Résumé : The red palm weevil, Rhynchophorus ferrugineus is one of the alien species of high risk in China and a key pest of palm trees. This paper presents the first status report of the damage caused to sugarcane by R. ferrugineus in China. The first observation of damage was recorded in Changling farm in Shangsi County, Guangxi Province, on a small plot in October 2017 and the recorded damage level, exceeded 80% with cane stalks completely destroyed. In September 2021, R. ferrugineus was found in sugarcane fields (11.85 hm2) in Liucheng County, in Liuzhou City, but the percentage of plant damaged was sporadic and didn't exceed 1%. The mean percent of damaged stalks and the length of damaged tunnels in plants recorded were 0.76%, and 19.54 cm, respectively when the canes were harvested. This discovery allowed us to prevent potential establishment and spread of the red palm weevil in the sugarcane regions in China, as well as serve a warning notice for other sugarcane regions worldwide.
