Effects of pheromone trap design, placement, and pheromone dispenser and load on male Platynota flavedana and P. idaeusalis (Lepidoptera: Tortricidae) catches in Virginia apple orchards
Environmental Entomology 18 (1), 145-149
Abstract: The Pherocon 1C trap baited with a rubber septum impregnated with 2.5 mg pheromone captured the greatest number of Platynota flavedana Clemens moths. Traps hung at 2.1 and 3.0 m captured the greatest number of P. flavedana. Trap heights of 1.2, 2.1, and 3.0 m caught the greatest number of P. idaeusalis (Walker) moths. The outside-the-canopy trap position captured more P. flavedana moths; whereas the within-canopy trap location caught the greatest number of P. idaeusalis moths. Traps placed in the west portion of the tree captured the greatest number of P. flavedana moths. P. idaeusalis moth catches were not influenced by compass quadrants.
