Technical Abstract: Laboratory experiments were conducted to generate basic information about the volatility of oriental beetle, Anomala orientalis Waterhouse, synthetic mating pheromone, (Z) and (E)-7-tetradecen-2-one, in order to develop wax-based granule formulations to disrupt mating of this pest infesting turfgrass. Rubber septa are used to bait traps to evaluate treatments in field experiments; therefore, septa impregnated with pheromone were evaluated as well. Rubber septa loaded with 10, 100, and 300 micrograms/septa provided steady rates of pheromone release (zero-order) over 4 weeks of evaluation (total = 1.1, 9.0, and 26.9 micrograms/4 weeks, respectively). Septa with 1,000 micrograms/septa had a significant decline in the rate of pheromone release for this 4-week exposure time (total = 119 micrograms/4 weeks). A proprietary wax granule (25% w/w pheromone in granules weighing 0.044 gram/granule provided steady rate of pheromone release (total = 2347 micrograms/4 weeks/granule) that exceeded the rate of rubber septa. Experimental granules were made by dripping molten soywax and pheromone solutions into a pan granulator of excess perlite. Experimental granules (0.016 gram/granule made of soywax with higher pheromone loads (10% w/w) approached zero-order release (steady state) (total = 69 micrograms/4 weeks/granule) while smaller granules (0.004 gram/granule with less pheromone (0.1% w/w) provided first-order release profiles (decreasing rate with longer exposure time) (total = 0.35 micrograms/4 weeks/granule). A field trial demonstrated the potential of granular formulations to provide effective mating disruption as measured by trap shutdown for up to 4 weeks where turfgrass was treated. Documenting pheromone release profiles for these experimental granules and rubber septa provides valuable information that will support future field evaluations of mating disruption as a control strategy.
