Abstract
Abstract Natural enemies of herbivores function in a multitrophic context, and their performance is directly or indirectly influenced by herbivores and their host plants. Very little is known about tritrophic interactions between host plants, pests and their parasitoids, particularly when the host plants are under any stress. Herbivores and their natural enemies’ response to plants under stress are diverse and variable. Therefore, in this study we investigated how diamondback moth, P lutella xylostella ( L .), reared on water‐stressed host plants ( B rassica napus L . and S inapis alba L .) influenced the development of its larval parasitoid, D iadegma insulare ( C resson). No significant differences were observed in development of P . xylostella when reared on water‐stressed host plants. However, all results indicated that water stress had a strong effect on developmental parameters of D . insulare . Development of D . insulare was delayed when the parasitoid fed on P . xylostella , reared on stressed host plants. Egg to adult development of D . insulare was faster on non‐stressed B . napus than non‐stressed S . alba followed by stressed B . napus and S . alba . Female parasitoids were heavier on non‐stressed host plants than stressed counterparts. Furthermore, the parasitoid lived significantly longer on stressed B . napus . However, body size was not affected by water treatment. Most host plant parameters measured were significantly lower for water‐stressed than non‐stressed treatments. Results suggest that development of this important and effective P . xylostella parasitoid was influenced by both water stress and host plant species.

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.
