Field and laboratory studies on the effects of host fruit volatiles on «Rhagoletis mendax» (Diptera: Tephritidae) adults
Bibliographic record
Abstract
I examined olfactory responses of the blueberry maggot fly Rhagoletis mendax Curran towards organic volatile compounds extracted from host fruit, in both field and laboratory experiments. First, I investigated the effects of eight volatile treatments on the capture rate of adult flies, in Saint-Chrysostome, QC. A second study focused on testing the attractiveness of the same volatile treatments in wind tunnel bioassays. I also evaluated the effect of experience, sex and population on the olfactory response of these flies. Ammonium acetate was one of the more effective lures in field experiments during the early season. The treatment blend of terpenes and alcohols had the highest fly capture rate in early and late season but it did not differ significantly from ammonium acetate. Ammonium acetate elicited the strongest response in wind tunnel bioassays, followed by a blend of aldehydes and alcohols. Nova Scotia flies had an overall higher response to treatments than the Quebec population and male flies exhibited a higher flight frequency. Experienced flies were also less stimulated by the treatments than naive flies. This research has provided an initial step in identification of attractive host fruit volatiles to R. mendax adults, supporting the hypothesis that volatile host blends of specific compounds are attractive to the insect. It is also suggested that future experiments use either male or female, naive flies from the same geographical location.

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.
