Abstract

fetched live from OpenAlex

Nymphs and adults of the tarnished plant bug ( Lygus lineolaris (Palisot de Beauvois)) feeding on grapevine were videorecorded in the laboratory to determine the short-term impact of feeding punctures at various phenological stages. Feeding behaviour was significantly different between nymphs and adults in the number of punctures but not in the feeding time spent. Observations by light and scanning electron microscopy showed that, from phenological stages B (bud burst) to F (visible cluster), feeding did not cause plant damage and injuries did not impact the meristems, which were coated with viscous or filamentous pectin. During phenological stages H (florets separated) and I (flowering), feeding was restricted to nectar glands, and as there is no functional relationship between nectaries and ovaries, feeding had no impact on normal development of ovaries. In later phenological stages J (berry set) to L (cluster closure, berry touch), most damage was on the pedicels of berries. Pedicels attacked at the next phenological stage show no evidence of injuries. Grapevine appears to tolerate punctual feeding made by this insect; damage is minimal and berry production is not threatened.

Teacher imitation

Not 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.
