Morphology of the Pre-Imaginal Life Stages of the Cabbage Seedpod Weevil, Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae)
Bibliographic record
Abstract
The cabbage seedpod weevil is a serious pest of canola or oilseed rape (Brassica napus L.) and several other brassicaceous seed crops in both Europe and North America. A number of Ceutorhynchinae species can occur in canola or in cruciferous weeds infesting the crop, but immature stages of few of the species are well described. The morphology of pre-imaginal life stages of the cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham), is presented. Descriptions are given of taxonomic characters observed under both phase contrast and scanning electron microscopy. Characters to separate C. obstrictus and its sympatric congener Ceutorhynchus neglectus Blatchley include the numbers of dorsal, ventral, and lateral epicranial setae and the numbers of setae on the labrum, maxillary palps, stipes, and mala.
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.
