Abstract

fetched live from OpenAlex

The study was conducted to evaluate the insecticidal potency of Newbouldia laevis  extracts against Sitrotoga cerealella  in the laboratory at temperature of 28±2°C and relative humidity of 75±5%. Oil from the leaf, stem bark and root bark of N. laevis  was extracted using methanol as solvent and 1, 2, 3, 4 and 5% concentration of each oil extract were prepared. Results obtained revealed that oil extracted from all the parts of the plant had significant effect on the mortality of the moth but the root bark oil extract appeared to be most effective since it was the only one to achieve 100% insect mortality within 72 h of application at 4% concentration and it requires low concentration1.59 (LC 50 ) to achieve 50% mortality. The extracts reduced the adult emergence of the insect and their ability to cause seed weight loss. Both leaf and root extracts at 4 and 5% concentration prevented adult emergence while seed weight was prevented by all the three plant parts at 4 and 5% concentration. Water absorption capacity as well as viability of the protected paddy was not affected by the oil extracts. Nonetheless, there were significant differences between treatments and the controls in all the parameters tested except for water absorption capacity and viability test. The result obtained presented root extract of N. laevis  to be more effective than other plant parts and therefore could be introduce as a counter measure for the control of S. cerealella in storage.

Teacher imitation

Not 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.
