Adult Movement and Host-Orientation Behaviour of Warren Root Collar Weevil, Hylobius warreni Wood (Coleoptera: Curculionidae).
Bibliographic record
Abstract
Warren root collar weevil, Hylobius warreni Wood, is a native insect found throughout Canada's boreal forest. In British Columbia, the weevil's primary host is lodgepole pine, Pinus contorta var. latifolia. While adults inflict minimal damage upon their hosts, larval feeding can girdle young trees, potentially causing tree death. Little is known about weevil host-orientation, particularly with respect to timing and extent of movement among host plants. I examined movement of adult weevils in different habitats using harmonic radar, and found that the highest movement rates occurred in areas without trees. Insect movement decreased with decreasing ambient air temperature and increasing time since release. In separate experiments in field arenas, I found that these flightless insects would walk toward vertical silhouettes in the shape of a tree. Blinding the insects obscured this behavior, suggesting that adult insects primarily use visual cues rather than chemical cues in host-finding behaviour. These findings may aid in the development of management strategies in plantations at high risk of weevil-induced mortality. --P. ii.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
