Abstract
Anastrepha fraterculus is a cryptic species complex with at least eight morphotypes distributed across the Americas. Among them, A. fraterculus sp.1, present in Argentina, is a major pest impacting fresh fruit production. Integrated pest management strategies, including chemical control and trapping, are currently employed to mitigate its effects. Genetic sexing strains of A. fraterculus sp.1 are being evaluated for use in sterile insect technique programs. To support traditional and emerging control methods, this study aimed to enhance the genomic understanding of this morphotype. Individual female and male samples were sequenced using long- and short-read technologies. The female genome (760 Mb) was de novo assembled into 58 scaffolds and the male genome (750 Mb) into 68 scaffolds, with BUSCO completeness scores of 98.8% and 98.7%, respectively. Synteny analysis revealed complete scaffolds of the five autosomes and enabled near-complete reconstruction of the X and Y chromosomes. Gene prediction identified 17 751 and 16 535 protein-coding genes (for female and male genomes, respectively), with repetitive regions representing 46% of both genomes. Additionally, the mitochondrial genome was fully assembled and annotated. This comprehensive genomic resource reveals candidate genes for functional studies, including gene editing and RNA interference, as successfully applied in related tephritid species. These findings lay the foundation for innovative, complementary biocontrol tools against A. fraterculus.

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
