Establishment of <i>Platygaster tuberosula</i>, an introduced parasitoid of the wheat midge, <i>Sitodiplosis mosellana</i>
Bibliographic record
Abstract
Abstract Wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae), was first detected as early as 1901 in Western Canada. The first major outbreak in Saskatchewan was recorded in 1983. In 1984, Saskatchewan wheat midge populations were found to be parasitized by the egg parasitoid Macroglenes penetrans (Kirby). Parasitism levels vary from year to year but, on average, 33% of wheat midge populations are parasitized by M. penetrans . In 1993 and 1994, Agriculture Canada and the International Institute of Biological Control in Delémont, Switzerland, collaborated to release Platygaster tuberosula Kieffer into Saskatchewan to augment biological control of wheat midge. Platygaster tuberosula individuals were recovered at low numbers in follow-up monitoring programs in each of the last 5 years. In 2001, the parasitoid population density increased fivefold at the release site and showed signs of migrating into the surrounding area.

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.
