Abstract
Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), European corn borer, is an economic pest of Zea mays (Linnaeus) (Poaceae) and other vegetable crops that is distributed throughout the agricultural production regions of Ontario, Québec, and Manitoba in Canada. Two phenotypic races of O. nubilalis have been identified that differ in the proportion of isomers of 11-tetradecenyl acetate (11-14:OAc) in their sex pheromone. The Z-race (Z-11-14:OAc) is the predominant race in the United States of America, known to inhabit Zea mays as its primary host, whereas the E-race (E-11-14:OAc) infests a wider host range, including many vegetable crops, and is only found within the Eastern coastal states of the United States of America. Collections of O. nubilalis were made from grain corn in agricultural regions of Ontario, Québec, and Manitoba in 1997, 2008, 2009, and 2010, and females were analyzed for pheromone race using gas chromatography (GC). Only Z-race O. nubilalis were found in Ontario (from Essex to Leeds and Grenville Counties) and in Southern Manitoba. E-race individuals were detected in collections from Ottawa, Ontario and St. Anicet, Québec, with an increasing proportion of E-race phenotypes in samples from west to east. This is the first report of pheromone race determination using GC among Canadian O. nubilalis populations and the first documentation of E-race O. nubilalis in Canada using GC.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
