Abstract
Effective biological control of Lygus lineolaris and Adelphocoris lineolatus depends on the availability of appropriate host stages to sustain populations of euphorine parasitoids which are important in reducing pest populations.In Quebec alfalfa, crops are cut 2-A times during the summer season, yet how this affects the host and parasitoid populations is poorly understood.A 3-year study conducted from 2000-2002 in southern Quebec demonstrated that overall, abundance of susceptible host stages (N2+N3) in cut alfalfa were less than half of those collected in uncut alfalfa, even after 4-5 weeks when the cut crop reached the same height as the uncut crop.Parasitism levels of N4+N5 nymphs in the cut crop were usually less than those in the uncut crop, although on several sampling dates the reverse was observed.Numbers of adult L. lineolaris and A. lineolatus were always lower immediately after harvest in the cut crop but numbers increased in the following weeks to equal those collected in the uncut crop.These results suggest that periodic harvest of alfalfa reduces available host stages for parasitism and subsequent levels of parasitism but does not cause elimination of parasitoid populations.Furthermore, dispersing adults likely contributed to an increase in abundance of susceptible host stages after habitat modification, thereby sustaining parasitoid populations.
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.

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.
