Effects of Exposure to Pheromone and Insecticide Constituents of an Attracticide Formulation on Reproductive Behavior of Oriental Fruit Moth (Lepidoptera: Tortricidae)
Bibliographic record
Abstract
The effect of exposure to both the pheromone and insecticide constituents of an attracticide formulation on subsequent pheromonal response of male oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae), was tested in several wind tunnel bioassays. Male response to the attracticide formulation was significantly reduced in all behavioral categories, including source contact 1 h after sublethal exposure (both by voluntary contact in the wind tunnel and forced application in the laboratory) to the attracticide formulation containing inert ingredients, pheromone, and insecticide. Sublethal exposure to the attracticide formulation in the laboratory (forced application) 24 h before the bioassay resulted in a significantly lower proportion of males subsequently responding to attracticide droplets in the wind tunnel. However, voluntary contact of male moths with the toxic formulation in the wind tunnel had no effect on subsequent response 24 h later. Exposure of males to different constituents of the attracticide formulation demonstrated that both pheromone and insecticide exerted effects on subsequent male pheromonal response. Exposure to the formulation containing the inert ingredients plus the pheromone (no insecticide) significantly reduced male behavioral responses to an attracticide droplet in the wind tunnel 1 h but not 24 h after exposure, compared with males treated with inert ingredients alone. Response to attracticide droplets was further reduced by exposure to the entire attracticide formulation containing inert ingredients, pheromone and insecticide at both 1 and 24 h postexposure. Similarly, males exposed to inert ingredients plus pheromone were less likely to orient to female-produced plumes 1 h but not 24 h after exposure than males treated with inert ingredients alone. Response to female-produced plumes was further reduced at 1 h but not at 24 h after exposure to the entire attracticide formulation. Mating success of males was significantly reduced by exposure to the entire attracticide formulation but not to the formulation without insecticide when placed with females 1 and 24 h postexposure. These findings suggest that sublethal poisoning of males exposed to the attracticide formulation will enhance the effectiveness of this formulation under field conditions.

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.
