RECENT RANGE EXPANSIONS OF PERISTENUS DIGONEUTIS (HYMENOPTERA: BRACONIDAE), A PARASITE OF THE TARNISHED PLANT BUG (HEMIPTERA: MIRIDAE), AND HIGH TEMPERATURES LIMITING ITS GEOGRAPHIC DISTRIBUTION IN NORTH AMERICA
Bibliographic record
Abstract
Peristenus digoneutis was discovered in one new state (Maine) and in 15 new counties in Maine, New Hampshire, New York, Pennsylvania, and Vermont during 1997–1999. These new records increased the number of counties where this parasite has been found by 42%, to a total of 51 counties in eight states. No permanent establishments of P. digoneutis have been found south of New York City, which suggests that high summer temperatures are limiting its spread southward. A good agreement was found between the parasite's southernmost establishment locations and a maximum summer temperature/duration of 30°C (86°F) for 14 to 30 days. This temperature limit suggests that P. digoneutis can disperse westward both north and south of Lake Erie, across southern Ontario and northern Ohio, to Michigan and Wisconsin. Establishment south of New York City (latitude 40.5°N) is unlikely, except possibly along the higher/cooler elevations of the Appalachian Mountains.
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.
