Effect of Methanolic Extracts from Susceptible and Resistant Rice Varieties on Brown Planthopper,Nolaparvata lugens(stl) ( Homoptera:Delphacidae)
Bibliographic record
Abstract
Effect of methanolic extracts of rice from resistant variety IR36 and susceptible variety TN1 were tested on Nolaparvata lugens(stl)(Homoptera: Delphacidae).48 h after,two treatments of TN1 plant spraying with extract of IR36 and controlt,heir density percent were 14.00% and 26.67%,egg number 16.0 and 52.2,honey-dew excreting 5.7 mg and 33.3 mg and body-mass increase rate-22.2% and 166.7%,respectively.Density percentage of the other two treatments,IR36 plant spraying with extract of TN1 and control,were 5.33% and 1.20%,egg number 24.4 and 0,honey-dew excreting 13.4 mg and 3.5 mg and body-mass increase rate 77.8% and-22.2%,respectively.The results show that extract of resistant variety IR36 is very effective to the ovientation,oviulation and feeding of N.lugens(stl).On the contrast,while susceptible variety TN1 has reverse effect.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
