Sažetak
In recent times, high populations of codling moth (Cydia pomonella) have been observed in Croatian apple orchards. The appearance of large populations of this pest is in accordance with data from other parts of Europe and the world. In the last ten years in orchards in which monitoring of codling moth by pheromone traps is conducted increasing daily moth catches and earlier appearance of the pest have been observed. More than ten years ago codling moth was caught to the end of July. Today adult flight lasts until the end of September. The number of treatments against codling moth has increased seven times. Reasons for the increased number of treatment are complex ; global warming, resistant strains of codling moth, a third generation of the pests. Monitoring the appearance of the first generation of adults and efficient temperature sums in field conditions indicate the emergence of pests with a lower temperatrure requirement. the exteded flight of adults to September and the dynamics of adult catches on pheromone traps indicate the presence of a third generation of the pest. Integrated protection measures against codling moth are encountering a series of problems. Environmentally more favourable measures of protection against codling moth, like the mating disruption technique, which ia applied in Western Europe has not shown satisfactory results in Croatia because of the small size of orchards. Biological products such as those based on the virus are not available on the Croatian market. The number of insecticides registered for codling moth control is small, with only a few active substances, which will lead to a greater number of applications per year and increase the rate of development of resistant strains of the pest.
