Semiochemical-based mass trapping of the apple clearwing moth (Synanthedon myopaeformis (Borkhausen)) (Lepidoptera: Sesiidae)

  • Semiochemical-based mass trapping was tested against the apple clearwing moth (Synanthedon myopaeformis (Borkhausen)), an invasive apple pest in British Columbia. Two yellow traps baited with apple clearwing moth sex pheromone, (Z,Z)-3,13 octadecadienyl acetate, and Concord grape juice, respectively were tested. Mass trapping reduced moth capture in assessment traps more reliably with pheromone than juice mass traps. The optimal trap density was 50 – 100 traps / ha for pheromone and at least 100 traps / ha for juice traps. The main effect of pheromone-based mass trapping was disruption of male moth orientation. Moth catches and mating status of captured females in juice assessment traps in plots treated with pheromone mass traps did not differ from the control. Catches in the two trap types were correlated and juice traps can monitor moth flight. Traps targeting the apple clearwing moth captured non-target arthropods that were more diverse in organic than in conventionally-managed orchards.
