ABSTRACT.
Monitoring adult codling moth, Cydia pomonella (L.), is a crucial component in implementing effective integrated management programmes in apple, Malus domestica Borkhausen. Use of sex pheromone lures to track male populations has been the traditional approach, but their use in orchards treated with sex pheromone for mating disruption (MD) has been problematic. Development of kairomone and kairomone?pheromone combination lures has allowed the catch of female moths and has benefited several aspects of codling moth management through improved spray timings and action thresholds. Recently, a new four-component volatile blend (4-K) comprised of pear ester, (E,Z)-2,4-ethyl decadienoate (PE), (E)-11 4,8-dimethyl-1,3,7-nonatriene, all isomers of pyranoid linalool oxide and acetic acid (AA) has been characterized that has increased female moth catch threefold versus any previous blend. Field trapping studies were conducted to compare moth catches in traps baited with 4-K versus the use of sex pheromone, (E,E)-8,10-dodecadien-1-ol (PH) in combination with PE and AA. Trials were conducted in orchards left either untreated, or treated with PH or PH + PE. Traps baited with 4-K and 4-K + PH lures caught significantly more females than traps baited with PH + PE + AA lures. Traps baited with 4-K + PH lures caught significantly more total moths than traps baited with PH + PE + AA lures in all three orchards. Adding a PH lure to traps with the 4-K lure did not affect female catch, but significantly increased male and total moth catches. These studies demonstrate that codling moth can be trapped effectively in apple under MD without the use of sex pheromone lures. The significant increase in female codling moth catch with the 4-K lure suggests that efforts to improve spray timings and action threshold determinations as well as mass trapping might be enhanced with this new lure. © 2019 Blackwell Verlag GmbH
