Abstract
Abstract The A merican cherry fruit fly is an invasive pest species in E urope, of serious concern in tart cherry production as well as for the potential to hybridize with the E uropean cherry fruit fly, R hagoletis cerasi L . ( D iptera: T ephritidae), which might induce new pest dynamics. In the first E uropean reports, the question arose whether only the eastern A merican cherry fruit fly, R hagoletis cingulata ( L oew) ( D iptera: T ephritidae), is present, or also the closely related western A merican cherry fruit fly, R hagoletis indifferens C urran. In this study, we investigate the species status of E uropean populations by comparing these with populations of both A merican species from their native ranges, the invasion dynamics in G erman (first report in 1993) and H ungarian (first report in 2006) populations, and we test for signals of hybridization with the E uropean cherry fruit fly. Although mt DNA sequence genealogy could not separate the two A merican species, cross‐species amplification of 14 microsatellite loci separated them with high probabilities (0.99–1.0) and provided evidence for R . cingulata in E urope. G erman and H ungarian R . cingulata populations differed significantly in microsatellite allele frequencies, mt DNA haplotype and wing pattern distributions, and both were genetically depauperate relative to N orth A merican populations. The diversity suggests independent founding events in G ermany and H ungary. Within each country, R . cingulata displayed little or no structure in any trait, which agrees with rapid local range expansions. In cross‐species amplifications, signals of hybridization between R . cerasi and R . cingulata were found in 2% of R . cingulata individuals and in 3% of R . cerasi . All putative hybrids had R . cerasi mt DNA indicating that the original between‐species mating involved R . cerasi females and R . cingulata males.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
