First record of damage by the red palm weevil, <i>Rhynchophorus ferrugineus</i> (Olivier, 1790) in sugarcane fields in China
Bibliographic record
Abstract
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
