Douglas-fir pitch moth,<i>Synanthedon novaroensis</i>(Lepidoptera: Sesiidae) in North-Central British Columbia: Flight Period and the Effect of Trap Type and Pheromone Dosage on Trap Catches
Bibliographic record
Abstract
The synthetic pheromone (Z,Z)-3,13-octadecadien-1-yl acetate was tested in two trap types and at different loads for trapping the Douglas-fir pitch moth, Synanthedon novaroensis (Henry Edwards) (Lepidoptera: Sesiidae), in a lodgepole pine, Pinus contorta Douglas ex Loudon variety latifolia Engelmann, provenance trial at the Prince George Tree Improvement Station, Prince George, British Columbia. This moth causes considerable problems in lodgepole pine seed orchards at this location. No significant differences in trap catches were found between wing traps and Unitraps in two experiments. There were no significant differences between catches in Unitraps baited with 50, 100, or 200 μg of the pheromone loaded on red rubber septa. In a second experiment, Unitraps baited with four rubber septa, each loaded with 200 μg for a total load of 800 μg, captured significantly more Douglas-fir pitch moths than those baited with one septum (200 μg) or two septa (400 μg) of the pheromone. All pheromone loads caught significantly more moths than unbaited control traps. Based on trap catches in these trap bioassays, and catches in monitoring traps in four lodgepole pine seed orchards, 1996 through 2000, the flight period of S. novaroensis in north central British Columbia normally starts in early June, and lasts for 4–7 wk.

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.
