<i>Delia antiqua</i>Meigen, Onion Maggot / Mouche de l’oignon (Diptera: Anthomyiidae)
Bibliographic record
Abstract
Delia antiqua , the onion maggot, is a pest of plants in the genus Allium , including onions, scallions, garlic and chives. The larvae develop through three larval instars while feeding on below-ground plant structures, resulting in direct yield loss when seedlings are killed and because feeding on the bulb reduces marketability. Management of onion maggot relies heavily on insecticides, some of which are no longer available for use in Canada. Natural enemies of onion maggot include fungal pathogens (e.g., Entomophthora muscae , Beauveria bassiana ), entomopathogenic nematodes (e.g., Heterorhabditis bacteriophora ), arthropod predators and parasitoids (e.g., Aleochara bilineata ). Sterile insect technique has been used to manage onion maggot in eastern Canada since 2011. Most growers using sterile insect releases no longer use insecticides and the area being treated with sterile insect technique in Quebec has greatly increased since 2011.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
