Rapid differentiation of the sexes of adult <i>Mecinus janthinus</i> (Coleoptera: Curculionidae) based on external leg morphology
Bibliographic record
Abstract
The stem-boring weevil, Mecinus janthinus Germar (Coleoptera: Curculionidae), was introduced from Europe to Canada in 1991 to control the noxious weeds Dalmatian toadflax, Linaria dalmatica (L.) P. Mill., and yellow toadflax, Linaria vulgaris P. Mill. (Scrophulariaceae) (De Clerck-Floate and Harris 2002; McClay and De Clerck-Floate 2002). Since its release, M. janthinus has established well on Dalmatian toadflax in British Columbia (BC) and, to a lesser extent, southern Alberta (De Clerck-Floate and Miller 2002), and it is beginning to show promise as a successful control agent against this weed (De Clerck-Floate and Harris 2002). However, it appears that M. janthinus has not thrived on yellow toadflax in Alberta (McClay and De Clerck-Floate 2002).

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.
