Multiple species mating disruption of leafrollers in cherries in Central Otago

Mating disruption for leafrollers has been conducted on a commercial scale using a single multi-species pheromone dispenser on contiguous blocks of cherries in Central Otago for 4 years. Pheromone trap and packhouse results were collected from isolated untreated (65.4 ha) and pheromone-treated cherry orchard areas (76.4 ha) in the Cromwell district. In untreated cherry orchards, catches of light brown apple moth (Epiphyas postvittana) were exceptionally high (3.8 males/trap/day), with lower catches of Planotortrix octo (0.25 males/ trap/day). Catches of both species were strongly disrupted in the treated areas, reducing E. postvittana to 0.0036 moths/trap/day and P. octo to nil. Trap catches of both species have increased steadily over 5 years (2008/09 to 20012/13) in blocks not using mating disruption. Packhouse results showed that all of the fruit inspected from both treated and untreated areas were free of leafroller infestations in 2012/13. Insecticide use in the pheromone-treated areas was reduced by one application, compared with the areas without pheromone.
