In the climatic conditions of the year 2019, adults from generation 1 were captured in June, decades 1 and 2. The pheromonal variant V1 V1 - D (dipropyl disulfide) captured a greater number of adults, 57, 1%, compared to the control V2 - E (2 ø ethanol). - 42.9% of the total captured. Comparative study of the experiments carried out, setting up, experiments and testing of variants.
