ABSTRACT SPATIOTEMPORAL DYNAMICS AND HOST SELECTION OF EMERALD ASH BORER, AGRILUS PLANIPENNIS (COLEOPTERA: BUPRESTIDAE), AT
Bibliographic record
Abstract
The emerald ash borer (Agrilus planipennis; EAB) is a wood-boring beetle that was introduced to North America from Asia c. 1990. Larval feeding on ash trees (Fraxinus spp.) has caused extensive mortality of North American ashes. This study was initiated in the early stages of an EAB infestation at Point Pelee National Park in Essex County, Ontario, Canada to monitor an infestation in a natural environment, and included assessment of tree health and quantification of beetle emergence. A plot containing green and blue ash trees was established in 2008. Green ashes were heavily infested; blue ashes showed no signs of colonization. By 2011, all green ashes were dead while EAB had emerged from few blue ashes. Emergence had declined dramatically. Blue ash trees are not expected to suffer severe mortality at this site due to EAB infestation. Crown health and EAB emergence was assessed in 620 ash trees in six plots from 2008 to 2011. Exit holes left by beetles in 2006 and 2007 were also counted. Emergence was low in 2006, peaked in 2009, then decreased again despite the availability of suitable

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.
