Bibliographic record
Abstract
Abstract Mark–release–recapture was used to investigate the dispersal of click beetles in spring wheat or fallow fields using edge or centre field releases. Three types of pitfalls were used: gutter traps near field margins, as well as conventional pitfall traps or cross‐traps consisting of four gutter trap arms leading to a central pitfall. Capture of naturally occuring beetles was concurrently recorded. In total, 6952 marked A griotes obscurus (males and females) and A griotes lineatus (males) were released and 14.74% were recaptured at some time during the present study. Recovery rates ranged from 3.54% to 28.5%. A griotes obscurus dominated wild populations, with 4011 males and 1672 females trapped compared with 17 males and three females for A . lineatus . Males dominated early in the period, although the sex ratio tended towards equality as the season progressed. Generally, captures of A . obscurus males released in equal numbers at field edges followed a uniform distribution. There were differences for wild beetles caught in the same traps. Spatial trapping patterns of wild and marked beetles across the fields were similar. Within 19 h of release at the field edges A . obscurus males were captured >30 m away. The crop type had a significant interspecific effect on trap counts for males and an intraspecific effect on A . obscurus females, reinforcing the need for caution when using trapping systems to monitor adult stages of these pests. The results of the present study demonstrate that uncropped field margins comprise sources of click beetles. We also conclude that click beetles disperse much further than reported previously.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
