Developing techniques for monitoring forest tent caterpillar populations using synthetic pheromones

Abstract: To effectively monitor forest tent caterpillar, Malacosoma disstria Hubner (Lepidoptera: Lasiocampidae), populations using sex pheromone baited traps, we field-tested pheromone dispenser (lure) type, lure age, and trap design using (Z,E)-5,7-dodecadienal:(Z,Z)-5,7-dodecadienal (100:1). Rubber septa lures, polyurethane lures, and two trap types [sticky-type pheromone traps (Wing Trap 1) and bucket-type pheromone traps (Universal Moth trap)] were evaluated. Traps baited with polyurethane lures produced higher trap catches and lower zero-catch frequencies than did rubber septa traps. There was no detectable difference in trap catch among polyurethane lures aged 0-28 days. Wing traps reached a functional saturation point in outbreak M. disstria populations and caught fewer moths than Universal traps in nonoutbreak populations. A nonsaturating trap such as the Universal trap in conjunction with the polyurethane lure should be effective for monitoring M. disstria populations.
