Abstract
Abstract The fir coneworm, Dioryctria abietivorella (Groté), is a transcontinental pest of coniferous seed cones. Recently, the attractive pheromone components and lure blend for the fir coneworm in western Canada were identified as a 200 µg : 2000 µg ratio of (9 Z ,11 E )-tetradecadienyl acetate (9 Z ,11 E -14:Ac) and a polyunsaturated hydrocarbon, (3 Z ,6 Z ,9 Z ,12 Z ,15 Z )-pentacosapentaene (C 25 pentaene). A potential third component, ( Z )-9-tetradecenyl acetate (9 Z -14:Ac), which was detected in pheromone gland extracts, had no effect on males of the western population when added to the binary blend. In contrast, in eastern Canada (Quebec) we found that the 200 µg : 2000 µg binary blend was unattractive to male fir coneworms until 9 Z -14:Ac was added. By means of several field experiments we established that a 67 µg : 200 µg : 2000 µg ratio of 9 Z -14:Ac, 9 Z ,11 E -14:Ac, and the C 25 pentaene was attractive to fir coneworms in Quebec. Gas chromatography - mass spectrometry analysis of pheromone gland extracts of fir coneworm from Quebec confirmed the presence of the three components in extracts in an approximately 1 µg : 4 µg : 10 µg ratio of 9 Z -14:Ac, 9 Z ,11 E -14:Ac, and the C 25 pentaene. Our results provide evidence that the eastern and western populations of D. abietivorella are distinct geographic pheromone races, with 9 Z -14:Ac being required for attracting males of the eastern population but not males of the western population.

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
