Potential effect of<i>Beauveria bassiana</i>(Hypocreales: Clavicipitaceae) on<i>Anthonomus signatus</i>(Coleoptera: Curculionidae) in strawberries
Bibliographic record
Abstract
The strawberry bud weevil, Anthonomus signatus (Say) (Coleoptera: Curculionidae) is a serious pest of strawberry crops in Canada. The results of previous laboratory screening and bioassay experiments showed that A. signatus adults were susceptible to several isolates of Beauveria bassiana (Balsmo) Vuillemin. Based on these results, the INRS-IP and INRS-CFL isolates were selected for field trails. Using a randomized block design with four replicates, three applications of the INRS-IP and INRS-CFL isolates were applied at a rate of 1×1013 conidia/ha at 7-day intervals. The multiple applications of B. bassiana triggered a significant reduction of A. signatus adult populations in strawberries. Twenty-four days after the first application, a significant difference was observed between the mean numbers of surviving adults in all B. bassiana-treated plots compared to control plots. During the field experiment, the persistence of insecticidal activity and the viability of B. bassiana conidia were also monitored. Results showed the presence of viable and infective conidia on strawberry foliage up to 6 days after each application. Moreover, the multiple applications of B. bassiana at a rate of 1×1013 conidia/ha resulted in a significant reduction of damaged strawberry fruits compared with control plots, where fruit loss was caused by A. signatus feeding and egg laying.

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.
