Development of Soybean Aphid (Homoptera: Aphididae) on Its Primary Overwintering Host, <I>Rhamnus cathartica</I>
Bibliographic record
Abstract
Thermally dependent development of soybean aphid (Aphis glycines Matsumura) and common buckthorn (Rhamnus cathartica L.) were examined in growth chambers in spring 2005. Models based on ambient air temperatures for all development events were developed. Adjusted models were developed to account for heat units acquired because of solar radiation. These models were tested at field sites in Guelph and Ridgetown, Ontario, Canada. It was found that egg hatch of aphids and bud swell of buckthorn coincided at low temperatures in growth chambers and in the field. Development thresholds of 9 and 10 degrees C were acquired for bud swell and egg hatch, respectively. Models based on ambient air temperatures were poor predictors of bud swell and egg hatch in the field, but models adjusted for solar radiation predicted these events just 1-4 d before they were observed at both sites. The results obtained have broad application for predicting aphid hatch on a regional basis.
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.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
