Female‐biased sex ratio shifts in a solitary parasitoid and their effects on virginity, population dynamics, and biological control
Bibliographic record
Abstract
Abstract Mated female parasitic wasps can control the sex of their offspring by controlling which eggs are exposed to sperm. Females that have failed to mate, however, are restricted to producing only male offspring, as all their eggs are unfertilized. We incorporated the effects of these sometimes constrained, sometimes flexible parasitoid sex ratios into a basic N icholson– B ailey population model. We found that the less common case of an increasing female bias in response to competition can destabilize dynamics and have both positive and negative effects on host suppression. We also incorporated the effects of virginity due to a lack of males into the model. Virginity had stabilizing effects on parasitoid‐host population dynamics, and prevented runaway female bias in a parasitoid population. We found that the changes in host suppression caused by these new behaviours can be either positive or negative, and are highly dependent on the search efficiency of the parasitoid.

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.
