı district to determine the population fluctuation of the pest and counted weekly. Population fluctuation was carried out on Karyağdı, Deveci and Margaret pear varieties. It was determined that the pest was widespread in Korkuteli and Elmalı where pear production is intensive as well as in Alanya, Kaş, Gazipaşa, Serik and Manavgat districts except Döşemealtı district. Infestation rates of C. pyri were found to be 52.06, 69.67, 48.37, 19.88, 28.55, 21.71 and 1.60% in Korkuteli, Elmalı, Alanya, Kaş, Gazipaşa, Serik and Manavgat districts, respectively. While the highest number of adults counted in yellow sticky traps was reached in late June 2022, it changed according to the orchards in 2023. These results provide useful information on Pear psyllid monitoring and control.
