First report to the fruit fly management in vine on Cafayate-Salta
Abstract
In the present work it was proposed to evaluate the use of massive trapping for the control of the fruit fly complex that attacks the vine, using two types of food attractants; as well as determine the species and sex captured by them, and the level of crop damage. The adaptive research work was carried out in Tolombón- Cafayate- Salta- Argentina, during the 2015/2016, on a plot of 2 ha of grape variety TorrontésRiojano, conducted in horizontal roof. The treatments consisted in the placement of traps, with a density of 100 bottles / ha, barley with food attractant: T1) ammonium phosphate (fertilizer 18-46-0) at a dilution of 1 kg / 20 L water and T2) trimethylamine 5.74% (Plus-Trap).To monitor the treatments, two pairs of Jackson and Mac Phail traps were placed in each plot. The variables were the index FTD (Fly / Trap / Day) weekly, the number of flies according to species and sex captured for each attractor; and the severity of damage from cluster to crop by grade (0, 1, 2, 3 and 4).The results showed that there are no significant differences (p≥0.05) for FTD between the two attractants, nor are there differences in catch per species, nor by sex among the attractants. Finally, the percentages with degrees of severe attack (3 and 4) were lower in the attractant trimethylamine with respect to the ammonium phosphate. It will be repeated in the next campaign.
