Abstract
Woolly apple aphid, Eriosoma lanigerum is one of the important apple pests in the Netherlands. Weather conditions and natural enemies determine whether woolly apple aphid (WAA) will reach pest status. WAA may escape control by natural enemies and therefore it must be controlled using chemical insecticides. To prevent unnecessary applications of insecticides and to promote biological and natural control of WAA more knowledge is needed about the role of natural enemies, weather and their effects on the development of WAA populations. The monophagous parasitoid Aphelinus mali (Hald.) has been introduced into most of apple growing areas to control WAA, but success is variable and depends on climatological conditions. In the Netherlands the level of parasitization is often too low, especially after warm winters. The biological control potential of a strain of A. mali from Nova Scotia (Canada) was compared with a Dutch strain by simulating population growth of both WAA and the Dutch and Canadian strain of the parasitoid for three different years The results indicate that the Canadian strain would perform in general better than the Dutch strain under Dutch weather 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
