Screening of <i>Beauveria bassiana</i> (Hyphomycetes) isolates against <i>Choristoneura rosaceana</i> (Lepidoptera: Tortricidae)
Bibliographic record
Abstract
Abstract Twenty-three isolates of Beauveria bassiana (Balsamo) Vuillemin from different hosts and geographical origins were evaluated under laboratory conditions for various aspects of virulence against 2- to 3-d-old third instars of the obliquebanded leafroller, Choristoneura rosaceana (Harris), a pest of apple, Malus domestica Borkhausen (Rosaceae), and several other orchard crops in North America. When submerged in a solution containing 107 conidia/mL, all B. bassiana isolates caused more than 66% larval and pupal mortality 60 d following treatment. Isolates 14, 16, 1525, 2727, and 2990 caused the highest (80–89%) larval and pupal mortality against C. rosaceana. Relative to the control, isolate 63 significantly increased and isolate 44860 significantly decreased larval development time. Isolates 37, 2727, and 2990 significantly decreased C. rosaceana pupal weight. Isolates 139, 2727, and 2990 significantly decreased the number of emerging females. In view of their larvicidal effects, as well as their carry-over effects on pupae and adult females, isolates 2727 and 2990 showed the best mycoinsecticidal potential against C. rosaceana.

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.
