Abstract

Apple moth (Cydia pomonella (Linnaeus, 1758)) (Lepidoptera: Tortricidae) is the most important apple pest in all apple growing areas, including the Republic of Croatia. It regularly causes economically significant damages to the fruits. It has two generations per year, and when the conditions are completed even third generation appears. For effective control, it requires a greater number of chemical treatments if other protection methods are not used (e.g. confusion method). In recent years there is a noticeable damage increase in the Mediterranean part of Croatia relative to the Continental part. The simplest and most effective method for monitoring moth flight is by using pheromone traps. Based on captures, it is possible to prepare Protection programs and enforce fruit protection using a biofix model. The capture of the first moth (butterfly) as a method of synchronization of the model and physiology of field populations is the basis of biofix model. The purpose of the research was to determine the efficacy of the recommended Protection program by combining plant protection products in two climatic regions of the Republic of Croatia, containing active substances in the order of: phenoxycarb, chlorantraniliprol + abamectin, emamectin benzoate. During 2018 monitoring of the population dynamics and damage to the fruits identified the occurrence and the number of moths in one locality in the Continental and one locality in the Mediterranean part of the Republic of Croatia, the damages caused by its caterpillar as well as the efficacy of the recommended protection programs. Recommendations for the positioning of the products within the recommended protection programs have been established and pesticide residues in the fruits have been determined. Damages to apple fruits are higher in Mediterranean growing area and it is necessary to increase the number of treatments compared to the Continent part.
