Bibliographic record
Abstract
Lygus (Hemiptera: Miridae) are unpredictable pests in canola. This stems from their ability to produce multiple generations, having up to six species forming a “complex”, and a wide host plant range combined with highly variable canola growing regions in Canada. The number of generations and synchrony of Lygus adults and nymphs with canola varies across the growing regions of the Canadian prairies. The economic threshold for Lygus in conventional canola is well established for southern Manitoba. Other areas of the prairies, particularly the northern growing regions, have inherently different growing conditions that are likely to lead to different economic injury levels. This, combined with the advent and widespread adoption of new hybrid canola varieties, suggests that this unpredictable pest deserves new research efforts designed to examine the relationship between Lygus and current canola production systems. Further, a closer investigation of the natural enemies and unique growing conditions that contribute to the “unpredictable ” nature of Lygus outbreaks in canola is needed.

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.
