Dispersal propensity of adult Colorado potato beetles (Coleoptera:Chrysomelidae) on potato and its implications on the insect resistance management plan
Bibliographic record
Abstract
A three-year (1998-2000) field and laboratory study conducted in Fredericton, New Brunswick, Canada analyzed and quantified the dispersal of adult Colorado potato beetles within and between conventional and transgenic potato plots established according to the high-dose/refuge strategy. More specifically, the study addressed the following four predictions: (1) Adult Colorado potato beetle abundance or flight activity in transgenic potato fields is positively correlated to the abundance or flight activity in the immediately adjacent refuge field. (2) Colorado potato beetle intraspecific competition on potato plants will increase the flight take-off frequency of adult CPB; tolerating relatively high numbers of CPB egg masses or larvae or a high level of CPB defoliation on potato plants in the refuge could therefore be considered to increase the movement of beetles from the refuge to the transgenic field. (3) CPB flight take-off frequency will be higher on potato plants at the bloom than at the vegetative stage; planting of the non transgenic potato crop in the refuge earlier than the Bt transgenic potato crop in the main field could therefore be considered to increase movement of the Colorado potato beetles from the refuge to the transgenic field. (4) The aggregated distribution of CPB populations in the potato crop is caused by the presence of mating pairs; strategies changing the distribution of males and females in the refuge field could therefore be considered to increase dispersal from the refuge to the main crop field.

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.
