Abstract

fetched live from OpenAlex

Seeking alternative control methods against the olive psyllid, Euphyllura olivina, crude aqueous extracts of Capsicum frutescens, Melia azedarach and Peganum harmala were used on trees infested with the pest. Fifty grams of each dried plant extract/liter of water were sprayed. Trees treated with water or dimethoate were used respectively as control or standard. The population densities of the psyllid were counted 2, 6 and 14 days after treatment. The extracts significantly affected the psyllid populations. According to the observation period, the densities of the insect varied from 0 to 64, 2 to 90 and from 0 to 83 individuals/olive branch for C. frutescens, M. azedarach and for P. harmala, respectively. In the controls blocks, the psyllid densities ranged from 0 to 9 and from 32 to 101 individuals/olive branch for dimethoate and water, respectively. The results are discussed in the perspective of olive pest management.

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.
