Comparative demography of <i>Nilaparvata lugens</i> (Stål) reared on Bt rice and non‐Bt rice
Bibliographic record
Abstract
Abstract The insect‐resistant rice variety mfb‐MH3301‐1, expressing Cry1Ab, has demonstrated robust resistance against Lepidopteran pests. However, its potential effects on non‐target organisms warrant further investigation. This study evaluated the effects of mfb‐MH3301‐1 in comparison with the parental rice variety MH3301 ( Oryza sativa L.) on the development of the insect pest Nilaparvata lugens (Stål) (Homoptera: Delphacidae). The results showed that there were no significant differences in female longevity, male longevity, lifespan, and mean generation time ( T ) between brown planthoppers fed on either mfb‐MH3301‐1 or MH3301. However, N. lugens individuals fed on mfb‐MH3301‐1 exhibited significantly higher fecundity, intrinsic rate of increase ( r ), finite rate of increase ( λ ), and net reproductive rate ( R 0 ) compared to those fed on MH3301. The study provides valuable insight into the management of N. lugens in the future cultivation of Bt rice, and attention should be paid to the population dynamics of N. lugens in the field.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
