Technical Abstract: During the past two seasons I have tested the use of a sex pheromone-based management program for codling moth that utilizes the aerosol Paramount puffer spaced inside an orchard at a density of one unit per hectare (2.5 acres) and treating the orchard's edges with a full-rate of Isomate-C+ dispensers or the Isomate CM/LR dispenser. During 1999 we found no difference in moth catch per day in traps baited with either 1 mg or 10 mg lures in replicated 40 acre plots treated either with puffers, or a half or full rate of Isomate-C+. During the 2000 season we evaluated puffers in seventeen 40 acre orchards for either codling moth alone or for both codling moth and obliquebanded leafroller. Puffer- treated orchards were compared with similar orchards treated with Isomate-C+ and which only used insecticides to manage leafrollers. Data will be presented that clearly shows that the puffer program was as successful as Isomate-C+ for codling moth and reduce levels of leafroller-injured fruit ca. 60. Percent compared with the insecticide-only programs. A new passive, high-emission dispenser deployment program (M.B.A.) will be presented.
