The aim of this work was to evaluate the effect of Planococcus ficus infection in red wine grapes on Aspergillus section Nigri and ochratoxin A (OTA) contamination. contamination. contamination. Aspergillus section Nigri and ochratoxin A (OTA) contamination. 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 the grape variety and the harvest season evaluated, Aspergillus section Nigri the grape variety and the harvest season evaluated, Aspergillus section Nigri the grape variety and the harvest season evaluated, Aspergillus section Nigri and Cabernet Sauvignon varieties divided into two categories of grape samples (undamaged and damaged by P. ficus) were evaluated.

Regardless of the grape variety and the harvest season evaluated, Aspergillus section NigriAspergillus section Nigri incidence and the mean OTA concentration in damaged berries were significantly higher than that in the undamaged ones (P < 0Æ05; P < 0Æ001). The Merlot variety showed the highest level of black aspergilli contamination in damaged grapes during the 2006 ⁄ 2007 vintage (53Æ5% of infection), whereas Malbec presented the highest incidence during the 2008 ⁄ 2009 vintage (57Æ6% of infection).

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. occurrence in grapes, suggesting the need to implement insect control at preharvest stage to reduce the entry of OTA in the wine production chain. occurrence in grapes, suggesting the need to implement insect control at preharvest stage to reduce the entry of OTA in the wine production chain.
