Facultative hyperparasitism by the potential biological control agent Aptesis nigrocincta (Hymenoptera: Ichneumonidae)
Bibliographic record
Abstract
This study investigated whether Lathrolestes ensator, a parasitoid released as a biological control agent against the European apple sawfly in Canada, is successfully attacked by the cocoon parasitoid A.nigrocincta. In a no-choice situation in the laboratory, there was no significant difference between the acceptance of unparasitized hosts and hosts containing an egg of L. ensator by females of A.nigrocincta. In addition, A.nigrocincta attacked mature larvae of the larval parasitoid to the same degree as they attacked unparasitized hosts. Survival of A.nigrocincta offspring was close to 100% regardless of whether they developed in unparasitized hosts, in hosts containing an egg of L. ensator or in host cocoons containing mature larvae of L.ensator. This is discussed in the context of the possibility of releasing A.nigrocincta as an additional biological control agent of the European apple sawfly.
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.

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.
