Interception and Eradication of <i>Lymantria</i> Moths in British Columbia, Canada: 50-Year History of a Thwarted Invasion
Bibliographic record
Abstract
Abstract The spongy moth ( Lymantria dispar dispar ) and several of its close relatives (subspecies L . d . asiatica and L . d . japonica , and the species L . umbrosa and L . albescens ) are defoliators that pose an invasion threat in Canada and around the world. Members of this group can disperse far beyond their native ranges on vehicles and freight, and they can attack a wide array of deciduous and coniferous plant species globally. Occasional population outbreaks can also defoliate large geographic areas over multiple years, resulting in widespread tree decline or mortality and a variety of other ecological impacts. As a result, these moths pose a serious threat to natural and urban forests. We summarize the history of Lymantria moth incursions into the province of British Columbia, Canada, since the start of regular surveillance and eradication began in that region near the end of the 1970s. Proactive public policy and a science-based management approach have contributed to a successful partnership between the federal and BC provincial governments to thwart a Lymantria moth invasion for nearly 50 years.

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.
