Abstract
Abstract The recent shift of Rhagoletis pomonella Walsh (Diptera: Tephritidae) from its ancestral host hawthorn to apple is a model for incipient sympatric speciation in action. Previous studies have shown that changes in the over‐wintering pupal diapause are critical for differentially adapting R. pomonella flies to a difference in the fruiting times of apples vs. hawthorns, generating ecologically based reproductive isolation. Here, we exposed pupae of the hawthorn race to various combinations of pre‐ and over‐wintering rearing conditions and analyzed their effects on eclosion time and genetics. We report certain unexpected results in regards to a combination of brief pre‐winter and over‐wintering periods indicative of gene*environment interactions requiring a reassessment of our current understanding of R. pomonella diapause. We present a hypothesis that involves physiological factors related to stored energy reserves in pupae that influences the depth and duration of Rhagoletis diapause. This ‘pupal energy reserve’ hypothesis can account for our findings and help clarify the role host plant‐related life history adaptation plays in phytophage biodiversity.

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
