The host specificity of the candidate biological control agent Diadromus collaris (Gravenhorst) (Hymenoptera: Ichneumonidae)
Bibliographic record
Abstract
Diadromus collaris (Gravenhorst) (Hymenoptera: Ichneumonidae), a solitary pupal endoparasitoid of Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae), is a candidate for introduction into Canada as a biological control agent. It is important to assess the parasitoid's host specificity before its release. To maximize the wasp's expressed host range, I tested five variables to determine which experimental conditions would motivate D. collaris to oviposit. Of these variables, wasp diet, exposure length, and the presence or absence of diamondback moth cocoons resulted in statistically significant differences in D. collaris emergence or diamondback moth mortality. To determine the parasitoid's fundamental host range, I exposed pupae from eight species of non-target Lepidoptera to female D. collaris in a series of no-choice tests. Three species, Plutella armoraciae, Plutella porrectella, and Acrolepiopsis assectella, were suitable hosts for D. collaris development. The results from this study provide insight into the suitability of the parasitoid for introduction into Canada.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
