Studies on antifeeding activity of Daphne tangutica against tobacco cutworm, Spodoptera litura.
Bibliographic record
Abstract
Insecticidal activity of Daphne tanutica, a local endemic plant from Qinghai-Tibet plateau, was first reported in this paper. The air-dried and powdered plant was extracted with methanol, acetone, ethyl acetate, chloroform, benzene and petroleum ester, and the results showed that foe extractive rate in methanol was the largest (22. 34% ), and the smallest (2. 21% ) in petroleum ester. The crude extracts of former five solvents were proved to possess strongly antifeeding effect on the 3rd instar larvae of tobacco cutworm, Spodoptera litura, through the preliminary bioassay with AFC50s of 108. 72, 111. 69, 102. 14, 71. 15 and 65. 51 g dried powder/L. At concentration of 500 g dried powder/L, antifeedant effect of the petroleum ester extract against the tested insects was 62. 31 %. Therefore benzene was the most effective extracting solvent.

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.
