Abstract
A large number of proteins in salivary gland extracts of the leaffooted pine seed bug, Leptoglossus corculus Say, were strongly recognized by a polyclonal antibody-based assay developed for detecting saliva of the western conifer seed bug. Leptoglossus occidentalis Heidemann, in lodgepole pine, Pinus contorta var. latifolia Engelmann, seeds. An average of approximately 85% of loblolly pine, Pinus taeda L., seeds exposed to feeding by L. corculus for 1 to 4 weeks in the laboratory contained detectable amounts of salivary proteins when the antibody assays were performed weekly on samples (n = 10) of seed. In comparison, radiography of exposed seed detected an average of approximately 63% damaged seed over the same 4-wk period, indicating that the antibody assay increased sensitivity of damage detection by approximately one-third. Depletion of insoluble polypeptides and proliferation of soluble polypeptides ≤23.5 kDa was apparent after SDS-PAGE and quantitative assays were performed on proteins extracted from seeds that were damaged by exposure to L. corculus feeding. Our data suggest that the antibody-based test could be used to obtain accurate estimates of seed losses attributable to L. corculus feeding in southern pine seed orchards.

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 it
