Further evidence that monochamol is attractive to<i>Monochamus</i>(Coleoptera: Cerambycidae) species, with attraction synergised by host plant volatiles and bark beetle (Coleoptera: Curculionidae) pheromones
Bibliographic record
Abstract
Abstract Monochamol (2-undecyloxy-1-ethanol) is a male-produced aggregation pheromone for severalMonochamusDejean (Coleoptera: Cerambycidae) species. We conducted trapping experiments in Canada, Poland, and China to test whether monochamol was attractive to additionalMonochamusspecies and if attraction was synergised by plant volatiles and bark beetle (Coleoptera: Curculionidae) pheromones. We provide the first evidence of attraction forM. urussovii(Fischer) andM. saltuarius(Gebler) to monochamol or monochamol+kairomones. The highest numbers ofM. urussoviiwere captured in traps baited with monochamol+plant volatiles (Manuka oil, ethanol and (95/5±) α−pinene). Captures ofM. saltuariuswere highest in traps baited with monochamol, with the addition of cubeb oil tending to reduce captures. The highest numbers ofM. scutellatus(Say) were captured in traps baited with monochamol+kairomones. A similar pattern in trap captures was found forM. notatus(Drury),M. marmoratorKirby,M. carolinensis(Olivier), andM. mutatorLeConte. Detection rates, that is, proportion of traps capturing at least one specimen, was highest for traps baited with monochamol plus kairomones, particularly for less-common species. These results support the emerging hypothesis that pheromone compounds can attract related cerambycid species with cumulative evidence for attraction to monochamol for 12 species ofMonochamusworldwide.

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.
