Feeding impact of <i>Lygus lineolaris</i> (Heteroptera: Miridae) on <i>Vitis vinifera</i>: a behavioural and histological study
Bibliographic record
Abstract
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.

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.
