Abstract
Abstract The cereal leaf beetle, Oulema melanopus (Coleoptera: Chrysomelidae), is a new invasive pest of cereals in western Canada. Host plant resistance is a potential option in the integrated management of this insect. Wheat (Triticum aestivum L.) genotypes are known to possess antixenosis against O. melanopus; however, mechanisms involving antibiosis are relatively less explored. We present results of an investigation exploring antibiotic resistance in wheat germplasm of Central Asian origin with putative resistance to O. melanopus. Our laboratory assessment of development and survivorship of O. melanopus on test genotypes indicated antibiotic properties in four of the six genotypes evaluated. Antibiosis effects were reflected through lower survivorship, extended developmental periods and low adult fitness. However, two genotypes were excellent hosts, and beetles had higher survivorship and fitness on them. The performance of O. melanopus on these two genotypes was comparable to that on the susceptible genotype CDC GO included as a check. The genotypes with antibiotic resistance identified by this research can now serve as sources of genetic resistance for breeding cultivars adapted to western Canadian conditions.
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.
