Abstract
European Gypsy Moth (Lymantria dispar) is an invasive alien pest that was first found in Ontario in 1969. Its population fluctuates in relation to environmental and biological controls. This pest cannot be eradicated. In 2006, 2007 and 2008, Toronto implemented control measures when European Gypsy Moth populations attained outbreak levels. Those measures were successful in reducing the population to acceptable levels. Current surveys indicate European Gypsy Moth population levels have reached outbreak levels in some areas of Toronto, requiring intervention in order to mitigate the impact of this forest health threat. This report presents the interim results of the survey along with recommended control measures, which include an aerial spray of Bacillus thuringiensis subspecies kurstaki (Btk) in the larger outbreak areas. At present, aerial spraying is proposed in Wards 2, 3, 4, 5 and 27. Ground based spraying, tree injection and egg mass removal is proposed for other locations throughout the city. This control strategy is expected to reduce the European Gypsy Moth population and expected levels of defoliation, resulting in prevention of tree loss or significant decline. RECOMMENDATIONS The General Manager of Parks, Forestry and Recreation recommends that: 1. City Council authorize Urban Forestry staff to implement, where necessary in Wards 2, 3, 4, 5 and 27 and other wards as determined by surveys, an integrated pest management (IPM) program involving aerial and ground spraying of a Staff report for action on Control of European Gypsy Moth Outbreak in the City of Toronto 1 biological control agent, Bacillus thuringiensis subspecies kurstaki (Btk), injecting individual trees with TreeAzin TM and mechanical egg mass removal. 2. City Council direct Urban Forestry staff to consult with Toronto Public Health, Transportation Services and Toronto Police Service to coordinate implementation of the proposed aerial and ground based application of the biological control agent

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.
