Host Age and Parasitism by <I>Tiphodytes gerriphagus</I> (Hymenoptera: Scelionidae), an Egg Parasitoid of Water striders (Heteroptera: Gerridae)
Bibliographic record
Abstract
Abstract Larvae of Tiphodytes gerriphagus Marchal, a parasitoid of water strider eggs, are able to develop within Limnoporus dissortis Drake & Harris eggs that have undergone >80% of their embryological development. In laboratory studies, parasitoid development time was unaffected when young and intermediate aged eggs were attacked, but increased when old host eggs (6 to 8 d) were used. Likewise, wasp body size did not change significantly except for the oldest host eggs, from which significantly smaller wasps emerged. Old egg batches produced higher sex ratios (more males) than young eggs. This resulted from a disproportionate reduction in female eggs laid in the context of a marked overall reduction in parasitoid oviposition. Ability to parasitize over a wide range of host ages likely contributes to the high rates of parasitism observed in the field.

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.
