Abstract:		"Aerosol mating disruption is used for management of navel orangeworm, Amyelois transitella (Walker) (Lepidoptera: Pyralidae), in an increasing portion of California almonds and pistachios. This formulation suppresses pheromone monitoring traps far beyond the treatment block, potentially complicating monitoring and management of this key pest. Phenyl propionate is an attractant used to capture adults in the presence of mating disruption, completely suppressing pheromone traps, and lures combining phenyl propionate with a pheromone lure (PPO-combo lure) synergize trap capture in the presence of mating disruption. In this study, laboratory and field trials of different phenyl propionate dispensers indicate a useful life of six weeks. Controlled experiments found similar numbers of adults captured in phenyl propionate and PPO-combo lures in the presence of varying levels of mating disruption intensity. A subsequent trial compared monitoring of field plots at various distances from fields under commercial mating disruption for much of the growing season with pheromone and PPO-combo lures. Although there was some evidence of partial suppression of capture in PPO-combo traps closer to mating disruption compared with lures farther away, there was no failure of detection as occurred with pheromone lures. The ratio of adults in pheromone and PPO-combo traps varied with proximity from treated fields. These results indicate that, in addition to monitoring in mating disruption plots, phenyl propionate lures can be useful for insuring against failure of detection of navel orangeworm pressure in areas where mating disruption is widely used"
