Overwintering survival of bagworms,<i>Thyridopteryx ephemeraeformis</i>(Lepidoptera: Psychidae): influence of temperature and egg cluster weight
Bibliographic record
Abstract
Abstract The present study relates the survival rate of bagworm eggs to extreme winter temperature and weight of egg clutches. The eggs were collected in the spring of 2009 at 104 locations in the mid-western United States of America across a latitudinal range from 36.5–41.5 °N. Egg survival after a 1-week incubation period was overdispersed, suggesting that survival of individual eggs within a clutch is highly correlated. Logistic regression analysis revealed that the survival of eggs, assessed after 1 or 12 weeks of incubation, significantly increases with the weight of egg clutches and increasing minimum winter temperature (expressed as the maximum temperature during the coldest day of winter). Lethal temperature for 50% of egg clusters was −14 °C for clusters weighing 0.1 g and −18.1 °C for 0.4 g clusters. The regression model developed here provides a tool to forecast the persistence of bagworm populations in recently colonised locations in Michigan, United States of America and southern Ontario, Canada.

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.
