Researches Regarding the Use of Mating Disruption Pheromones in Control of Apple Codling Moth - Cydia pomonella L

The climatic changes of the latest years led to obvious changes in the biological cycle of the many orchard pests. In the case of the apple codling moth - Cydia pomonella L., one of the most damaging pest of the apple orchards, under our Country conditions it can develops also the third generation, the adults flight extent became wider, the attack of the second generation of larva is more aggressive and under some particular orchard conditions resistance to various groups of insecticides were noticed. The work presents the results obtained during 2013-2014 at Research Institute for Fruit Growing Pitesti Romania, using matting disruption method. ISOMATE C pheromone dispensers (E,E-8,10-dodecadiene-1-ol 52.4%, 1-dodecanol 30.6%,1tetradecanol 7.1%) combined with a reduced number of treatments with insecticides were used to control apple codling moth. The percentage of the attacked fruits in the plot where pheromone dispensers were applied was 0.3-0.4% (in 2013) and 0.08-0.011% (in 2014). The results obtained during the study revealed that matting disruption is an efficient alternative method to control apple codling moth - Cydia pomonella L., which contribute to environment protection and cleaner high quality fruits production.
