Canada’s response to invasion by Asian longhorned beetle (Coleoptera: Cerambycidae) in Ontario
Bibliographic record
Abstract
Abstract A reproductive population of the Asian longhorned beetle,Anoplophora glabripennis(Motschulsky) (Coleoptera: Cerambycidae), an adventive insect from Asia, was discovered in 2003 in an urban landscape in Ontario, Canada. This polyphagous beetle, which attacks maples,Acerspp. (Sapindaceae), had the potential to seriously and permanently alter the composition and structure of forests in eastern North America. The Canadian Food Inspection Agency (CFIA) developed and implemented an eradication programme, with partners from various agencies in both Canada and the United States of America. Surveys were used to delineate the infestation and establish a regulated area around it. Treatment consisted of removing and destroying both trees with signs ofA. glabripennisinjury and trees assumed at high risk of being injured within the regulated area. After nine years of monitoring the regulated area, the CFIA declaredA. glabripenniseradicated on 5 April 2013. Herein, we detail the response undertaken, summarise lessons learned, and provide preliminary observations and results pertaining to the arrival, establishment, and spread ofA. glabripennisin Ontario.

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.
