Stimulating effect of bark polar fraction from the terminal leader of Norway spruce, <i>Picea abies</i>, on white pine weevil, <i>Pissodes strobi</i>, feeding and oviposition
Bibliographic record
Abstract
Abstract: The objective of the study was to demonstrate the importance of bark polar fraction from Norway spruce [ Picea abies (L.) Karst.] terminal leaders on the feeding activity and oviposition process of the female white pine weevil, Pissodes strobi (Peck). The bark polar fraction was extracted with a ternary solvent [chloroform, methanol and water (12 : 5 : 3)]. This extracted fraction was added, at different concentrations, to an artificial diet on which mated female white pine weevils could feed and oviposit. The bark polar fraction of Norway spruce terminal leaders promoted white pine weevil oviposition compared with untreated artificial diet. The results of this study contributed to the development of an efficient artificial rearing substrate required to better understand the interactions between white pine weevil and its host plants. The importance of more specific compounds found in the polar fraction could eventually help produce more resistant trees.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
