Population dynamics of Phyllocnistis citrella Stainton, 1856 (Lepidoptera, Gracillariidae) and impact of its parasitism on clementine trees at the Boufarik-Blida station (Algeria)
Bibliographic record
Abstract
A study was conducted for eight months in 2021 in the Boufarik-Blida region (Algeria) to analyse the population dynamics of Phyllocnistis citrella and the incidence of the parasite on citrus fruit, in particular clementines. The main data showed a significant increase in the rate of parasitism, with peaks of 73% and 72% during the first outing. After 28 June, fluctuations in the rate of parasitism were observed, highlighting the importance of the activity of beneficials, particularly those reared in a greenhouse close to the orchards, such as Semielacher pesiolatus. The relationship between rates of infestation and parasitism is increasing, with parasitism exceeding infestation. This dynamic is influenced by several factors, including temperature variations, and highlights the effectiveness of biological control using parasitoids. The installation of greenhouses for rearing beneficials near infested orchards, combined with other integrated pest management methods, represents a promising and sustainable solution for combating citrus leafminer.

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.
