Biological control is a prospective control method that contributes to the diminution of chemical pollution. Using the entomophagous wasp Trichogramma embriophagum Htg. The pheromone traps ATRAFUN we determined the flight curve of the pest Cydia funebrana (plum fruit moth) in order to apply control treatments. Results concerned the efficacy of the bio-preparation Trichotim used by launching during the 1st and 2nd generations of the plum fruit moth worm (Cydia funebrana) at a rate of 300,000 wasps/ha. Data show that applying the bio-preparation Trichotim in an intensive plum plantation (the cultivar Anna Späth) reduced the frequency of fruits attacked with 50% compared to the control (not treated). Yield results were evaluated after the previous use of the foliar fertiliser Nutrient Express, in which we obtained an increase in yield of 140 kg/ha compared to the control variant.
