Recently, we have explored novel approaches of achieving “high-performance” mating disruption, defined as exceeding 95 % efficacy even under high population densities and with limited inputs of companion insecticides. This work has been grounded in earlier investigations of disruption mechanisms, which suggested that competitive attraction between calling females and synthetic pheromone sources is an important component of effective and economical disruption. For Oriental fruit moth (OFM), Grapholita molesta (Busck), we have developed a mechanized applicator for high-speed deployment of pheromone dispensers made of paraffin or microcrystalline wax to tree fruit. One ha of crop can be treated in ca. 20 min. By modifying our applicator to dispense larger 0.3 g wax drops at an intended rate of 20 / tree and increasing the pheromone concentration to 10 % (by weight) in an improved wax formulation manufactured by ISCA Technologies, we achieved high-performance disruption of OFM for more than 90 days with a single application of wax in early spring. For codling moth (CM), Cydia pomonella (L.), we are investigating experimental PVC dispensers manufactured by Trece Co. intended to better protect the active ingredient, codlemone, and to co-release both codlemone and the pear ester (ethyl (E,Z)-2,4-decadienoate). Initial results suggested that co-releasing codlemone and pear ester improved mating disruption of CM over standard Isomate-C Plus dispensers during the second moth flight in mid to late summer. Furthermore, equivalent disruption was obtained with PVC dispensers loaded with 100 % codlemone and those loaded with a 10 : 90 ratio of codlemone : pear ester. During the spring generation, disruption with PVC dispensers loaded with pear ester and codlemone (60 : 40) was equivalent to that achieved with dispensers loaded with 100 % codlemone, suggesting that this new dispenser technology may enhance disruption by better protecting the pheromone from degradation, compared with other currently-available technologies, rather than by the action of the plant volatile.
