Abstract
Since 2008, a wasp species has been observed to predate nymphs of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) (Fig. 1), the Asian citrus psyllid, one of the vectors of the bacterial patho gen Candidatus Liberibacter asiaticus, causal agent of the deadly citrus greening disease (Xuet al. 1998; Gamier & Bove 2000). The wasp species was identified as the Mexican honey wasp, Brachygastra mellifica (Say 1837) (Vespidae: Polistinae) by M. Buck. This wasp was first ob served attacking D. citri nymphs in 2008 in sweet orange, Citrus x sinensis (L.) Osbeck (Rutaceae), and lemon, Citrus x limon (L.) Burm. f. (Ruta ceae), groves, planted 3 to 5 yr ago in Rio Bravo, Tamaulipas, Mexico (25°56'39.12N, 98°07'3.9W, 28. 2 elev.). We have been observing B. mellifica since 2008 at Rio Bravo, and have found that its predatory activity is greatest during Jul through Sep when a high population of D. citri nymphs is present on new flush. B. mellifica are small ocial wasps (body length 7-9 mm), and are one of the few insect species, other than honey bees, that produce and store honey (Sugden & McAllen 1994). The species con

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
