Seasonal Abundance, Parity, and Survival of Adult <I>Culicoides sonorensis</I> (Diptera: Ceratopogonidae) in Southern Alberta, Canada
Bibliographic record
Abstract
Culicoides sonorensis (Wirth & Jones) (Diptera: Ceratopogonidae) adults were active from May through October during 2002-2006 in southern Alberta, Canada. Adults were first captured in May, and populations peaked in early June, late July, and late August. The first population peak occurred when mean weekly temperatures exceeded 16 degrees C, resulting in a variable amount of time for spring emergence. This asynchrony in spring emergence accounted for much of the annual variation in timing of subsequent population peaks. Peaks were separated by an average of 6-7 wk. C. sonorensis seems to have one overwintering generation and two generations during the summer. Abundance was correlated among sites located up to 90 km apart. Abundance at a rangeland site increased more rapidly with mean weekly temperatures than at feedlot sites. The proportion female ranged from 0.68 to 0.83 but showed no consistent differences between rangeland and feedlot sites. The proportion female declined with distance from a developmental area at the rangeland site. Proportion parous was similar among rangeland and feedlot sites, and it also declined with distance from a developmental area at the rangeland site. The proportion parous increased early in the season, fluctuated throughout the mid-season, and increased with cooler temperatures in the fall. The proportion parous tended to increase when temperatures decreased. Estimates of adult daily survival were generally >0.8. Survival declined with temperature, was lowest in midsummer, and increased during the fall.

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.
