Construction and analysis of the natural population life table for continuous generation of the diamondback moth, Plutella xylostella L.
Bibliographic record
Abstract
Based on the data of systematic survey in the field and observation in the laboratory, the natural population life tables of continuous two generations of the diamondback moth (DBM) , Plutella xylostella L., were constructed on one cropping of flowering Chinese cabbage in Shenzheng, Guandong Province. The results showed that the indices of population trend of two continuous generations of DBM were 11. 9 and 24. 4, respectively in spring and autumn. Parasitoids played a determinant role in the control of natural population of DBM. In spring, the important factor influencing the natural population of DBM was the larval-pupae parasitoid, Oomyzus sokolowsakii (Kurdjumov), which exclusive index of population control (EIPC) reached 8. 28. While the EIPC of Cotesia plutellae Kurdjumov was 4. 85. In autumn, C. plutellae was the secondly important factor influencing the natural population of DBM, which EIPC was 3. 67. The low EIPC (1 .2) of O. sokolowsakii caused a high population increase of DBM in autumn.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
