Abstract

In this article were elaborated the methodological procedures of the system disorientation of the males from Mamestra brassicae specie. It was demonstrated that the preparative form made of natural leather is the most appropriate for applying it in the method of disorientation. It was estimated that even if apply 30 gr. of pheromone per a hectare does not lead to blockage of the sexual relations between the sexes of the abovementioned specie, despite of the density of the population on the respective area. Even though, the environment saturated with pheromone had a huge infl uence on the reduction of the density of the abovementioned specie (with approximation of 77, 0 – 100%).
