Methods and Results: During 2006 ⁄ 2007 and 2008 ⁄ 2009 vintages, Merlot, Malbec
and Cabernet Sauvignon varieties divided into two categories of grape
samples (undamaged and damaged by P. ficus) were evaluated. Regardless of

Conclusions: The presence of P. ficus in vineyards increased the risk of OTA
occurrence in grapes, suggesting the need to implement insect control at
preharvest stage to reduce the entry of OTA in the wine production chain.
