Abstract
The contact toxicity and fumigant effect of Azadirachta indica A. Juss, Anacardium occidentale (L), Pipper guineense Schum and Thonn seeds powders and Pirimiphos methyl (Actellic) dust were evaluated against cowpea bruchid, Callosobruchus maculatus (Fab.). Contact toxicity assay show that A. indica and P. guineense powders have a comparative effect to synthetic insecticide, Pirimiphos methyl. Both were able to cause 100% mortality of C. maculatus at all tested concentrations (0.1, 0.2, 0.4 and 0.8g/20g of cowpea seeds) within 7 days of post treatment. However, in the fumigation assay, none of the plant powders was suitable as a fumigant since A. indica and P. guineense powders could only cause 23.3% and 20% mortality of adult cowpea bruchid respectively after 7 days of application. Pirimiphos methyl powder was good as a fumigant causing 100% mortality of C. maculatus after 7 days of application at all tested concentrations.

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
