Microhabitat Location of <I>Exophthalmus jekelianus</I> (White) (Coleoptera: Curculionidae): Is There a Preference for Shade-Grown Coffee?
Bibliographic record
Abstract
Abstract The Costa Rican weevil, Exophthalmus jekelianus (White) (Coleoptera: Curculionidae), is an economically important defoliator of coffee, Coffea arabica, in the Turrialba region of Costa Rica. Preliminary observations of E. jekelianus behavior suggest a preference for shaded microhabitat, which could have important implications for E. jekelianus management. Our results support that E. jekelianus prefer shade to sun microhabitat in a controlled environment, and furthermore, that E. jekelianus location within the coffee agroecosystem is strongly influenced by both shade and the amount and type of fertilizer applied. We postulate that temperature and humidity of the microclimate surrounding a coffee plant and coffee plant nutritional quality are the key factors in determining microhabitat location for E. jekelianus. Our findings contribute to knowledge of curculionid microhabitat selection and provide novel approaches to monitoring and management of E. jekelianus on Costa Rican coffee.

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.
