Abstract
ABSTRACT Laboratory and field studies were conducted to measure the responses of adult codling moth, Cydia pomonella (L.), to several plant volatiles presented alone and in combination with acetic acid. Plant volatiles included ethyl (E,Z)-2,4-decadienoate (pear ester), (E)-β-farnesene, (Z)-3-hexenyl acetate, ± farnesol, and (E)-4,8-dimethyl-l,3,7-nonatriene (DMNT). Male codling moth exhibited upwind behavioral responses to each compound in flight tunnel tests with acetic acid > DMNT > ± farnesol > (Z)-3-hexenyl acetate > pear ester > (E)-β-farnesene. In apple orchards, however, only pear ester was an effective lure when used alone with clear pane traps. Choice tests in a flight tunnel with delta traps baited with DMNT plus acetic acid caught significantly more male and females than unbaited traps and significantly more females than DMNT-baited traps. Combining pear ester or DMNT loaded in septa lures with separate vials containing acetic acid significantly increased both male and female moth catch compared with the plant volatile alone, acetic acid alone, and unbaited pane traps in field trials. Similar results were not obtained with the other three plant volatiles. Septum loadings of 1 and 10 mg with either pear ester or DMNT in combination with acetic acid caught similar numbers of moths in orange delta traps. Sixty to 75% of the moths captured in traps baited with DMNT plus acetic acid were females. Moth catches in traps baited with DMNT plus acetic acid were ≈40% of catches in similar traps baited with pear ester plus acetic acid.

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
