New record of<i>Chrysomya rufifacies</i>(Diptera: Calliphoridae) in Canada: predicted range expansion and potential effects on native species
Bibliographic record
Abstract
Abstract This is the first report of the hairy maggot blow fly,Chrysomya rufifacies(Macquart), in Canada since its arrival in the continental United States of America in 1982. Specimens were collected from one swine (Sus scrofaL.) carcass in fall 2004 and again from six swine carcasses at three rural sites within the Windsor/Essex County region of southwestern Ontario in fall 2005. Based upon the biological characteristics of the species and the absence of specimens from spring and summer carrion-insect collections, it is suggested thatC. rufifaciesis present in southwestern Ontario during the fall season, after range expansion from the midcontinental United States of America during the spring and summer months. However, considering the projected increases in temperature due to global warming, establishment ofC. rufifaciesis predicted to extend well into southern Ontario and Quebec. Current and predicted distributions based upon the biological temperature requirements ofC. rufifaciesare depicted through geographic range maps. The potential economic and ecological impacts are discussed, with emphasis upon negative interactions betweenC. rufifaciesand several native blow fly species, particularlyCochliomyia macellaria(Fabr.).

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.
