Patterns of parasitism by tracheal mites (Locustacarus buchneri) in natural bumble bee populations
Bibliographic record
Abstract
Parasitic mites are among the most destructive enemies of social bees. However, aside from mites of honey bees, virtually nothing is known about the prevalence and effects of parasitic mites in natural bee populations. In this paper, we report on parasitism of bumble bees (Bombus spp.) by the tracheal mite Locustacarus buchneri Stammer in south-western Alberta, Canada. Parasitism of bumble bees by L. buchneri occurred at many sites and in several host species. However, L. buchneri appears to be relatively host-species specific as it was found primarily in bumble bee species belonging to the subgenus Bombus sensu stricto. Furthermore, bumble bees containing tracheal mites had significantly reduced lifespans in the laboratory. Implications of parasitism on bumble bee life history are discussed.

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.
