Isolation of Bacillus From the Gut of Bombus terrestris and Its Correlation in Queen Mating
Bibliographic record
Abstract
The gut of bumblebees harbors bacteria that play a crucial role in physiology, nutrition, and health. The mating rate is important for the reproductive activity of a colony; however, few studies have investigated the relationship between mating and gut bacteria. In this study, bacterial functions were identified in the intestinal tract of bumblebees, and biochemical identification and screening were performed using genetic detection technology. By isolating and identifying bacteria, we obtained a single strain and fed it to queens. The results indicated that Bacillus cereus and Bacillus pumilus are present in the gut. The queen mating rates were 48.89% at the period of 4 days and higher than 28.89% mating rates of the control group (P < 0.05), and the latency time were 16.90 min (from entering the mating cage to mating success) and decreased than control (P < 0.05) which was 28.20 min. This finding confirmed that Bacillus was important in Bombus terrestris mating.

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.
