Abstract
Abstract The sex pheromone of female Heterodera schachtii, the sugar beet cyst nematode, was partially isolated using high performance liquid chromatography (HPLC). Female-conditioned medium (FCM), produced by incubating 20 H. schachtii females in 1 ml of ultrapure water, attracted males in a concentration dependent manner. The attractive material was not contained within the female gelatinous matrix and did not attract second stage juveniles (J2). Characterisation of FCM revealed that the attractive material was water soluble and heat stable. Male H. schachtii exhibited stylet thrusting behaviour upon exposure to FCM, and this behaviour was used as a novel indicator of biological activity.

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
