Baseline Susceptibility of Striacosta albicosta (Lepidoptera: Noctuidae) in Ontario, Canada to Vip3A Bacillus thuringiensis Protein
Bibliographic record
Abstract
Striacosta albicosta (Smith; Lepidoptera: Noctuidae) is a pest of corn (Zea mays L.), which has recently expanded its range into Ontario, Canada. Genetically modified corn expressing Vip3A insecticidal protein from Bacillus thuringiensis is a biotechnological option for the control of S. albicosta. To support an insect resistance management program, we conducted a study of baseline susceptibility of 10-field collected S. albicosta populations in Ontario, Canada to Vip3A before widespread commercial adoption. Neonates were exposed to artificial diet overlaid with Vip3A. The LC50 ranged from 22.7 to 53.5 ng Vip3A cm-2. The EC50 ranged from 11.4 to 30.2 ng Vip3A cm-2. There was low inter-population variation in susceptibility to Vip3A, which we believe represents the natural geographical variation in response and not variation caused by previous exposure to selection pressure of the Vip3A protein.

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.
