Abstract
Abstract Aphid–ant associations are often described as mutually beneficial interactions in which honeydew is traded for protection from predators and parasitoids. The aim of the present study was to determine parasitization avoidance in ant‐tended aphid colonies. Field experiments were carried out on two host plants: hoary cress Lepidium draba (Brassicaceae) and Canadian teasel Cirsium arvense (Asteraceae). Lepidium was host to Acyrthosiphon gossypii (Aphididae) tended by the ant Lasius turcicus (Formicidae) and attacked by two parasitoids, Trioxys asiaticus (Braconidae) and Lysiphlebus fabarum (Braconidae). Cirsium was host to Brachycaudus cardui tended by Crematogaster sordidula and attacked by L. fabarum and Aphidius colemani (Braconidae). The per capita population growth rate of A. gossypii was significantly higher in the presence of ants, while B. cardui was negatively affected, albeit non‐significantly. The parasitism rate of A. gossypii decreased significantly when tended by Lasius turcicus , but the presence of Crematogaster sordidula in colonies of B. cardui significantly increased parasitism. Our results indicate that the effects of ant attendance vary between different aphid–ant interactions. Moreover, parasitoids can benefit from the presence of ants under some conditions.

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
