Hairy canola deters flea beetle feeding
Bibliographic record
Abstract
Flea beetle, chiefly Phyllotreta crucifrerae, behaviour and feeding on lines of Brassica napus canola with elevated levels of trichomes on true leaves were compared with feeding on leaves of parent seedlings.The beetles became agitated and seldom settled down to feed when exposed to the hairy seedlings.Levels of feeding on the new lines were measured in a laboratory trial at Saskatoon, and in field trials at Saskatoon (2005Saskatoon ( , 2006) ) and Lethbridge (2006).Initially, feeding levels were lower on cotyledons of the recombinants than on those of the parental line, possibly because of the increased angle of recombinant cotyledons relative to the soil surface.As cotyledons became more horizontal on recombinant seedlings, feeding upon them increased, but feeding on true leaves of the transgenic lines was less than on true leaves of parental lines The decreased feeding on true leaves of recombinant seedlings is a first step in developing canola resistance to the insect.

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.
