Life History and Chemical Ecology of Xenos peckii (Strepsitera, Xenidae)
Bibliographic record
Abstract
I investigated life history traits and pheromonal communication of Xenos peckii, a parasitoid of the paper wasp Polistes fuscatus.To emerge, males cut the puparium with their mandibles, and then push aside the pupal cap with their head.The endoparasitic females engage in active calling (pheromone release) behaviour assuming a particular body posture.Seasonal and diel emergence periods of males coincide with seasonal and diel calling periods of females.Mate-seeking males land on the anterior portion of the host wasp's abdomen, and then step backward until their mesothoracic legs contact the female's cephalothorax, upon which the male initiates copulation.Analyzing pheromone gland extracts by gas chromatographic-electroantennographic detection revealed a candidate pheromone component (CPC) that consistently elicited responses from male antennae.CPC was identified as (7E,11E)-3,5,9,11-tetramethyltridecadienal based on mass and NMR spectra, and the synthesis of an authentic standard.In field experiments, traps baited with synthetic CPC captured X. peckii males.
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.
