The practice of mating disruption replaces a single point source used for monitoring, with broadcast or blanket placement of pheromone throughout a field. The broad scale emission of pheromone masks over a female point source, habituates the males, or otherwise delays or prevents mating, thereby preventing the damaging stage (immatures) of many insect pests.
: In 2002-2003 Dr. Sridhar Polavarapu demonstrated that Oriental beetle mating could be prevented by mating disruption practices. In subsequent years we are trying to reduce pheromone rates in order to make the practice affordable for growers and cost competitive with insecticides.
In 2005 plots were 1 ha each (2.47 ac), with 4 treatments of 1) Low - .1g ai/dispenser with 20 dispensers per acre (2g ai/acre), 2) Medium - .1g ai/dispenser with 40 dispensers per acre (4g ai/acre), 3) High - .5g ai/dispenser with 20 dispensers per acre (10g ai/acre), and 4) untreated control. Plots were replicated 3 times in a randomized complete block design, including untreated buffer rows of at least 200’ between treatments, and 500’between blocks. Dispensers were attached to an outside blueberry cane, within the row orientation, with a wire twist tie, about 20 cm above the soil surface. The adult flight was monitored with Japanese beetle can traps (Great Lakes IPM, Vestaburg, MI), baited with 300μg of (Z)-7-tetradecon-2-one lures, placed 3 traps per plot to monitor trap shutdown. Traps were placed on wire hangers so the bottom of the can was just off ground level. Traps were placed in plots on 6/6 with pre-treatment counts taken on 6/13 and 6/16. Pheromone dispensers were placed in plots on 6/16 just after traps were monitored. Traps were monitored once per week until 8/25, and lures were changed on 7/15. Trap shutdown is the first measure of successful mating disruption, since it mimics the failure of males finding unmated females. Traps
