Scientific Opinion on the pest categorisation of Rhagoletis ribicola
Bibliographic record
Abstract
The EFSA Panel on Plant Health undertook a pest categorisation of the insect Rhagoletis ribicola for the European Union. This taxonomically distinct species is known to occur only in western states of the USA and Canada, where it feeds on Ribes aureum, R. rubrum and R. uva-crispa. There have been no records of it causing serious damage for over 70 years. Its geographical distribution implies that all parts of the risk assessment area where its hosts occur, i.e. all but lowland southern areas of the EU, would be suitable for establishment. Adults of the Rhagoletis genus have a limited capacity for flight. Furthermore, there are no records of R. ribicola moving via international trade routes. Therefore, spread would be most likely to occur as a result of larvae in fruit or pupae in soil. Should the pest be introduced to the EU, the limited control measures available would be similar to those used for other Rhagoletis species, being primarily based on insecticide sprays, timed to kill adults, combined with cultural methods, e.g. netting and trapping. As a non-European tephritid, R. ribicola is listed in Annex IAI of Council Directive 2000/29/EC, and requirements for Ribes are set out in Annex V of Council Directive 2000/29/EC. In addition, Ribes spp. plant material should be produced in accordance with the requirements laid down in Council Directive 2008/90/EC on the marketing of fruit plants propagating material and fruit plants intended for fruit production.

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.
