The scope of the research was to determine the biological efficiency of the multicomponent blend of Orienthal fruit moth sex pheromone in the apple orchard. The introduction of the minor component M1 in doses of 10% to the basic components on dispensers had led to a increase in number of males caught in sex pheromone traps by 1,7 times. While the male captures on traps where was added 10% of minor component M2 to the basic ones had led to a increase by 1,2 times. The minor component M2 in-crease of doses had led to a proportional decrease of the male caught in traps. Research will be continued.
