Prevalence of four species of egg parasitoids attacking tabanid eggs in Manitoba, Canada
Bibliographic record
Abstract
Abstract Egg masses of the horse fly, Hybomitra nitidifrons nuda (McDunnough), and the deer fly, Chrysops aestuans Wulp (Diptera: Tabanidae), were collected during the summers of 1996–2000 from five different locations in southern Manitoba. On average, hymenopterous egg parasitoids were reared from more than 90% of collected egg masses. Telenomus hybomitrae Iranpour and Galloway and (or) Telenomus utilis Iranpour and Galloway (Hymenoptera: Platygastridae: Telenominae) emerged from multilayered egg masses of H. n. nuda. However, Trichogramma semblidis (Aurivillius) (Hymenoptera: Trichogrammatidae) and (or) Telenomus chrysopsis Iranpour and Galloway were reared from single-layered egg masses of C. aestuans. In H. n. nuda egg masses, more than 33% of individual eggs were parasitized and more than an additional 35% were apparently damaged by the two telenomine parasitoids. In C. aestuans egg masses, approximately 40% of individual eggs were parasitized and 18% produced neither parasitoids nor larvae.

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.
