Intra- and Inter-Specific Variations on the Chorionic Ultrastructures of <I>Delia</I> Eggs (Diptera: Anthomyiidae)
Bibliographic record
Abstract
Three Nearctic and six Palearctic populations of Delia radicum L., two Palearctic populations of D. antiqua Meigen, and one Palearctic population of D. floralis Fallen were used to evaluate the range of intraspecific variation in the chorionic ultrastructures of the egg of D. radium, and to compare the chorionic ultrastructures of these eggs with those of the two other species. High variability in the mean size of the egg and hatching slit were found among populations of D. radicum. The D. radicum populations observed were not homogenous for quantitative variables but the qualitative variables showed less variability. Two patterns of antimicropylar poles were observed for D. radicum: the Random and Flower patterns. These two patterns were observed in all Nearctic populations and, among the Palearctic populations, only in the French and the English populations. The other Palearctic populations had only the Random or the Flower pattern. These results support the hypothesis that the North American populations originated from north–western Europe. Our results demonstrate that the three species, D. radicum, D. floralis (Fallen), and D. antiqua (Meigen), have specific chorion, micropyle, and antimicropyle patterns. The eggshell of D. radicum is more similar to that of D. floralis than that of D. antiqua.

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.
