A pheromone-based attract and kill formulation, LastCall™ offers a sustainable, non-polluting, effective tactic for management of forest Lepidoptera. LastCall™ very selectively removes male moths of the target species from the ecosystem with negligible impact on non-target organisms. Baits combine the selectivity of pheromone (only 0.12 g/ha, compared to 3.5-20 g/ha for mating disruption) with rapid toxicity of insecticides (only 4.5 g/ha, compared to 500-800 g/ha for conventional sprays). LastCall™ EucosmAK is now registered for control of Western Pine Shoot Borer on ponderosa and lodgepole pine.
