Responses of rubidium-labeled and unlabeled male Grapholita molesta (Lepidoptera: Tortricidae) to pheromone sources

Male oriental fruit moths reared on diet enriched with rubidium (6000 ppm), or on diet without (0 ppm) were flown in a wind tunnel and scored for their exhibition of a series of expected behaviors leading to contact of pheromone source (i.e., pheromone lures) upwind of their relase point. Moths 2-5 days past pupal eclosion were used. The moths were observed for 5 behaviors: wing-fanning; take-off; lock-on; upwind flight; and source contact. The data were analyzed by way of logistic regression.
