Biology of Pieris Brassicae (Linn.) on Different Brassica Species in the Plains of Punjab
Bibliographic record
Abstract
Abstract Biology of Pieris brassicae reared on Brassica napus, B. juncea, B. rapa, and B. carinata was studied. Adult butterflies, collected in November from the plains of Punjab, India, were sexed, paired, and released onto the four Brassica spp. in a greenhouse. In a multigeneration study (Parental, F1, and F2), the effect of the four Brassica spp. on the egg laying, incubation period and hatching percentage was assessed in a greenhouse study. Hatched larvae were collected, reared on fresh leaves of respective Brassica spp, in laboratory conditions. Data collected on larval stadia, pre-pupal and pupal durations, adult longevity, and sex ratio were assessed to understand the effects of these four species. Of the four species, B. carinata, with a shorter incubation period, higher hatching percentage, and shorter developmental periods was most susceptible. In this study, B. rapa was the most resistant species and may be recommended for further breeding programs in order to reduce the economic damage caused by P. brassicae.

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.
