Plant resistance and alternative management to Lygus lineolaris (Palisot de Beauvois), tarnished plant bug, in strawberry genotypes, Fragaria x ananassa, and raspberry, Rubus ideaus L.
Bibliographic record
Abstract
Tarnished plant bug feeds on developing seeds and fruit tissue of strawberries. The wild species 'Fragaria virginiana' displays resistance and has been crossed with commercial day-neutral strawberries, producing resistant hybrids. The purpose of this study was to elucidate possible mechanisms of resistance and rank the resistance of hybrids. The effect of pollen load was also examined. Field trials compared four commercial day-neutral cultivars on three farms in southern Ontario on a weekly basis. Cultivar Fort Laramie consistently had lower damage compared to other cultivars at all sites. Laboratory experiments verified resistance and assessed the relationship of pollen to fruit damage. Caged choice and no-choice bioassays determined families 703, 704 and 708 and Fort Laramie consistently showed resistant qualities and reduced damage. Susceptible plants with pollen had higher damage and resistant plants did not. This study shows resistant genotypes were consistent and that pollen load plays a role in susceptibility.

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.
