Experimental analysis of the mating system of the white pine weevil,<i>Pissodes strobi</i>(Peck) (Coleoptera: Curculionidae)
Bibliographic record
Abstract
The white pine weevil, Pissodes strobi, severely restricts the growth and range of Sitka spruce (Picea sitchensis) in British Columbia. Knowledge of the patterns of male and female mating success is important for designing biocontrol programs and for understanding the reproductive potential of this weevil. To examine patterns of male and female reproductive success, we performed experiments in which the numbers of competing mates were varied, and used microsatellite markers to assay for mating success. Matings were conducted under four regimes: two males competing for a female, four males competing for a female, two females competing for a male, and four females competing for a male. We assayed 1869 progeny among several replicates for four marker loci. We found considerable multiple paternity, and the variance of reproductive success was higher in males than in females. The normalized variance of male success was higher among four competing males than between two competing males, which is consistent with last-male sperm precedence, while the normalized variance of female success was independent of female number for a constant male number, indicating that sperm quantity was not a limiting factor for reproduction at these mate densities.

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.
