Abstract

fetched live from OpenAlex

Abstract Lygus keltoni Schwartz and Foottit is a species of plant bugs recently recognized as distinct from L. shulli Knight and an important component of the pest complex that attacks a number of field crops such as canola ( Brassica napus ) and alfalfa ( Medicago sativa ) in western Canada. The current laboratory study was undertaken to determine basic life-history parameters, such as instar duration, adult longevity, and reproductive potential, required to develop biologically based pest management strategies. At 25–27 °C, males lived around 34 days and females lived around 48 days. Females produced an average of 133 nymphs but up to 306 nymphs during their reproductive life, which averaged around 4 weeks (7-day preoviposition period). Egg incubation lasted around 10 days, instars 1–4 lasted 2–3 days each, and the 5th instar lasted 4 days. The reproductive potential of L. keltoni seems to be lower than that of L. hesperus Knight and L. lineolaris (Palisot de Beauvois), but other life-history parameters of the adults and development times of the nymphs are comparable.

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.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
