Lethal and Parasitism Effects of Fipronil on Trichogramma chilonis (Ishii) (Hymenoptera: Trichogrammatidae)
Bibliographic record
Abstract
The effects of lower doses including 0.4x, 0.2x, 0.08x, 0.04x, and 0.02x field recommended dose (x) of insecticide fipronil on the emergence of Trichogramma chilonis (Ishii) from the treated larval, and pupal stage of parasitoid within the host eggs of Sitotroga cerealella Olivier , and parasitism of the females T. chilonis were assessed under laboratory conditions. Both 0.4x and 0.2x doses of fipronil led to complete failure of emergence, while the remaining three doses demonstrated ≤ 25.61% emergence in the larval treatment. However, pupal treatment indicated comparatively less toxicity to the parasitoids, i.e., the 0.4x dose showed 3.40%, while both 0.2x and 0.08% doses revealed emergence 29.05, and 39.65%, respectively. Both the lower most doses including 0.04x and 0.02x showed emergence 61.81 and 73.51%, respectively. Fipronil also affected parasitism of the previously treated host eggs of Sitotroga cerealella Olivier, and led to increase in parasitism capacity when dose shifted from high rate toward lower rate: all the used doses demonstrated mean parasitism ranging from 5 to 10.7 except 0.4x dose.

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.
