Abstract
An ethyl acetate extract of Piper nigrum L. (Piperaceae) peppercorns was tested as a synergist for the botanical insecticide pyrethrum. A high synergist ratio of 11.6 against Drosophila melanogaster was obtained for the combination of pyrethrum supplemented with P. nigrum. The effect of this combination was investigated using cDNA microarray analysis of gene expression profiles in D. melanogaster. Treatment of D. melanogaster with pyrethrum alone resulted in a large number of differentially expressed genes, principally associated with stress responses. Seven genes were identified as being commonly expressed in D. melanogaster treated with at least two of the following treatments: P. nigrum, pyrethrum or P. nigrum plus pyrethrum. These are likely implicated in Drosophila defence responses to toxins.

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
