Abstract
Resistance level of seven accessions of wild Solanum species ( Solanaceae ) to Myzus persicae and Macrosiphum euphorbiae (Homoptera: Aphididae ) was evaluated by measuring survival and fecundity during sleeve cage experiments and population growth on whole plants in a controlled environment. The survival was lowest on the Solanum circaeifolium spp. capsicibaccatum , Solanum pinnatisectum and Solanum trifidum accessions for M . persicae and on the S . circaeifolium spp. capsicibaccatum , Solanum okadae and S . trifidum , accessions with M . euphorbiae . Plant species significantly influenced the fecundity of both aphid species. Aphid population growth on whole plants was negatively affected by the age of the plant, but generally followed the levels of net reproductive rate on different plant species observed during the sleeve cage experiment. The population of M . persicae varied among the seven wild potato accessions with the lowest growth rates on S . circaeifolium spp. capsicibaccatum , Solanum polyadenium , Solanum tarijense and S . trifidum . The number of M . euphorbiae also varied among accessions but the smallest population was collected from S . polyadenium . The results can be used to identify sources of resistance to aphids within those accessions already known to be resistant to the Colorado potato beetle. This study highlights the difficulties involved in developing a high‐throughput screening test for aphid resistance compatible with a potato breeding programme.

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
