Abstract：This study used systematic field surveys and pesticide trials to determine the occurrence，damage levels，and effective control measures for Corythucha ciliata （Say）on Platanus in Sanmenxia，with the aim of reducing pest damage. The results showed that C .ciliata occurred in four generations per year，with its annual occurrence period extending from mid -April to late October.The peak adult occurrence periods were late June for the first generation，lateJulyforthesecond，early September forthethird，and early October forthe fourth. The pest overwinters as fourth -generation adults.The severityof damage varied with planting age，being highest in Shanzhou Park，followed by Xiangchuan Road，and lowest in the Wetland Reserve.Within the tree canopy， damage severity was greatest in the lower part，folowed bythe middle，and lowest in the upper part.Pesticide trials showed that in 2O21，24 h after application，the corrected eficacies were 88.30% for 10% imidacloprid WP at 500-fold dilution， 87.40% for 1% emamectin benzoate EC at 2 OoO -fold dilution，and 87.02% for （20 1.2% matrine ⋅ nicotine EC at 5OO-fold dilution. In 2O22，the corresponding efficacies were 89.35% for 1% （2 abamectin EC at 2OoO-fold dilution， 87.70% for 10% imidacloprid WP at5OO-fold dilution，and 85.73% （204 for 1.2% matrine ⋅⋅ nicotine EC at 5Oo -fold dilution.No significant differences were observed among the three treatments，all of which could be applied in production.Theoptimal spraying time is during the peak period of the first - generation adults.
