Susceptibility of cranberry girdler to entomopathogenic nematodes
Bibliographic record
Abstract
The cranberry girdler, Chrysoteuchia topiaria (Zeller) (Lepidoptera: Pyralidae), is the most important sod webworm species attacking turfgrasses in Quebec, Canada (Simard 2001). Unlike other webworms, the cranberry girdler is rarely observed on grass blades but feeds on the crowns and roots in the thatch. Biopesticides based on a nematode–bacterium complex appear to hold promise as a means of controlling turfgrass insect pests, particularly those that colonize the thatch and the first few centimetres of soil (Potter 1998), such as the cranberry girdler (Georgis and Hague 1991). Our objective was to assess the susceptibility of the cranberry girdler to entomopathogenic nematodes. In the laboratory, we determined the LC 50 values for four nematode species and evaluated the effect of contact time on host mortality.

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.
