Abstract
Contarinia nasturtii , the swede midge, is an invasive pest of vegetables and oilseed crops in the family Brassicacea. Larval feeding by swede midge damages the growing points of the host plant and can result in significant yield loss in both vegetable and canola crops. To date, swede midge is not established in western Canada, but a close relative, Contarinia brassicola , the canola flower midge, is widespread on the prairies (i.e., Manitoba, Saskatchewan, and Alberta) and is present in Ontario as well. Economic damage associated with C. brassicola appears to be rare. Foreign exploration for potential biological control agents of swede midge was conducted in Europe, where parasitoids were observed parasitizing swede midge larvae, but these species were not sufficiently host specific to justify further investigation for importation biological control. Sampling in western Canada has revealed that at least two parasitoids parasitize C. brassicola ; these species are likely undescribed. The chapter reviews the management and status of biological control research for both midge species.

How this classification was reachedexpand
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.
