Codling moth control by pheromone-mediated mating disruption
Lepidopteran insects use sex pheromones to communicate for mating. Olfactory communication and mate-finding can be prevented by permeating the atmosphere with synthetic pheromone.
The codling moth sex pheromone, codlemone, is species specific and nontoxic. Orchard treatments with up to 100 grams of synthetic codlemone per hectare effectively control codling moth populations over the entire growing season.
Research on codling moth was part of the Biosignal programme, 1996-2005, funded by MISTRA. After areawide tests in the Rörum orchard area, we have registered mating disruption for control of codling moth with the Swedish Chemicals Agency in 2006.
Practical implementation and registration of the mating disruption technique has been realized at an opportune time, since the most frequently used insecticide azinphosmethyl (guthion, gusathion) has been deregulated by the Swedish Chemicals Agency (linkto: www.kemi.se) in 2007, due to its acute neurotoxicity. We have accordingly provided the growers with an efficient biological control method in due time.
