Endoparasitoid Assemblage of the Pea Leafminer,<i>Liriomyza huidobrensis</i>(Diptera: Agromyzidae), in Southern Ontario
Bibliographic record
Abstract
The pea leafminer, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae), is an important pest of leafy greens in the Holland Marsh, Bradford, Ontario, and was first discovered in this area in 1998. A 2-yr study was undertaken to document the parasitoid complex of this recent addition to leafminer guild in Ontario and examine endoparasitoids reared from pea leafminer pupae collected from eight host plants: celery (Apium graveolens L.), spinach (Spinacia oleracea L.), lettuce (Lactuca sativa L.), mustard greens (Brassica juncea L.), pea (Pisum sativum L.), potato (Solanum tuberosum L.), and gai lan (Brassica alboglabra L.). Members of three families of Hymenopteran parasitoids were identified: Chrysocharis oscinidis Ashmead (Eulophidae), Halticoptera circulus (Walker) (Pteromalidae), and three species in the Braconidae, including two unidentified Dacnusa spp. and one unidentified Opius sp. Mortality and parasitism rates of pea leafminer pupae were higher in 2002 than 2003 and varied according to host plant. Parasitism rates ranged from 4 to 27% in 2002 and 4% to 13% in 2003. The parasitoid complex differed among host plants, and there were differences in the range of host plants on which parasitoids were found to parasitize pea leafminers.

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.
