Interceptions and captures of Halyomorpha halys (Hemiptera: Pentatomidae) in Quebec from 2008 to 2018
Bibliographic record
Abstract
The brown marmorated stink bug, Halyomorpha halys (Heteroptera: Pentatomidae), was monitored in southern Quebec through a network of 137 baited pyramid traps deployed in urban and rural habitats between 2014 and 2017. Overall, 73 adults and 9 nymphs were captured. The first capture in rural (an apple orchard) and in urban areas (in Montreal) were observed in 2016. In that same year, 87% of the 54 individuals (adults) caught in Montreal were from a single trap. Similarly in 2017, only two adults were captured in rural habitats and 87% of the 25 captures (16 adults and 9 nymphs) in urban habitats were from the same trap as in 2016. This trap was the only one in which nymphs of various stages were collected, which suggests population establishment in Montreal. Haplotyped specimens from this site (four adults and two nymphs) were all of the H1 haplotype. Over 40 interceptions and sightings by citizens during the period 2008-2018 are also reported.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
How this classification was reachedexpand
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.
