The chemical ecology of the Pacific beetle cockroach, Diploptera punctata
Bibliographic record
Abstract
The cockroach, Diploptera punctata, has a wide geographic distribution throughout much of Asia and Hawaii, and as is one of the few vivaparous insect species know, it has been extensively studied by to gain insight into the underlying physiology of this unusual form of reproduction. However, there is not a great deal known about the mating behaviour of this species. We will present results, using populations from Hawaii and Thailand, showing that (i) there is very little interbreeding between the two populations, (ii) short distance pheromones are involved in mating, (iii) there are marked intersexual and inter-race differences in the cuticular profiles (iv) cuticular profiles change with age, and that in a Y tube olfactometer males respond preferentially to 5-day-old virgins over air but do not discriminate between air and newly - emerged virgins. The last observation was interesting, given that in the literature it has been reported that ma ting occurs just after the female has moulted, before her cuticle has even hardened. Furthermore, while newly - mated females show no overt courtship behaviour, older individuals do, including strong rejection behaviours when courted. We postulated that the idea that females normally mate immediately after emergence is an artefact of the rather simple cages used in laboratory rearings. We found that mating success declined as the complexity of the environment was increased, suggesting that in nature a female may hide during moulting and only mate once her cuticle has hardened.

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.
