Occurrence of <i>Rhagoletis</i> species in Newfoundland
Bibliographic record
Abstract
Abstract The presence of Rhagoletis fruit flies in Newfoundland, Canada, was investigated by rearing large numbers of the fruits of known and potential host plant species. Three Rhagoletis species, R. tabellaria (Fitch), R. basiola (Osten Sacken), and the cherry pest species R. fausta (Osten Sacken), were found to occur naturally in Newfoundland, representing a range extension of some 500 km for R. tabellaria and R. basiola. Rhagoletis fausta had previously been reported from sticky traps used to monitor R. mendax Curran, which is not known from the province. To investigate the route by which the two new species may have colonized Newfoundland, R. tabellaria adults were sequenced for a mitochondrial genome fragment (COI–tRNA‐Leu–COII–tRNA‐Lys). This sample was genetically identical or similar to samples from other widely distributed sites in North America, suggesting that the presence of R. tabellaria in Newfoundland is the result of postglacial dispersal rather than survival in a glacial refugium. The implications of these findings for Rhagoletis management in Canada are discussed.

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.
