Life Table and Population Parameters of<i>Schizaphis graminum</i>(Rondani) (Hemiptera: Aphididae) on Six Wheat Genotypes
Bibliographic record
Abstract
Biological parameters of Schizaphis graminum (Rondani) reared on an ancient wheat species (Einkorn) from England and five Iranian wheat genotypes (Azadi, Ommid, Marvdasht, Pishtaz and Moghan 2) were studied under controlled conditions at 22 ± 1°C, 65 ± 5% RH, 16:8 (L:D) h. The lowest rm value (0.261± 0.002 females/female/day) and net reproductive rate (R0) (28.747± 0.369) were recorded on Einkorn. The highest and the lowest finite rates of increase (λ) were on Moghan 2 and Einkorn, respectively. Also, the longest mean generation time (T) and doubling time (DT) with the lowest percentages of nymphal survival (79.5%) and fecundity over developmental time (35.739± 0.378 nymphs/female/day) were obtained on Einkorn. Adult longevity varied from 10.72± 0.123 days on Einkorn to 18.04± 0.212 days on Moghan 2. Therefore, our results showed that Einkorn, exerting a high level of antibiosis compared to other tested genotypes, may decrease the population density of the greenbug.

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.
