Abstract
A full-season mating disruption trial was conducted in 5­10-acre plots on three farms, to assess
the efficacy of three different multi-species pheromone products against codling moth, oriental
fruit moth, and lesser appleworm: Isomate CM/OFM TT ties; Checkmate CM-OFM Duel
membranes; and Suterra CM/OFM Puffers. Pheromone treatments were used as a complement
to the growers' normal insecticide programs. All three dispenser technologies suppressed adult
catches of oriental fruit moth and lesser appleworm to near-zero levels for the entire season, but
at two of the sites, some or all of the treatments allowed some breakthrough of codling moths in
late June. Placement of the CM traps in the tops of the tree canopies could have been a factor in
this finding. Weekly on-tree fruit inspections detected very few damaged fruits until mid-August.
Total fruit damage at harvest ranged from 0­7% across all sites and pheromone treatments
(compared with 1­8.4% in the nondisrupted grower standards). The Duel plot had lower total
damage than the nondisrupted plot at all three sites, as did the Isomate plot at one site. At one
site, both of these treatments had lower total damage than in the Puffer plot.
